• Audio:
  • Add onAudioTrackInitialized and onAudioTrackReleased callbacks to AnalyticsListener, AudioRendererEventListener and AudioSink.Listener.
• Metadata:
  • MetadataDecoder.decode will no longer be called for "decode-only" samples as the implementation must return null anyway.
• Session:
  • Add session demo module for Automotive OS and enable session demo for Android Auto.
• DASH Extension:
  • Allow multiple of the same DASH identifier in segment template url.
• RTSP Extension:
  • Use RTSP Setup Response timeout value in time interval of sending keep-alive RTSP Options requests (#662).
• Decoder Extensions (FFmpeg, VP9, AV1, MIDI, etc.):
  • Add DecoderOutputBuffer.shouldBeSkipped to directly mark output buffers that don't need to be presented. This is preferred over C.BUFFER_FLAG_DECODE_ONLY that will be deprecated.
  • Add Decoder.setOutputStartTimeUs and SimpleDecoder.isAtLeastOutputStartTimeUs to allow decoders to drop decode-only samples before the start time. This should be preferred to Buffer.isDecodeOnly that will be deprecated.
