This aims to fix two issues with the previous implementation:
1. the whole content of downloaded archives were extracted, while only
few files are necessary;
2. the archives were extracted in the prebuild-deps/ directory as is.
As a consequence of (2), the actual directory name relied on the root
directory of the archive. For adb, this root directory was always
"platform-tools", so when bumping the adb version, the target directory
already existed and the dependency was not upgraded (the old one had to
be removed manually).
Expose common function to download a file and check its checksum, but
let the custom script for each dependency extract only the needed files
and reorganize the content if necessary.
Add an option --otg to run scrcpy with only physical keyboard and mouse
simulation (HID over AOA), without mirroring and without requiring adb.
To avoid adding complexity into the scrcpy initialization and screen
implementation, OTG mode is implemented totally separately, with a
separate window.
PR #2974 <https://github.com/Genymobile/scrcpy/pull/2974>
Input events helpers to convert from SDL events to scrcpy events were
implemented in input_manager. To reuse them for OTG mode, move them to
input_events.h.
PR #2974 <https://github.com/Genymobile/scrcpy/pull/2974>
The device disconnection is detected when the video socket closes.
In order to introduce an OTG mode (HID events) without mirroring (and
without server), we must be able to detect USB device disconnection.
This feature will only be used in OTG mode.
PR #2974 <https://github.com/Genymobile/scrcpy/pull/2974>
Acksync is used to delay HID events until some request (in practice,
device clipboard synchronization) is acknowledged by the device.
This mechanism will not be necessary for OTG mode.
PR #2974 <https://github.com/Genymobile/scrcpy/pull/2974>
The device was automatically found by sc_usb_connect(). Instead, expose
a function to find a device from a serial, and let the caller connect to
the device found (if any).
This will allow to list all devices first, then select one device to
connect to.
PR #2974 <https://github.com/Genymobile/scrcpy/pull/2974>
Use it from accept_device() to simplify (at the cost an additional
allocation for each serial, but it is not important).
It will also be useful in other functions in further commits.
PR #2974 <https://github.com/Genymobile/scrcpy/pull/2974>
The server needs to interrupt the sockets on stop, but it must not close
them while other threads may attempt to read from or write to them.
In particular, the video_socket is read by the stream thread, and the
control_socket is written by the controller and read by receiver.
Therefore, close the socket only on sc_server_destroy(), which is called
after all other threads are joined.

On Windows, the file explorer does not provide any "open a terminal
here" shortcut.
Add a bat file which just runs `cmd` to easily open a terminal directly
in the scrcpy directory (so there is no need to `cd C:\path\…`).
PR #2970 <https://github.com/Genymobile/scrcpy/pull/2970>
For convenience, this new option forces the 3 following options:
- send_device_meta=false
- send_frame_meta=false
- send_dummy_byte=false
This allows to send a raw H.264 stream on the video socket.
Concretely:
adb push scrcpy-server /data/local/tmp/scrcpy-server.jar
adb forward tcp:1234 localabstract:scrcpy
adb shell CLASSPATH=/data/local/tmp/scrcpy-server.jar \
app_process / com.genymobile.scrcpy.Server 1.21 \
raw_video_stream=true tunnel_forward=true control=false
As soon as a client connects via TCP to localhost:1234, it will receive
the raw H.264 stream.
Refs #1419 comment <https://github.com/Genymobile/scrcpy/pull/1419#issuecomment-1013964650>
PR #2971 <https://github.com/Genymobile/scrcpy/pull/2971>
Similar to send_device_frame, this option allows to disable sending the
device name and size on start.
This is only useful when using the scrcpy-server alone to get a raw
H.264 stream, without using the scrcpy client.
PR #2971 <https://github.com/Genymobile/scrcpy/pull/2971>
Move the options unused by the scrcpy client at the end.
These options may be useful to use scrcpy-server directly (to get a raw
H.264 stream for example).
PR #2971 <https://github.com/Genymobile/scrcpy/pull/2971>
Retry with a lower definition if MediaCodec fails before the first
frame, not the first packet.
In practice, the first packet is a config packet without any frame, and
MediaCodec might fail just after.
Refs 2eb6fe7d81
Refs #2963 <https://github.com/Genymobile/scrcpy/issues/2963>
If --no-control is requested, then the controller instance is not
initialized. However, its reference was still passed to screen and
input_manager.
Instead, pass NULL if no controller is available.
MediaCodec errors always trigger IllegalStateException or a subtype
(like MediaCodec.CodecException).
In practice, this avoids to retry if the error is caused by an
IOException when writing the video packet to the socket.
The purpose of automatic downscaling on error is to make mirroring work
by just starting scrcpy without an explicit -m value, even if the
encoder could not encode at the screen definition.
It is only useful when we detect an encoding failure before the first
frame. Downsizing later could be surprising, so disable it.
PR #2947 <https://github.com/Genymobile/scrcpy/pull/2947>
The optimal initial size was computed from the expected dimensions, sent
immediately by the server before encoding any video frame.
However, the actual frame size may be different, for example when the
device encoder does not support the requested size.
To always handle this case properly, position and size the window only
once the first frame size is known.
PR #2947 <https://github.com/Genymobile/scrcpy/pull/2947>
Show the window only after the actual frame size is known (and if no
error has occurred).
This will allow to properly position and size the window when the size
of the first frame is different from the size initially announced by the
server.
PR #2947 <https://github.com/Genymobile/scrcpy/pull/2947>
Now that scrcpy attempts with a lower definition on any MediaCodec
error (or the user explicitly requests to disable auto-downsizing), the
suggestion is unnecessary.
PR #2947 <https://github.com/Genymobile/scrcpy/pull/2947>
Some devices are not able to encode at the device screen definition.
Instead of just failing, try with a lower definition on any MediaCodec
error.
PR #2947 <https://github.com/Genymobile/scrcpy/pull/2947>
The FFmpeg dependency is downloaded from two separate zipfiles.
Symlink include/ to expose everything from a single directory, to
simplify the meson script.
PR #2952 <https://github.com/Genymobile/scrcpy/pull/2952>
The fact that the current prebuilt FFmpeg is split into two separate
zipfiles is an implementation detail.
Use a single Makefile recipe for both files.
PR #2952 <https://github.com/Genymobile/scrcpy/pull/2952>
The components should be configurable independently of the global
scrcpy_options instance: their configuration could be provided
separately, like it is the case for example for some screen parameters.
For consistency, keyboard injection should not depend on scrcpy_options.
In relative mouse mode, the mouse pointer must be "captured" from the
computer.
Toggle (disable/enable) relative mouse mode using any of the hardcoded
capture keys:
- left-Alt
- left-Super
- right-Super
These capture keys do not conflict with shortcuts, since a shortcut is
always a combination of the MOD key and some other key, while the
capture key triggers an action only if it is pressed and released alone.
The relative mouse mode is also automatically enabled on any click in
the window, and automatically disabled on focus lost (it is possible to
lose focus even without the mouse).
