-If you just want to build and install the latest release, follow the simplified
-process described in [doc/linux.md](linux.md).
+
+## Simple
+
+If you just want to install the latest release from `master`, follow this
+simplified process.
+
+First, you need to install the required packages:
+
+```bash
+# for Debian/Ubuntu
+sudo apt install ffmpeg libsdl2-2.0-0 adb wget \
+                 gcc git pkg-config meson ninja-build libsdl2-dev \
+                 libavcodec-dev libavdevice-dev libavformat-dev libavutil-dev \
+                 libusb-1.0-0 libusb-1.0-0-dev
+```
+
+Then clone the repo and execute the installation script
+([source](install_release.sh)):
+
+```bash
+git clone https://github.com/Genymobile/scrcpy
+cd scrcpy
+./install_release.sh
+```
+
+When a new release is out, update the repo and reinstall:
+
+```bash
+git pull
+./install_release.sh
+```
+
+To uninstall:
+
+```bash
+sudo ninja -Cbuild-auto uninstall
+```
+
 
 ## Branches
 
-There are two main branches:
- - `master`: contains the latest release. It is the home page of the project on
-   GitHub.
- - `dev`: the current development branch. Every commit present in `dev` will be
-   in the next release.
+### `master`
+
+The `master` branch concerns the latest release, and is the home page of the
+project on Github.
+

+Questi sono i problemi più comuni riportati e i loro stati.
+
+
+## Problemi di `adb`
+
+`scrcpy` esegue comandi `adb` per inizializzare la connessione con il dispositivo. Se `adb` fallisce, scrcpy non funzionerà.
+
+In questo caso sarà stampato questo errore:
+
+>     ERROR: "adb push" returned with value 1
+
+Questo solitamente non è un bug di _scrcpy_, ma un problema del tuo ambiente.
+
+Per trovare la causa, esegui:
+
+```bash
+adb devices
+```
+
+### `adb` not found (`adb` non trovato)
+
+È necessario che `adb` sia accessibile dal tuo `PATH`.
+
+In Windows, la cartella corrente è nel tuo `PATH` e `adb.exe` è incluso nella release, perciò dovrebbe già essere pronto all'uso.
+
+
+### Device unauthorized (Dispositivo non autorizzato)
+
+Controlla [stackoverflow][device-unauthorized] (in inglese).
+
+[device-unauthorized]: https://stackoverflow.com/questions/23081263/adb-android-device-unauthorized
+
+
+### Device not detected (Dispositivo non rilevato)
+
+>     adb: error: failed to get feature set: no devices/emulators found
+
+Controlla di aver abilitato correttamente il [debug con adb][enable-adb] (link in inglese).
+
+Se il tuo dispositivo non è rilevato, potresti avere bisogno dei [driver][drivers] (link in inglese) (in Windows).
+
+[enable-adb]: https://developer.android.com/studio/command-line/adb.html#Enabling
+[drivers]: https://developer.android.com/studio/run/oem-usb.html
+
+
+### Più dispositivi connessi
+
+Se più dispositivi sono connessi, riscontrerai questo errore:
+
+>     adb: error: failed to get feature set: more than one device/emulator
+
+l'identificatore del tuo dispositivo deve essere fornito:
+
+```bash
+scrcpy -s 01234567890abcdef
+```
+
+Notare che se il tuo dispositivo è connesso mediante TCP/IP, riscontrerai questo messaggio:
+
+>     adb: error: more than one device/emulator
+>     ERROR: "adb reverse" returned with value 1
+>     WARN: 'adb reverse' failed, fallback to 'adb forward'
+
+Questo è un problema atteso (a causa di un bug di una vecchia versione di Android, vedi [#5] (link in inglese)), ma in quel caso scrcpy ripiega su un metodo differente, il quale dovrebbe funzionare.
+
+[#5]: https://github.com/Genymobile/scrcpy/issues/5
+
+
+### Conflitti tra versioni di adb
+
+>     adb server version (41) doesn't match this client (39); killing...
+
+L'errore compare quando usi più versioni di `adb` simultaneamente. Devi trovare il programma che sta utilizzando una versione differente di `adb` e utilizzare la stessa versione dappertutto.
+
+Puoi sovrascrivere i binari di `adb` nell'altro programma, oppure chiedere a _scrcpy_ di usare un binario specifico di `adb`, impostando la variabile d'ambiente `ADB`:
+
+```bash
+set ADB=/path/to/your/adb
+scrcpy
+```
+
+
+### Device disconnected (Dispositivo disconnesso)
+
+Se _scrcpy_ si interrompe con l'avviso "Device disconnected", allora la connessione `adb` è stata chiusa.
+
+Prova con un altro cavo USB o inseriscilo in un'altra porta USB. Vedi [#281] (in inglese) e [#283] (in inglese).

+## Problemi di controllo
+
+### Mouse e tastiera non funzionano
+
+Su alcuni dispositivi potresti dover abilitare un opzione che permette l'[input simulato][simulating input] (link in inglese). Nelle opzioni sviluppatore, abilita:
+
+> **Debug USB (Impostazioni di sicurezza)**
+> _Permetti la concessione dei permessi e la simulazione degli input mediante il debug USB_
+<!--- Ho tradotto personalmente il testo sopra, non conosco esattamente il testo reale --->
+
+[simulating input]: https://github.com/Genymobile/scrcpy/issues/70#issuecomment-373286323
+
+
+### I caratteri speciali non funzionano
+
+Iniettare del testo in input è [limitato ai caratteri ASCII][text-input] (link in inglese). Un trucco permette di iniettare dei [caratteri accentati][accented-characters] (link in inglese), ma questo è tutto. Vedi [#37] (link in inglese).

+[#37]: https://github.com/Genymobile/scrcpy/issues/37
+
+
+## Problemi del client
+
+### La qualità è bassa
+
+Se la definizione della finestra del tuo client è minore di quella del tuo dispositivo, allora potresti avere una bassa qualità di visualizzazione, specialmente individuabile nei testi (vedi [#40] (link in inglese)).
+
+[#40]: https://github.com/Genymobile/scrcpy/issues/40
+
+Per migliorare la qualità di ridimensionamento (downscaling), il filtro trilineare è applicato automaticamente se il renderizzatore è OpenGL e se supporta la creazione di mipmap.
+
+In Windows, potresti voler forzare OpenGL:
+
+```
+scrcpy --render-driver=opengl
+```
+
+Potresti anche dover configurare il [comportamento di ridimensionamento][scaling behavior] (link in inglese):
+
+> `scrcpy.exe` > Propietà > Compatibilità > Modifica impostazioni DPI elevati > Esegui l'override del comportamento di ridimensionamento DPI elevati >  Ridimensionamento eseguito per:  _Applicazione_.
+
+[scaling behavior]: https://github.com/Genymobile/scrcpy/issues/40#issuecomment-424466723
+
+
+### Problema con Wayland
+
+Per impostazione predefinita, SDL utilizza x11 su Linux. Il [video driver] può essere cambiato attraversio la variabile d'ambiente `SDL_VIDEODRIVER`:
+
+[video driver]: https://wiki.libsdl.org/FAQUsingSDL#how_do_i_choose_a_specific_video_driver
+
+```bash
+export SDL_VIDEODRIVER=wayland
+scrcpy
+```
+
+Su alcune distribuzioni (almeno Fedora), il pacchetto `libdecor` deve essere installato manualmente.
+
+Vedi le issues [#2554] e [#2559].

+[#2554]: https://github.com/Genymobile/scrcpy/issues/2554
+[#2559]: https://github.com/Genymobile/scrcpy/issues/2559
+
+
+### Crash del compositore KWin
+
+In Plasma Desktop, il compositore è disabilitato mentre _scrcpy_ è in esecuzione.
+
+Come soluzione alternativa, [disattiva la "composizione dei blocchi"][kwin] (link in inglese).
+<!--- Non sono sicuro di aver tradotto correttamente la stringa di testo del pulsante --->
+
+[kwin]: https://github.com/Genymobile/scrcpy/issues/114#issuecomment-378778613
+
+
+## Crash
+
+### Eccezione
+
+Ci potrebbero essere molte ragioni. Una causa comune è che il codificatore hardware del tuo dispositivo non riesce a codificare alla definizione selezionata:
+
+> ```
+> ERROR: Exception on thread Thread[main,5,main]
+> android.media.MediaCodec$CodecException: Error 0xfffffc0e
+> ...
+> Exit due to uncaughtException in main thread:
+> ERROR: Could not open video stream
+> INFO: Initial texture: 1080x2336
+> ```
+
+o
+
+> ```
+> ERROR: Exception on thread Thread[main,5,main]
+> java.lang.IllegalStateException
+>         at android.media.MediaCodec.native_dequeueOutputBuffer(Native Method)
+> ```
+
+Prova con una definizione inferiore:
+
+```
+scrcpy -m 1920
+scrcpy -m 1024
+scrcpy -m 800
+```
+
+Potresti anche provare un altro [codificatore](README.it.md#codificatore).
+
+
+## Linea di comando in Windows
+
+Alcuni utenti Windows non sono familiari con la riga di comando. Qui è descritto come aprire un terminale ed eseguire `scrcpy` con gli argomenti:
+
+ 1. Premi <kbd>Windows</kbd>+<kbd>r</kbd>, questo apre una finestra di dialogo.
+ 2. Scrivi `cmd` e premi <kbd>Enter</kbd>, questo apre un terminale.
+ 3. Vai nella tua cartella di _scrcpy_ scrivendo (adatta il percorso):
+
+    ```bat
+    cd C:\Users\user\Downloads\scrcpy-win64-xxx
+    ```
+
+    e premi <kbd>Enter</kbd>
+ 4. Scrivi il tuo comando. Per esempio:
+
+    ```bat
+    scrcpy --record file.mkv
+    ```
+
+Se pianifichi di utilizzare sempre gli stessi argomenti, crea un file `myscrcpy.bat` (abilita mostra [estensioni nomi file][show file extensions] per evitare di far confusione) contenente il tuo comando nella cartella di `scrcpy`. Per esempio:
+
+```bat
+scrcpy --prefer-text --turn-screen-off --stay-awake
+```
+
+Poi fai doppio click su quel file.
+
+Potresti anche modificare (una copia di) `scrcpy-console.bat` o `scrcpy-noconsole.vbs` per aggiungere alcuni argomenti.

+## Command line on Windows
+
+Some Windows users are not familiar with the command line. Here is how to open a
+terminal and run `scrcpy` with arguments:
+
+ 1. Press <kbd>Windows</kbd>+<kbd>r</kbd>, this opens a dialog box.
+ 2. Type `cmd` and press <kbd>Enter</kbd>, this opens a terminal.
+ 3. Go to your _scrcpy_ directory, by typing (adapt the path):
+
+    ```bat
+    cd C:\Users\user\Downloads\scrcpy-win64-xxx
+    ```
+
+    and press <kbd>Enter</kbd>
+ 4. Type your command. For example:
+
+    ```bat
+    scrcpy --record file.mkv
+    ```
+
+If you plan to always use the same arguments, create a file `myscrcpy.bat`
+(enable [show file extensions] to avoid confusion) in the `scrcpy` directory,
+containing your command. For example:
+
+```bat
+scrcpy --prefer-text --turn-screen-off --stay-awake
+```
+
+Then just double-click on that file.
+
+You could also edit (a copy of) `scrcpy-console.bat` or `scrcpy-noconsole.vbs`
+to add some arguments.

+
+# 常见问题
+
+这里是一些常见的问题以及他们的状态。
+
+## `adb` 相关问题
+
+`scrcpy` 执行 `adb` 命令来初始化和设备之间的连接。如果`adb` 执行失败了， scrcpy 就无法工作。
+
+在这种情况中，将会输出这个错误:
+
+>     ERROR: "adb push" returned with value 1
+
+这通常不是 _scrcpy_ 的bug，而是你的环境的问题。
+
+要找出原因，请执行以下操作：
+
+```bash
+adb devices
+```
+
+### 找不到`adb`
+
+
+你的`PATH`中需要能访问到`adb`。
+
+在Windows上，当前目录会包含在`PATH`中，并且`adb.exe`也包含在发行版中，因此它应该是开箱即用（直接解压就可以）的。
+
+
+### 设备未授权
+
+参见这里 [stackoverflow][device-unauthorized].
+
+[device-unauthorized]: https://stackoverflow.com/questions/23081263/adb-android-device-unauthorized
+
+
+### 未检测到设备
+
+>     adb: error: failed to get feature set: no devices/emulators found
+
+确认已经正确启用 [adb debugging][enable-adb].
+
+如果你的设备没有被检测到，你可能需要一些[驱动][drivers] (在 Windows上).
+
+[enable-adb]: https://developer.android.com/studio/command-line/adb.html#Enabling
+[drivers]: https://developer.android.com/studio/run/oem-usb.html
+
+
+### 已连接多个设备
+
+如果连接了多个设备，您将遇到以下错误：
+
+>     adb: error: failed to get feature set: more than one device/emulator
+
+必须提供要镜像的设备的标识符：
+
+```bash
+scrcpy -s 01234567890abcdef
+```
+
+注意，如果你的设备是通过 TCP/IP 连接的， 你将会收到以下消息：
+
+>     adb: error: more than one device/emulator
+>     ERROR: "adb reverse" returned with value 1
+>     WARN: 'adb reverse' failed, fallback to 'adb forward'
+
+这是意料之中的 (由于旧版安卓的一个bug, 请参见 [#5])，但是在这种情况下，scrcpy会退回到另一种方法，这种方法应该可以起作用。
+
+[#5]: https://github.com/Genymobile/scrcpy/issues/5
+
+
+### adb版本之间冲突
+
+>     adb server version (41) doesn't match this client (39); killing...
+
+同时使用多个版本的`adb`时会发生此错误。你必须查找使用不同`adb`版本的程序，并在所有地方使用相同版本的`adb`。
+
+你可以覆盖另一个程序中的`adb`二进制文件，或者通过设置`ADB`环境变量来让 _scrcpy_ 使用特定的`adb`二进制文件。
+
+```bash
+set ADB=/path/to/your/adb
+scrcpy
+```
+
+
+### 设备断开连接
+
+如果 _scrcpy_ 在警告“设备连接断开”的情况下自动中止，那就意味着`adb`连接已经断开了。
+请尝试使用另一条USB线或者电脑上的另一个USB接口。
+请参看 [#281] 和 [#283]。
+
+[#281]: https://github.com/Genymobile/scrcpy/issues/281
+[#283]: https://github.com/Genymobile/scrcpy/issues/283
+
+## 控制相关问题
+
+### 鼠标和键盘不起作用
+
+
+在某些设备上，您可能需要启用一个选项以允许 [模拟输入][simulating input]。
+
+在开发者选项中，打开：
+
+> **USB调试 (安全设置)**  
+> _允许通过USB调试修改权限或模拟点击_
+
+[simulating input]: https://github.com/Genymobile/scrcpy/issues/70#issuecomment-373286323
+
+
+### 特殊字符不起作用
+
+可输入的文本[被限制为ASCII字符][text-input]。也可以用一些小技巧输入一些[带重音符号的字符][accented-characters]，但是仅此而已。参见[#37]。
+
+
+[text-input]: https://github.com/Genymobile/scrcpy/issues?q=is%3Aopen+is%3Aissue+label%3Aunicode
+[accented-characters]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-accented-characters
+[#37]: https://github.com/Genymobile/scrcpy/issues/37
+
+
+## 客户端相关问题
+
+### 效果很差
+
+如果你的客户端窗口分辨率比你的设备屏幕小，则可能出现效果差的问题，尤其是在文本上（参见 [#40]）。
+
+[#40]: https://github.com/Genymobile/scrcpy/issues/40
+
+
+为了提升降尺度的质量，如果渲染器是OpenGL并且支持mip映射，就会自动开启三线性过滤。
+
+在Windows上，你可能希望强制使用OpenGL：
+
+```
+scrcpy --render-driver=opengl
+```
+
+你可能还需要配置[缩放行为][scaling behavior]：
+
+> `scrcpy.exe` > Properties > Compatibility > Change high DPI settings >
+> Override high DPI scaling behavior > Scaling performed by: _Application_.
+
+[scaling behavior]: https://github.com/Genymobile/scrcpy/issues/40#issuecomment-424466723
+
+
+### Wayland相关的问题
+
+在Linux上，SDL默认使用x11。可以通过`SDL_VIDEODRIVER`环境变量来更改[视频驱动][video driver]：
+
+[video driver]: https://wiki.libsdl.org/FAQUsingSDL#how_do_i_choose_a_specific_video_driver
+
+```bash
+export SDL_VIDEODRIVER=wayland
+scrcpy
+```
+
+在一些发行版上 (至少包括 Fedora)， `libdecor` 包必须手动安装。
+
+参见 [#2554] 和 [#2559]。
+
+[#2554]: https://github.com/Genymobile/scrcpy/issues/2554
+[#2559]: https://github.com/Genymobile/scrcpy/issues/2559
+
+
+### KWin compositor 崩溃
+
+在Plasma桌面中，当 _scrcpy_ 运行时，会禁用compositor。
+
+一种解决方法是， [禁用 "Block compositing"][kwin].
+
+[kwin]: https://github.com/Genymobile/scrcpy/issues/114#issuecomment-378778613
+
+
+## 崩溃
+
+### 异常
+可能有很多原因。一个常见的原因是您的设备无法按给定清晰度进行编码：
+
+> ```
+> ERROR: Exception on thread Thread[main,5,main]
+> android.media.MediaCodec$CodecException: Error 0xfffffc0e
+> ...
+> Exit due to uncaughtException in main thread:
+> ERROR: Could not open video stream
+> INFO: Initial texture: 1080x2336
+> ```
+
+或者
+
+> ```
+> ERROR: Exception on thread Thread[main,5,main]
+> java.lang.IllegalStateException
+>         at android.media.MediaCodec.native_dequeueOutputBuffer(Native Method)
+> ```
+
+请尝试使用更低的清晰度：
+
+```
+scrcpy -m 1920
+scrcpy -m 1024
+scrcpy -m 800
+```
+
+你也可以尝试另一种 [编码器](README.md#encoder)。
+
+
+## Windows命令行
+
+一些Windows用户不熟悉命令行。以下是如何打开终端并带参数执行`scrcpy`：
+
+ 1. 按下 <kbd>Windows</kbd>+<kbd>r</kbd>，打开一个对话框。
+ 2. 输入 `cmd` 并按 <kbd>Enter</kbd>，这样就打开了一个终端。
+ 3. 通过输入以下命令，切换到你的 _scrcpy_ 所在的目录 （根据你的实际位置修改路径）:
+
+    ```bat
+    cd C:\Users\user\Downloads\scrcpy-win64-xxx
+    ```
+
+    然后按 <kbd>Enter</kbd>
+ 4. 输入你的命令。比如:
+
+    ```bat
+    scrcpy --record file.mkv
+    ```
+
+如果你打算总是使用相同的参数，在`scrcpy`目录创建一个文件 `myscrcpy.bat`
+（启用 [显示文件拓展名][show file extensions] 避免混淆），文件中包含你的命令。例如：
+
+```bat
+scrcpy --prefer-text --turn-screen-off --stay-awake
+```
+
+然后双击刚刚创建的文件。
+
+你也可以编辑 `scrcpy-console.bat` 或者 `scrcpy-noconsole.vbs`（的副本）来添加参数。

+# scrcpy (v1.16)
+
+Aplikasi ini menyediakan tampilan dan kontrol perangkat Android yang terhubung pada USB (atau [melalui TCP/IP][article-tcpip]). Ini tidak membutuhkan akses _root_ apa pun. Ini bekerja pada _GNU/Linux_, _Windows_ and _macOS_.
+
+![screenshot](assets/screenshot-debian-600.jpg)
+
+Ini berfokus pada:
+
+  - **keringanan** (asli, hanya menampilkan layar perangkat)
+  - **kinerja** (30~60fps)
+  - **kualitas** (1920×1080 atau lebih)
+  - **latensi** rendah ([35~70ms][lowlatency])
+  - **waktu startup rendah** (~1 detik untuk menampilkan gambar pertama)
+  - **tidak mengganggu** (tidak ada yang terpasang di perangkat)
+
+
+[lowlatency]: https://github.com/Genymobile/scrcpy/pull/646
+
+
+## Persyaratan
+Perangkat Android membutuhkan setidaknya API 21 (Android 5.0).
+
+Pastikan Anda [mengaktifkan debugging adb][enable-adb] pada perangkat Anda.
+
+[enable-adb]: https://developer.android.com/studio/command-line/adb.html#Enabling
+
+Di beberapa perangkat, Anda juga perlu mengaktifkan [opsi tambahan][control] untuk mengontrolnya menggunakan keyboard dan mouse.

+
+Anda juga bisa [membangun aplikasi secara manual][BUILD] (jangan khawatir, tidak terlalu sulit).
+
+
+### Windows
+
+Untuk Windows, untuk kesederhanaan, arsip prebuilt dengan semua dependensi (termasuk `adb`) tersedia :
+
+ - [README](README.md#windows)
+
+Ini juga tersedia di [Chocolatey]:
+
+[Chocolatey]: https://chocolatey.org/
+
+```bash
+choco install scrcpy
+choco install adb    # jika Anda belum memilikinya
+```
+
+Dan di [Scoop]:
+
+```bash
+scoop install scrcpy
+scoop install adb    # jika Anda belum memilikinya
+```
+
+[Scoop]: https://scoop.sh
+
+Anda juga dapat [membangun aplikasi secara manual][BUILD].
+
+
+### macOS
+
+Aplikasi ini tersedia di [Homebrew]. Instal saja:
+
+[Homebrew]: https://brew.sh/
+
+```bash
+brew install scrcpy
+```
+Anda membutuhkan `adb`, dapat diakses dari `PATH` Anda. Jika Anda belum memilikinya:
+
+```bash
+brew cask install android-platform-tools
+```
+
+Anda juga dapat [membangun aplikasi secara manual][BUILD].
+
+
+## Menjalankan
+
+Pasang perangkat Android, dan jalankan:
+
+```bash
+scrcpy
+```
+
+Ini menerima argumen baris perintah, didaftarkan oleh:
+
+```bash
+scrcpy --help
+```
+
+## Fitur
+
+### Menangkap konfigurasi
+
+#### Mengurangi ukuran
+
+Kadang-kadang, berguna untuk mencerminkan perangkat Android dengan definisi yang lebih rendah untuk meningkatkan kinerja.
+
+Untuk membatasi lebar dan tinggi ke beberapa nilai (mis. 1024):
+
+```bash
+scrcpy --max-size 1024
+scrcpy -m 1024  # versi pendek
+```
+
+Dimensi lain dihitung agar rasio aspek perangkat dipertahankan.
+Dengan begitu, perangkat 1920×1080 akan dicerminkan pada 1024×576.
+
+#### Ubah kecepatan bit
+
+Kecepatan bit default adalah 8 Mbps. Untuk mengubah bitrate video (mis. Menjadi 2 Mbps):
+
+```bash
+scrcpy --bit-rate 2M
+scrcpy -b 2M  # versi pendek
+```
+
+#### Batasi frekuensi gambar
+
+Kecepatan bingkai pengambilan dapat dibatasi:
+
+```bash
+scrcpy --max-fps 15
+```
+
+Ini secara resmi didukung sejak Android 10, tetapi dapat berfungsi pada versi sebelumnya.
+
+#### Memotong
+
+Layar perangkat dapat dipotong untuk mencerminkan hanya sebagian dari layar.
+
+Ini berguna misalnya untuk mencerminkan hanya satu mata dari Oculus Go:
+
+```bash
+scrcpy --crop 1224:1440:0:0   # 1224x1440 Mengimbangi (0,0)
+```
+
+Jika `--max-size` juga ditentukan, pengubahan ukuran diterapkan setelah pemotongan.
+
+
+#### Kunci orientasi video
+
+Untuk mengunci orientasi pencerminan:
+
+```bash
+scrcpy --lock-video-orientation 0   # orientasi alami
+scrcpy --lock-video-orientation 1   # 90° berlawanan arah jarum jam
+scrcpy --lock-video-orientation 2   # 180°
+scrcpy --lock-video-orientation 3   # 90° searah jarum jam
+```
+
+Ini mempengaruhi orientasi perekaman.
+
+
+### Rekaman
+
+Anda dapat merekam layar saat melakukan mirroring:
+
+```bash
+scrcpy --record file.mp4
+scrcpy -r file.mkv
+```
+
+Untuk menonaktifkan pencerminan saat merekam:
+
+```bash
+scrcpy --no-display --record file.mp4
+scrcpy -Nr file.mkv
+# berhenti merekam dengan Ctrl+C
+```
+
+"Skipped frames" are recorded, even if they are not displayed in real time (for
+performance reasons). Frames are _timestamped_ on the device, so [packet delay
+variation] does not impact the recorded file.
+
+"Frame yang dilewati" direkam, meskipun tidak ditampilkan secara real time (untuk alasan performa). Bingkai *diberi stempel waktu* pada perangkat, jadi [variasi penundaan paket] tidak memengaruhi file yang direkam.
+
+[variasi penundaan paket]: https://en.wikipedia.org/wiki/Packet_delay_variation
+
+
+### Koneksi
+
+#### Wireless
+
+_Scrcpy_ menggunakan `adb` untuk berkomunikasi dengan perangkat, dan` adb` dapat [terhubung] ke perangkat melalui TCP / IP:
+
+1. Hubungkan perangkat ke Wi-Fi yang sama dengan komputer Anda.
+2. Dapatkan alamat IP perangkat Anda (dalam Pengaturan → Tentang ponsel → Status).
+3. Aktifkan adb melalui TCP / IP pada perangkat Anda: `adb tcpip 5555`.
+4. Cabut perangkat Anda.
+5. Hubungkan ke perangkat Anda: `adb connect DEVICE_IP: 5555` (*ganti* *`DEVICE_IP`*).
+6. Jalankan `scrcpy` seperti biasa.
+
+Mungkin berguna untuk menurunkan kecepatan bit dan definisi:
+
+```bash
+scrcpy --bit-rate 2M --max-size 800
+scrcpy -b2M -m800  # versi pendek
+```
+
+[terhubung]: https://developer.android.com/studio/command-line/adb.html#wireless
+
+
+#### Multi-perangkat
+
+Jika beberapa perangkat dicantumkan di `adb devices`, Anda harus menentukan _serial_:
+
+```bash
+scrcpy --serial 0123456789abcdef
+scrcpy -s 0123456789abcdef  # versi pendek
+```
+
+If the device is connected over TCP/IP:
+
+```bash
+scrcpy --serial 192.168.0.1:5555
+scrcpy -s 192.168.0.1:5555  # versi pendek
+```
+
+Anda dapat memulai beberapa contoh _scrcpy_ untuk beberapa perangkat.
+
+#### Mulai otomatis pada koneksi perangkat
+
+Anda bisa menggunakan [AutoAdb]:
+
+```bash
+autoadb scrcpy -s '{}'
+```
+
+[AutoAdb]: https://github.com/rom1v/autoadb
+
+#### Koneksi via SSH tunnel
+
+Untuk menyambung ke perangkat jarak jauh, dimungkinkan untuk menghubungkan klien `adb` lokal ke server `adb` jarak jauh (asalkan mereka menggunakan versi yang sama dari _adb_ protocol):
+
+```bash
+adb kill-server    # matikan server adb lokal di 5037
+ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 komputer_jarak_jauh_anda
+# jaga agar tetap terbuka
+```
+
+Dari terminal lain:
+
+```bash
+scrcpy
+```
+
+Untuk menghindari mengaktifkan penerusan port jarak jauh, Anda dapat memaksa sambungan maju sebagai gantinya (perhatikan `-L`, bukan` -R`):
+
+```bash
+adb kill-server    # matikan server adb lokal di 5037
+ssh -CN -L5037:localhost:5037 -L27183:localhost:27183 komputer_jarak_jauh_anda
+# jaga agar tetap terbuka
+```
+
+Dari terminal lain:
+
+```bash
+scrcpy --force-adb-forward
+```
+
+Seperti koneksi nirkabel, mungkin berguna untuk mengurangi kualitas:
+
+```
+scrcpy -b2M -m800 --max-fps 15
+```
+
+### Konfigurasi Jendela
+
+#### Judul
+
+Secara default, judul jendela adalah model perangkat. Itu bisa diubah:
+
+```bash
+scrcpy --window-title 'Perangkat Saya'
+```
+
+#### Posisi dan ukuran
+
+Posisi dan ukuran jendela awal dapat ditentukan:
+
+```bash
+scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
+```
+
+#### Jendela tanpa batas
+
+Untuk menonaktifkan dekorasi jendela:
+
+```bash
+scrcpy --window-borderless
+```
+
+#### Selalu di atas
+
+Untuk menjaga jendela scrcpy selalu di atas:
+
+```bash
+scrcpy --always-on-top
+```
+
+#### Layar penuh
+
+Aplikasi dapat dimulai langsung dalam layar penuh::
+
+```bash
+scrcpy --fullscreen
+scrcpy -f  # versi pendek
+```
+
+Layar penuh kemudian dapat diubah secara dinamis dengan <kbd>MOD</kbd>+<kbd>f</kbd>.
+
+#### Rotasi
+
+Jendela mungkin diputar:
+
+```bash
+scrcpy --rotation 1
+```
+
+Nilai yang mungkin adalah:
+ - `0`: tidak ada rotasi
+ - `1`: 90 derajat berlawanan arah jarum jam
+ - `2`: 180 derajat
+ - `3`: 90 derajat searah jarum jam
+
+Rotasi juga dapat diubah secara dinamis dengan <kbd>MOD</kbd>+<kbd>←</kbd>
+_(kiri)_ and <kbd>MOD</kbd>+<kbd>→</kbd> _(kanan)_.
+
+Perhatikan bahwa _scrcpy_ mengelola 3 rotasi berbeda::
+ - <kbd>MOD</kbd>+<kbd>r</kbd> meminta perangkat untuk beralih antara potret dan lanskap (aplikasi yang berjalan saat ini mungkin menolak, jika mendukung orientasi yang diminta).
+ - `--lock-video-orientation` mengubah orientasi pencerminan (orientasi video yang dikirim dari perangkat ke komputer). Ini mempengaruhi rekaman.
+ - `--rotation` (atau <kbd>MOD</kbd>+<kbd>←</kbd>/<kbd>MOD</kbd>+<kbd>→</kbd>)
+   memutar hanya konten jendela. Ini hanya mempengaruhi tampilan, bukan rekaman.
+
+
+### Opsi pencerminan lainnya
+
+#### Hanya-baca
+
+Untuk menonaktifkan kontrol (semua yang dapat berinteraksi dengan perangkat: tombol input, peristiwa mouse, seret & lepas file):
+
+```bash
+scrcpy --no-control
+scrcpy -n
+```
+
+#### Layar
+
+Jika beberapa tampilan tersedia, Anda dapat memilih tampilan untuk cermin:
+
+```bash
+scrcpy --display 1
+```
+
+Daftar id tampilan dapat diambil dengan::
+
+```
+adb shell dumpsys display   # cari "mDisplayId=" di keluaran
+```
+
+Tampilan sekunder hanya dapat dikontrol jika perangkat menjalankan setidaknya Android 10 (jika tidak maka akan dicerminkan dalam hanya-baca).
+
+
+#### Tetap terjaga
+
+Untuk mencegah perangkat tidur setelah beberapa penundaan saat perangkat dicolokkan:
+
+```bash
+scrcpy --stay-awake
+scrcpy -w
+```
+
+Keadaan awal dipulihkan ketika scrcpy ditutup.
+
+
+#### Matikan layar
+
+Dimungkinkan untuk mematikan layar perangkat saat pencerminan mulai dengan opsi baris perintah:
+
+```bash
+scrcpy --turn-screen-off
+scrcpy -S
+```
+
+Atau dengan menekan <kbd>MOD</kbd>+<kbd>o</kbd> kapan saja.
+
+Untuk menyalakannya kembali, tekan <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>o</kbd>.
+
+Di Android, tombol `POWER` selalu menyalakan layar. Untuk kenyamanan, jika `POWER` dikirim melalui scrcpy (melalui klik kanan atau<kbd>MOD</kbd>+<kbd>p</kbd>), itu akan memaksa untuk mematikan layar setelah penundaan kecil (atas dasar upaya terbaik).
+Tombol fisik `POWER` masih akan menyebabkan layar dihidupkan.
+
+Ini juga berguna untuk mencegah perangkat tidur:
+
+```bash
+scrcpy --turn-screen-off --stay-awake
+scrcpy -Sw
+```
+
+#### Render frame kedaluwarsa
+
+Secara default, untuk meminimalkan latensi, _scrcpy_ selalu menampilkan frame yang terakhir didekodekan tersedia, dan menghapus frame sebelumnya.
+
+Untuk memaksa rendering semua frame (dengan kemungkinan peningkatan latensi), gunakan:
+
+```bash
+scrcpy --render-expired-frames
+```
+
+#### Tunjukkan sentuhan
+
+Untuk presentasi, mungkin berguna untuk menunjukkan sentuhan fisik (pada perangkat fisik).
+
+Android menyediakan fitur ini di _Opsi Pengembang_.
+
+_Scrcpy_ menyediakan opsi untuk mengaktifkan fitur ini saat mulai dan mengembalikan nilai awal saat keluar:
+
+```bash
+scrcpy --show-touches
+scrcpy -t
+```
+
+Perhatikan bahwa ini hanya menunjukkan sentuhan _fisik_ (dengan jari di perangkat).
+
+
+#### Nonaktifkan screensaver
+
+Secara default, scrcpy tidak mencegah screensaver berjalan di komputer.
+
+Untuk menonaktifkannya:
+
+```bash
+scrcpy --disable-screensaver
+```
+
+
+### Kontrol masukan
+
+#### Putar layar perangkat
+
+Tekan <kbd>MOD</kbd>+<kbd>r</kbd> untuk beralih antara mode potret dan lanskap.
+
+Perhatikan bahwa itu berputar hanya jika aplikasi di latar depan mendukung orientasi yang diminta.
+
+#### Salin-tempel
+
+Setiap kali papan klip Android berubah, secara otomatis disinkronkan ke papan klip komputer.
+
+Apa saja <kbd>Ctrl</kbd> pintasan diteruskan ke perangkat. Khususnya:
+ - <kbd>Ctrl</kbd>+<kbd>c</kbd> biasanya salinan
+ - <kbd>Ctrl</kbd>+<kbd>x</kbd> biasanya memotong
+ - <kbd>Ctrl</kbd>+<kbd>v</kbd> biasanya menempel (setelah sinkronisasi papan klip komputer-ke-perangkat)
+
+Ini biasanya berfungsi seperti yang Anda harapkan.
+
+Perilaku sebenarnya tergantung pada aplikasi yang aktif. Sebagai contoh,
+_Termux_ mengirim SIGINT ke <kbd>Ctrl</kbd>+<kbd>c</kbd> sebagai gantinya, dan _K-9 Mail_ membuat pesan baru.
+
+Untuk menyalin, memotong dan menempel dalam kasus seperti itu (tetapi hanya didukung di Android> = 7):
+ - <kbd>MOD</kbd>+<kbd>c</kbd> injeksi `COPY` _(salin)_
+ - <kbd>MOD</kbd>+<kbd>x</kbd> injeksi `CUT` _(potong)_
+ - <kbd>MOD</kbd>+<kbd>v</kbd> injeksi `PASTE` (setelah sinkronisasi papan klip komputer-ke-perangkat)
+
+Tambahan, <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd> memungkinkan untuk memasukkan teks papan klip komputer sebagai urutan peristiwa penting. Ini berguna ketika komponen tidak menerima penempelan teks (misalnya di _Termux_), tetapi dapat merusak konten non-ASCII.
+
+**PERINGATAN:** Menempelkan papan klip komputer ke perangkat (baik melalui
+<kbd>Ctrl</kbd>+<kbd>v</kbd> or <kbd>MOD</kbd>+<kbd>v</kbd>) menyalin konten ke clipboard perangkat. Akibatnya, aplikasi Android apa pun dapat membaca kontennya. Anda harus menghindari menempelkan konten sensitif (seperti kata sandi) seperti itu.
+
+
+#### Cubit untuk memperbesar/memperkecil
+
+Untuk mensimulasikan "cubit-untuk-memperbesar/memperkecil": <kbd>Ctrl</kbd>+_klik-dan-pindah_.
+
+Lebih tepatnya, tahan <kbd>Ctrl</kbd> sambil menekan tombol klik kiri. Hingga tombol klik kiri dilepaskan, semua gerakan mouse berskala dan memutar konten (jika didukung oleh aplikasi) relatif ke tengah layar.
+
+Secara konkret, scrcpy menghasilkan kejadian sentuh tambahan dari "jari virtual" di lokasi yang dibalik melalui bagian tengah layar.
+
+
+#### Preferensi injeksi teks
+
+Ada dua jenis [peristiwa][textevents] dihasilkan saat mengetik teks:
+- _peristiwa penting_, menandakan bahwa tombol ditekan atau dilepaskan;
+- _peristiwa teks_, menandakan bahwa teks telah dimasukkan.
+
+Secara default, huruf dimasukkan menggunakan peristiwa kunci, sehingga keyboard berperilaku seperti yang diharapkan dalam game (biasanya untuk tombol WASD).
+
+Tapi ini mungkin [menyebabkan masalah][prefertext]. Jika Anda mengalami masalah seperti itu, Anda dapat menghindarinya dengan:
+
+```bash
+scrcpy --prefer-text
+```
+
+(tapi ini akan merusak perilaku keyboard dalam game)
+
+[textevents]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-text-input
+[prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343
+
+
+#### Ulangi kunci
+
+Secara default, menahan tombol akan menghasilkan peristiwa kunci yang berulang. Ini dapat menyebabkan masalah kinerja di beberapa game, di mana acara ini tidak berguna.
+
+Untuk menghindari penerusan peristiwa penting yang berulang:
+
+```bash
+scrcpy --no-key-repeat
+```
+
+
+### Seret/jatuhkan file
+
+#### Pasang APK
+
+Untuk menginstal APK, seret & lepas file APK (diakhiri dengan `.apk`) ke jendela _scrcpy_.
+
+Tidak ada umpan balik visual, log dicetak ke konsol.
+
+
+#### Dorong file ke perangkat
+
+Untuk mendorong file ke `/sdcard/` di perangkat, seret & jatuhkan file (non-APK) ke jendela _scrcpy_.
+
+Tidak ada umpan balik visual, log dicetak ke konsol.
+
+Direktori target dapat diubah saat mulai:
+
+```bash
+scrcpy --push-target /sdcard/foo/bar/
+```
+
+
+### Penerusan audio
+
+Audio tidak diteruskan oleh _scrcpy_. Gunakan [sndcpy].
+
+Lihat juga [Masalah #14].

+[sndcpy]: https://github.com/rom1v/sndcpy
+[Masalah #14]: https://github.com/Genymobile/scrcpy/issues/14
+
+
+## Pintasan
+
+Dalam daftar berikut, <kbd>MOD</kbd> adalah pengubah pintasan. Secara default, ini (kiri) <kbd>Alt</kbd> atau (kiri) <kbd>Super</kbd>.
+
+Ini dapat diubah menggunakan `--shortcut-mod`. Kunci yang memungkinkan adalah `lctrl`,`rctrl`, `lalt`,` ralt`, `lsuper` dan` rsuper`. Sebagai contoh:
+
+```bash
+# gunakan RCtrl untuk jalan pintas
+scrcpy --shortcut-mod=rctrl
+
+# gunakan baik LCtrl+LAlt atau LSuper untuk jalan pintas
+scrcpy --shortcut-mod=lctrl+lalt,lsuper
+```
+
+_<kbd>[Super]</kbd> biasanya adalah <kbd>Windows</kbd> atau <kbd>Cmd</kbd> key._

+# scrcpy (v1.19)
+
+Questa applicazione fornisce la visualizzazione e il controllo dei dispositivi Android collegati via USB (o [via TCP/IP][article-tcpip]). Non richiede alcun accesso _root_.
+Funziona su _GNU/Linux_, _Windows_ e _macOS_.
+
+![screenshot](assets/screenshot-debian-600.jpg)
+
+Si concentra su:
+
+ - **leggerezza** (nativo, mostra solo lo schermo del dispositivo)
+ - **prestazioni** (30~60fps)
+ - **qualità** (1920×1080 o superiore)
+ - **bassa latenza** ([35~70ms][lowlatency])
+ - **tempo di avvio basso** (~ 1secondo per visualizzare la prima immagine)
+ - **non invadenza** (nulla viene lasciato installato sul dispositivo)
+
+[lowlatency]: https://github.com/Genymobile/scrcpy/pull/646
+
+
+## Requisiti
+
+Il dispositivo Android richiede almeno le API 21 (Android 5.0).
+
+Assiucurati di aver [attivato il debug usb][enable-adb] sul(/i) tuo(i) dispositivo(/i).
+
+[enable-adb]: https://developer.android.com/studio/command-line/adb.html#Enabling
+
+In alcuni dispositivi, devi anche abilitare [un'opzione aggiuntiva][control] per controllarli con tastiera e mouse.

+
+
+## Esecuzione
+
+Collega un dispositivo Android ed esegui:
+
+```bash
+scrcpy
+```
+
+Scrcpy accetta argomenti da riga di comando, essi sono listati con:
+
+```bash
+scrcpy --help
+```
+
+## Funzionalità
+
+### Configurazione di acquisizione
+
+#### Riduci dimensione
+
+Qualche volta è utile trasmettere un dispositvo Android ad una definizione inferiore per aumentare le prestazioni.
+
+Per limitare sia larghezza che altezza ad un certo valore (ad es. 1024):
+
+```bash
+scrcpy --max-size 1024
+scrcpy -m 1024  # versione breve
+```
+
+L'altra dimensione è calcolata in modo tale che il rapporto di forma del dispositivo sia preservato.
+In questo esempio un dispositivo in 1920x1080 viene trasmesso a 1024x576.
+
+
+#### Cambia bit-rate (velocità di trasmissione)
+
+Il bit-rate predefinito è 8 Mbps. Per cambiare il bitrate video (ad es. a 2 Mbps):
+
+```bash
+scrcpy --bit-rate 2M
+scrcpy -b 2M  # versione breve
+```
+
+#### Limitare il frame rate (frequenza di fotogrammi)
+
+Il frame rate di acquisizione può essere limitato:
+
+```bash
+scrcpy --max-fps 15
+```
+
+Questo è supportato ufficialmente a partire da Android 10, ma potrebbe funzionare in versioni precedenti.
+
+#### Ritaglio
+
+Lo schermo del dispositivo può essere ritagliato per visualizzare solo parte di esso.
+
+Questo può essere utile, per esempio, per trasmettere solo un occhio dell'Oculus Go:
+
+```bash
+scrcpy --crop 1224:1440:0:0   # 1224x1440 at offset (0,0)
+```
+
+Se anche `--max-size` è specificata, il ridimensionamento è applicato dopo il ritaglio.
+
+
+#### Blocca orientamento del video
+
+
+Per bloccare l'orientamento della trasmissione:
+
+```bash
+scrcpy --lock-video-orientation     # orientamento iniziale (corrente)
+scrcpy --lock-video-orientation=0   # orientamento naturale
+scrcpy --lock-video-orientation=1   # 90° antiorario
+scrcpy --lock-video-orientation=2   # 180°
+scrcpy --lock-video-orientation=3   # 90° orario
+```
+
+Questo influisce sull'orientamento della registrazione.
+
+
+La [finestra può anche essere ruotata](#rotazione) indipendentemente.
+
+
+#### Codificatore
+
+Alcuni dispositivi hanno più di un codificatore e alcuni di questi possono provocare problemi o crash. È possibile selezionare un encoder diverso:
+
+```bash
+scrcpy --encoder OMX.qcom.video.encoder.avc
+```
+
+Per elencare i codificatori disponibili puoi immettere un nome di codificatore non valido e l'errore mostrerà i codificatori disponibili:
+
+```bash
+scrcpy --encoder _
+```
+
+### Cattura
+
+#### Registrazione
+
+È possibile registrare lo schermo durante la trasmissione:
+
+```bash
+scrcpy --record file.mp4
+scrcpy -r file.mkv
+```
+
+Per disabilitare la trasmissione durante la registrazione:
+
+```bash
+scrcpy --no-display --record file.mp4
+scrcpy -Nr file.mkv
+# interrompere la registrazione con Ctrl+C
+```
+
+I "fotogrammi saltati" sono registrati nonostante non siano mostrati in tempo reale (per motivi di prestazioni). I fotogrammi sono _datati_ sul dispositivo, così una [variazione di latenza dei pacchetti][packet delay variation] non impatta il file registrato.
+
+[packet delay variation]: https://en.wikipedia.org/wiki/Packet_delay_variation
+
+
+#### v4l2loopback
+
+Su Linux è possibile inviare il flusso video ad un dispositivo v4l2 loopback, cosicchè un dispositivo Android possa essere aperto come una webcam da qualsiasi strumento compatibile con v4l2.
+
+Il modulo `v4l2loopback` deve essere installato:
+
+```bash
+sudo apt install v4l2loopback-dkms
+```
+
+Per creare un dispositvo v4l2:
+
+```bash
+sudo modprobe v4l2loopback
+```
+
+Questo creerà un nuovo dispositivo video in `/dev/videoN` dove `N` è un intero (più [opzioni](https://github.com/umlaeute/v4l2loopback#options) sono disponibili per crere più dispositivi o dispositivi con ID specifici).
+
+Per elencare i dispositvi attivati:
+
+```bash
+# necessita del pacchetto v4l-utils
+v4l2-ctl --list-devices
+
+# semplice ma potrebbe essere sufficiente
+ls /dev/video*
+```
+
+Per avviare scrcpy utilizzando un v4l2 sink:
+
+```bash
+scrcpy --v4l2-sink=/dev/videoN
+scrcpy --v4l2-sink=/dev/videoN --no-display  # disabilita la finestra di trasmissione
+scrcpy --v4l2-sink=/dev/videoN -N            # versione corta
+```
+
+(sostituisci `N` con l'ID del dispositivo, controlla con `ls /dev/video*`)
+
+Una volta abilitato, puoi aprire il tuo flusso video con uno strumento compatibile con v4l2:
+
+```bash
+ffplay -i /dev/videoN
+vlc v4l2:///dev/videoN   # VLC potrebbe aggiungere del ritardo per il buffer
+```
+
+Per esempio potresti catturare il video in [OBS].
+
+[OBS]: https://obsproject.com/
+
+
+#### Buffering
+
+È possibile aggiungere del buffer. Questo aumenta la latenza ma riduce il jitter (vedi [#2464]).
+
+[#2464]: https://github.com/Genymobile/scrcpy/issues/2464
+
+L'opzione è disponibile per il buffer della visualizzazione:
+
+```bash
+scrcpy --display-buffer=50  # aggiungi 50 ms di buffer per la visualizzazione
+```
+
+e per il V4L2 sink:
+
+```bash
+scrcpy --v4l2-buffer=500    #  aggiungi 50 ms di buffer per il v4l2 sink
+```
+
+
+### Connessione
+
+#### Wireless
+
+
+_Scrcpy_ usa `adb` per comunicare col dispositivo e `adb` può [connettersi][connect] al dispositivo mediante TCP/IP:
+
+1. Connetti il dispositivo alla stessa rete Wi-Fi del tuo computer.
+2. Trova l'indirizzo IP del tuo dispositivo in Impostazioni → Informazioni sul telefono → Stato, oppure   eseguendo questo comando:
+
+    ```bash
+    adb shell ip route | awk '{print $9}'
+    ```
+
+3. Abilita adb via TCP/IP sul tuo dispositivo: `adb tcpip 5555`.
+4. Scollega il tuo dispositivo.
+5. Connetti il tuo dispositivo: `adb connect IP_DISPOSITVO:5555` _(rimpiazza `IP_DISPOSITIVO`)_.
+6. Esegui `scrcpy` come al solito.
+
+Potrebbe essere utile diminuire il bit-rate e la definizione
+
+```bash
+scrcpy --bit-rate 2M --max-size 800
+scrcpy -b2M -m800  # versione breve
+```
+
+[connect]: https://developer.android.com/studio/command-line/adb.html#wireless
+
+
+#### Multi dispositivo
+
+Se in `adb devices` sono listati più dispositivi, è necessario specificare il _seriale_:
+
+```bash
+scrcpy --serial 0123456789abcdef
+scrcpy -s 0123456789abcdef  # versione breve
+```
+
+Se il dispositivo è collegato mediante TCP/IP:
+
+```bash
+scrcpy --serial 192.168.0.1:5555
+scrcpy -s 192.168.0.1:5555  # versione breve
+```
+
+Puoi avviare più istanze di _scrcpy_ per diversi dispositivi.
+
+
+#### Avvio automativo alla connessione del dispositivo
+
+Potresti usare [AutoAdb]:
+
+```bash
+autoadb scrcpy -s '{}'
+```
+
+[AutoAdb]: https://github.com/rom1v/autoadb
+
+#### Tunnel SSH
+
+Per connettersi a un dispositivo remoto è possibile collegare un client `adb` locale ad un server `adb` remoto (assunto che entrambi stiano usando la stessa versione del protocollo _adb_):
+
+```bash
+adb kill-server    # termina il server adb locale su 5037
+ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 your_remote_computer
+# tieni questo aperto
+```
+
+Da un altro terminale:
+
+```bash
+scrcpy
+```
+
+Per evitare l'abilitazione dell'apertura porte remota potresti invece forzare una "forward connection" (notare il `-L` invece di `-R`)
+
+```bash
+adb kill-server    # termina il server adb locale su 5037
+ssh -CN -L5037:localhost:5037 -L27183:localhost:27183 your_remote_computer
+# tieni questo aperto
+```
+
+Da un altro terminale:
+
+```bash
+scrcpy --force-adb-forward
+```
+
+
+Come per le connessioni wireless potrebbe essere utile ridurre la qualità:
+
+```
+scrcpy -b2M -m800 --max-fps 15
+```
+
+### Configurazione della finestra
+
+#### Titolo
+
+Il titolo della finestra è il modello del dispositivo per impostazione predefinita. Esso può essere cambiato:
+
+```bash
+scrcpy --window-title 'My device'
+```
+
+#### Posizione e dimensione
+
+La posizione e la dimensione iniziale della finestra può essere specificata:
+
+```bash
+scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
+```
+
+#### Senza bordi
+
+Per disabilitare le decorazioni della finestra:
+
+```bash
+scrcpy --window-borderless
+```
+
+#### Sempre in primo piano
+
+Per tenere scrcpy sempre in primo piano:
+
+```bash
+scrcpy --always-on-top
+```
+
+#### Schermo intero
+
+L'app può essere avviata direttamente a schermo intero:
+
+```bash
+scrcpy --fullscreen
+scrcpy -f  # versione breve
+```
+
+Lo schermo intero può anche essere attivato/disattivato con <kbd>MOD</kbd>+<kbd>f</kbd>.
+
+#### Rotazione
+
+La finestra può essere ruotata:
+
+```bash
+scrcpy --rotation 1
+```
+
+I valori possibili sono:
+ - `0`: nessuna rotazione
+ - `1`: 90 gradi antiorari
+ - `2`: 180 gradi
+ - `3`: 90 gradi orari
+
+La rotazione può anche essere cambiata dinamicamente con <kbd>MOD</kbd>+<kbd>←</kbd>
+_(sinistra)_ e <kbd>MOD</kbd>+<kbd>→</kbd> _(destra)_.
+
+Notare che _scrcpy_ gestisce 3 diversi tipi di rotazione:
+ - <kbd>MOD</kbd>+<kbd>r</kbd> richiede al dispositvo di cambiare tra orientamento verticale (portrait) e orizzontale (landscape) (l'app in uso potrebbe rifiutarsi se non supporta l'orientamento richiesto).
+ - [`--lock-video-orientation`](#blocca-orientamento-del-video) cambia l'orientamento della trasmissione (l'orientamento del video inviato dal dispositivo al computer). Questo influenza la registrazione.
+ - `--rotation` (o <kbd>MOD</kbd>+<kbd>←</kbd>/<kbd>MOD</kbd>+<kbd>→</kbd>) ruota solo il contenuto della finestra. Questo influenza solo la visualizzazione, non la registrazione.
+
+
+### Altre opzioni di trasmissione
+
+#### "Sola lettura"
+
+Per disabilitare i controlli (tutto ciò che può interagire col dispositivo: tasti di input, eventi del mouse, trascina e rilascia (drag&drop) file):
+
+```bash
+scrcpy --no-control
+scrcpy -n
+```
+
+#### Schermo
+
+Se sono disponibili più schermi, è possibile selezionare lo schermo da trasmettere:
+
+```bash
+scrcpy --display 1
+```
+
+La lista degli id schermo può essere ricavata da:
+
+```bash
+adb shell dumpsys display   # cerca "mDisplayId=" nell'output
+```
+
+Lo schermo secondario potrebbe essere possibile controllarlo solo se il dispositivo esegue almeno Android 10 (in caso contrario è trasmesso in modalità sola lettura).
+
+
+#### Mantenere sbloccato
+
+Per evitare che il dispositivo si blocchi dopo un po' che il dispositivo è collegato:
+
+```bash
+scrcpy --stay-awake
+scrcpy -w
+```
+
+Lo stato iniziale è ripristinato quando scrcpy viene chiuso.
+
+
+#### Spegnere lo schermo
+
+È possibile spegnere lo schermo del dispositivo durante la trasmissione con un'opzione da riga di comando:
+
+```bash
+scrcpy --turn-screen-off
+scrcpy -S
+```
+
+Oppure premendo <kbd>MOD</kbd>+<kbd>o</kbd> in qualsiasi momento.
+
+Per riaccenderlo premere <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>o</kbd>.
+
+In Android il pulsante `POWER` (tasto di accensione) accende sempre lo schermo. Per comodità, se `POWER` è inviato via scrcpy (con click destro o con <kbd>MOD</kbd>+<kbd>p</kbd>), si forza il dispositivo a spegnere lo schermo dopo un piccolo ritardo (appena possibile).
+Il pulsante fisico `POWER` continuerà ad accendere lo schermo normalmente.
+
+Può anche essere utile evitare il blocco del dispositivo:
+
+```bash
+scrcpy --turn-screen-off --stay-awake
+scrcpy -Sw
+```
+
+
+#### Mostrare i tocchi
+
+Per le presentazioni può essere utile mostrare i tocchi fisici (sul dispositivo fisico).
+
+Android fornisce questa funzionalità nelle _Opzioni sviluppatore_.
+
+_Scrcpy_ fornisce un'opzione per abilitare questa funzionalità all'avvio e ripristinare il valore iniziale alla chiusura:
+
+```bash
+scrcpy --show-touches
+scrcpy -t
+```
+
+Notare che mostra solo i tocchi _fisici_ (con le dita sul dispositivo).
+
+
+#### Disabilitare il salvaschermo
+
+In maniera predefinita scrcpy non previene l'attivazione del salvaschermo del computer.
+
+Per disabilitarlo:
+
+```bash
+scrcpy --disable-screensaver
+```
+
+
+### Input di controlli
+
+#### Rotazione dello schermo del dispostivo
+
+Premere <kbd>MOD</kbd>+<kbd>r</kbd> per cambiare tra le modalità verticale (portrait) e orizzontale (landscape).
+
+Notare che la rotazione avviene solo se l'applicazione in primo piano supporta l'orientamento richiesto.
+
+#### Copia-incolla
+
+Quando gli appunti di Android cambiano, essi vengono automaticamente sincronizzati con gli appunti del computer.
+
+Qualsiasi scorciatoia <kbd>Ctrl</kbd> viene inoltrata al dispositivo. In particolare:
+ - <kbd>Ctrl</kbd>+<kbd>c</kbd> copia
+ - <kbd>Ctrl</kbd>+<kbd>x</kbd> taglia
+ - <kbd>Ctrl</kbd>+<kbd>v</kbd> incolla (dopo la sincronizzazione degli appunti da computer a dispositivo)
+
+Questo solitamente funziona nella maniera più comune.
+
+Il comportamento reale, però, dipende dall'applicazione attiva. Per esempio _Termux_ invia SIGINT con <kbd>Ctrl</kbd>+<kbd>c</kbd>, e _K-9 Mail_ compone un nuovo messaggio.
+
+Per copiare, tagliare e incollare in questi casi (ma è solo supportato in Android >= 7):
+ - <kbd>MOD</kbd>+<kbd>c</kbd> inietta `COPY`
+ - <kbd>MOD</kbd>+<kbd>x</kbd> inietta `CUT`
+ - <kbd>MOD</kbd>+<kbd>v</kbd> inietta `PASTE` (dopo la sincronizzazione degli appunti da computer a dispositivo)
+
+In aggiunta, <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd> permette l'iniezione del testo degli appunti del computer come una sequenza di eventi pressione dei tasti. Questo è utile quando il componente non accetta l'incollaggio di testo (per esempio in _Termux_), ma questo può rompere il contenuto non ASCII.
+
+**AVVISO:** Incollare gli appunti del computer nel dispositivo (sia con <kbd>Ctrl</kbd>+<kbd>v</kbd> che con <kbd>MOD</kbd>+<kbd>v</kbd>) copia il contenuto negli appunti del dispositivo. Come conseguenza, qualsiasi applicazione Android potrebbe leggere il suo contenuto. Dovresti evitare di incollare contenuti sensibili (come password) in questa maniera.
+
+Alcuni dispositivi non si comportano come aspettato quando si modificano gli appunti del dispositivo a livello di codice. L'opzione `--legacy-paste` è fornita per cambiare il comportamento di <kbd>Ctrl</kbd>+<kbd>v</kbd> and <kbd>MOD</kbd>+<kbd>v</kbd> in modo tale che anch'essi iniettino il testo gli appunti del computer come una sequenza di eventi pressione dei tasti (nella stessa maniera di <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd>).
+
+#### Pizzica per zoomare (pinch-to-zoom)
+
+Per simulare il "pizzica per zoomare": <kbd>Ctrl</kbd>+_click e trascina_.
+
+Più precisamente, tieni premuto <kbd>Ctrl</kbd> mentre premi il pulsante sinistro. Finchè il pulsante non sarà rilasciato, tutti i movimenti del mouse ridimensioneranno e ruoteranno il contenuto (se supportato dall'applicazione) relativamente al centro dello schermo.
+
+Concretamente scrcpy genera degli eventi di tocco addizionali di un "dito virtuale" nella posizione simmetricamente opposta rispetto al centro dello schermo.
+
+
+#### Preferenze di iniezione del testo
+
+Ci sono due tipi di [eventi][textevents] generati quando si scrive testo:
+ - _eventi di pressione_, segnalano che tasto è stato premuto o rilasciato;
+ - _eventi di testo_, segnalano che del testo è stato inserito.
+
+In maniera predefinita le lettere sono "iniettate" usando gli eventi di pressione, in maniera tale che la tastiera si comporti come aspettato nei giochi (come accade solitamente per i tasti WASD).
+
+Questo, però, può [causare problemi][prefertext]. Se incontri un problema del genere, puoi evitarlo con:
+
+```bash
+scrcpy --prefer-text
+```
+
+(ma questo romperà il normale funzionamento della tastiera nei giochi)
+
+[textevents]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-text-input
+[prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343
+
+
+#### Ripetizione di tasti
+
+In maniera predefinita tenere premuto un tasto genera una ripetizione degli eventi di pressione di tale tasto. Questo può creare problemi di performance in alcuni giochi, dove questi eventi sono inutilizzati.
+
+Per prevenire l'inoltro ripetuto degli eventi di pressione:
+
+```bash
+scrcpy --no-key-repeat
+```
+
+#### Click destro e click centrale
+
+In maniera predefinita, click destro aziona BACK (indietro) e il click centrale aziona HOME. Per disabilitare queste scorciatoie e, invece, inviare i click al dispositivo:
+
+```bash
+scrcpy --forward-all-clicks
+```
+
+
+### Rilascio di file
+
+#### Installare APK
+
+Per installare un APK, trascina e rilascia un file APK (finisce con `.apk`) nella finestra di _scrcpy_.
+
+Non c'è alcuna risposta visiva, un log è stampato nella console.
+
+
+#### Trasferimento di file verso il dispositivo
+
+Per trasferire un file in `/sdcard/Download` del dispositivo trascina e rilascia un file (non APK) nella finestra di _scrcpy_.
+
+Non c'è alcuna risposta visiva, un log è stampato nella console.
+
+La cartella di destinazione può essere cambiata all'avvio:
+
+```bash
+scrcpy --push-target=/sdcard/Movies/
+```
+
+
+### Inoltro dell'audio
+
+L'audio non è inoltrato da _scrcpy_. Usa [sndcpy].
+
+Vedi anche la [issue #14].
+
+[sndcpy]: https://github.com/rom1v/sndcpy
+[issue #14]: https://github.com/Genymobile/scrcpy/issues/14
+
+
+## Scociatoie
+
+Nella lista seguente, <kbd>MOD</kbd> è il modificatore delle scorciatoie. In maniera predefinita è <kbd>Alt</kbd> (sinistro) o <kbd>Super</kbd> (sinistro).
+
+Può essere cambiato usando `--shortcut-mod`. I tasti possibili sono `lctrl`, `rctrl`, `lalt`, `ralt`, `lsuper` and `rsuper` (`l` significa sinistro e `r` significa destro). Per esempio:
+
+```bash
+# usa ctrl destro per le scorciatoie
+scrcpy --shortcut-mod=rctrl
+
+# use sia "ctrl sinistro"+"alt sinistro" che "super sinistro" per le scorciatoie
+scrcpy --shortcut-mod=lctrl+lalt,lsuper
+```
+
+_<kbd>[Super]</kbd> è il pulsante <kbd>Windows</kbd> o <kbd>Cmd</kbd>._
+
+[Super]: https://it.wikipedia.org/wiki/Tasto_Windows
+<!-- https://en.wikipedia.org/wiki/Super_key_(keyboard_button) è la pagina originale di Wikipedia inglese, l'ho sostituita con una simile in quello italiano -->

+_³4° e 5° pulsante del mouse, se il tuo mouse ne dispone._  
+_⁴Solo in Android >= 7._
+
+Le scorciatoie con pulsanti ripetuti sono eseguite rilasciando e premendo il pulsante una seconda volta. Per esempio, per eseguire "Espandi il pannello delle impostazioni":
+
+1. Premi e tieni premuto <kbd>MOD</kbd>.
+2. Poi premi due volte <kbd>n</kbd>.
+3. Infine rilascia <kbd>MOD</kbd>.
+
+Tutte le scorciatoie <kbd>Ctrl</kbd>+_tasto_ sono inoltrate al dispositivo, così sono gestite dall'applicazione attiva.
+
+## Path personalizzati
+
+Per utilizzare dei binari _adb_ specifici, configura il suo path nella variabile d'ambente `ADB`:
+
+```bash
+ADB=/percorso/per/adb scrcpy
+```
+
+Per sovrascrivere il percorso del file `scrcpy-server`, configura il percorso in `SCRCPY_SERVER_PATH`.
+
+## Perchè _scrcpy_?
+
+Un collega mi ha sfidato a trovare un nome tanto impronunciabile quanto [gnirehtet].
+
+[`strcpy`] copia una **str**ing (stringa); `scrcpy` copia uno **scr**een (schermo).

+
+## 実行
+
+Androidデバイスを接続し、実行:
+
+```bash
+scrcpy
+```
+
+次のコマンドでリストされるコマンドライン引数も受け付けます:
+
+```bash
+scrcpy --help
+```
+
+## 機能
+
+### キャプチャ構成
+
+#### サイズ削減
+
+Androidデバイスを低解像度でミラーリングする場合、パフォーマンス向上に便利な場合があります。
+
+幅と高さをある値(例：1024)に制限するには:
+
+```bash
+scrcpy --max-size 1024
+scrcpy -m 1024  # 短縮版
+```
+
+一方のサイズはデバイスのアスペクト比が維持されるように計算されます。この方法では、1920x1080のデバイスでは1024x576にミラーリングされます。
+
+
+#### ビットレート変更
+
+ビットレートの初期値は8Mbpsです。ビットレートを変更するには(例:2Mbpsに変更):
+
+```bash
+scrcpy --bit-rate 2M
+scrcpy -b 2M  # 短縮版
+```
+
+#### フレームレート制限
+
+キャプチャするフレームレートを制限できます:
+
+```bash
+scrcpy --max-fps 15
+```
+
+この機能はAndroid 10からオフィシャルサポートとなっていますが、以前のバージョンでも動作する可能性があります。
+
+#### トリミング
+
+デバイスの画面は、画面の一部のみをミラーリングするようにトリミングできます。
+
+これは、例えばOculus Goの片方の目をミラーリングする場合に便利です。:
+
+```bash
+scrcpy --crop 1224:1440:0:0   # オフセット位置(0,0)で1224x1440
+```
+
+もし`--max-size`も指定されている場合、トリミング後にサイズ変更が適用されます。
+
+#### ビデオの向きをロックする
+
+ミラーリングの向きをロックするには:
+
+```bash
+scrcpy --lock-video-orientation     # 現在の向き
+scrcpy --lock-video-orientation=0   # 自然な向き
+scrcpy --lock-video-orientation=1   # 90°反時計回り
+scrcpy --lock-video-orientation=2   # 180°
+scrcpy --lock-video-orientation=3   # 90°時計回り
+```
+
+この設定は録画の向きに影響します。
+
+[ウィンドウは独立して回転することもできます](#回転)。
+
+
+#### エンコーダ
+
+いくつかのデバイスでは一つ以上のエンコーダを持ちます。それらのいくつかは、問題やクラッシュを引き起こします。別のエンコーダを選択することが可能です:
+
+
+```bash
+scrcpy --encoder OMX.qcom.video.encoder.avc
+```
+
+利用可能なエンコーダをリストするために、無効なエンコーダ名を渡すことができます。エラー表示で利用可能なエンコーダを提供します。
+
+```bash
+scrcpy --encoder _
+```
+
+### キャプチャ
+
+#### 録画
+
+ミラーリング中に画面の録画をすることが可能です:
+
+```bash
+scrcpy --record file.mp4
+scrcpy -r file.mkv
+```
+
+録画中にミラーリングを無効にするには:
+
+```bash
+scrcpy --no-display --record file.mp4
+scrcpy -Nr file.mkv
+# Ctrl+Cで録画を中断する
+```
+
+"スキップされたフレーム"は(パフォーマンス上の理由で)リアルタイムで表示されなくても録画されます。
+
+フレームはデバイス上で _タイムスタンプされる_ ため [パケット遅延のバリエーション] は録画されたファイルに影響を与えません。
+
+[パケット遅延のバリエーション]: https://en.wikipedia.org/wiki/Packet_delay_variation
+
+#### v4l2loopback
+
+Linuxでは、ビデオストリームをv4l2ループバックデバイスに送信することができます。
+v4l2loopbackのデバイスにビデオストリームを送信することで、Androidデバイスをウェブカメラのようにv4l2対応ツールで開くこともできます。
+
+`v4l2loopback` モジュールのインストールが必要です。
+
+```bash
+sudo apt install v4l2loopback-dkms
+```
+
+v4l2デバイスを作成する。
+
+```bash
+sudo modprobe v4l2loopback
+```
+
+これにより、新しいビデオデバイスが `/dev/videoN` に作成されます。（`N` は整数）
+(複数のデバイスや特定のIDのデバイスを作成するために、より多くの[オプション](https://github.com/umlaeute/v4l2loopback#options)が利用可能です。
+多くの[オプション]()が利用可能で複数のデバイスや特定のIDのデバイスを作成できます。
+
+
+有効なデバイスを一覧表示する:
+
+```bash
+# v4l-utilsパッケージが必要
+v4l2-ctl --list-devices
+
+# シンプルですが十分これで確認できます
+ls /dev/video*
+```
+
+v4l2シンクを使用してscrcpyを起動する。
+
+```bash
+scrcpy --v4l2-sink=/dev/videoN
+scrcpy --v4l2-sink=/dev/videoN --no-display  # ミラーリングウィンドウを無効化する
+scrcpy --v4l2-sink=/dev/videoN -N            # 短縮版
+```
+
+(`N` をデバイス ID に置き換えて、`ls /dev/video*` で確認してください)
+有効にすると、v4l2対応のツールでビデオストリームを開けます。
+
+```bash
+ffplay -i /dev/videoN
+vlc v4l2:///dev/videoN   # VLCではバッファリングの遅延が発生する場合があります
+```
+
+例えばですが [OBS]の中にこの映像を取り込めことができます。
+
+[OBS]: https://obsproject.com/
+
+
+#### Buffering
+
+バッファリングを追加することも可能です。これによりレイテンシーは増加しますが、ジッターは減少します。（参照
+[#2464])
+
+[#2464]: https://github.com/Genymobile/scrcpy/issues/2464
+
+このオプションでディスプレイバッファリングを設定できます。
+
+```bash
+scrcpy --display-buffer=50  # ディスプレイに50msのバッファリングを追加する
+```
+
+V4L2の場合はこちらのオプションで設定できます。
+
+```bash
+scrcpy --v4l2-buffer=500    # add 500 ms buffering for v4l2 sink
+```
+
+### 接続
+
+#### ワイヤレス
+
+_Scrcpy_ はデバイスとの通信に`adb`を使用します。そして`adb`はTCP/IPを介しデバイスに[接続]することができます:
+
+1. あなたのコンピュータと同じWi-Fiに接続します。
+2. あなたのIPアドレスを取得します。設定 → 端末情報 → ステータス情報、もしくは、このコマンドを実行します:
+
+    ```bash
+    adb shell ip route | awk '{print $9}'
+    ```
+
+3. あなたのデバイスでTCP/IPを介したadbを有効にします: `adb tcpip 5555`
+4. あなたのデバイスの接続を外します。
+5. あなたのデバイスに接続します:
+ `adb connect DEVICE_IP:5555` _(`DEVICE_IP`は置き換える)_
+6. 通常通り`scrcpy`を実行します。
+
+この方法はビットレートと解像度を減らすのにおそらく有用です:
+
+```bash
+scrcpy --bit-rate 2M --max-size 800
+scrcpy -b2M -m800  # 短縮版
+```
+
+[接続]: https://developer.android.com/studio/command-line/adb.html#wireless
+
+
+#### マルチデバイス
+
+もし`adb devices`でいくつかのデバイスがリストされる場合、 _シリアルナンバー_ を指定する必要があります:
+
+```bash
+scrcpy --serial 0123456789abcdef
+scrcpy -s 0123456789abcdef  # 短縮版
+```
+
+デバイスがTCP/IPを介して接続されている場合:
+
+```bash
+scrcpy --serial 192.168.0.1:5555
+scrcpy -s 192.168.0.1:5555  # 短縮版
+```
+
+複数のデバイスに対して、複数の _scrcpy_ インスタンスを開始することができます。
+
+#### デバイス接続での自動起動
+
+[AutoAdb]を使用可能です:
+
+```bash
+autoadb scrcpy -s '{}'
+```
+
+[AutoAdb]: https://github.com/rom1v/autoadb
+
+#### SSHトンネル
+
+リモートデバイスに接続するため、ローカル`adb`クライアントからリモート`adb`サーバーへ接続することが可能です(同じバージョンの _adb_ プロトコルを使用している場合):
+
+```bash
+adb kill-server    # 5037ポートのローカルadbサーバーを終了する
+ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 your_remote_computer
+# オープンしたままにする
+```
+
+他の端末から:
+
+```bash
+scrcpy
+```
+
+リモートポート転送の有効化を回避するためには、代わりに転送接続を強制することができます(`-R`の代わりに`-L`を使用することに注意):
+
+```bash
+adb kill-server    # 5037ポートのローカルadbサーバーを終了する
+ssh -CN -L5037:localhost:5037 -L27183:localhost:27183 your_remote_computer
+# オープンしたままにする
+```
+
+他の端末から:
+
+```bash
+scrcpy --force-adb-forward
+```
+
+
+ワイヤレス接続と同様に、クオリティを下げると便利な場合があります:
+
+```
+scrcpy -b2M -m800 --max-fps 15
+```
+
+### ウィンドウ構成
+
+#### タイトル
+
+ウィンドウのタイトルはデバイスモデルが初期値です。これは変更できます:
+
+```bash
+scrcpy --window-title 'My device'
+```
+
+#### 位置とサイズ
+
+ウィンドウの位置とサイズの初期値を指定できます:
+
+```bash
+scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
+```
+
+#### ボーダーレス
+
+ウィンドウの装飾を無効化するには:
+
+```bash
+scrcpy --window-borderless
+```
+
+#### 常に画面のトップ
+
+scrcpyの画面を常にトップにするには:
+
+```bash
+scrcpy --always-on-top
+```
+
+#### フルスクリーン
+
+アプリケーションを直接フルスクリーンで開始できます:
+
+```bash
+scrcpy --fullscreen
+scrcpy -f  # 短縮版
+```
+
+フルスクリーンは、次のコマンドで動的に切り替えることができます <kbd>MOD</kbd>+<kbd>f</kbd>
+
+
+#### 回転
+
+ウィンドウは回転することができます:
+
+```bash
+scrcpy --rotation 1
+```
+
+設定可能な値:
+ - `0`: 回転なし
+ - `1`: 90° 反時計回り
+ - `2`: 180°
+ - `3`: 90° 時計回り
+
+回転は次のコマンドで動的に変更することができます。 <kbd>MOD</kbd>+<kbd>←</kbd>_(左)_ 、 <kbd>MOD</kbd>+<kbd>→</kbd>_(右)_
+
+_scrcpy_ は3つの回転を管理することに注意:
+ - <kbd>MOD</kbd>+<kbd>r</kbd>はデバイスに縦向きと横向きの切り替えを要求する(現在実行中のアプリで要求している向きをサポートしていない場合、拒否することがある)
+ - [`--lock-video-orientation`](#ビデオの向きをロックする)は、ミラーリングする向きを変更する(デバイスからPCへ送信される向き)。録画に影響します。
+ - `--rotation` (もしくは<kbd>MOD</kbd>+<kbd>←</kbd>/<kbd>MOD</kbd>+<kbd>→</kbd>)は、ウィンドウのコンテンツのみを回転します。これは表示にのみに影響し、録画には影響しません。
+
+### 他のミラーリングオプション
+
+#### Read-only　リードオンリー
+
+制御を無効にするには(デバイスと対話する全てのもの:入力キー、マウスイベント、ファイルのドラッグ&ドロップ):
+
+```bash
+scrcpy --no-control
+scrcpy -n
+```
+
+#### ディスプレイ
+
+いくつか利用可能なディスプレイがある場合、ミラーリングするディスプレイを選択できます:
+
+```bash
+scrcpy --display 1
+```
+
+ディスプレイIDのリストは次の方法で取得できます:
+
+```
+adb shell dumpsys display   # search "mDisplayId=" in the output
+```
+
+セカンダリディスプレイは、デバイスが少なくともAndroid 10の場合にコントロール可能です。(それ以外ではリードオンリーでミラーリングされます)
+
+
+#### 起動状態にする
+
+デバイス接続時、少し遅れてからデバイスのスリープを防ぐには:
+
+```bash
+scrcpy --stay-awake
+scrcpy -w
+```
+
+scrcpyが閉じられた時、初期状態に復元されます。
+
+#### 画面OFF
+
+コマンドラインオプションを使用することで、ミラーリングの開始時にデバイスの画面をOFFにすることができます:
+
+```bash
+scrcpy --turn-screen-off
+scrcpy -S
+```
+
+もしくは、<kbd>MOD</kbd>+<kbd>o</kbd>を押すことでいつでもできます。
+
+元に戻すには、<kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>o</kbd>を押します。
+
+Androidでは、`POWER`ボタンはいつでも画面を表示します。便宜上、`POWER`がscrcpyを介して(右クリックもしくは<kbd>MOD</kbd>+<kbd>p</kbd>を介して)送信される場合、(ベストエフォートベースで)少し遅れて、強制的に画面を非表示にします。ただし、物理的な`POWER`ボタンを押した場合は、画面は表示されます。
+
+このオプションはデバイスがスリープしないようにすることにも役立ちます:
+
+```bash
+scrcpy --turn-screen-off --stay-awake
+scrcpy -Sw
+```
+
+
+#### タッチを表示
+
+プレゼンテーションの場合(物理デバイス上で)物理的なタッチを表示すると便利な場合があります。
+
+Androidはこの機能を _開発者オプション_ で提供します。
+
+_Scrcpy_　は開始時にこの機能を有効にし、終了時に初期値を復元するオプションを提供します:
+
+```bash
+scrcpy --show-touches
+scrcpy -t
+```
+
+(デバイス上で指を使った) _物理的な_ タッチのみ表示されることに注意してください。
+
+
+#### スクリーンセーバー無効
+
+初期状態では、scrcpyはコンピュータ上でスクリーンセーバーが実行される事を妨げません。
+
+これを無効にするには:
+
+```bash
+scrcpy --disable-screensaver
+```
+
+
+### 入力制御
+
+#### デバイス画面の回転
+
+<kbd>MOD</kbd>+<kbd>r</kbd>を押すことで、縦向きと横向きを切り替えます。
+
+フォアグラウンドのアプリケーションが要求された向きをサポートしている場合のみ回転することに注意してください。
+
+#### コピー-ペースト
+
+Androidのクリップボードが変更される度に、コンピュータのクリップボードに自動的に同期されます。
+
+<kbd>Ctrl</kbd>のショートカットは全てデバイスに転送されます。特に:
+ - <kbd>Ctrl</kbd>+<kbd>c</kbd> 通常はコピーします
+ - <kbd>Ctrl</kbd>+<kbd>x</kbd> 通常はカットします
+ - <kbd>Ctrl</kbd>+<kbd>v</kbd> 通常はペーストします(コンピュータとデバイスのクリップボードが同期された後)
+
+通常は期待通りに動作します。
+
+しかしながら、実際の動作はアクティブなアプリケーションに依存します。例えば、_Termux_ は代わりに<kbd>Ctrl</kbd>+<kbd>c</kbd>でSIGINTを送信します、そして、_K-9 Mail_ は新しいメッセージを作成します。
+
+このようなケースでコピー、カットそしてペーストをするには(Android 7以上でのサポートのみですが):
+ - <kbd>MOD</kbd>+<kbd>c</kbd> `COPY`を挿入
+ - <kbd>MOD</kbd>+<kbd>x</kbd> `CUT`を挿入
+ - <kbd>MOD</kbd>+<kbd>v</kbd> `PASTE`を挿入(コンピュータとデバイスのクリップボードが同期された後)
+
+加えて、<kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd>はコンピュータのクリップボードテキストにキーイベントのシーケンスとして挿入することを許可します。これはコンポーネントがテキストのペーストを許可しない場合(例えば _Termux_)に有用ですが、非ASCIIコンテンツを壊す可能性があります。
+
+**警告:** デバイスにコンピュータのクリップボードを(<kbd>Ctrl</kbd>+<kbd>v</kbd>または<kbd>MOD</kbd>+<kbd>v</kbd>を介して)ペーストすることは、デバイスのクリップボードにコンテンツをコピーします。結果としてどのAndoridアプリケーションもそのコンテンツを読み取ることができます。機密性の高いコンテンツ(例えばパスワードなど)をこの方法でペーストすることは避けてください。
+
+プログラムでデバイスのクリップボードを設定した場合、一部のデバイスは期待どおりに動作しません。`--legacy-paste`オプションは、コンピュータのクリップボードテキストをキーイベントのシーケンスとして挿入するため(<kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd>と同じ方法)、<kbd>Ctrl</kbd>+<kbd>v</kbd>と<kbd>MOD</kbd>+<kbd>v</kbd>の動作の変更を提供します。
+
+#### ピンチしてズームする
+
+"ピンチしてズームする"をシミュレートするには: <kbd>Ctrl</kbd>+_クリック&移動_
+
+より正確にするには、左クリックボタンを押している間、<kbd>Ctrl</kbd>を押したままにします。左クリックボタンを離すまで、全てのマウスの動きは、(アプリでサポートされている場合)画面の中心を基準として、コンテンツを拡大縮小および回転します。
+
+具体的には、scrcpyは画面の中央を反転した位置にある"バーチャルフィンガー"から追加のタッチイベントを生成します。
+
+
+#### テキストインジェクション環境設定
+
+テキストをタイプした時に生成される2種類の[イベント][textevents]があります:
+ - _key events_　はキーを押したときと離したことを通知します。
+ - _text events_　はテキストが入力されたことを通知します。
+
+初期状態で、文字はキーイベントで挿入されるため、キーボードはゲームで期待通りに動作します(通常はWASDキー)。
+
+しかし、これは[問題を引き起こす][prefertext]かもしれません。もしこのような問題が発生した場合は、この方法で回避できます:
+
+```bash
+scrcpy --prefer-text
+```
+
+(しかしこの方法はゲームのキーボードの動作を壊します)
+
+[textevents]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-text-input
+[prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343
+
+
+#### キーの繰り返し
+
+初期状態では、キーの押しっぱなしは繰り返しのキーイベントを生成します。これらのイベントが使われない場合でも、この方法は一部のゲームでパフォーマンスの問題を引き起す可能性があります。
+
+繰り返しのキーイベントの転送を回避するためには:
+
+```bash
+scrcpy --no-key-repeat
+```
+
+
+#### 右クリックと真ん中クリック
+
+初期状態では、右クリックはバックの動作(もしくはパワーオン)を起こし、真ん中クリックではホーム画面へ戻ります。このショートカットを無効にし、代わりにデバイスへクリックを転送するには:
+
+```bash
+scrcpy --forward-all-clicks
+```
+
+
+### ファイルのドロップ
+
+#### APKのインストール
+
+APKをインストールするには、(`.apk`で終わる)APKファイルを _scrcpy_ の画面にドラッグ&ドロップします。
+
+見た目のフィードバックはありません。コンソールにログが出力されます。
+
+
+#### デバイスにファイルを送る
+
+デバイスの`/sdcard/Download`ディレクトリにファイルを送るには、(APKではない)ファイルを _scrcpy_ の画面にドラッグ&ドロップします。
+
+見た目のフィードバックはありません。コンソールにログが出力されます。
+
+転送先ディレクトリを起動時に変更することができます:
+
+```bash
+scrcpy --push-target=/sdcard/Movies/
+```
+
+
+### 音声転送
+
+音声は _scrcpy_ では転送されません。[sndcpy]を使用します。
+
+[issue #14]も参照ください。
+
+[sndcpy]: https://github.com/rom1v/sndcpy
+[issue #14]: https://github.com/Genymobile/scrcpy/issues/14
+
+
+## ショートカット
+
+次のリストでは、<kbd>MOD</kbd>でショートカット変更します。初期状態では、(left)<kbd>Alt</kbd>または(left)<kbd>Super</kbd>です。
+
+これは`--shortcut-mod`で変更することができます。可能なキーは`lctrl`、`rctrl`、`lalt`、 `ralt`、 `lsuper`そして`rsuper`です。例えば:
+
+```bash
+# RCtrlをショートカットとして使用します
+scrcpy --shortcut-mod=rctrl
+
+# ショートカットにLCtrl+LAltまたはLSuperのいずれかを使用します
+scrcpy --shortcut-mod=lctrl+lalt,lsuper
+```
+
+_<kbd>[Super]</kbd>は通常<kbd>Windows</kbd>もしくは<kbd>Cmd</kbd>キーです。_
+
+[Super]: https://en.wikipedia.org/wiki/Super_key_(keyboard_button)

+
+[control]: https://github.com/Genymobile/scrcpy/issues/70#issuecomment-373286323
+
+
+## 앱 설치하기
+
+
+### Linux (리눅스)
+
+리눅스 상에서는 보통 [어플을 직접 설치][BUILD] 해야합니다. 어렵지 않으므로 걱정하지 않아도 됩니다.
+
+[BUILD]:https://github.com/Genymobile/scrcpy/blob/master/BUILD.md
+
+[Snap] 패키지가 가능합니다 : [`scrcpy`][snap-link].
+
+[snap-link]: https://snapstats.org/snaps/scrcpy
+
+[snap]: https://en.wikipedia.org/wiki/Snappy_(package_manager)
+
+Arch Linux에서, [AUR] 패키지가 가능합니다 : [`scrcpy`][aur-link].
+
+[AUR]: https://wiki.archlinux.org/index.php/Arch_User_Repository
+[aur-link]: https://aur.archlinux.org/packages/scrcpy/
+
+Gentoo에서 ,[Ebuild] 가 가능합니다 : [`scrcpy/`][ebuild-link].
+
+[Ebuild]: https://wiki.gentoo.org/wiki/Ebuild
+[ebuild-link]: https://github.com/maggu2810/maggu2810-overlay/tree/master/app-mobilephone/scrcpy
+
+
+### Windows (윈도우)
+
+윈도우 상에서, 간단하게 설치하기 위해 종속성이 있는 사전 구축된 아카이브가 제공됩니다 (`adb` 포함) :
+해당 파일은 Readme원본 링크를 통해서 다운로드가 가능합니다.
+ - [README](README.md#windows)
+
+
+[어플을 직접 설치][BUILD] 할 수도 있습니다.
+
+
+### macOS (맥 OS)
+
+이 어플리케이션은 아래 사항을 따라 설치한다면 [Homebrew] 에서도 사용 가능합니다 :
+
+[Homebrew]: https://brew.sh/
+
+```bash
+brew install scrcpy
+```
+
+`PATH` 로부터 접근 가능한 `adb` 가 필요합니다. 아직 설치하지 않았다면 다음을 따라 설치해야 합니다 :
+
+```bash
+brew cask install android-platform-tools
+```
+
+[어플을 직접 설치][BUILD] 할 수도 있습니다.
+
+
+## 실행
+
+안드로이드 디바이스를 연결하고 실행하십시오:
+
+```bash
+scrcpy
+```
+
+다음과 같이 명령창 옵션 기능도 제공합니다.
+
+```bash
+scrcpy --help
+```
+
+## 기능
+
+### 캡쳐 환경 설정
+
+
+### 사이즈 재정의
+
+가끔씩 성능을 향상시키기위해 안드로이드 디바이스를 낮은 해상도에서 미러링하는 것이 유용할 때도 있습니다.
+
+너비와 높이를 제한하기 위해 특정 값으로 지정할 수 있습니다 (e.g. 1024) :
+
+```bash
+scrcpy --max-size 1024
+scrcpy -m 1024  # 축약 버전
+```
+
+이 외의 크기도 디바이스의 가로 세로 비율이 유지된 상태에서 계산됩니다.
+이러한 방식으로 디바이스 상에서 1920×1080 는 모니터 상에서1024×576로 미러링될 것 입니다.
+
+
+### bit-rate 변경
+
+기본 bit-rate 는 8 Mbps입니다. 비디오 bit-rate 를 변경하기 위해선 다음과 같이 입력하십시오 (e.g. 2 Mbps로 변경):
+
+```bash
+scrcpy --bit-rate 2M
+scrcpy -b 2M  # 축약 버전
+```
+
+### 프레임 비율 제한
+
+안드로이드 버전 10이상의 디바이스에서는, 다음의 명령어로 캡쳐 화면의 프레임 비율을 제한할 수 있습니다:
+
+```bash
+scrcpy --max-fps 15
+```
+
+
+### Crop (잘라내기)
+
+디바이스 화면은 화면의 일부만 미러링하기 위해 잘라질 것입니다.
+
+예를 들어, *Oculus Go* 의 한 쪽 눈만 미러링할 때 유용합니다 :
+
+```bash
+scrcpy --crop 1224:1440:0:0   # 1224x1440 at offset (0,0)
+scrcpy -c 1224:1440:0:0       # 축약 버전
+```
+
+만약 `--max-size` 도 지정하는 경우, 잘라낸 다음에 재정의된 크기가 적용될 것입니다.
+
+
+### 화면 녹화
+
+미러링하는 동안 화면 녹화를 할 수 있습니다 :
+
+```bash
+scrcpy --record file.mp4
+scrcpy -r file.mkv
+```
+
+녹화하는 동안 미러링을 멈출 수 있습니다 :
+
+```bash
+scrcpy --no-display --record file.mp4
+scrcpy -Nr file.mkv
+# Ctrl+C 로 녹화를 중단할 수 있습니다.
+# 윈도우 상에서 Ctrl+C 는 정상정으로 종료되지 않을 수 있으므로, 디바이스 연결을 해제하십시오.
+```
+
+"skipped frames" 은 모니터 화면에 보여지지 않았지만 녹화되었습니다 ( 성능 문제로 인해 ). 프레임은 디바이스 상에서 _타임 스탬프 ( 어느 시점에 데이터가 존재했다는 사실을 증명하기 위해 특정 위치에 시각을 표시 )_ 되었으므로, [packet delay
+variation] 은 녹화된 파일에 영향을 끼치지 않습니다.
+
+[packet delay variation]: https://en.wikipedia.org/wiki/Packet_delay_variation
+
+## 연결
+
+### 무선연결
+
+_Scrcpy_ 장치와 정보를 주고받기 위해 `adb` 를 사용합니다.  `adb` 는 TCIP/IP 를 통해 디바이스와 [연결][connect] 할 수 있습니다 :
+
+1. 컴퓨터와 디바이스를 동일한 Wi-Fi 에 연결합니다.
+2. 디바이스의 IP address 를 확인합니다 (설정 → 내 기기 → 상태 / 혹은 인터넷에 '내 IP'검색 시 확인 가능합니다. ).
+3. TCP/IP 를 통해 디바이스에서 adb 를 사용할 수 있게 합니다: `adb tcpip 5555`.
+4. 디바이스 연결을 해제합니다.
+5. adb 를 통해 디바이스에 연결을 합니다\: `adb connect DEVICE_IP:5555` _(`DEVICE_IP` 대신)_.
+6. `scrcpy` 실행합니다.
+
+다음은 bit-rate 와 해상도를 줄이는데 유용합니다 :
+
+```bash
+scrcpy --bit-rate 2M --max-size 800
+scrcpy -b2M -m800  # 축약 버전
+```
+
+[connect]: https://developer.android.com/studio/command-line/adb.html#wireless
+
+
+
+### 여러 디바이스 사용 가능
+
+만약에 여러 디바이스들이 `adb devices` 목록에 표시되었다면, _serial_ 을 명시해야합니다:
+
+```bash
+scrcpy --serial 0123456789abcdef
+scrcpy -s 0123456789abcdef  # 축약 버전
+```
+
+_scrcpy_ 로 여러 디바이스를 연결해 사용할 수 있습니다.
+
+
+#### SSH tunnel
+
+떨어져 있는 디바이스와 연결하기 위해서는, 로컬 `adb` client와 떨어져 있는 `adb` 서버를 연결해야 합니다.  (디바이스와 클라이언트가 동일한 버전의 _adb_ protocol을 사용할 경우에 제공됩니다.):
+
+```bash
+adb kill-server    # 5037의 로컬 local adb server를 중단
+ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 your_remote_computer
+# 실행 유지
+```
+
+다른 터미널에서는 :
+
+```bash
+scrcpy
+```
+
+무선 연결과 동일하게, 화질을 줄이는 것이 나을 수 있습니다:
+
+```
+scrcpy -b2M -m800 --max-fps 15
+```
+
+## Window에서의 배치
+
+### 맞춤형 window 제목
+
+기본적으로, window의 이름은 디바이스의 모델명 입니다.
+다음의 명령어를 통해 변경하세요.
+
+```bash
+scrcpy --window-title 'My device'
+```
+
+
+### 배치와 크기
+
+초기 window창의 배치와 크기는 다음과 같이 설정할 수 있습니다:
+
+```bash
+scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
+```
+
+
+### 경계 없애기
+
+윈도우 장식(경계선 등)을 다음과 같이 제거할 수 있습니다:
+
+```bash
+scrcpy --window-borderless
+```
+
+### 항상 모든 윈도우 위에 실행창 고정
+
+이 어플리케이션의 윈도우 창은 다음의 명령어로 다른 window 위에 디스플레이 할 수 있습니다:
+
+```bash
+scrcpy --always-on-top
+scrcpy -T  # 축약 버전
+```
+
+### 전체 화면
+
+이 어플리케이션은 전체화면으로 바로 시작할 수 있습니다.
+
+```bash
+scrcpy --fullscreen
+scrcpy -f  # short version
+```
+
+전체 화면은  `Ctrl`+`f`키로 끄거나 켤 수 있습니다.
+
+
+## 다른 미러링 옵션
+
+### 읽기 전용(Read-only)
+
+권한을 제한하기 위해서는 (디바이스와 관련된 모든 것: 입력 키, 마우스 이벤트 , 파일의 드래그 앤 드랍(drag&drop)):
+
+```bash
+scrcpy --no-control
+scrcpy -n
+```
+
+### 화면 끄기
+
+미러링을 실행하는 와중에 디바이스의 화면을 끌 수 있게 하기 위해서는
+다음의 커맨드 라인 옵션을(command line option) 입력하세요:
+
+```bash
+scrcpy --turn-screen-off
+scrcpy -S
+```
+
+혹은 `Ctrl`+`o`을 눌러 언제든지 디바이스의 화면을 끌 수 있습니다.
+
+다시 화면을 켜기 위해서는`POWER` (혹은 `Ctrl`+`p`)를 누르세요.
+
+
+### 유효기간이 지난 프레임 제공 (Render expired frames)
+
+디폴트로, 대기시간을 최소화하기 위해 _scrcpy_ 는 항상 마지막으로 디코딩된 프레임을 제공합니다
+과거의 프레임은 하나씩 삭제합니다.
+
+모든 프레임을 강제로 렌더링하기 위해서는 (대기 시간이 증가될 수 있습니다)
+다음의 명령어를 사용하세요:
+
+```bash
+scrcpy --render-expired-frames
+```
+
+
+### 화면에 터치 나타내기
+
+발표를 할 때, 물리적인 기기에 한 물리적 터치를 나타내는 것이 유용할 수 있습니다.
+
+안드로이드 운영체제는 이런 기능을 _Developers options_에서 제공합니다.
+
+_Scrcpy_ 는 이런 기능을 시작할 때와 종료할 때 옵션으로 제공합니다.
+
+```bash
+scrcpy --show-touches
+scrcpy -t
+```
+
+화면에 _물리적인 터치만_ 나타나는 것에 유의하세요 (손가락을 디바이스에 대는 행위).
+
+
+### 입력 제어
+
+#### 복사-붙여넣기
+
+컴퓨터와 디바이스 양방향으로 클립보드를 복사하는 것이 가능합니다:
+
+ - `Ctrl`+`c` 디바이스의 클립보드를 컴퓨터로 복사합니다;
+ - `Ctrl`+`Shift`+`v` 컴퓨터의 클립보드를 디바이스로 복사합니다;
+ - `Ctrl`+`v` 컴퓨터의 클립보드를 text event 로써 _붙여넣습니다_  ( 그러나, ASCII 코드가 아닌 경우 실행되지 않습니다 )
+
+#### 텍스트 삽입 우선 순위
+
+텍스트를 입력할 때 생성되는 두 가지의 [events][textevents] 가 있습니다:
+ - _key events_, 키가 눌려있는 지에 대한 신호;
+ - _text events_, 텍스트가 입력되었는지에 대한 신호.
+
+기본적으로, 글자들은 key event 를 이용해 입력되기 때문에, 키보드는 게임에서처럼 처리합니다 ( 보통 WASD 키에 대해서 ).
+
+그러나 이는 [issues 를 발생][prefertext]시킵니다. 이와 관련된 문제를 접할 경우, 아래와 같이 피할 수 있습니다:
+
+```bash
+scrcpy --prefer-text
+```
+
+( 그러나 이는 게임에서의 처리를 중단할 수 있습니다 )
+
+[textevents]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-text-input
+[prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343
+
+
+### 파일 드랍
+
+### APK 실행하기
+
+APK를 실행하기 위해서는, APK file(파일명이`.apk`로 끝나는 파일)을  드래그하고 _scrcpy_ window에 드랍하세요 (drag and drop)
+
+시각적인 피드백은 없고,log 하나가 콘솔에 출력될 것입니다.
+
+### 디바이스에 파일 push하기
+
+디바이스의`/sdcard/`에 파일을 push하기 위해서는,
+APK파일이 아닌 파일을_scrcpy_ window에 드래그하고 드랍하세요.(drag and drop).
+
+시각적인 피드백은 없고,log 하나가 콘솔에 출력될 것입니다.
+
+해당 디렉토리는 시작할 때 변경이 가능합니다:
+
+```bash
+scrcpy --push-target /sdcard/foo/bar/
+```
+
+### 오디오의 전달
+
+_scrcpy_는 오디오를 직접 전달해주지 않습니다. [USBaudio] (Linux-only)를 사용하세요.
+
+추가적으로 [issue #14]를 참고하세요.

+
+
+## Executar
+
+Conecte um dispositivo Android e execute:
+
+```bash
+scrcpy
+```
+
+Também aceita argumentos de linha de comando, listados por:
+
+```bash
+scrcpy --help
+```
+
+## Funcionalidades
+
+### Configuração de captura
+
+#### Reduzir tamanho
+
+Algumas vezes, é útil espelhar um dispositivo Android em uma resolução menor para
+aumentar a performance.
+
+Para limitar ambos (largura e altura) para algum valor (ex: 1024):
+
+```bash
+scrcpy --max-size 1024
+scrcpy -m 1024  # versão curta
+```
+
+A outra dimensão é calculada para que a proporção do dispositivo seja preservada.
+Dessa forma, um dispositivo de 1920x1080 será espelhado em 1024x576.
+
+
+#### Mudar bit-rate
+
+O bit-rate padrão é 8 Mbps. Para mudar o bit-rate do vídeo (ex: para 2 Mbps):
+
+```bash
+scrcpy --bit-rate 2M
+scrcpy -b 2M  # versão curta
+```
+
+#### Limitar frame rate
+
+O frame rate de captura pode ser limitado:
+
+```bash
+scrcpy --max-fps 15
+```
+
+Isso é oficialmente suportado desde o Android 10, mas pode funcionar em versões anteriores.
+
+#### Cortar
+
+A tela do dispositivo pode ser cortada para espelhar apenas uma parte da tela.
+
+Isso é útil por exemplo, para espelhar apenas um olho do Oculus Go:
+
+```bash
+scrcpy --crop 1224:1440:0:0   # 1224x1440 no deslocamento (0,0)
+```
+
+Se `--max-size` também for especificado, o redimensionamento é aplicado após o corte.
+
+
+#### Travar orientação do vídeo
+
+
+Para travar a orientação do espelhamento:
+
+```bash
+scrcpy --lock-video-orientation     # orientação inicial (Atual)
+scrcpy --lock-video-orientation=0   # orientação natural
+scrcpy --lock-video-orientation=1   # 90° sentido anti-horário
+scrcpy --lock-video-orientation=2   # 180°
+scrcpy --lock-video-orientation=3   # 90° sentido horário
+```
+
+Isso afeta a orientação de gravação.
+
+A [janela também pode ser rotacionada](#rotação) independentemente.
+
+
+#### Encoder
+
+Alguns dispositivos têm mais de um encoder, e alguns deles podem causar problemas ou
+travar. É possível selecionar um encoder diferente:
+
+```bash
+scrcpy --encoder OMX.qcom.video.encoder.avc
+```
+
+Para listar os encoders disponíveis, você pode passar um nome de encoder inválido, o
+erro dará os encoders disponíveis:
+
+```bash
+scrcpy --encoder _
+```
+
+### Captura
+
+#### Gravando
+
+É possível gravar a tela enquanto ocorre o espelhamento:
+
+```bash
+scrcpy --record file.mp4
+scrcpy -r file.mkv
+```
+
+Para desativar o espelhamento durante a gravação:
+
+```bash
+scrcpy --no-display --record file.mp4
+scrcpy -Nr file.mkv
+# interrompa a gravação com Ctrl+C
+```
+
+"Frames pulados" são gravados, mesmo que não sejam exibidos em tempo real (por
+motivos de performance). Frames têm seu _horário carimbado_ no dispositivo, então [variação de atraso nos
+pacotes][packet delay variation] não impacta o arquivo gravado.
+
+[packet delay variation]: https://en.wikipedia.org/wiki/Packet_delay_variation
+
+
+#### v4l2loopback
+
+Em Linux, é possível enviar a transmissão do video para um disposiivo v4l2 loopback, assim
+o dispositivo Android pode ser aberto como uma webcam por qualquer ferramneta capaz de v4l2
+
+The module `v4l2loopback` must be installed:
+
+```bash
+sudo apt install v4l2loopback-dkms
+```
+
+Para criar um dispositivo v4l2:
+
+```bash
+sudo modprobe v4l2loopback
+```
+
+Isso criara um novo dispositivo de vídeo em `/dev/videoN`, onde `N` é uma integer
+(mais [opções](https://github.com/umlaeute/v4l2loopback#options) estão disponiveis
+para criar varios dispositivos ou dispositivos com IDs específicas).
+
+Para listar os dispositivos disponíveis:
+
+```bash
+# requer o pacote v4l-utils
+v4l2-ctl --list-devices
+
+# simples, mas pode ser suficiente
+ls /dev/video*
+```
+
+Para iniciar o scrcpy usando o coletor v4l2 (sink):
+
+```bash
+scrcpy --v4l2-sink=/dev/videoN
+scrcpy --v4l2-sink=/dev/videoN --no-display  # desativa a janela espelhada
+scrcpy --v4l2-sink=/dev/videoN -N            # versão curta
+```
+
+(troque `N` pelo ID do dipositivo, verifique com `ls /dev/video*`)
+
+Uma vez ativado, você pode abrir suas trasmissões de videos com uma ferramenta capaz de v4l2:
+
+```bash
+ffplay -i /dev/videoN
+vlc v4l2:///dev/videoN   # VLC pode adicionar um pouco de atraso de buffering
+```
+
+Por exemplo, você pode capturar o video dentro do [OBS].
+
+[OBS]: https://obsproject.com/
+
+
+#### Buffering
+
+É possivel adicionar buffering. Isso aumenta a latência, mas reduz a tenção (jitter) (veja
+[#2464]).
+
+[#2464]: https://github.com/Genymobile/scrcpy/issues/2464
+
+A opção éta disponivel para buffering de exibição:
+
+```bash
+scrcpy --display-buffer=50  # adiciona 50 ms de buffering para a exibição
+```
+
+e coletor V4L2:
+
+```bash
+scrcpy --v4l2-buffer=500    # adiciona 500 ms de buffering para coletor V4L2
+```
+
+,
+### Conexão
+
+#### Sem fio
+
+_Scrcpy_ usa `adb` para se comunicar com o dispositivo, e `adb` pode [conectar-se][connect] a um
+dispositivo via TCP/IP:
+
+1. Conecte o dispositivo no mesmo Wi-Fi do seu computador.
+2. Pegue o endereço IP do seu dispositivo, em Configurações → Sobre o telefone → Status, ou
+   executando este comando:
+
+    ```bash
+    adb shell ip route | awk '{print $9}'
+    ```
+
+3. Ative o adb via TCP/IP no seu dispositivo: `adb tcpip 5555`.
+4. Desconecte seu dispositivo.
+5. Conecte-se ao seu dispositivo: `adb connect DEVICE_IP:5555` _(substitua `DEVICE_IP`)_.
+6. Execute `scrcpy` como de costume.
+
+Pode ser útil diminuir o bit-rate e a resolução:
+
+```bash
+scrcpy --bit-rate 2M --max-size 800
+scrcpy -b2M -m800  # versão curta
+```
+
+[connect]: https://developer.android.com/studio/command-line/adb.html#wireless
+
+
+#### Múltiplos dispositivos
+
+Se vários dispositivos são listados em `adb devices`, você deve especificar o _serial_:
+
+```bash
+scrcpy --serial 0123456789abcdef
+scrcpy -s 0123456789abcdef  # versão curta
+```
+
+Se o dispositivo está conectado via TCP/IP:
+
+```bash
+scrcpy --serial 192.168.0.1:5555
+scrcpy -s 192.168.0.1:5555  # versão curta
+```
+
+Você pode iniciar várias instâncias do _scrcpy_ para vários dispositivos.
+
+#### Iniciar automaticamente quando dispositivo é conectado
+
+Você pode usar [AutoAdb]:
+
+```bash
+autoadb scrcpy -s '{}'
+```
+
+[AutoAdb]: https://github.com/rom1v/autoadb
+
+#### Túnel SSH
+
+Para conectar-se a um dispositivo remoto, é possível conectar um cliente `adb` local a
+um servidor `adb` remoto (contanto que eles usem a mesma versão do protocolo
+_adb_):
+
+```bash
+adb kill-server    # encerra o servidor adb local em 5037
+ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 your_remote_computer
+# mantenha isso aberto
+```
+
+De outro terminal:
+
+```bash
+scrcpy
+```
+
+Para evitar ativar o encaminhamento de porta remota, você pode forçar uma conexão
+de encaminhamento (note o `-L` em vez de `-R`):
+
+```bash
+adb kill-server    # encerra o servidor adb local em 5037
+ssh -CN -L5037:localhost:5037 -L27183:localhost:27183 your_remote_computer
+# mantenha isso aberto
+```
+
+De outro terminal:
+
+```bash
+scrcpy --force-adb-forward
+```
+
+
+Igual a conexões sem fio, pode ser útil reduzir a qualidade:
+
+```
+scrcpy -b2M -m800 --max-fps 15
+```
+
+### Configuração de janela
+
+#### Título
+
+Por padrão, o título da janela é o modelo do dispositivo. Isso pode ser mudado:
+
+```bash
+scrcpy --window-title 'Meu dispositivo'
+```
+
+#### Posição e tamanho
+
+A posição e tamanho iniciais da janela podem ser especificados:
+
+```bash
+scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
+```
+
+#### Sem bordas
+
+Para desativar decorações de janela:
+
+```bash
+scrcpy --window-borderless
+```
+
+#### Sempre no topo
+
+Para manter a janela do scrcpy sempre no topo:
+
+```bash
+scrcpy --always-on-top
+```
+
+#### Tela cheia
+
+A aplicação pode ser iniciada diretamente em tela cheia:
+
+```bash
+scrcpy --fullscreen
+scrcpy -f  # versão curta
+```
+
+Tela cheia pode ser alternada dinamicamente com <kbd>MOD</kbd>+<kbd>f</kbd>.
+
+#### Rotação
+
+A janela pode ser rotacionada:
+
+```bash
+scrcpy --rotation 1
+```
+
+Valores possíveis são:
+ - `0`: sem rotação
+ - `1`: 90 graus sentido anti-horário
+ - `2`: 180 graus
+ - `3`: 90 graus sentido horário
+
+A rotação também pode ser mudada dinamicamente com <kbd>MOD</kbd>+<kbd>←</kbd>
+_(esquerda)_ e <kbd>MOD</kbd>+<kbd>→</kbd> _(direita)_.
+
+Note que _scrcpy_ controla 3 rotações diferentes:
+ - <kbd>MOD</kbd>+<kbd>r</kbd> requisita ao dispositivo para mudar entre retrato
+   e paisagem (a aplicação em execução pode se recusar, se ela não suporta a
+   orientação requisitada).
+ - [`--lock-video-orientation`](#travar-orientação-do-vídeo) muda a orientação de
+   espelhamento (a orientação do vídeo enviado pelo dispositivo para o
+   computador). Isso afeta a gravação.
+ - `--rotation` (ou <kbd>MOD</kbd>+<kbd>←</kbd>/<kbd>MOD</kbd>+<kbd>→</kbd>)
+   rotaciona apenas o conteúdo da janela. Isso afeta apenas a exibição, não a
+   gravação.
+
+
+### Outras opções de espelhamento
+
+#### Apenas leitura
+
+Para desativar controles (tudo que possa interagir com o dispositivo: teclas de entrada,
+eventos de mouse, arrastar e soltar arquivos):
+
+```bash
+scrcpy --no-control
+scrcpy -n
+```
+
+#### Display
+
+Se vários displays estão disponíveis, é possível selecionar o display para
+espelhar:
+
+```bash
+scrcpy --display 1
+```
+
+A lista de IDs dos displays pode ser obtida por:
+
+```
+adb shell dumpsys display   # busca "mDisplayId=" na saída
+```
+
+O display secundário pode apenas ser controlado se o dispositivo roda pelo menos Android
+10 (caso contrário é espelhado como apenas leitura).
+
+
+#### Permanecer ativo
+
+Para evitar que o dispositivo seja suspenso após um delay quando o dispositivo é conectado:
+
+```bash
+scrcpy --stay-awake
+scrcpy -w
+```
+
+O estado inicial é restaurado quando o scrcpy é fechado.
+
+
+#### Desligar tela
+
+É possível desligar a tela do dispositivo durante o início do espelhamento com uma
+opção de linha de comando:
+
+```bash
+scrcpy --turn-screen-off
+scrcpy -S
+```
+
+Ou apertando <kbd>MOD</kbd>+<kbd>o</kbd> a qualquer momento.
+
+Para ligar novamente, pressione <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>o</kbd>.
+
+No Android, o botão de `POWER` sempre liga a tela. Por conveniência, se
+`POWER` é enviado via scrcpy (via clique-direito ou <kbd>MOD</kbd>+<kbd>p</kbd>), ele
+forçará a desligar a tela após um delay pequeno (numa base de melhor esforço).
+O botão `POWER` físico ainda causará a tela ser ligada.
+
+Também pode ser útil evitar que o dispositivo seja suspenso:
+
+```bash
+scrcpy --turn-screen-off --stay-awake
+scrcpy -Sw
+```
+
+
+#### Mostrar toques
+
+Para apresentações, pode ser útil mostrar toques físicos (no dispositivo
+físico).
+
+Android fornece esta funcionalidade nas _Opções do desenvolvedor_.
+
+_Scrcpy_ fornece esta opção de ativar esta funcionalidade no início e restaurar o
+valor inicial no encerramento:
+
+```bash
+scrcpy --show-touches
+scrcpy -t
+```
+
+Note que isto mostra apenas toques _físicos_ (com o dedo no dispositivo).
+
+
+#### Desativar descanso de tela
+
+Por padrão, scrcpy não evita que o descanso de tela rode no computador.
+
+Para desativá-lo:
+
+```bash
+scrcpy --disable-screensaver
+```
+
+
+### Controle de entrada
+
+#### Rotacionar a tela do dispositivo
+
+Pressione <kbd>MOD</kbd>+<kbd>r</kbd> para mudar entre os modos retrato e
+paisagem.
+
+Note que só será rotacionado se a aplicação em primeiro plano suportar a
+orientação requisitada.
+
+#### Copiar-colar
+
+Sempre que a área de transferência do Android muda, é automaticamente sincronizada com a
+área de transferência do computador.
+
+Qualquer atalho com <kbd>Ctrl</kbd> é encaminhado para o dispositivo. Em particular:
+ - <kbd>Ctrl</kbd>+<kbd>c</kbd> tipicamente copia
+ - <kbd>Ctrl</kbd>+<kbd>x</kbd> tipicamente recorta
+ - <kbd>Ctrl</kbd>+<kbd>v</kbd> tipicamente cola (após a sincronização de área de transferência
+   computador-para-dispositivo)
+
+Isso tipicamente funciona como esperado.
+
+O comportamento de fato depende da aplicação ativa, no entanto. Por exemplo,
+_Termux_ envia SIGINT com <kbd>Ctrl</kbd>+<kbd>c</kbd>, e _K-9 Mail_
+compõe uma nova mensagem.
+
+Para copiar, recortar e colar em tais casos (mas apenas suportado no Android >= 7):
+ - <kbd>MOD</kbd>+<kbd>c</kbd> injeta `COPY`
+ - <kbd>MOD</kbd>+<kbd>x</kbd> injeta `CUT`
+ - <kbd>MOD</kbd>+<kbd>v</kbd> injeta `PASTE` (após a sincronização de área de transferência
+   computador-para-dispositivo)
+
+Em adição, <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd> permite injetar o
+texto da área de transferência do computador como uma sequência de eventos de tecla. Isso é útil quando o
+componente não aceita colar texto (por exemplo no _Termux_), mas pode
+quebrar conteúdo não-ASCII.
+
+**ADVERTÊNCIA:** Colar a área de transferência do computador para o dispositivo (tanto via
+<kbd>Ctrl</kbd>+<kbd>v</kbd> quanto <kbd>MOD</kbd>+<kbd>v</kbd>) copia o conteúdo
+para a área de transferência do dispositivo. Como consequência, qualquer aplicação Android pode ler
+o seu conteúdo. Você deve evitar colar conteúdo sensível (como senhas) dessa
+forma.
+
+Alguns dispositivos não se comportam como esperado quando a área de transferência é definida
+programaticamente. Uma opção `--legacy-paste` é fornecida para mudar o comportamento
+de <kbd>Ctrl</kbd>+<kbd>v</kbd> e <kbd>MOD</kbd>+<kbd>v</kbd> para que eles
+também injetem o texto da área de transferência do computador como uma sequência de eventos de tecla (da mesma
+forma que <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd>).
+
+#### Pinçar para dar zoom
+
+Para simular "pinçar para dar zoom": <kbd>Ctrl</kbd>+_clicar-e-mover_.
+
+Mais precisamente, segure <kbd>Ctrl</kbd> enquanto pressiona o botão de clique-esquerdo. Até que
+o botão de clique-esquerdo seja liberado, todos os movimentos do mouse ampliar e rotacionam o
+conteúdo (se suportado pelo app) relativo ao centro da tela.
+
+Concretamente, scrcpy gera eventos adicionais de toque de um "dedo virtual" em
+uma posição invertida em relação ao centro da tela.
+
+
+#### Preferência de injeção de texto
+
+Existem dois tipos de [eventos][textevents] gerados ao digitar um texto:
+ - _eventos de tecla_, sinalizando que a tecla foi pressionada ou solta;
+ - _eventos de texto_, sinalizando que o texto foi inserido.
+
+Por padrão, letras são injetadas usando eventos de tecla, assim o teclado comporta-se
+como esperado em jogos (normalmente para teclas WASD).
+
+Mas isso pode [causar problemas][prefertext]. Se você encontrar tal problema, você
+pode evitá-lo com:
+
+```bash
+scrcpy --prefer-text
+```
+
+(mas isso vai quebrar o comportamento do teclado em jogos)
+
+[textevents]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-text-input
+[prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343
+
+
+#### Repetir tecla
+
+Por padrão, segurar uma tecla gera eventos de tecla repetidos. Isso pode causar
+problemas de performance em alguns jogos, onde esses eventos são inúteis de qualquer forma.
+
+Para evitar o encaminhamento eventos de tecla repetidos:
+
+```bash
+scrcpy --no-key-repeat
+```
+
+
+#### Clique-direito e clique-do-meio
+
+Por padrão, clique-direito dispara BACK (ou POWER) e clique-do-meio dispara
+HOME. Para desabilitar esses atalhos e encaminhar os cliques para o dispositivo:
+
+```bash
+scrcpy --forward-all-clicks
+```
+
+
+### Soltar arquivo
+
+#### Instalar APK
+
+Para instalar um APK, arraste e solte o arquivo APK (com extensão `.apk`) na janela
+_scrcpy_.
+
+Não existe feedback visual, um log é imprimido no console.
+
+
+#### Enviar arquivo para dispositivo
+
+Para enviar um arquivo para `/sdcard/Download/` no dispositivo, arraste e solte um arquivo (não-APK) para a
+janela do _scrcpy_.
+
+Não existe feedback visual, um log é imprimido no console.
+
+O diretório alvo pode ser mudado ao iniciar:
+
+```bash
+scrcpy --push-target /sdcard/foo/bar/
+```
+
+
+### Encaminhamento de áudio
+
+Áudio não é encaminhado pelo _scrcpy_. Use [sndcpy].
+
+Também veja [issue #14].
+
+[sndcpy]: https://github.com/rom1v/sndcpy
+[issue #14]: https://github.com/Genymobile/scrcpy/issues/14
+
+
+## Atalhos
+
+Na lista a seguir, <kbd>MOD</kbd> é o modificador de atalho. Por padrão, é
+<kbd>Alt</kbd> (esquerdo) ou <kbd>Super</kbd> (esquerdo).
+
+Ele pode ser mudado usando `--shortcut-mod`. Possíveis teclas são `lctrl`, `rctrl`,
+`lalt`, `ralt`, `lsuper` e `rsuper`. Por exemplo:
+
+```bash
+# usar RCtrl para atalhos
+scrcpy --shortcut-mod=rctrl
+
+# usar tanto LCtrl+LAlt quanto LSuper para atalhos
+scrcpy --shortcut-mod=lctrl+lalt,lsuper
+```
+
+_<kbd>[Super]</kbd> é tipicamente a tecla <kbd>Windows</kbd> ou <kbd>Cmd</kbd>._
+
+[Super]: https://en.wikipedia.org/wiki/Super_key_(keyboard_button)

+## Caminhos personalizados
+
+Para usar um binário _adb_ específico, configure seu caminho na variável de ambiente
+`ADB`:
+
+```bash
+ADB=/caminho/para/adb scrcpy
+```
+
+Para sobrepor o caminho do arquivo `scrcpy-server`, configure seu caminho em
+`SCRCPY_SERVER_PATH`.

+
+# scrcpy (v1.17)
+
+Esta aplicación proporciona imagen y control de un dispositivo Android conectado
+por USB (o [por TCP/IP][article-tcpip]). No requiere acceso _root_.
+Compatible con _GNU/Linux_, _Windows_ y _macOS_.
+
+![screenshot](assets/screenshot-debian-600.jpg)
+
+Sus características principales son:
+
+ - **ligero** (nativo, solo muestra la imagen del dispositivo)
+ - **desempeño** (30~60fps)
+ - **calidad** (1920×1080 o superior)
+ - **baja latencia** ([35~70ms][lowlatency])
+ - **corto tiempo de inicio** (~1 segundo para mostrar la primera imagen)
+ - **no intrusivo** (no se deja nada instalado en el dispositivo)
+
+[lowlatency]: https://github.com/Genymobile/scrcpy/pull/646
+
+
+## Requisitos
+
+El dispositivo Android requiere como mínimo API 21 (Android 5.0).
+
+Asegurate de [habilitar el adb debugging][enable-adb] en tu(s) dispositivo(s).
+
+[enable-adb]: https://developer.android.com/studio/command-line/adb.html#Enabling
+
+En algunos dispositivos, también necesitas habilitar [una opción adicional][control] para controlarlo con el teclado y ratón.

+
+[MacPorts]: https://www.macports.org/
+
+
+También puedes [construir la aplicación manualmente][BUILD].
+
+
+## Ejecutar
+
+Enchufa el dispositivo Android, y ejecuta:
+
+```bash
+scrcpy
+```
+
+Acepta argumentos desde la línea de comandos, listados en:
+
+```bash
+scrcpy --help
+```
+
+## Características
+
+### Capturar configuración
+
+#### Reducir la definición
+
+A veces es útil reducir la definición de la imagen del dispositivo Android para aumentar el desempeño.
+
+Para limitar el ancho y la altura a un valor específico (ej. 1024):
+
+```bash
+scrcpy --max-size 1024
+scrcpy -m 1024  # versión breve
+```
+
+La otra dimensión es calculada para conservar el aspect ratio del dispositivo.
+De esta forma, un dispositivo en 1920×1080 será transmitido a 1024×576.
+
+
+#### Cambiar el bit-rate
+
+El bit-rate por defecto es 8 Mbps. Para cambiar el bit-rate del video (ej. a 2 Mbps):
+
+```bash
+scrcpy --bit-rate 2M
+scrcpy -b 2M  # versión breve
+```
+
+#### Limitar los fps
+
+El fps puede ser limitado:
+
+```bash
+scrcpy --max-fps 15
+```
+
+Es oficialmente soportado desde Android 10, pero puede funcionar en versiones anteriores.
+
+#### Recortar
+
+La imagen del dispositivo puede ser recortada para transmitir solo una parte de la pantalla.
+
+Por ejemplo, puede ser útil para transmitir la imagen de un solo ojo del Oculus Go:
+
+```bash
+scrcpy --crop 1224:1440:0:0   # 1224x1440 con coordenadas de origen en (0,0)
+```
+
+Si `--max-size` también está especificado, el cambio de tamaño es aplicado después de cortar.
+
+
+#### Fijar la rotación del video
+
+
+Para fijar la rotación de la transmisión:
+
+```bash
+scrcpy --lock-video-orientation 0   # orientación normal
+scrcpy --lock-video-orientation 1   # 90° contrarreloj
+scrcpy --lock-video-orientation 2   # 180°
+scrcpy --lock-video-orientation 3   # 90° sentido de las agujas del reloj
+```
+
+Esto afecta la rotación de la grabación.
+
+La [ventana también puede ser rotada](#rotación) independientemente.
+
+
+#### Codificador
+
+Algunos dispositivos pueden tener más de una rotación, y algunos pueden causar problemas o errores. Es posible seleccionar un codificador diferente:
+
+```bash
+scrcpy --encoder OMX.qcom.video.encoder.avc
+```
+
+Para listar los codificadores disponibles, puedes pasar un nombre de codificador inválido, el error te dará los codificadores disponibles:
+
+```bash
+scrcpy --encoder _
+```
+
+### Grabación
+
+Es posible grabar la pantalla mientras se transmite:
+
+```bash
+scrcpy --record file.mp4
+scrcpy -r file.mkv
+```
+
+Para grabar sin transmitir la pantalla:
+
+```bash
+scrcpy --no-display --record file.mp4
+scrcpy -Nr file.mkv
+# interrumpe la grabación con Ctrl+C
+```
+
+"Skipped frames" son grabados, incluso si no son mostrados en tiempo real (por razones de desempeño). Los frames tienen _marcas de tiempo_ en el dispositivo, por lo que el "[packet delay
+variation]" no impacta el archivo grabado.
+
+[packet delay variation]: https://en.wikipedia.org/wiki/Packet_delay_variation
+
+
+### Conexión
+
+#### Inalámbrica
+
+_Scrcpy_ usa `adb` para comunicarse con el dispositivo, y `adb` puede [conectarse] vía TCP/IP:
+
+1. Conecta el dispositivo al mismo Wi-Fi que tu computadora.
+2. Obtén la dirección IP del dispositivo, en Ajustes → Acerca del dispositivo → Estado, o ejecutando este comando:
+
+    ```bash
+    adb shell ip route | awk '{print $9}'
+    ```
+
+3. Habilita adb vía TCP/IP en el dispositivo: `adb tcpip 5555`.
+4. Desenchufa el dispositivo.
+5. Conéctate a tu dispositivo: `adb connect IP_DEL_DISPOSITIVO:5555` _(reemplaza `IP_DEL_DISPOSITIVO`)_.
+6. Ejecuta `scrcpy` con normalidad.
+
+Podría resultar útil reducir el bit-rate y la definición:
+
+```bash
+scrcpy --bit-rate 2M --max-size 800
+scrcpy -b2M -m800  # versión breve
+```
+
+[conectarse]: https://developer.android.com/studio/command-line/adb.html#wireless
+
+
+#### Múltiples dispositivos
+
+Si hay muchos dispositivos listados en `adb devices`, será necesario especificar el _número de serie_:
+
+```bash
+scrcpy --serial 0123456789abcdef
+scrcpy -s 0123456789abcdef  # versión breve
+```
+
+Si el dispositivo está conectado por TCP/IP:
+
+```bash
+scrcpy --serial 192.168.0.1:5555
+scrcpy -s 192.168.0.1:5555  # versión breve
+```
+
+Puedes iniciar múltiples instancias de _scrcpy_ para múltiples dispositivos.
+
+#### Autoiniciar al detectar dispositivo
+
+Puedes utilizar [AutoAdb]:
+
+```bash
+autoadb scrcpy -s '{}'
+```
+
+[AutoAdb]: https://github.com/rom1v/autoadb
+
+#### Túnel SSH
+
+Para conectarse a un dispositivo remoto, es posible conectar un cliente local de `adb` a un servidor remoto `adb` (siempre y cuando utilicen la misma versión de protocolos _adb_):
+
+```bash
+adb kill-server    # cierra el servidor local adb en 5037
+ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 your_remote_computer
+# conserva este servidor abierto
+```
+
+Desde otra terminal:
+
+```bash
+scrcpy
+```
+
+Para evitar habilitar "remote port forwarding", puedes forzar una "forward connection" (nótese el argumento `-L` en vez de `-R`):
+
+```bash
+adb kill-server    # cierra el servidor local adb en 5037
+ssh -CN -L5037:localhost:5037 -L27183:localhost:27183 your_remote_computer
+# conserva este servidor abierto
+```
+
+Desde otra terminal:
+
+```bash
+scrcpy --force-adb-forward
+```
+
+
+Al igual que las conexiones inalámbricas, puede resultar útil reducir la calidad:
+
+```
+scrcpy -b2M -m800 --max-fps 15
+```
+
+### Configuración de la ventana
+
+#### Título
+
+Por defecto, el título de la ventana es el modelo del dispositivo. Puede ser modificado:
+
+```bash
+scrcpy --window-title 'My device'
+```
+
+#### Posición y tamaño
+
+La posición y tamaño inicial de la ventana puede ser especificado:
+
+```bash
+scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
+```
+
+#### Sin bordes
+
+Para deshabilitar el diseño de la ventana:
+
+```bash
+scrcpy --window-borderless
+```
+
+#### Siempre adelante
+
+Para mantener la ventana de scrcpy siempre adelante:
+
+```bash
+scrcpy --always-on-top
+```
+
+#### Pantalla completa
+
+La aplicación puede ser iniciada en pantalla completa:
+
+```bash
+scrcpy --fullscreen
+scrcpy -f  # versión breve
+```
+
+Puede entrar y salir de la pantalla completa con la combinación <kbd>MOD</kbd>+<kbd>f</kbd>.
+
+#### Rotación
+
+Se puede rotar la ventana:
+
+```bash
+scrcpy --rotation 1
+```
+
+Los valores posibles son:
+ - `0`: sin rotación
+ - `1`: 90 grados contrarreloj
+ - `2`: 180 grados
+ - `3`: 90 grados en sentido de las agujas del reloj
+
+La rotación también puede ser modificada con la combinación de teclas <kbd>MOD</kbd>+<kbd>←</kbd> _(izquierda)_ y <kbd>MOD</kbd>+<kbd>→</kbd> _(derecha)_.
+
+Nótese que _scrcpy_ maneja 3 diferentes rotaciones:
+ - <kbd>MOD</kbd>+<kbd>r</kbd> solicita al dispositivo cambiar entre vertical y horizontal (la aplicación en uso puede rechazarlo si no soporta la orientación solicitada).
+ - [`--lock-video-orientation`](#fijar-la-rotación-del-video) cambia la rotación de la transmisión (la orientación del video enviado a la PC). Esto afecta a la grabación.
+ - `--rotation` (o <kbd>MOD</kbd>+<kbd>←</kbd>/<kbd>MOD</kbd>+<kbd>→</kbd>) rota solo el contenido de la imagen. Esto solo afecta a la imagen mostrada, no a la grabación.
+
+
+### Otras opciones menores
+
+#### Solo lectura ("Read-only")
+
+Para deshabilitar los controles (todo lo que interactúe con el dispositivo: eventos del teclado, eventos del mouse, arrastrar y soltar archivos):
+
+```bash
+scrcpy --no-control
+scrcpy -n  # versión breve
+```
+
+#### Pantalla
+
+Si múltiples pantallas están disponibles, es posible elegir cual transmitir:
+
+```bash
+scrcpy --display 1
+```
+
+Los ids de las pantallas se pueden obtener con el siguiente comando:
+
+```bash
+adb shell dumpsys display   # busque "mDisplayId=" en la respuesta
+```
+
+La segunda pantalla solo puede ser manejada si el dispositivo cuenta con Android 10 (en caso contrario será transmitida en el modo solo lectura).
+
+
+#### Permanecer activo
+
+Para evitar que el dispositivo descanse después de un tiempo mientras está conectado:
+
+```bash
+scrcpy --stay-awake
+scrcpy -w  # versión breve
+```
+
+La configuración original se restaura al cerrar scrcpy.
+
+
+#### Apagar la pantalla
+
+Es posible apagar la pantalla mientras se transmite al iniciar con el siguiente comando:
+
+```bash
+scrcpy --turn-screen-off
+scrcpy -S  # versión breve
+```
+
+O presionando <kbd>MOD</kbd>+<kbd>o</kbd> en cualquier momento.
+
+Para volver a prenderla, presione <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>o</kbd>.
+
+En Android, el botón de `POWER` siempre prende la pantalla. Por conveniencia, si `POWER` es enviado vía scrcpy (con click-derecho o <kbd>MOD</kbd>+<kbd>p</kbd>), esto forzará a apagar la pantalla con un poco de atraso (en la mejor de las situaciones). El botón físico `POWER` seguirá prendiendo la pantalla.
+
+También puede resultar útil para evitar que el dispositivo entre en inactividad:
+
+```bash
+scrcpy --turn-screen-off --stay-awake
+scrcpy -Sw  # versión breve
+```
+
+
+#### Renderizar frames vencidos
+
+Por defecto, para minimizar la latencia, _scrcpy_ siempre renderiza el último frame disponible decodificado, e ignora cualquier frame anterior.
+
+Para forzar el renderizado de todos los frames (a costo de posible aumento de latencia), use:
+
+```bash
+scrcpy --render-expired-frames
+```
+
+#### Mostrar clicks
+
+Para presentaciones, puede resultar útil mostrar los clicks físicos (en el dispositivo físicamente).
+
+Android provee esta opción en _Opciones para desarrolladores_.
+
+_Scrcpy_ provee una opción para habilitar esta función al iniciar la aplicación y restaurar el valor original al salir:
+
+```bash
+scrcpy --show-touches
+scrcpy -t  # versión breve
+```
+
+Nótese que solo muestra los clicks _físicos_ (con el dedo en el dispositivo).
+
+
+#### Desactivar protector de pantalla
+
+Por defecto, scrcpy no evita que el protector de pantalla se active en la computadora.
+
+Para deshabilitarlo:
+
+```bash
+scrcpy --disable-screensaver
+```
+
+
+### Control
+
+#### Rotar pantalla del dispositivo
+
+Presione <kbd>MOD</kbd>+<kbd>r</kbd> para cambiar entre posición vertical y horizontal.
+
+Nótese que solo rotará si la aplicación activa soporta la orientación solicitada.
+
+#### Copiar y pegar
+
+Cuando que el portapapeles de Android cambia, automáticamente se sincroniza al portapapeles de la computadora.
+
+Cualquier shortcut con <kbd>Ctrl</kbd> es enviado al dispositivo. En particular:
+ - <kbd>Ctrl</kbd>+<kbd>c</kbd> normalmente copia
+ - <kbd>Ctrl</kbd>+<kbd>x</kbd> normalmente corta
+ - <kbd>Ctrl</kbd>+<kbd>v</kbd> normalmente pega (después de la sincronización de portapapeles entre la computadora y el dispositivo)
+
+Esto normalmente funciona como es esperado.
+
+Sin embargo, este comportamiento depende de la aplicación en uso. Por ejemplo, _Termux_ envía SIGINT con <kbd>Ctrl</kbd>+<kbd>c</kbd>, y _K-9 Mail_ crea un nuevo mensaje.
+
+Para copiar, cortar y pegar, en tales casos (solo soportado en Android >= 7):
+ - <kbd>MOD</kbd>+<kbd>c</kbd> inyecta `COPY`
+ - <kbd>MOD</kbd>+<kbd>x</kbd> inyecta `CUT`
+ - <kbd>MOD</kbd>+<kbd>v</kbd> inyecta `PASTE` (después de la sincronización de portapapeles entre la computadora y el dispositivo)
+
+Además, <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd> permite inyectar el texto en el portapapeles de la computadora como una secuencia de teclas. Esto es útil cuando el componente no acepta pegado de texto (por ejemplo en _Termux_), pero puede romper caracteres no pertenecientes a ASCII.
+
+**AVISO:** Pegar de la computadora al dispositivo (tanto con <kbd>Ctrl</kbd>+<kbd>v</kbd> o <kbd>MOD</kbd>+<kbd>v</kbd>) copia el contenido al portapapeles del dispositivo. Como consecuencia, cualquier aplicación de Android puede leer su contenido. Debería evitar pegar contenido sensible (como contraseñas) de esta forma.
+
+Algunos dispositivos no se comportan como es esperado al establecer el portapapeles programáticamente. La opción `--legacy-paste` está disponible para cambiar el comportamiento de <kbd>Ctrl</kbd>+<kbd>v</kbd> y <kbd>MOD</kbd>+<kbd>v</kbd> para que también inyecten el texto del portapapeles de la computadora como una secuencia de teclas (de la misma forma que <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd>).
+
+#### Pellizcar para zoom
+
+Para simular "pinch-to-zoom": <kbd>Ctrl</kbd>+_click-y-mover_.
+
+Más precisamente, mantén <kbd>Ctrl</kbd> mientras presionas botón izquierdo. Hasta que no se suelte el botón, todos los movimientos del mouse cambiarán el tamaño y rotación del contenido (si es soportado por la app en uso) respecto al centro de la pantalla.
+
+Concretamente, scrcpy genera clicks adicionales con un "dedo virtual" en la posición invertida respecto al centro de la pantalla.
+
+
+#### Preferencias de inyección de texto
+
+Existen dos tipos de [eventos][textevents] generados al escribir texto:
+ - _key events_, marcando si la tecla es presionada o soltada;
+ - _text events_, marcando si un texto fue introducido.
+
+Por defecto, las letras son inyectadas usando _key events_, para que el teclado funcione como es esperado en juegos (típicamente las teclas WASD).
+
+Pero esto puede [causar problemas][prefertext]. Si encuentras tales problemas, los puedes evitar con:
+
+```bash
+scrcpy --prefer-text
+```
+
+(Pero esto romperá el comportamiento del teclado en los juegos)
+
+[textevents]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-text-input
+[prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343
+
+
+#### Repetir tecla
+
+Por defecto, mantener una tecla presionada genera múltiples _key events_. Esto puede causar problemas de desempeño en algunos juegos, donde estos eventos no tienen sentido de todos modos.
+
+Para evitar enviar _key events_ repetidos:
+
+```bash
+scrcpy --no-key-repeat
+```
+
+
+#### Botón derecho y botón del medio
+
+Por defecto, botón derecho ejecuta RETROCEDER (o ENCENDIDO) y botón del medio INICIO. Para inhabilitar estos atajos y enviar los clicks al dispositivo:
+
+```bash
+scrcpy --forward-all-clicks
+```
+
+
+### Arrastrar y soltar archivos
+
+#### Instalar APKs
+
+Para instalar un APK, arrastre y suelte el archivo APK (terminado en `.apk`) a la ventana de _scrcpy_.
+
+No hay respuesta visual, un mensaje se escribirá en la consola.
+
+
+#### Enviar archivos al dispositivo
+
+Para enviar un archivo a `/sdcard/` en el dispositivo, arrastre y suelte un archivo (no APK) a la ventana de _scrcpy_.
+
+No hay respuesta visual, un mensaje se escribirá en la consola.
+
+El directorio de destino puede ser modificado al iniciar:
+
+```bash
+scrcpy --push-target=/sdcard/Download/
+```
+
+
+### Envío de Audio
+
+_Scrcpy_ no envía el audio. Use [sndcpy].

+En la siguiente lista, <kbd>MOD</kbd> es el atajo modificador. Por defecto es <kbd>Alt</kbd> (izquierdo) o <kbd>Super</kbd> (izquierdo).
+
+Se puede modificar usando `--shortcut-mod`. Las posibles teclas son `lctrl` (izquierdo), `rctrl` (derecho), `lalt` (izquierdo), `ralt` (derecho), `lsuper` (izquierdo) y `rsuper` (derecho). Por ejemplo:
+
+```bash
+# use RCtrl para los atajos
+scrcpy --shortcut-mod=rctrl
+
+# use tanto LCtrl+LAlt o LSuper para los atajos
+scrcpy --shortcut-mod=lctrl+lalt,lsuper
+```
+
+_<kbd>[Super]</kbd> es generalmente la tecla <kbd>Windows</kbd> o <kbd>Cmd</kbd>._

+ADB=/path/to/adb scrcpy
+```
+
+Para sobreescribir el path del archivo `scrcpy-server`, configure el path en `SCRCPY_SERVER_PATH`.
+
+
+## ¿Por qué _scrcpy_?
+
+Un colega me retó a encontrar un nombre tan impronunciable como [gnirehtet].

+scrcpy
+```
+
+Komut satırı argümanları aşağıdaki komut ile listelenebilir:
+
+```bash
+scrcpy --help
+```
+
+## Özellikler
+
+### Ekran yakalama ayarları
+
+#### Boyut azaltma
+
+Bazen, Android cihaz ekranını daha düşük seviyede göstermek performansı artırabilir.
+
+Hem genişliği hem de yüksekliği bir değere sabitlemek için (ör. 1024):
+
+```bash
+scrcpy --max-size 1024
+scrcpy -m 1024  # kısa versiyon
+```
+
+Diğer boyut en-boy oranı korunacak şekilde hesaplanır.
+Bu şekilde ekran boyutu 1920x1080 olan bir cihaz 1024x576 olarak görünür.
+
+#### Bit-oranı değiştirme
+
+Varsayılan bit-oranı 8 Mbps'dir. Değiştirmek için (ör. 2 Mbps):
+
+```bash
+scrcpy --bit-rate 2M
+scrcpy -b 2M  # kısa versiyon
+```
+
+#### Çerçeve oranı sınırlama
+
+Ekran yakalama için maksimum çerçeve oranı için sınır koyulabilir:
+
+```bash
+scrcpy --max-fps 15
+```
+
+Bu özellik Android 10 ve sonrası sürümlerde resmi olarak desteklenmektedir,
+ancak daha önceki sürümlerde çalışmayabilir.
+
+#### Kesme
+
+Cihaz ekranının sadece bir kısmı görünecek şekilde kesilebilir.
+
+Bu özellik Oculus Go'nun bir gözünü yakalamak gibi durumlarda kullanışlı olur:
+
+```bash
+scrcpy --crop 1224:1440:0:0   # (0,0) noktasından 1224x1440
+```
+
+Eğer `--max-size` belirtilmişse yeniden boyutlandırma kesme işleminden sonra yapılır.
+
+#### Video yönünü kilitleme
+
+Videonun yönünü kilitlemek için:
+
+```bash
+scrcpy --lock-video-orientation     # başlangıç yönü
+scrcpy --lock-video-orientation=0   # doğal yön
+scrcpy --lock-video-orientation=1   # 90° saatin tersi yönü
+scrcpy --lock-video-orientation=2   # 180°
+scrcpy --lock-video-orientation=3   # 90° saat yönü
+```
+
+Bu özellik kaydetme yönünü de etkiler.
+
+[Pencere ayrı olarak döndürülmüş](#rotation) olabilir.
+
+#### Kodlayıcı
+
+Bazı cihazlar birden fazla kodlayıcıya sahiptir, ve bunların bazıları programın
+kapanmasına sebep olabilir. Bu durumda farklı bir kodlayıcı seçilebilir:
+
+```bash
+scrcpy --encoder OMX.qcom.video.encoder.avc
+```
+
+Mevcut kodlayıcıları listelemek için geçerli olmayan bir kodlayıcı ismi girebilirsiniz,
+hata mesajı mevcut kodlayıcıları listeleyecektir:
+
+```bash
+scrcpy --encoder _
+```
+
+### Yakalama
+
+#### Kaydetme
+
+Ekran yakalama sırasında kaydedilebilir:
+
+```bash
+scrcpy --record file.mp4
+scrcpy -r file.mkv
+```
+
+Yakalama olmadan kayıt için:
+
+```bash
+scrcpy --no-display --record file.mp4
+scrcpy -Nr file.mkv
+# Ctrl+C ile kayıt kesilebilir
+```
+
+"Atlanan kareler" gerçek zamanlı olarak gösterilmese (performans sebeplerinden ötürü) dahi kaydedilir.
+Kareler cihazda _zamandamgası_ ile saklanır, bu sayede [paket gecikme varyasyonu]
+kayıt edilen dosyayı etkilemez.
+
+[paket gecikme varyasyonu]: https://en.wikipedia.org/wiki/Packet_delay_variation
+
+#### v4l2loopback
+
+Linux'ta video akışı bir v4l2 loopback cihazına gönderilebilir. Bu sayede Android
+cihaz bir web kamerası gibi davranabilir.
+
+Bu işlem için `v4l2loopback` modülü kurulu olmalıdır:
+
+```bash
+sudo apt install v4l2loopback-dkms
+```
+
+v4l2 cihazı oluşturmak için:
+
+```bash
+sudo modprobe v4l2loopback
+```
+
+Bu komut `/dev/videoN` adresinde `N` yerine bir tamsayı koyarak yeni bir video
+cihazı oluşturacaktır.
+(birden fazla cihaz oluşturmak veya spesifik ID'ye sahip cihazlar için
+diğer [seçenekleri](https://github.com/umlaeute/v4l2loopback#options) inceleyebilirsiniz.)
+
+Aktif cihazları listelemek için:
+
+```bash
+# v4l-utils paketi ile
+v4l2-ctl --list-devices
+
+# daha basit ama yeterli olabilecek şekilde
+ls /dev/video*
+```
+
+v4l2 kullanarak scrpy kullanmaya başlamak için:
+
+```bash
+scrcpy --v4l2-sink=/dev/videoN
+scrcpy --v4l2-sink=/dev/videoN --no-display  # ayna penceresini kapatarak
+scrcpy --v4l2-sink=/dev/videoN -N            # kısa versiyon
+```
+
+(`N` harfini oluşturulan cihaz ID numarası ile değiştirin. `ls /dev/video*` cihaz ID'lerini görebilirsiniz.)
+
+Aktifleştirildikten sonra video akışını herhangi bir v4l2 özellikli araçla açabilirsiniz:
+
+```bash
+ffplay -i /dev/videoN
+vlc v4l2:///dev/videoN   # VLC kullanırken yükleme gecikmesi olabilir
+```
+
+Örneğin, [OBS] ile video akışını kullanabilirsiniz.
+

+
+### Bağlantı
+
+#### Kablosuz
+
+_Scrcpy_ cihazla iletişim kurmak için `adb`'yi kullanır, Ve `adb`
+bir cihaza TCP/IP kullanarak [bağlanabilir].
+
+1. Cihazınızı bilgisayarınızla aynı Wi-Fi ağına bağlayın.
+2. Cihazınızın IP adresini bulun. Ayarlar → Telefon Hakkında → Durum sekmesinden veya
+   aşağıdaki komutu çalıştırarak öğrenebilirsiniz:
+
+   ```bash
+   adb shell ip route | awk '{print $9}'
+   ```
+
+3. Cihazınızda TCP/IP üzerinden adb kullanımını etkinleştirin: `adb tcpip 5555`.
+4. Cihazınızı bilgisayarınızdan sökün.
+5. Cihazınıza bağlanın: `adb connect DEVICE_IP:5555` _(`DEVICE_IP` değerini değiştirin)_.
+6. `scrcpy` komutunu normal olarak çalıştırın.
+
+Bit-oranını ve büyüklüğü azaltmak yararlı olabilir:
+
+```bash
+scrcpy --bit-rate 2M --max-size 800
+scrcpy -b2M -m800  # kısa version
+```
+
+[bağlanabilir]: https://developer.android.com/studio/command-line/adb.html#wireless
+
+#### Birden fazla cihaz
+
+Eğer `adb devices` komutu birden fazla cihaz listeliyorsa _serial_ değerini belirtmeniz gerekir:
+
+```bash
+scrcpy --serial 0123456789abcdef
+scrcpy -s 0123456789abcdef  # kısa versiyon
+```
+
+Eğer cihaz TCP/IP üzerinden bağlanmışsa:
+
+```bash
+scrcpy --serial 192.168.0.1:5555
+scrcpy -s 192.168.0.1:5555  # kısa version
+```
+
+Birden fazla cihaz için birden fazla _scrcpy_ uygulaması çalıştırabilirsiniz.
+
+#### Cihaz bağlantısı ile otomatik başlatma
+
+[AutoAdb] ile yapılabilir:
+
+```bash
+autoadb scrcpy -s '{}'
+```
+
+[autoadb]: https://github.com/rom1v/autoadb
+
+#### SSH Tünel
+
+Uzaktaki bir cihaza erişmek için lokal `adb` istemcisi, uzaktaki bir `adb` sunucusuna
+(aynı _adb_ sürümünü kullanmak şartı ile) bağlanabilir :
+
+```bash
+adb kill-server    # 5037 portunda çalışan lokal adb sunucusunu kapat
+ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 your_remote_computer
+# bunu açık tutun
+```
+
+Başka bir terminalde:
+
+```bash
+scrcpy
+```
+
+Uzaktan port yönlendirme ileri yönlü bağlantı kullanabilirsiniz
+(`-R` yerine `-L` olduğuna dikkat edin):
+
+```bash
+adb kill-server    # 5037 portunda çalışan lokal adb sunucusunu kapat
+ssh -CN -L5037:localhost:5037 -L27183:localhost:27183 your_remote_computer
+# bunu açık tutun
+```
+
+Başka bir terminalde:
+
+```bash
+scrcpy --force-adb-forward
+```
+
+Kablosuz bağlantı gibi burada da kalite düşürmek faydalı olabilir:
+
+```
+scrcpy -b2M -m800 --max-fps 15
+```
+
+### Pencere ayarları
+
+#### İsim
+
+Cihaz modeli varsayılan pencere ismidir. Değiştirmek için:
+
+```bash
+scrcpy --window-title 'Benim cihazım'
+```
+
+#### Konum ve
+
+Pencerenin başlangıç konumu ve boyutu belirtilebilir:
+
+```bash
+scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
+```
+
+#### Kenarlıklar
+
+Pencere dekorasyonunu kapatmak için:
+
+```bash
+scrcpy --window-borderless
+```
+
+#### Her zaman üstte
+
+Scrcpy penceresini her zaman üstte tutmak için:
+
+```bash
+scrcpy --always-on-top
+```
+
+#### Tam ekran
+
+Uygulamayı tam ekran başlatmak için:
+
+```bash
+scrcpy --fullscreen
+scrcpy -f  # kısa versiyon
+```
+
+Tam ekran <kbd>MOD</kbd>+<kbd>f</kbd> ile dinamik olarak değiştirilebilir.
+
+#### Döndürme
+
+Pencere döndürülebilir:
+
+```bash
+scrcpy --rotation 1
+```
+
+Seçilebilecek değerler:
+
+- `0`: döndürme yok
+- `1`: 90 derece saat yönünün tersi
+- `2`: 180 derece
+- `3`: 90 derece saat yönü
+
+Döndürme <kbd>MOD</kbd>+<kbd>←</kbd>_(sol)_ ve
+<kbd>MOD</kbd>+<kbd>→</kbd> _(sağ)_ ile dinamik olarak değiştirilebilir.
+
+_scrcpy_'de 3 farklı döndürme olduğuna dikkat edin:
+
+- <kbd>MOD</kbd>+<kbd>r</kbd> cihazın yatay veya dikey modda çalışmasını sağlar.
+  (çalışan uygulama istenilen oryantasyonda çalışmayı desteklemiyorsa döndürme
+  işlemini reddedebilir.)
+- [`--lock-video-orientation`](#lock-video-orientation) görüntü yakalama oryantasyonunu
+  (cihazdan bilgisayara gelen video akışının oryantasyonu) değiştirir. Bu kayıt işlemini
+  etkiler.
+- `--rotation` (or <kbd>MOD</kbd>+<kbd>←</kbd>/<kbd>MOD</kbd>+<kbd>→</kbd>)
+  pencere içeriğini dönderir. Bu sadece canlı görüntüyü etkiler, kayıt işlemini etkilemez.
+
+### Diğer ekran yakalama seçenekleri
+
+#### Yazma korumalı
+
+Kontrolleri devre dışı bırakmak için (cihazla etkileşime geçebilecek her şey: klavye ve
+fare girdileri, dosya sürükleyip bırakma):
+
+```bash
+scrcpy --no-control
+scrcpy -n
+```
+
+#### Ekran
+
+Eğer cihazın birden fazla ekranı varsa hangi ekranın kullanılacağını seçebilirsiniz:
+
+```bash
+scrcpy --display 1
+```
+
+Kullanılabilecek ekranları listelemek için:
+
+```bash
+adb shell dumpsys display   # çıktı içerisinde "mDisplayId=" terimini arayın
+```
+
+İkinci ekran ancak cihaz Android sürümü 10 veya üzeri olmalıdır (değilse yazma korumalı
+olarak görüntülenir).
+
+#### Uyanık kalma
+
+Cihazın uyku moduna girmesini engellemek için:
+
+```bash
+scrcpy --stay-awake
+scrcpy -w
+```
+
+scrcpy kapandığında cihaz başlangıç durumuna geri döner.
+
+#### Ekranı kapatma
+
+Ekran yakalama sırasında cihazın ekranı kapatılabilir:
+
+```bash
+scrcpy --turn-screen-off
+scrcpy -S
+```
+
+Ya da <kbd>MOD</kbd>+<kbd>o</kbd> kısayolunu kullanabilirsiniz.
+
+Tekrar açmak için ise <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>o</kbd> tuşlarına basın.
+
+Android'de, `GÜÇ` tuşu her zaman ekranı açar. Eğer `GÜÇ` sinyali scrcpy ile
+gönderilsiyse (sağ tık veya <kbd>MOD</kbd>+<kbd>p</kbd>), ekran kısa bir gecikme
+ile kapanacaktır. Fiziksel `GÜÇ` tuşuna basmak hala ekranın açılmasına sebep olacaktır.
+
+Bu cihazın uykuya geçmesini engellemek için kullanılabilir:
+
+```bash
+scrcpy --turn-screen-off --stay-awake
+scrcpy -Sw
+```
+
+#### Dokunuşları gösterme
+
+Sunumlar sırasında fiziksel dokunuşları (fiziksel cihazdaki) göstermek
+faydalı olabilir.
+
+Android'de bu özellik _Geliştici seçenekleri_ içerisinde bulunur.
+
+_Scrcpy_ bu özelliği çalışırken etkinleştirebilir ve kapanırken eski
+haline geri getirebilir:
+
+```bash
+scrcpy --show-touches
+scrcpy -t
+```
+
+Bu opsiyon sadece _fiziksel_ dokunuşları (cihaz ekranındaki) gösterir.
+
+#### Ekran koruyucuyu devre dışı bırakma
+
+Scrcpy varsayılan ayarlarında ekran koruyucuyu devre dışı bırakmaz.
+
+Bırakmak için:
+
+```bash
+scrcpy --disable-screensaver
+```
+
+### Girdi kontrolü
+
+#### Cihaz ekranını dönderme
+
+<kbd>MOD</kbd>+<kbd>r</kbd> tuşları ile yatay ve dikey modlar arasında
+geçiş yapabilirsiniz.
+
+Bu kısayol ancak çalışan uygulama desteklediği takdirde ekranı döndürecektir.
+
+#### Kopyala yapıştır
+
+Ne zaman Android cihazdaki pano değişse bilgisayardaki pano otomatik olarak
+senkronize edilir.
+
+Tüm <kbd>Ctrl</kbd> kısayolları cihaza iletilir:
+
+- <kbd>Ctrl</kbd>+<kbd>c</kbd> genelde kopyalar
+- <kbd>Ctrl</kbd>+<kbd>x</kbd> genelde keser
+- <kbd>Ctrl</kbd>+<kbd>v</kbd> genelde yapıştırır (bilgisayar ve cihaz arasındaki
+  pano senkronizasyonundan sonra)
+
+Bu kısayollar genelde beklediğiniz gibi çalışır.
+
+Ancak kısayolun gerçekten yaptığı eylemi açık olan uygulama belirler.
+Örneğin, _Termux_ <kbd>Ctrl</kbd>+<kbd>c</kbd> ile kopyalama yerine
+SIGINT sinyali gönderir, _K-9 Mail_ ise yeni mesaj oluşturur.
+
+Bu tip durumlarda kopyalama, kesme ve yapıştırma için (Android versiyon 7 ve
+üstü):
+
+- <kbd>MOD</kbd>+<kbd>c</kbd> `KOPYALA`
+- <kbd>MOD</kbd>+<kbd>x</kbd> `KES`
+- <kbd>MOD</kbd>+<kbd>v</kbd> `YAPIŞTIR` (bilgisayar ve cihaz arasındaki
+  pano senkronizasyonundan sonra)
+
+Bunlara ek olarak, <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd> tuşları
+bilgisayar pano içeriğini tuş basma eylemleri şeklinde gönderir. Bu metin
+yapıştırmayı desteklemeyen (_Termux_ gibi) uygulamar için kullanışlıdır,
+ancak ASCII olmayan içerikleri bozabilir.
+
+**UYARI:** Bilgisayar pano içeriğini cihaza yapıştırmak
+(<kbd>Ctrl</kbd>+<kbd>v</kbd> ya da <kbd>MOD</kbd>+<kbd>v</kbd> tuşları ile)
+içeriği cihaz panosuna kopyalar. Sonuç olarak, herhangi bir Android uygulaması
+içeriğe erişebilir. Hassas içerikler (parolalar gibi) için bu özelliği kullanmaktan
+kaçının.
+
+Bazı cihazlar pano değişikleri konusunda beklenilen şekilde çalışmayabilir.
+Bu durumlarda `--legacy-paste` argümanı kullanılabilir. Bu sayede
+<kbd>Ctrl</kbd>+<kbd>v</kbd> ve <kbd>MOD</kbd>+<kbd>v</kbd> tuşları da
+pano içeriğini tuş basma eylemleri şeklinde gönderir
+(<kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd> ile aynı şekilde).
+
+#### İki parmak ile yakınlaştırma
+
+"İki parmak ile yakınlaştırma" için: <kbd>Ctrl</kbd>+_tıkla-ve-sürükle_.
+
+Daha açıklayıcı şekilde, <kbd>Ctrl</kbd> tuşuna sol-tık ile birlikte basılı
+tutun. Sol-tık serbest bırakılıncaya kadar yapılan tüm fare hareketleri
+ekran içeriğini ekranın merkezini baz alarak dönderir, büyütür veya küçültür
+(eğer uygulama destekliyorsa).
+
+Scrcpy ekranın merkezinde bir "sanal parmak" varmış gibi davranır.
+
+#### Metin gönderme tercihi
+
+Metin girilirken ili çeşit [eylem][textevents] gerçekleştirilir:
+
+- _tuş eylemleri_, bir tuşa basıldığı sinyalini verir;
+- _metin eylemleri_, bir metin girildiği sinyalini verir.
+
+Varsayılan olarak, harfler tuş eylemleri kullanılarak gönderilir. Bu sayede
+klavye oyunlarda beklenilene uygun olarak çalışır (Genelde WASD tuşları).
+
+Ancak bu [bazı problemlere][prefertext] yol açabilir. Eğer bu problemler ile
+karşılaşırsanız metin eylemlerini tercih edebilirsiniz:
+
+```bash
+scrcpy --prefer-text
+```
+
+(Ama bu oyunlardaki klavye davranışlarını bozacaktır)
+
+[textevents]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-text-input
+[prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343
+
+#### Tuş tekrarı
+
+Varsayılan olarak, bir tuşa basılı tutmak tuş eylemini tekrarlar. Bu durum
+bazı oyunlarda problemlere yol açabilir.
+
+Tuş eylemlerinin tekrarını kapatmak için:
+
+```bash
+scrcpy --no-key-repeat
+```
+
+#### Sağ-tık ve Orta-tık
+
+Varsayılan olarak, sağ-tık GERİ (ya da GÜÇ açma) eylemlerini, orta-tık ise
+ANA EKRAN eylemini tetikler. Bu kısayolları devre dışı bırakmak için:
+
+```bash
+scrcpy --forward-all-clicks
+```
+
+### Dosya bırakma
+
+#### APK kurulumu
+
+APK kurmak için, bilgisayarınızdaki APK dosyasını (`.apk` ile biten) _scrcpy_
+penceresine sürükleyip bırakın.
+
+Bu eylem görsel bir geri dönüt oluşturmaz, konsola log yazılır.
+
+#### Dosyayı cihaza gönderme
+
+Bir dosyayı cihazdaki `/sdcard/Download/` dizinine atmak için, (APK olmayan)
+bir dosyayı _scrcpy_ penceresine sürükleyip bırakın.
+
+Bu eylem görsel bir geri dönüt oluşturmaz, konsola log yazılır.
+
+Hedef dizin uygulama başlatılırken değiştirilebilir:
+
+```bash
+scrcpy --push-target=/sdcard/Movies/
+```
+
+### Ses iletimi
+
+_Scrcpy_ ses iletimi yapmaz. Yerine [sndcpy] kullanabilirsiniz.
+

+
+## Kısayollar
+
+Aşağıdaki listede, <kbd>MOD</kbd> kısayol tamamlayıcısıdır. Varsayılan olarak
+(sol) <kbd>Alt</kbd> veya (sol) <kbd>Super</kbd> tuşudur.
+
+Bu tuş `--shortcut-mod` argümanı kullanılarak `lctrl`, `rctrl`,
+`lalt`, `ralt`, `lsuper` ve `rsuper` tuşlarından biri ile değiştirilebilir.
+Örneğin:
+
+```bash
+# Sağ Ctrl kullanmak için
+scrcpy --shortcut-mod=rctrl
+
+# Sol Ctrl, Sol Alt veya Sol Super tuşlarından birini kullanmak için
+scrcpy --shortcut-mod=lctrl+lalt,lsuper
+```
+
+_<kbd>[Super]</kbd> tuşu genelde <kbd>Windows</kbd> veya <kbd>Cmd</kbd> tuşudur._
+

+## 运行
+
+连接安卓设备，然后执行：
+
+```bash
+scrcpy
+```
+
+本程序支持命令行参数，查看参数列表：
+
+```bash
+scrcpy --help
+```
+
+## 功能介绍
+
+### 采集设置
+
+#### 降低分辨率
+
+有时候，可以通过降低镜像的分辨率来提高性能。
+
+要同时限制宽度和高度到某个值 (例如 1024)：
+
+```bash
+scrcpy --max-size 1024
+scrcpy -m 1024  # 简写
+```
+
+另一边会被按比例缩小以保持设备的显示比例。这样，1920×1080 分辨率的设备会以 1024×576 的分辨率进行镜像。
+
+
+#### 修改码率
+
+默认码率是 8 Mbps。改变视频码率 (例如改为 2 Mbps)：
+
+```bash
+scrcpy --bit-rate 2M
+scrcpy -b 2M  # 简写
+```
+
+#### 限制帧率
+
+要限制采集的帧率：
+
+```bash
+scrcpy --max-fps 15
+```
+
+本功能从 Android 10 开始才被官方支持，但在一些旧版本中也能生效。
+
+#### 画面裁剪
+
+可以对设备屏幕进行裁剪，只镜像屏幕的一部分。
+
+例如可以只镜像 Oculus Go 的一只眼睛。
+
+```bash
+scrcpy --crop 1224:1440:0:0   # 以 (0,0) 为原点的 1224x1440 像素
+```
+
+如果同时指定了 `--max-size`，会先进行裁剪，再进行缩放。
+
+
+#### 锁定屏幕方向
+
+
+要锁定镜像画面的方向：
+
+```bash
+scrcpy --lock-video-orientation     # 初始（目前）方向
+scrcpy --lock-video-orientation=0   # 自然方向
+scrcpy --lock-video-orientation=1   # 逆时针旋转 90°
+scrcpy --lock-video-orientation=2   # 180°
+scrcpy --lock-video-orientation=3   # 顺时针旋转 90°
+```
+
+只影响录制的方向。
+
+[窗口可以独立旋转](#旋转)。
+
+
+#### 编码器
+
+一些设备内置了多种编码器，但是有的编码器会导致问题或崩溃。可以手动选择其它编码器：
+
+```bash
+scrcpy --encoder OMX.qcom.video.encoder.avc
+```
+
+要列出可用的编码器，可以指定一个不存在的编码器名称，错误信息中会包含所有的编码器：
+
+```bash
+scrcpy --encoder _
+```
+
+### 采集
+
+#### 屏幕录制
+
+可以在镜像的同时录制视频：
+
+```bash
+scrcpy --record file.mp4
+scrcpy -r file.mkv
+```
+
+仅录制，不显示镜像：
+
+```bash
+scrcpy --no-display --record file.mp4
+scrcpy -Nr file.mkv
+# 按 Ctrl+C 停止录制
+```
+
+录制时会包含“被跳过的帧”，即使它们由于性能原因没有实时显示。设备会为每一帧打上 _时间戳_ ，所以 [包时延抖动][packet delay variation] 不会影响录制的文件。
+
+[packet delay variation]: https://en.wikipedia.org/wiki/Packet_delay_variation
+
+
+#### v4l2loopback
+
+在 Linux 上，可以将视频流发送至 v4l2 回环 (loopback) 设备，因此可以使用任何 v4l2 工具像摄像头一样打开安卓设备。
+
+需安装 `v4l2loopback` 模块：
+
+```bash
+sudo apt install v4l2loopback-dkms
+```
+
+创建一个 v4l2 设备：
+
+```bash
+sudo modprobe v4l2loopback
+```
+
+这样会在 `/dev/videoN` 创建一个新的视频设备，其中 `N` 是整数。 ([更多选项](https://github.com/umlaeute/v4l2loopback#options) 可以用来创建多个设备或者特定 ID 的设备)。
+
+列出已启用的设备：
+
+```bash
+# 需要 v4l-utils 包
+v4l2-ctl --list-devices
+
+# 简单但或许足够
+ls /dev/video*
+```
+
+使用一个 v4l2 漏开启 scrcpy：
+
+```bash
+scrcpy --v4l2-sink=/dev/videoN
+scrcpy --v4l2-sink=/dev/videoN --no-display  # 禁用窗口镜像
+scrcpy --v4l2-sink=/dev/videoN -N            # 简写
+```
+
+(将 `N` 替换为设备 ID，使用 `ls /dev/video*` 命令查看)
+
+启用之后，可以使用 v4l2 工具打开视频流：
+
+```bash
+ffplay -i /dev/videoN
+vlc v4l2:///dev/videoN   # VLC 可能存在一些缓冲延迟
+```
+
+例如，可以在 [OBS] 中采集视频。
+
+[OBS]: https://obsproject.com/
+
+
+#### 缓冲
+
+可以加入缓冲，会增加延迟，但可以减少抖动 (见 [#2464])。
+
+[#2464]: https://github.com/Genymobile/scrcpy/issues/2464
+
+对于显示缓冲：
+
+```bash
+scrcpy --display-buffer=50  # 为显示增加 50 毫秒的缓冲
+```
+
+对于 V4L2 漏:
+
+```bash
+scrcpy --v4l2-buffer=500    # 为 v4l2 漏增加 500 毫秒的缓冲
+```
+
+
+### 连接
+
+#### 无线
+
+_Scrcpy_ 使用 `adb` 与设备通信，并且 `adb` 支持通过 TCP/IP [连接]到设备:
+
+1. 将设备和电脑连接至同一 Wi-Fi。
+2. 打开 设置 → 关于手机 → 状态信息，获取设备的 IP 地址，也可以执行以下的命令：
+
+    ```bash
+    adb shell ip route | awk '{print $9}'
+    ```
+
+3. 启用设备的网络 adb 功能： `adb tcpip 5555`。
+4. 断开设备的 USB 连接。
+5. 连接到您的设备：`adb connect DEVICE_IP:5555` _(将 `DEVICE_IP` 替换为设备 IP)_。
+6. 正常运行 `scrcpy`。
+
+可能降低码率和分辨率会更好一些：
+
+```bash
+scrcpy --bit-rate 2M --max-size 800
+scrcpy -b2M -m800  # 简写
+```
+
+[连接]: https://developer.android.com/studio/command-line/adb.html#wireless
+
+
+#### 多设备
+
+如果 `adb devices` 列出了多个设备，您必须指定设备的 _序列号_ ：
+
+```bash
+scrcpy --serial 0123456789abcdef
+scrcpy -s 0123456789abcdef  # 简写
+```
+
+如果设备通过 TCP/IP 连接：
+
+```bash
+scrcpy --serial 192.168.0.1:5555
+scrcpy -s 192.168.0.1:5555  # 简写
+```
+
+您可以同时启动多个 _scrcpy_ 实例以同时显示多个设备的画面。
+
+#### 在设备连接时自动启动
+
+您可以使用 [AutoAdb]:
+
+```bash
+autoadb scrcpy -s '{}'
+```
+
+[AutoAdb]: https://github.com/rom1v/autoadb
+
+#### SSH 隧道
+
+要远程连接到设备，可以将本地的 adb 客户端连接到远程的 adb 服务端 (需要两端的 _adb_ 协议版本相同)：
+
+```bash
+adb kill-server    # 关闭本地 5037 端口上的 adb 服务端
+ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 your_remote_computer
+# 保持该窗口开启
+```
+
+在另一个终端：
+
+```bash
+scrcpy
+```
+
+若要不使用远程端口转发，可以强制使用正向连接 (注意 `-L` 和 `-R` 的区别)：
+
+```bash
+adb kill-server    # 关闭本地 5037 端口上的 adb 服务端
+ssh -CN -L5037:localhost:5037 -L27183:localhost:27183 your_remote_computer
+# 保持该窗口开启
+```
+
+在另一个终端:
+
+```bash
+scrcpy --force-adb-forward
+```
+
+
+类似地，对于无线连接，可能需要降低画面质量：
+
+```
+scrcpy -b2M -m800 --max-fps 15
+```
+
+### 窗口设置
+
+#### 标题
+
+窗口的标题默认为设备型号。可以通过如下命令修改：
+
+```bash
+scrcpy --window-title 'My device'
+```
+
+#### 位置和大小
+
+您可以指定初始的窗口位置和大小：
+
+```bash
+scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
+```
+
+#### 无边框
+
+禁用窗口边框：
+
+```bash
+scrcpy --window-borderless
+```
+
+#### 保持窗口在最前
+
+您可以通过如下命令保持窗口在最前面：
+
+```bash
+scrcpy --always-on-top
+```
+
+#### 全屏
+
+您可以通过如下命令直接全屏启动 scrcpy：
+
+```bash
+scrcpy --fullscreen
+scrcpy -f  # 简写
+```
+
+全屏状态可以通过 <kbd>MOD</kbd>+<kbd>f</kbd> 随时切换。
+
+#### 旋转
+
+可以通过以下命令旋转窗口：
+
+```bash
+scrcpy --rotation 1
+```
+
+可选的值有：
+ - `0`: 无旋转
+ - `1`: 逆时针旋转 90°
+ - `2`: 旋转 180°
+ - `3`: 顺时针旋转 90°
+
+也可以使用 <kbd>MOD</kbd>+<kbd>←</kbd> _(左箭头)_ 和 <kbd>MOD</kbd>+<kbd>→</kbd> _(右箭头)_ 随时更改。
+
+需要注意的是， _scrcpy_ 中有三类旋转方向：
+ - <kbd>MOD</kbd>+<kbd>r</kbd> 请求设备在竖屏和横屏之间切换 (如果前台应用程序不支持请求的朝向，可能会拒绝该请求)。
+ - [`--lock-video-orientation`](#锁定屏幕方向) 改变镜像的朝向 (设备传输到电脑的画面的朝向)。这会影响录制。
+ - `--rotation` (或 <kbd>MOD</kbd>+<kbd>←</kbd>/<kbd>MOD</kbd>+<kbd>→</kbd>) 只旋转窗口的内容。这只影响显示，不影响录制。
+
+
+### 其他镜像设置
+
+#### 只读
+
+禁用电脑对设备的控制 (任何可与设备交互的方式：如键盘输入、鼠标事件和文件拖放)：
+
+```bash
+scrcpy --no-control
+scrcpy -n
+```
+
+#### 显示屏
+
+如果设备有多个显示屏，可以选择要镜像的显示屏：
+
+```bash
+scrcpy --display 1
+```
+
+可以通过如下命令列出所有显示屏的 id：
+
+```
+adb shell dumpsys display   # 在输出中搜索 “mDisplayId=”
+```
+
+控制第二显示屏需要设备运行 Android 10 或更高版本 (否则将在只读状态下镜像)。
+
+
+#### 保持常亮
+
+阻止设备在连接时一段时间后休眠：
+
+```bash
+scrcpy --stay-awake
+scrcpy -w
+```
+
+scrcpy 关闭时会恢复设备原来的设置。
+
+
+#### 关闭设备屏幕
+
+可以通过以下的命令行参数在关闭设备屏幕的状态下进行镜像：
+
+```bash
+scrcpy --turn-screen-off
+scrcpy -S
+```
+
+或者在任何时候按 <kbd>MOD</kbd>+<kbd>o</kbd>。
+
+要重新打开屏幕，按下 <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>o</kbd>。
+
+在Android上，`电源` 按钮始终能把屏幕打开。为了方便，对于在 _scrcpy_ 中发出的 `电源` 事件 (通过鼠标右键或 <kbd>MOD</kbd>+<kbd>p</kbd>)，会 (尽最大的努力) 在短暂的延迟后将屏幕关闭。设备上的 `电源` 按钮仍然能打开设备屏幕。
+
+还可以同时阻止设备休眠：
+
+```bash
+scrcpy --turn-screen-off --stay-awake
+scrcpy -Sw
+```
+
+#### 退出时息屏
+
+scrcpy 退出时关闭设备屏幕：
+
+```bash
+scrcpy --power-off-on-close
+```
+
+#### 显示触摸
+
+在演示时，可能会需要显示 (在物理设备上的) 物理触摸点。
+
+Android 在 _开发者选项_ 中提供了这项功能。
+
+_Scrcpy_ 提供一个选项可以在启动时开启这项功能并在退出时恢复初始设置：
+
+```bash
+scrcpy --show-touches
+scrcpy -t
+```
+
+请注意这项功能只能显示 _物理_ 触摸 (用手指在屏幕上的触摸)。
+
+
+#### 关闭屏保
+
+_Scrcpy_ 默认不会阻止电脑上开启的屏幕保护。
+
+关闭屏幕保护：
+
+```bash
+scrcpy --disable-screensaver
+```
+
+
+### 输入控制
+
+#### 旋转设备屏幕
+
+使用 <kbd>MOD</kbd>+<kbd>r</kbd> 在竖屏和横屏模式之间切换。
+
+需要注意的是，只有在前台应用程序支持所要求的模式时，才会进行切换。
+
+#### 复制粘贴
+
+每次安卓的剪贴板变化时，其内容都会被自动同步到电脑的剪贴板上。
+
+所有的 <kbd>Ctrl</kbd> 快捷键都会被转发至设备。其中：
+ - <kbd>Ctrl</kbd>+<kbd>c</kbd> 通常执行复制
+ - <kbd>Ctrl</kbd>+<kbd>x</kbd> 通常执行剪切
+ - <kbd>Ctrl</kbd>+<kbd>v</kbd> 通常执行粘贴 (在电脑到设备的剪贴板同步完成之后)
+
+大多数时候这些按键都会执行以上的功能。
+
+但实际的行为取决于设备上的前台程序。例如，_Termux_ 会在按下 <kbd>Ctrl</kbd>+<kbd>c</kbd> 时发送 SIGINT，又如 _K-9 Mail_ 会新建一封邮件。
+
+要在这种情况下进行剪切，复制和粘贴 (仅支持 Android >= 7)：
+ - <kbd>MOD</kbd>+<kbd>c</kbd> 注入 `COPY` (复制)
+ - <kbd>MOD</kbd>+<kbd>x</kbd> 注入 `CUT` (剪切)
+ - <kbd>MOD</kbd>+<kbd>v</kbd> 注入 `PASTE` (粘贴) (在电脑到设备的剪贴板同步完成之后)
+
+另外，<kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd> 会将电脑的剪贴板内容转换为一串按键事件输入到设备。在应用程序不接受粘贴时 (比如 _Termux_)，这项功能可以派上一定的用场。不过这项功能可能会导致非 ASCII 编码的内容出现错误。
+
+**警告：** 将电脑剪贴板的内容粘贴至设备 (无论是通过 <kbd>Ctrl</kbd>+<kbd>v</kbd> 还是 <kbd>MOD</kbd>+<kbd>v</kbd>) 都会将内容复制到设备的剪贴板。如此，任何安卓应用程序都能读取到。您应避免将敏感内容 (如密码) 通过这种方式粘贴。
+
+一些设备不支持通过程序设置剪贴板。通过 `--legacy-paste` 选项可以修改 <kbd>Ctrl</kbd>+<kbd>v</kbd> 和 <kbd>MOD</kbd>+<kbd>v</kbd> 的工作方式，使它们通过按键事件 (同 <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd>) 来注入电脑剪贴板内容。
+
+#### 双指缩放
+
+模拟“双指缩放”：<kbd>Ctrl</kbd>+_按住并移动鼠标_。
+
+更准确的说，在按住鼠标左键时按住 <kbd>Ctrl</kbd>。直到松开鼠标左键，所有鼠标移动将以屏幕中心为原点，缩放或旋转内容 (如果应用支持)。
+
+实际上，_scrcpy_ 会在关于屏幕中心对称的位置上用“虚拟手指”发出触摸事件。
+
+#### 物理键盘模拟 (HID)
+
+默认情况下，scrcpy 使用安卓按键或文本注入，这在任何情况都可以使用，但仅限于ASCII字符。
+
+在 Linux 上，scrcpy 可以模拟为 Android 上的物理 USB 键盘，以提供更好地输入体验 (使用 [USB HID over AOAv2][hid-aoav2])：禁用虚拟键盘，并适用于任何字符和输入法。
+
+[hid-aoav2]: https://source.android.com/devices/accessories/aoa2#hid-support
+
+不过，这种方法仅支持 USB 连接以及 Linux平台。
+
+启用 HID 模式：
+
+```bash
+scrcpy --hid-keyboard
+scrcpy -K  # 简写
+```
+
+如果失败了 (如设备未通过 USB 连接)，则自动回退至默认模式 (终端中会输出日志)。这即允许通过 USB 和 TCP/IP 连接时使用相同的命令行参数。
+
+在这种模式下，原始按键事件 (扫描码) 被发送给设备，而与宿主机按键映射无关。因此，若键盘布局不匹配，需要在 Android 设备上进行配置，具体为 设置 → 系统 → 语言和输入法 → [实体键盘]。
+
+[Physical keyboard]: https://github.com/Genymobile/scrcpy/pull/2632#issuecomment-923756915
+
+#### 文本注入偏好
+
+打字的时候，系统会产生两种[事件][textevents]：
+ - _按键事件_ ，代表一个按键被按下或松开。
+ - _文本事件_ ，代表一个字符被输入。
+
+程序默认使用按键事件来输入字母。只有这样，键盘才会在游戏中正常运作 (例如 WASD 键)。
+
+但这也有可能[造成一些问题][prefertext]。如果您遇到了问题，可以通过以下方式避免：
+
+```bash
+scrcpy --prefer-text
+```
+
+(这会导致键盘在游戏中工作不正常)
+
+该选项不影响 HID 键盘 (该模式下，所有按键都发送为扫描码)。
+
+[textevents]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-text-input
+[prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343
+
+
+#### 按键重复
+
+默认状态下，按住一个按键不放会生成多个重复按键事件。在某些游戏中这通常没有实际用途，且可能会导致性能问题。
+
+避免转发重复按键事件：
+
+```bash
+scrcpy --no-key-repeat
+```
+
+该选项不影响 HID 键盘 (该模式下，按键重复由 Android 直接管理)。
+
+#### 右键和中键
+
+默认状态下，右键会触发返回键 (或电源键开启)，中键会触发 HOME 键。要禁用这些快捷键并把所有点击转发到设备：
+
+```bash
+scrcpy --forward-all-clicks
+```
+
+
+### 文件拖放
+
+#### 安装APK
+
+将 APK 文件 (文件名以 `.apk` 结尾) 拖放到 _scrcpy_ 窗口来安装。
+
+不会有视觉反馈，终端会输出一条日志。
+
+
+#### 将文件推送至设备
+
+要推送文件到设备的 `/sdcard/Download/`，将 (非 APK) 文件拖放至 _scrcpy_ 窗口。
+
+不会有视觉反馈，终端会输出一条日志。
+
+在启动时可以修改目标目录：
+
+```bash
+scrcpy --push-target=/sdcard/Movies/
+```
+
+
+### 音频转发
+
+_Scrcpy_ 不支持音频。请使用 [sndcpy]。
+
+另见 [issue #14]。
+
+[sndcpy]: https://github.com/rom1v/sndcpy
+[issue #14]: https://github.com/Genymobile/scrcpy/issues/14
+
+
+## 快捷键
+
+在以下列表中, <kbd>MOD</kbd> 是快捷键的修饰键。
+默认是 (左) <kbd>Alt</kbd> 或 (左) <kbd>Super</kbd>。
+
+您可以使用 `--shortcut-mod` 来修改。可选的按键有 `lctrl`、`rctrl`、`lalt`、`ralt`、`lsuper` 和 `rsuper`。例如：
+
+```bash
+# 使用右 Ctrl 键
+scrcpy --shortcut-mod=rctrl
+
+# 使用左 Ctrl 键 + 左 Alt 键，或 Super 键
+scrcpy --shortcut-mod=lctrl+lalt,lsuper
+```
+
+_<kbd>[Super]</kbd> 键通常是指 <kbd>Windows</kbd> 或 <kbd>Cmd</kbd> 键。_
+
+[Super]: https://en.wikipedia.org/wiki/Super_key_(keyboard_button)

+
+
+## 自定义路径
+
+要使用指定的 _adb_ 二进制文件，可以设置环境变量 `ADB`：
+
+```bash
+ADB=/path/to/adb scrcpy
+```
+
+要覆盖 `scrcpy-server` 的路径，可以设置 `SCRCPY_SERVER_PATH`。
+
+要覆盖图标，可以设置其路径至 `SCRCPY_ICON_PATH`。
+
+
+## 为什么叫 _scrcpy_ ？
+
+一个同事让我找出一个和 [gnirehtet] 一样难以发音的名字。
+
+[`strcpy`] 复制一个 **str**ing （字符串）； `scrcpy` 复制一个 **scr**een （屏幕）。

+# scrcpy (v1.15)
+
+Scrcpy 可以透過 USB、或是 [TCP/IP][article-tcpip] 來顯示或控制 Android 裝置。且 scrcpy 不需要 _root_ 權限。
+
+Scrcpy 目前支援 _GNU/Linux_、_Windows_ 和 _macOS_。
+
+![screenshot](assets/screenshot-debian-600.jpg)
+
+特色:
+
+ - **輕量** (只顯示裝置螢幕)
+ - **效能** (30~60fps)
+ - **品質** (1920×1080 或更高)
+ - **低延遲** ([35~70ms][lowlatency])
+ - **快速啟動** (~1 秒就可以顯示第一個畫面)
+ - **非侵入性** (不安裝、留下任何東西在裝置上)
+
+[lowlatency]: https://github.com/Genymobile/scrcpy/pull/646
+
+
+## 需求
+
+Android 裝置必須是 API 21+ (Android 5.0+)。

+[Scoop] 上也可以下載:
+
+```bash
+scoop install scrcpy
+scoop install adb    # 如果你還沒有安裝的話
+```
+
+[Scoop]: https://scoop.sh
+
+你也可以自己[編譯 _Scrcpy_][BUILD]。
+
+
+### macOS
+
+_Scrcpy_ 可以在 [Homebrew] 上直接安裝:
+
+[Homebrew]: https://brew.sh/
+
+```bash
+brew install scrcpy
+```
+
+由於執行期間需要可以藉由 `PATH` 存取 `adb` 。如果還沒有安裝 `adb` 可以使用下列方式安裝:
+
+```bash
+brew cask install android-platform-tools
+```
+
+你也可以自己[編譯 _Scrcpy_][BUILD]。
+
+
+## 執行
+
+將電腦和你的 Android 裝置連線，然後執行:
+
+```bash
+scrcpy
+```
+
+_Scrcpy_ 可以接受命令列參數。輸入下列指令就可以瀏覽可以使用的命令列參數:
+
+```bash
+scrcpy --help
+```
+
+
+## 功能
+
+> 以下說明中，有關快捷鍵的說明可能會出現 <kbd>MOD</kbd> 按鈕。相關說明請參見[快捷鍵]內的說明。
+
+[快捷鍵]: #快捷鍵
+
+### 畫面擷取
+
+#### 縮小尺寸
+
+使用比較低的解析度來投放 Android 裝置在某些情況可以提升效能。
+
+限制寬和高的最大值(例如: 1024):
+
+```bash
+scrcpy --max-size 1024
+scrcpy -m 1024  # 縮短版本
+```
+
+比較小的參數會根據螢幕比例重新計算。
+根據上面的範例，1920x1080 會被縮小成 1024x576。
+
+
+#### 更改 bit-rate
+
+預設的 bit-rate 是 8 Mbps。如果要更改 bit-rate (例如: 2 Mbps):
+
+```bash
+scrcpy --bit-rate 2M
+scrcpy -b 2M  # 縮短版本
+```
+
+#### 限制 FPS
+
+限制畫面最高的 FPS:
+
+```bash
+scrcpy --max-fps 15
+```
+
+僅在 Android 10 後正式支援，不過也有可能可以在 Android 10 以前的版本使用。
+
+#### 裁切
+
+裝置的螢幕可以裁切。如此一來，鏡像出來的螢幕就只會是原本的一部份。
+
+假如只要鏡像 Oculus Go 的其中一隻眼睛:
+
+```bash
+scrcpy --crop 1224:1440:0:0   # 位於 (0,0)，大小1224x1440
+```
+
+如果 `--max-size` 也有指定的話，裁切後才會縮放。
+
+
+#### 鎖定影像方向
+
+
+如果要鎖定鏡像影像方向:
+
+```bash
+scrcpy --lock-video-orientation 0   # 原本的方向
+scrcpy --lock-video-orientation 1   # 逆轉 90°
+scrcpy --lock-video-orientation 2   # 180°
+scrcpy --lock-video-orientation 3   # 順轉 90°
+```
+
+這會影響錄影結果的影像方向。
+
+
+### 錄影
+
+鏡像投放螢幕的同時也可以錄影:
+
+```bash
+scrcpy --record file.mp4
+scrcpy -r file.mkv
+```
+
+如果只要錄影，不要投放螢幕鏡像的話:
+
+```bash
+scrcpy --no-display --record file.mp4
+scrcpy -Nr file.mkv
+# 用 Ctrl+C 停止錄影
+```
+
+就算有些幀為了效能而被跳過，它們還是一樣會被錄製。
+
+裝置上的每一幀都有時間戳記，所以 [封包延遲 (Packet Delay Variation, PDV)][packet delay variation] 並不會影響錄影的檔案。
+
+[packet delay variation]: https://en.wikipedia.org/wiki/Packet_delay_variation
+
+
+### 連線
+
+#### 無線
+
+_Scrcpy_ 利用 `adb` 和裝置通訊，而 `adb` 可以[透過 TCP/IP 連結][connect]:
+
+1. 讓電腦和裝置連到同一個 Wi-Fi。
+2. 獲取手機的 IP 位址(設定 → 關於手機 → 狀態).
+3. 啟用裝置上的 `adb over TCP/IP`: `adb tcpip 5555`.
+4. 拔掉裝置上的線。
+5. 透過 TCP/IP 連接裝置: `adb connect DEVICE_IP:5555` _(把 `DEVICE_IP` 換成裝置的IP位址)_.
+6. 和平常一樣執行 `scrcpy`。
+
+如果效能太差，可以降低 bit-rate 和解析度:
+
+```bash
+scrcpy --bit-rate 2M --max-size 800
+scrcpy -b2M -m800  # 縮短版本
+```
+
+[connect]: https://developer.android.com/studio/command-line/adb.html#wireless
+
+
+#### 多裝置
+
+如果 `adb devices` 內有多個裝置，則必須附上 _serial_:
+
+```bash
+scrcpy --serial 0123456789abcdef
+scrcpy -s 0123456789abcdef  # 縮短版本
+```
+
+如果裝置是透過 TCP/IP 連線:
+
+```bash
+scrcpy --serial 192.168.0.1:5555
+scrcpy -s 192.168.0.1:5555  # 縮短版本
+```
+
+你可以啟用復數個對應不同裝置的 _scrcpy_。
+
+#### 裝置連結後自動啟動
+
+你可以使用 [AutoAdb]:
+
+```bash
+autoadb scrcpy -s '{}'
+```
+
+[AutoAdb]: https://github.com/rom1v/autoadb
+
+#### SSH tunnel
+
+本地的 `adb` 可以連接到遠端的 `adb` 伺服器(假設兩者使用相同版本的 _adb_ 通訊協定)，以連接到遠端裝置:
+
+```bash
+adb kill-server    # 停止在 Port 5037 的本地 adb 伺服
+ssh -CN -L5037:localhost:5037 -R27183:localhost:27183 your_remote_computer
+# 保持開啟
+```
+
+從另外一個終端機:
+
+```bash
+scrcpy
+```
+
+如果要避免啟用 remote port forwarding，你可以強制它使用 forward connection (注意 `-L` 和 `-R` 的差別):
+
+```bash
+adb kill-server    # 停止在 Port 5037 的本地 adb 伺服
+ssh -CN -L5037:localhost:5037 -L27183:localhost:27183 your_remote_computer
+# 保持開啟
+```
+
+從另外一個終端機:
+
+```bash
+scrcpy --force-adb-forward
+```
+
+
+和無線連接一樣，有時候降低品質會比較好:
+
+```
+scrcpy -b2M -m800 --max-fps 15
+```
+
+### 視窗調整
+
+#### 標題
+
+預設標題是裝置的型號，不過可以透過以下方式修改:
+
+```bash
+scrcpy --window-title 'My device'
+```
+
+#### 位置 & 大小
+
+初始的視窗位置和大小也可以指定:
+
+```bash
+scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
+```
+
+#### 無邊框
+
+如果要停用視窗裝飾:
+
+```bash
+scrcpy --window-borderless
+```
+
+#### 保持最上層
+
+如果要保持 `scrcpy` 的視窗在最上層:
+
+```bash
+scrcpy --always-on-top
+```
+
+#### 全螢幕
+
+這個軟體可以直接在全螢幕模式下起動:
+
+```bash
+scrcpy --fullscreen
+scrcpy -f  # 縮短版本
+```
+
+全螢幕可以使用 <kbd>MOD</kbd>+<kbd>f</kbd> 開關。
+
+#### 旋轉
+
+視窗可以旋轉:
+
+```bash
+scrcpy --rotation 1
+```
+
+可用的數值:
+ - `0`: 不旋轉
+ - `1`: 90 度**逆**轉
+ - `2`: 180 度
+ - `3`: 90 度**順**轉
+
+旋轉方向也可以使用 <kbd>MOD</kbd>+<kbd>←</kbd> _(左方向鍵)_ 和 <kbd>MOD</kbd>+<kbd>→</kbd> _(右方向鍵)_ 調整。
+
+_scrcpy_ 有 3 種不同的旋轉:
+ - <kbd>MOD</kbd>+<kbd>r</kbd> 要求裝置在垂直、水平之間旋轉 (目前運行中的 App 有可能會因為不支援而拒絕)。
+ - `--lock-video-orientation` 修改鏡像的方向 (裝置傳給電腦的影像)。這會影響錄影結果的影像方向。
+ - `--rotation` (或是 <kbd>MOD</kbd>+<kbd>←</kbd> / <kbd>MOD</kbd>+<kbd>→</kbd>) 只旋轉視窗的內容。這只會影響鏡像結果，不會影響錄影結果。
+
+
+### 其他鏡像選項
+
+#### 唯讀
+
+停用所有控制，包含鍵盤輸入、滑鼠事件、拖放檔案:
+
+```bash
+scrcpy --no-control
+scrcpy -n
+```
+
+#### 顯示螢幕
+
+如果裝置有複數個螢幕，可以指定要鏡像哪個螢幕:
+
+```bash
+scrcpy --display 1
+```
+
+可以透過下列指令獲取螢幕 ID:
+
+```
+adb shell dumpsys display   # 找輸出結果中的 "mDisplayId="
+```
+
+第二螢幕只有在 Android 10+ 時可以控制。如果不是 Android 10+，螢幕就會在唯讀狀態下投放。
+
+
+#### 保持清醒
+
+如果要避免裝置在連接狀態下進入睡眠:
+
+```bash
+scrcpy --stay-awake
+scrcpy -w
+```
+
+_scrcpy_ 關閉後就會回復成原本的設定。
+
+
+#### 關閉螢幕
+
+鏡像開始時，可以要求裝置關閉螢幕:
+
+```bash
+scrcpy --turn-screen-off
+scrcpy -S
+```
+
+或是在任何時候輸入 <kbd>MOD</kbd>+<kbd>o</kbd>。
+
+如果要開啟螢幕，輸入 <kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>o</kbd>。
+
+在 Android 上，`POWER` 按鈕總是開啟螢幕。
+
+為了方便，如果 `POWER` 是透過 scrcpy 轉送 (右鍵 或 <kbd>MOD</kbd>+<kbd>p</kbd>)的話，螢幕將會在短暫的延遲後關閉。
+
+實際在手機上的 `POWER` 還是會開啟螢幕。
+
+防止裝置進入睡眠狀態:
+
+```bash
+scrcpy --turn-screen-off --stay-awake
+scrcpy -Sw
+```
+
+
+#### 顯示過期的幀
+
+為了降低延遲， _scrcpy_ 預設只會顯示最後解碼的幀，並且拋棄所有在這之前的幀。
+
+如果要強制顯示所有的幀 (有可能會拉高延遲)，輸入:
+
+```bash
+scrcpy --render-expired-frames
+```
+
+#### 顯示觸控點
+
+對於要報告的人來說，顯示裝置上的實際觸控點有時候是有幫助的。
+
+Android 在_開發者選項_中有提供這個功能。
+
+_Scrcpy_ 可以在啟動時啟用這個功能，並且在停止後恢復成原本的設定:
+
+```bash
+scrcpy --show-touches
+scrcpy -t
+```
+
+這個選項只會顯示**實際觸碰在裝置上的觸碰點**。
+
+
+### 輸入控制
+
+
+#### 旋轉裝置螢幕
+
+輸入 <kbd>MOD</kbd>+<kbd>r</kbd> 以在垂直、水平之間切換。
+
+如果使用中的程式不支援，則不會切換。
+
+
+#### 複製/貼上
+
+如果 Android 剪貼簿上的內容有任何更動，電腦的剪貼簿也會一起更動。
+
+任何與 <kbd>Ctrl</kbd> 相關的快捷鍵事件都會轉送到裝置上。特別來說:
+ - <kbd>Ctrl</kbd>+<kbd>c</kbd> 通常是複製
+ - <kbd>Ctrl</kbd>+<kbd>x</kbd> 通常是剪下
+ - <kbd>Ctrl</kbd>+<kbd>v</kbd> 通常是貼上 (在電腦的剪貼簿與裝置上的剪貼簿同步之後)
+
+這些跟你通常預期的行為一樣。
+
+但是，實際上的行為是根據目前運行中的應用程式而定。
+
+舉例來說， _Termux_ 在收到 <kbd>Ctrl</kbd>+<kbd>c</kbd> 後，會傳送 SIGINT；而 _K-9 Mail_ 則是建立新訊息。
+
+如果在這情況下，要剪下、複製或貼上 (只有在Android 7+時才支援):
+ - <kbd>MOD</kbd>+<kbd>c</kbd> 注入 `複製`
+ - <kbd>MOD</kbd>+<kbd>x</kbd> 注入 `剪下`
+ - <kbd>MOD</kbd>+<kbd>v</kbd> 注入 `貼上` (在電腦的剪貼簿與裝置上的剪貼簿同步之後)
+
+另外，<kbd>MOD</kbd>+<kbd>Shift</kbd>+<kbd>v</kbd> 則是以一連串的按鍵事件貼上電腦剪貼簿中的內容。當元件不允許文字貼上 (例如 _Termux_) 時，這就很有用。不過，這在非 ASCII 內容上就無法使用。
+
+**警告:** 貼上電腦的剪貼簿內容 (無論是從 <kbd>Ctrl</kbd>+<kbd>v</kbd> 或 <kbd>MOD</kbd>+<kbd>v</kbd>) 時，會複製剪貼簿中的內容至裝置的剪貼簿上。這會讓所有 Android 程式讀取剪貼簿的內容。請避免貼上任何敏感內容 (像是密碼)。
+
+
+#### 文字輸入偏好
+
+輸入文字時，有兩種[事件][textevents]會被觸發:
+ - _鍵盤事件 (key events)_，代表有一個按鍵被按下或放開
+ - _文字事件 (text events)_，代表有一個文字被輸入
+
+預設上，文字是被以鍵盤事件 (key events) 輸入的，所以鍵盤和遊戲內所預期的一樣 (通常是指 WASD)。
+
+但是這可能造成[一些問題][prefertext]。如果在這輸入這方面遇到了問題，你可以試試:
+
+```bash
+scrcpy --prefer-text
+```
+
+(不過遊戲內鍵盤就會不可用)
+
+[textevents]: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-text-input
+[prefertext]: https://github.com/Genymobile/scrcpy/issues/650#issuecomment-512945343
+
+
+#### 重複輸入
+
+通常來說，長時間按住一個按鍵會重複觸發按鍵事件。這會在一些遊戲中造成效能問題，而且這個重複的按鍵事件是沒有意義的。
+
+如果不要轉送這些重複的按鍵事件:
+
+```bash
+scrcpy --no-key-repeat
+```
+
+
+### 檔案
+
+#### 安裝 APK
+
+如果要安裝 APK ，拖放一個 APK 檔案 (以 `.apk` 為副檔名) 到 _scrcpy_ 的視窗上。
+
+視窗上不會有任何反饋；結果會顯示在命令列中。
+
+
+#### 推送檔案至裝置
+
+如果要推送檔案到裝置上的 `/sdcard/` ，拖放一個非 APK 檔案 (**不**以 `.apk` 為副檔名) 到 _scrcpy_ 的視窗上。
+
+視窗上不會有任何反饋；結果會顯示在命令列中。
+
+推送檔案的目標路徑可以在啟動時指定:
+
+```bash
+scrcpy --push-target /sdcard/foo/bar/
+```
+
+
+### 音訊轉送
+
+_scrcpy_ **不**轉送音訊。請使用 [sndcpy]。另外，參見 [issue #14]。
+
+[sndcpy]: https://github.com/rom1v/sndcpy
+[issue #14]: https://github.com/Genymobile/scrcpy/issues/14
+
+
+## 快捷鍵
+
+在以下的清單中，<kbd>MOD</kbd> 是快捷鍵的特殊按鍵。通常來說，這個按鍵是 (左) <kbd>Alt</kbd> 或是 (左) <kbd>Super</kbd>。
+
+這個是可以使用 `--shortcut-mod` 更改的。可以用的選項有:
+- `lctrl`: 左邊的 <kbd>Ctrl</kbd>
+- `rctrl`: 右邊的 <kbd>Ctrl</kbd>
+- `lalt`: 左邊的 <kbd>Alt</kbd>
+- `ralt`: 右邊的 <kbd>Alt</kbd>
+- `lsuper`: 左邊的 <kbd>Super</kbd>
+- `rsuper`: 右邊的 <kbd>Super</kbd>
+
+```bash
+# 以 右邊的 Ctrl 為快捷鍵特殊按鍵
+scrcpy --shortcut-mod=rctrl
+
+# 以 左邊的 Ctrl 和左邊的 Alt 或是 左邊的 Super 為快捷鍵特殊按鍵
+scrcpy --shortcut-mod=lctrl+lalt,lsuper
+```
+
+_<kbd>[Super]</kbd> 通常是 <kbd>Windows</kbd> 或 <kbd>Cmd</kbd> 鍵。_
+
+[Super]: https://en.wikipedia.org/wiki/Super_key_(keyboard_button)

+_³只支援 Android 7+。_
+
+所有 <kbd>Ctrl</kbd>+_按鍵_ 快捷鍵都會傳送到裝置上，所以它們是由目前運作的應用程式處理的。
+
+
+## 自訂路徑
+
+如果要使用特定的 _adb_ ，將它設定到環境變數中的 `ADB`:
+
+    ADB=/path/to/adb scrcpy
+
+如果要覆寫 `scrcpy-server` 檔案的路徑，則將路徑設定到環境變數中的 `SCRCPY_SERVER_PATH`。

-/**
- * Real-time audio player with configurable latency
- *
- * As input, the player regularly receives AVFrames of decoded audio samples.
- * As output, an SDL callback regularly requests audio samples to be played.
- * In the middle, an audio buffer stores the samples produced but not consumed
- * yet.
- *
- * The goal of the player is to feed the audio output with a latency as low as
- * possible while avoiding buffer underrun (i.e. not being able to provide
- * samples when requested).
- *
- * The player aims to feed the audio output with as little latency as possible
- * while avoiding buffer underrun. To achieve this, it attempts to maintain the
- * average buffering (the number of samples present in the buffer) around a
- * target value. If this target buffering is too low, then buffer underrun will
- * occur frequently. If it is too high, then latency will become unacceptable.
- * This target value is configured using the scrcpy option --audio-buffer.
- *
- * The player cannot adjust the sample input rate (it receives samples produced
- * in real-time) or the sample output rate (it must provide samples as
- * requested by the audio output callback). Therefore, it may only apply
- * compensation by resampling (converting _m_ input samples to _n_ output
- * samples).
- *
- * The compensation itself is applied by libswresample (FFmpeg). It is
- * configured using swr_set_compensation(). An important work for the player
- * is to estimate the compensation value regularly and apply it.
- *
- * The estimated buffering level is the result of averaging the "natural"
- * buffering (samples are produced and consumed by blocks, so it must be
- * smoothed), and making instant adjustments resulting of its own actions
- * (explicit compensation and silence insertion on underflow), which are not
- * smoothed.
- *
- * Buffer underflow events can occur when packets arrive too late. In that case,
- * the player inserts silence. Once the packets finally arrive (late), one
- * strategy could be to drop the samples that were replaced by silence, in
- * order to keep a minimal latency. However, dropping samples in case of buffer
- * underflow is inadvisable, as it would temporarily increase the underflow
- * even more and cause very noticeable audio glitches.
- *
- * Therefore, the player doesn't drop any sample on underflow. The compensation
- * mechanism will absorb the delay introduced by the inserted silence.
