Currently, a frame is dropped if it's requested release time is in the past.
This mode was added to support previewing. However, in normal ExoPlayer
playback, slightly late frames (<30ms late) are also rendered. On MediaCodec
side, this means calling `releaseOutputBuffer` with a release time in the
past.
