Audio PTS are retrieved by AudioRecord.getTimestamp(), so they do not
necessarily exactly match the number of samples (this allows to take
drift and lag into account).
As a consequence, two consecutive timestamps in microseconds may
sometimes end up within the same millisecond, causing the warning. This
is particularly true for the Matroska muxer which uses a timebase of
1/1000 (1 ms precision).
Since this is "expected", lower the log level from warning to debug.
If the difference of PTS between two consecutive blocks of audio is less
than 1 sample, then it will be considered as non-increasing by FFmpeg
muxers having a time_base of 1/sample_rate.
Increase the PTS by 1 sample instead.
If several reads are performed for a single captured audio block (e.g.
if the read size is smaller than the captured block), then the provided
timestamp was the same for all packets.
Recompute the timestamp for each of them.
In practice, the system captures audio samples by blocks of 1024
samples.
Remplace the hardcoded value of 5 milliseconds (240 samples), and let
AudioRecord fill the input buffer provided by MediaCodec (or by
AudioRawRecorder), with a maximum size of 1024 samples (just in case).
FLAC is not low latency: the default encoder produces blocks of 4096
samples, which represent ~85.333ms.
Increase the audio buffer by default so that audio playback works.
It is incorret to ever call:
streamer.writeDisableStream(...);
after:
streamer.writeAudioHeader();
Move the try-catch block so that it can never happen.
Some devices may provide invalid ranges, causing an
IllegalArgumentException "lower must be less than or equal to upper".
Catch the exception to list the cameras anyway.

Interrupting async processors may require to shutdown the connection to
wake up blocking calls.
Therefore, shutdown the connection first, then join the threads, then
close the connection.

Add --camera-high-speed to enable high frame rate camera capture. If
the option is enabled, then --camera-fps is mandatory.

Add a new option for specifying the camera frame rate.
By default, Android's default frame rate (30 fps) is used.

In addition to --camera-size to specify an explicit size, make it
possible to select the camera size automatically, respecting the maximum
size (already used for display mirroring) and an aspect ratio.
For example, "scrcpy --video-source=camera" followed by:
- (no additional arguments)
: mirrors at the maximum size, any a-r
- -m1920
: only consider valid sizes having both dimensions not above 1920
- --camera-ar=4:3
: only consider valid sizes having an aspect ratio of 4:3 (+/- 10%)
- -m2048 --camera-ar=1.6
: only consider valid sizes having both dimensions not above 2048
and an aspect ratio of 1.6 (+/- 10%)

Add an option to select the camera by its lens facing (front, back or
external).

If --audio-source is not specified, select the default value
according to the video source:
- for display mirroring, use device audio by default;
- for camera mirroring, use microphone by default.

Extract an interface SurfaceCapture from ScreenEncoder, representing a
video source which can be rendered to a Surface for encoding.
Split ScreenEncoder into:
- ScreenCapture, implementing SurfaceCapture to capture the device
screen,
- SurfaceEncoder, to encode any SurfaceCapture.
This separation prepares the introduction of another SurfaceCapture
implementation to capture the camera instead of the device screen.
