Both the extension OPUS decoder and the OMX/C2 MediaCodec implementations for OPUS and VORBIS decode into the channel layout defined by VORBIS. See https://www.xiph.org/vorbis/doc/Vorbis_I_spec.html#x1-140001.2.3 While this is technically correct for a stand-alone OPUS or VORBIS decoder, it doesn't match the channel layout expected by Android. See https://developer.android.com/reference/android/media/AudioFormat#channelMask The fix is to apply the channel mapping after decoding if needed. Also add e2e tests with audio dumps for the extension renderer, including a new 5.1 channel test file. Issue: google/ExoPlayer#8396 #minor-release PiperOrigin-RevId: 588004832
