[REQUIRED] Use case description

https://github.com/google/ExoPlayer/issues/5796#issuecomment-517748828 ExoPlayer currently do audio and video render one after the other. Running renderers of different threads during playback, to improve rendering performance.

We have enabled experimental asynchronous MediaCodec queueing when playing an 8K(HEVC + AAC) content. It's still found the video frames dropping. We invested that MediaCodec decode video and audio quickly in asynchronous mode, but the decoded audio frame consumed slowly during playback(because of the ExoPlayerInternalThread not switched with sufficient frequency), it causes the video frame drops for A/V sync.

Proposed solution

Running renderers in parallel during playback , rather than one after the other.

Alternatives considered

N/A
