The HID ids (accessory ids or UHID ids) were defined by the keyboard and
mouse implementations.
Instead, define them in the common HID part, and make that id part of
the sc_hid_event.
This prepares the introduction of gamepad support, which will handle
several gamepads (and ids) in the common HID gamepad code.
PR #5270 <https://github.com/Genymobile/scrcpy/pull/5270>
Control messages are queued from the main thread and sent to the device
from a separate thread.
When the queue is full, messages are just dropped. This avoids to
accumulate too much delay between the client and the device in case of
network issue.
However, some messages should not be dropped: for example, dropping a
UHID_CREATE message would make all further UHID_INPUT messages invalid.
Therefore, mark these messages as non-droppable.
A non-droppable event is queued anyway (resizing the queue if
necessary, unless the allocation fails).

This allows to schedule a runnable to be executed on the main thread,
until the event loop is explicitly terminated.
It is guaranteed that all accepted runnables will be executed (this
avoids possible memory leaks if a runnable owns resources).
PR #5270 <https://github.com/Genymobile/scrcpy/pull/5270>
It is better to disable Nagle's algorithm to avoid unnecessary latency
for control messages. (I'm not sure this has any impact for a local TCP
socket though.)
Many parsing and formatting C functions like strtof() and asprintf() are
locale-dependent. Forcing a C locale just for the conversions in a way
that works on all platforms is a mess.
In practice, this is not a problem, scrcpy always uses the C locale,
because it never calls:
setlocale(LC_ALL, "");
But the max-fps option should not depend on the locale configuration
anyway.
Since the value is parsed by the client in Java anyway, just forward the
string value as is.
Android accepts a float value, there is no reason to limit the option
to be an integer.
In particular, it allows to capture at a rate lower than 1 fps. For
example, to capture 1 frame every 5 seconds:
scrcpy --video-source=camera --max-fps=0.2
It was already possible to pass a float manually:
scrcpy --video-source=camera \
--video-codec-options=max-fps-to-encoder:float=0.2
But accepting a float directly for --max-fps is more convenient.

A video width or height of 0 triggered an assert.
Fail explicitly instead: the server may actually send this size in
practice (for example on cropping with small dimensions, even if the
requested crop size is not 0).
The delay buffer clock estimates the clock offset between the PTS and
the frame decoded date using an "Exponentially Weighted Moving Average"
(EWMA).
But for the first frames, the clock have less than SC_CLOCK_RANGE
points to average. Since the timing for the first frames are typically
the worst ones, give more weight to the last point for the estimation.
Once SC_CLOCK_RANGE points are available (i.e. when SC_CLOCK_RANGE ==
clock->range), the new estimation is equivalent to the previous version.
The delay buffer `stopped` field was not initialized.
Since it practice the unique instance of sc_delay_buffer is initialized
in static memory, the flag was initialized to false as a side effect.
But with commit fd0f432e87, in debug mode
only, the delay buffer was broken.
"Could not" implies that the system tried to disable the option but
encountered an issue or failure.
"Cannot" indicates a rule or restriction, meaning it's not possible to
perform the action at all.
By default, the audio source is initialized to SC_AUDIO_SOURCE_AUTO, and
is "resolved" only if audio is enabled.
But the server arguments were built assuming that the audio source was
never SC_AUDIO_SOURCE_AUTO (even with audio disabled), causing a crash.
Regression introduced by a10f8cd798.
Automatically switch implicit audio source to "playback" if --audio-dup
is passed.
This allows to run:
scrcpy --audio-dup
without specifying explicitly:
scrcpy --audio-source=playback --audio-dup
PR #5102 <https://github.com/Genymobile/scrcpy/pull/5102>
Add a new method to capture audio playback.
It requires Android 13 (where the Shell app has MODIFY_AUDIO_ROUTING
permission).
The main benefit is that it supports keeping audio playing on the device
(implemented in a further commit).

Passing an unknown enum value to convert them to string would return
NULL without any error, possibly causing undefined behavior later.
Add assertions to catch such programming errors early.
Add secondary bindings (Shift+click) for mouse buttons.
In addition to:
--mouse-bind=xxxx
It is now possible to pass a sequence of secondary bindings:
--mouse-bind=xxxx:xxxx
<--> <-->
primary secondary
bindings bindings
If the second sequence is omitted, then it is the same as the first one.
By default, for SDK mouse, primary bindings trigger shortcuts and
secondary bindings forward all clicks.
For AOA and UHID, the default bindings are reversed: all clicks are
forwarded by default, whereas pressing Shift+click trigger shortcuts.
--mouse-bind=bhsn:++++ # default for SDK
--mouse-bind=++++:bhsn # default for AOA and UHID

PR #5076 <https://github.com/Genymobile/scrcpy/pull/5076>
The buttons state was tracked by SDL_GetMouseState(), and scrcpy applied
a mask to ignore buttons used for shortcuts.
Instead, track the buttons actually pressed (ignoring shortcuts)
manually, to prepare the introduction of more dynamic mouse shortcuts.

For pinch-to-zoom, rotation and tilt simulation, always use a finger
source (instead of a mouse) for both pointers (the real one and the
simulated one).
A "virtual" mouse does not work on all devices (e.g. on Pixel 8).
PR #5076 <https://github.com/Genymobile/scrcpy/pull/5076>
A device disconnection (when the adb connection is closed) makes the
read() on the "receiver" socket fail.
Since commit 063a8339ed, this is reported
as an error. As a consequence, scrcpy fails with:
ERROR: Controller error
instead of:
WARN: Device disconnected
To fix the issue, report a device disconnection in that case.

This also avoids a warning with some compilers which do not understand
that the condition to initialize the variable is the same as the
condition to use it:
../app/src/scrcpy.c: In function ‘scrcpy’:
../app/src/scrcpy.c:750:13: warning: ‘src’ may be used uninitialized in this function [-Wmaybe-uninitialized]
750 | sc_frame_source_add_sink(src, &s->screen.frame_sink);
