/**@class android.media.MediaSync
@extends java.lang.Object

 MediaSync class can be used to synchronously play audio and video streams.
 It can be used to play audio-only or video-only stream, too.

 <p>MediaSync is generally used like this:
 <pre>
 MediaSync sync = new MediaSync();
 sync.setSurface(surface);
 Surface inputSurface = sync.createInputSurface();
 ...
 // MediaCodec videoDecoder = ...;
 videoDecoder.configure(format, inputSurface, ...);
 ...
 sync.setAudioTrack(audioTrack);
 sync.setCallback(new MediaSync.Callback() {
     {@literal @Override}
     public void onAudioBufferConsumed(MediaSync sync, ByteBuffer audioBuffer, int bufferId) {
         ...
     }
 }, null);
 // This needs to be done since sync is paused on creation.
 sync.setPlaybackParams(new PlaybackParams().setSpeed(1.f));

 for (;;) {
   ...
   // send video frames to surface for rendering, e.g., call
   // videoDecoder.releaseOutputBuffer(videoOutputBufferIx, videoPresentationTimeNs);
   // More details are available as below.
   ...
   sync.queueAudio(audioByteBuffer, bufferId, audioPresentationTimeUs); // non-blocking.
   // The audioByteBuffer and bufferId will be returned via callback.
   // More details are available as below.
   ...
     ...
 }
 sync.setPlaybackParams(new PlaybackParams().setSpeed(0.f));
 sync.release();
 sync = null;

 // The following code snippet illustrates how video/audio raw frames are created by
 // MediaCodec's, how they are fed to MediaSync and how they are returned by MediaSync.
 // This is the callback from MediaCodec.
 onOutputBufferAvailable(MediaCodec codec, int bufferId, BufferInfo info) {
     // ...
     if (codec == videoDecoder) {
         // surface timestamp must contain media presentation time in nanoseconds.
         codec.releaseOutputBuffer(bufferId, 1000 * info.presentationTime);
     } else {
         ByteBuffer audioByteBuffer = codec.getOutputBuffer(bufferId);
         sync.queueAudio(audioByteBuffer, bufferId, info.presentationTime);
     }
     // ...
 }

 // This is the callback from MediaSync.
 onAudioBufferConsumed(MediaSync sync, ByteBuffer buffer, int bufferId) {
     // ...
     audioDecoder.releaseBuffer(bufferId, false);
     // ...
 }

 </pre>

 The client needs to configure corresponding sink by setting the Surface and/or AudioTrack
 based on the stream type it will play.
 <p>
 For video, the client needs to call {@link #createInputSurface} to obtain a surface on
 which it will render video frames.
 <p>
 For audio, the client needs to set up audio track correctly, e.g., using {@link android.media.AudioTrack#MODE_STREAM}. The audio buffers are sent to MediaSync directly via {@link #queueAudio}, and are returned to the client via {@link android.media.MediaCodec.Callback#onAudioBufferConsumed}
 asynchronously. The client should not modify an audio buffer till it's returned.
 <p>
 The client can optionally pre-fill audio/video buffers by setting playback rate to 0.0,
 and then feed audio/video buffers to corresponding components. This can reduce possible
 initial underrun.

 The MediaTimestamp represents how the media time correlates to the system time in

 time moves fairly constantly (though the anchor frame may be rebased to a current
 system time, the linear correlation stays steady). Therefore, this method does not
 need to be called often.

 to the current {@link System#nanoTime system time}, so
