I could not make Ctrl+'+' and Ctrl+'-' work for every keyboard on every
platform.
Instead, use Ctrl+UP and Ctrl+DOWN (like in VLC) to change the volume.
Fixes <https://github.com/Genymobile/scrcpy/issues/103>.
The application is now packaged for Homebrew:

Give instructions to install it from Homebrew for macOS (it's much
easier).
Thanks to @stek29 for the formula ;-)
SDL_CreateTexture() is called both during initialization and on frame
size change.
To avoid inconsistent changes to arguments value, factorize them to a
single function create_texture().
Double-clicks were not sent to the device anymore since the
"double-click on black borders" feature.
When a double click occurs inside the device screen, send the event to
the device normally.
Fixes <https://github.com/Genymobile/scrcpy/issues/97>.
Enabling "show touches" involves the execution of an adb command, which
takes some time.
In order to parallelize, execute the command as soon as possible, but
reap the process only once everything is initialized.
If --show-touches is set, then the option must be disabled on quit.
Since it executes an adb command, it takes some time, so close the
window beforehand so that the close window button does not seem
unresponsive.
On H.264 stream EOF, the eof_reached flag is set, but av_read_frame()
still provides a frame, so check the flag only afterwards.
As a side-effect, it also fixes a memory leak (the very last packet was
not unref).
Since _scrcpy_ also supports `adb forward`, remove the part about `adb
reverse`.
Make explicit that _adb_ is included in the prebuilt application for
Windows (many users manually download the platform-tools for no reason).
Request SDL not to replace the SIGINT and SIGTERM handlers, so that the
process is immediately terminated on Ctrl+C.
This avoids process hanging on Ctrl+C during network calls on
initialization.
Some of them accepted a timeout, but it was not used since
commit 9b056f5091 anymore.
In "adb forward" mode, close the server socket as soon as the client is
connected.
Even if unlikely to be useful, it allows to run several instances of
scrcpy also in "adb forward" mode.
On Windows and MacOS, resizing blocks the event loop, so resizing events
are not triggered:
- <https://bugzilla.libsdl.org/show_bug.cgi?id=2077>
- <https://stackoverflow.com/a/40693139/1987178>
As a workaround, register an event watcher to render the screen from
another thread.
Since the whole event loop is blocked during resizing, the screen
content is not refreshed (on Windows and MacOS) until resizing ends.
"adb reverse" currently does not work over tcpip (i.e. on a device
connected by "adb connect"):
<https://issuetracker.google.com/issues/37066218>
To work around the problem, if the call to "adb reverse" fails, then
fallback to "adb forward", and reverse the client/server roles.
Keep the "adb reverse" mode as the default because it does not involve
connection retries: when using "adb forward", the client must try to
connect successively until the server listens.
Due to the tunnel, every connect() will succeed, so the client must
attempt to read() to detect a connection failure. For this purpose, when
using the "adb forward" mode, the server initially writes a dummy byte,
read by the client.
Fixes <https://github.com/Genymobile/scrcpy/issues/5>.
The serial is needed for many server actions, but this is an
implementation detail, so the caller should not have to provide it on
every call.
Instead, store the serial in the server instance on server_start().
This paves the way to implement the "adb forward" fallback properly.
The SDL mouse wheel event seems inconsistent between horizontal and
vertical scrolling.
> Movements to the left generate negative x values and to the right
> generate positive x values. Movements down (scroll backward) generate
> negative y values and up (scroll forward) generate positive y values.
<https://wiki.libsdl.org/SDL_MouseWheelEvent#Remarks>
Reverse the horizontal.
Fixes <https://github.com/Genymobile/scrcpy/issues/49>.
Document server and client dependencies separately, to avoid unneeded
packages installation when building using the prebuilt server.
Also remove "zip", since it's only used for building a portable version
(which is not documented in README).
The codec only supports dimensions which are multiple of 8.
Thus, when --max-size is specified, the value is always rounded down to
the nearest multiple of 8.
However, it was wrongly assumed that the physical size is always a
multiple of 8. To support such devices, also round down the physical
screen dimensions.
Fixes <https://github.com/Genymobile/scrcpy/issues/39>.
The text input control_event was initially designed for mapping
SDL_TextInputEvent, limited to 32 characters.
For simplicity, the copy/paste feature was implemented using the same
control_event: it just sends the text to paste.
However, the pasted text might have a length breaking some assumptions:
- on the client, the event max-size was smaller than the text
max-length,
- on the server, the raw buffer storing the events was smaller than the
max event size.
Fix these inconsistencies, and encode the length on 2 bytes, to accept
more than 256 characters.
Fixes <https://github.com/Genymobile/scrcpy/issues/10>.
Paste computer clipboard to the device on Ctrl+v.
The other direction (pasting the device clipboard to the computer) is
not implemented. It would require a communication channel from the
device to the computer, other than the socket used by the video stream.
The High DPI support is enabled by default, so that the renderer use the
full definition of High DPI screens.
However, there are still mouse coordinates problems on some MacOS having
High DPI support (but not all), so expose a way to disable it.
The decoder sometimes returned a non-zero value on error, but not on
every path.
Since we never use the value, always return 0 at the end (like in the
controller).
SDL_MouseWheelEvent does not provide the mouse location, so we used
SDL_GetMouseState() to retrieve it.
Unfortunately, SDL_GetMouseState() returns a position expressed in the
window coordinate system while the position filled in SDL events are
expressed in the renderer coordinate system. As a consequence, the
scroll was not applied at the right position on the device.
Therefore, convert the coordinate system.
See <https://stackoverflow.com/questions/49111054/how-to-get-mouse-position-on-mouse-wheel-event>.
Use high DPI if available.
Note that on Mac OS X, setting this flag is not sufficient:
> On Apple's OS X you must set the NSHighResolutionCapable Info.plist
> property to YES, otherwise you will not receive a High DPI OpenGL
> display.

On user request to quit, two kinds of blocking calls must be interrupted
on the server:
1. the reads from and writes to the socket;
2. the call to MediaCodec.dequeueOutputBuffer().
The former case was handled by calling shutdown() on the socket from the
client, but the latter was not managed.
There is no easy way to wake this call properly, so just terminate the
process from the client (i.e. send SIGTERM on Linux) instead.
The server is copied to /data/local/tmp/scrcpy-server.jar and executed
on the device.
As soon as we are connected, we can unlink (rm) it from /data/local/tmp,
to keep the device clean.
The server is currently a JAR, but it may ba an APK or a DEX, so the
variable name should not contain the type.
Rename the environment variable, the Meson options and the C
definitions.
No exception was thrown on EOF, so the event controller did not
terminate. This leaded to a further InvocationTargetException.
Instead, terminate the event controller on EOF, so that the process
terminates properly.
Expose net_recv_all() and net_send_all(), equivalent of net_recv() and
net_send(), but that waits/retries until the requested length has been
transferred.
Use these new functions where it was (wrongly) assumed that the
requested length had been transferred.
