e89e772c7c Remove unnecessary 'else'
Some server parameters may depend on one another. For example,
audio_bit_rate is meaningless if audio is false.

But it is inconsistent to disable some parameters based on these
dependencies checks, but not others. Handling all dependencies between
parameters would add too much complexity for no benefit.

So just pass individual parameters independently.

c083a7cc90 Force OpenGL Core Profile context on macOS
By default, SDL creates an OpenGL 2.1 context on macOS for an OpenGL
renderer. As a consequence, mipmapping is not supported.

Force to use a core profile context, to get a higher version.

Before:

    INFO: Renderer: opengl
    INFO: OpenGL version: 2.1 NVIDIA-14.0.32 355.11.11.10.10.143
    WARN: Trilinear filtering disabled (OpenGL 3.0+ or ES 2.0+ required)

After:

    INFO: Renderer: opengl
    DEBUG: Creating OpenGL Core Profile context
    INFO: OpenGL version: 4.1 NVIDIA-14.0.32 355.11.11.10.10.143
    INFO: Trilinear filtering enabled

when running with:

    scrcpy --verbosity=debug --render-driver=opengl

Note: Since SDL_CreateRenderer() causes a fallback to OpenGL 2.1, the
profile and version attributes have to be set and the context created
_after_.

669e9a8d1e Fix "ip route" parsing
If a line did not end with '\r', then the final `\n' was replaced by
'\0' for parsing the current line. This `\0` was then mistakenly
considered as the end of the whole "ip route" output, so the remaining
lines were not parsed, causing "scrcpy --tcpip" to fail in some cases.

To fix the issue, read the final character of the current line before it
is (possibly) overwritten by '\0'.

2f9396e24a Simplify clock estimation
The slope encodes the drift between the device clock and the computer
clock. Its real value is expected very close to 1.

To estimate it, just assume it is exactly 1.

Since the clock is used to estimate very close points in the future, the
error caused by clock drift is totally negligible, and in practice it is
way lower than the slope estimation error.

Therefore, only estimate the offset.

39544f34b4 Add --audio-output-buffer
On some systems, the SDL audio callback is not called frequently enough
(for example it requests 5ms of samples every 10ms), because the output
buffer is too small.

By default, we want to use a small value (5ms) to minimize latency and
buffer underrun, but if it does not work well, users need a way to
increase it.

6b769675fa Fix an "expected expression" error
In C, a label can only be followed by a statement, not a declaration.
An error in `app/src/screen.c` violated this, and led to a build error
with an error message similar to the one below:

    ../app/src/screen.c:821:13: error: expected expression
                bool ok = sc_screen_init_size(screen);
                ^
    /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/13.0.0/include/stdbool.h:15:14: note: expanded from macro 'bool'
    #define bool _Bool
                 ^
    ../app/src/screen.c:822:18: error: use of undeclared identifier 'ok'
                if (!ok) {
                     ^
    2 errors generated.

This could be fixed by introducing a new block (or compound statement;
as is already being done in the next `case`). That is a statement.

238ab872ba Pass video size as codec metadata
On initial connection, scrcpy sent some device metadata:
 - the device name (to be used as window title)
 - the initial video size (before any frame or even SPS/PPS)

But it is better to provide the initial video size as part as the video
stream, so that it can be demuxed and exposed via AVCodecContext to
sinks.

This avoids to pass an explicit "initial frame size" for the screen, the
recorder and the v4l2 sink.

5052e15f7f Create recorder streams from packet sinks ops
Previously, the packet sink push() implementation just set the codec and
notified a wait condition. Then the recorder thread read the codec and
created the AVStream.

But this was racy: an AVFrame could be pushed before the creation of the
AVStream, causing its video_stream_index or audio_stream_index to be
initialized to -1.

Also, in the future, the AVStream initialization might need data
provided by the packet sink open(), so initialize it there (with a
mutex).
