Fix audio player comment

Increase buffering level smoothness
The buffering level does not change continuously: it increases abruptly when a packet is received, and decreases abruptly when an audio block is consumed. To estimate the buffering level, a rolling average is used. To make the buffering more stable, increase the smoothness of this rolling average. This decreases the risk of enabling audio compensation due to an estimation error.

- - [Windows](doc/windows.md) (read [how to run](doc/windows.md#run))
+ - [Windows](doc/windows.md)
 - [macOS](doc/macos.md)
 ## Must-know tips
 - [Reducing resolution](doc/video.md#size) may greatly improve performance
   (`scrcpy -m1024`)
 - [_Right-click_](doc/mouse.md#mouse-bindings) triggers `BACK`
 - [_Middle-click_](doc/mouse.md#mouse-bindings) triggers `HOME`

 - There are many other [shortcuts](doc/shortcuts.md)
 ## Usage examples
 There are a lot of options, [documented](#user-documentation) in separate pages.
 Here are just some common examples.
 - Capture the screen in H.265 (better quality), limit the size to 1920, limit
   the frame rate to 60fps, disable audio, and control the device by simulating
   a physical keyboard:
    ```bash
    scrcpy --video-codec=h265 --max-size=1920 --max-fps=60 --no-audio --keyboard=uhid
    scrcpy --video-codec=h265 -m1920 --max-fps=60 --no-audio -K  # short version
    ```
 - Start VLC in a new virtual display (separate from the device display):
    ```bash
    scrcpy --new-display=1920x1080 --start-app=org.videolan.vlc
    ```
 - Record the device camera in H.265 at 1920x1080 (and microphone) to an MP4
   file:
    ```bash
    scrcpy --video-source=camera --video-codec=h265 --camera-size=1920x1080 --record=file.mp4
    ```
 - Capture the device front camera and expose it as a webcam on the computer (on
   Linux):
    ```bash
    scrcpy --video-source=camera --camera-size=1920x1080 --camera-facing=front --v4l2-sink=/dev/video2 --no-playback
    ```
 - Control the device without mirroring by simulating a physical keyboard and
   mouse (USB debugging not required):
    ```bash
    scrcpy --otg
    ```
 - Control the device using gamepad controllers plugged into the computer:
    ```bash
    scrcpy --gamepad=uhid
    scrcpy -G  # short version
    ```

 /**
 * Real-time audio player with configurable latency
 *
 * As input, the player regularly receives AVFrames of decoded audio samples.
 * As output, an SDL callback regularly requests audio samples to be played.
 * In the middle, an audio buffer stores the samples produced but not consumed
 * yet.
 *
 * The goal of the player is to feed the audio output with a latency as low as
 * possible while avoiding buffer underrun (i.e. not being able to provide
 * samples when requested).
 *
 * The player aims to feed the audio output with as little latency as possible
 * while avoiding buffer underrun. To achieve this, it attempts to maintain the
 * average buffering (the number of samples present in the buffer) around a
 * target value. If this target buffering is too low, then buffer underrun will
 * occur frequently. If it is too high, then latency will become unacceptable.
 * This target value is configured using the scrcpy option --audio-buffer.
 *
 * The player cannot adjust the sample input rate (it receives samples produced
 * in real-time) or the sample output rate (it must provide samples as
 * requested by the audio output callback). Therefore, it may only apply
 * compensation by resampling (converting _m_ input samples to _n_ output
 * samples).
 *
 * The compensation itself is applied by libswresample (FFmpeg). It is
 * configured using swr_set_compensation(). An important work for the player
 * is to estimate the compensation value regularly and apply it.
 *
 * The estimated buffering level is the result of averaging the "natural"
 * buffering (samples are produced and consumed by blocks, so it must be
 * smoothed), and making instant adjustments resulting of its own actions
 * (explicit compensation and silence insertion on underflow), which are not
 * smoothed.
 *
 * Buffer underflow events can occur when packets arrive too late. In that case,
 * the player inserts silence. Once the packets finally arrive (late), one
 * strategy could be to drop the samples that were replaced by silence, in
 * order to keep a minimal latency. However, dropping samples in case of buffer
 * underflow is inadvisable, as it would temporarily increase the underflow
 * even more and cause very noticeable audio glitches.
 *
 * Therefore, the player doesn't drop any sample on underflow. The compensation
 * mechanism will absorb the delay introduced by the inserted silence.

 /**
 * Real-time audio regulator with configurable latency
 *
 * As input, the regulator regularly receives AVFrames of decoded audio samples.
 * As output, the audio player regularly requests audio samples to be played.
 * In the middle, an audio buffer stores the samples produced but not consumed
 * yet.
 *
 * The goal of the regulator is to feed the audio player with a latency as low
 * as possible while avoiding buffer underrun (i.e. not being able to provide
 * samples when requested).
 *
 * To achieve this, it attempts to maintain the average buffering (the number
 * of samples present in the buffer) around a target value. If this target
 * buffering is too low, then buffer underrun will occur frequently. If it is
 * too high, then latency will become unacceptable. This target value is
 * configured using the scrcpy option --audio-buffer.
 *
 * The regulator cannot adjust the sample input rate (it receives samples
 * produced in real-time) or the sample output rate (it must provide samples as
 * requested by the audio player). Therefore, it may only apply compensation by
 * resampling (converting _m_ input samples to _n_ output samples).
 *
 * The compensation itself is applied by libswresample (FFmpeg). It is
 * configured using swr_set_compensation(). An important work for the regulator
 * is to estimate the compensation value regularly and apply it.
 *
 * The estimated buffering level is the result of averaging the "natural"
 * buffering (samples are produced and consumed by blocks, so it must be
 * smoothed), and making instant adjustments resulting of its own actions
 * (explicit compensation and silence insertion on underflow), which are not
 * smoothed.
 *
 * Buffer underflow events can occur when packets arrive too late. In that case,
 * the regulator inserts silence. Once the packets finally arrive (late), one
 * strategy could be to drop the samples that were replaced by silence, in
 * order to keep a minimal latency. However, dropping samples in case of buffer
 * underflow is inadvisable, as it would temporarily increase the underflow
 * even more and cause very noticeable audio glitches.
 *
 * Therefore, the regulator doesn't drop any sample on underflow. The
 * compensation mechanism will absorb the delay introduced by the inserted
 * silence.

Romain Vimont	342fd1486c	Increase buffering level smoothness The buffering level does not change continuously: it increases abruptly when a packet is received, and decreases abruptly when an audio block is consumed. To estimate the buffering level, a rolling average is used. To make the buffering more stable, increase the smoothness of this rolling average. This decreases the risk of enabling audio compensation due to an estimation error.	2024-02-01 15:14:38 +01:00
Romain Vimont	889ef84461	Improve audio compensation thresholds Use different threshold for enabling and disabling compensation. Concretely, enable compensation if the difference between the average and the target buffering levels exceeds 4 ms (instead of 1 ms). This avoids unnecessary compensation due to small noise in buffering level estimation. But keep a smaller threshold (1 ms) for disabling compensation, so that the buffering level is restored closer to the target value. This avoids to keep the actual level close to the compensation threshold.	2024-02-01 15:14:38 +01:00
Romain Vimont	044b642917	Replace locks by atomics in audio player The audio output thread only reads samples from the buffer, and most of the time, the audio receiver thread only writes samples to the buffer. In these cases, using atomics avoids lock contention. There are still corner cases where the audio receiver thread needs to "read" samples (and drop them), so lock only in these cases.	2024-02-01 15:14:38 +01:00
