public class Libgav1VideoRenderer extends SimpleDecoderVideoRenderer
This renderer accepts the following messages sent via ExoPlayer#createMessage(Target)
on the playback thread:
C.MSG_SET_SURFACE to set the output surface. The message payload
should be the target Surface, or null.
C.MSG_SET_VIDEO_DECODER_OUTPUT_BUFFER_RENDERER to set the output
buffer renderer. The message payload should be the target VideoDecoderOutputBufferRenderer, or null.
