STR: 1- Open https://registry.khronos.org/webgl/sdk/tests/resources/red-green.webmvp8.webm Actual: A media error is produced. Expected: Video plays. The video contains an empty vorbis track, this causes the AVFObjC player to later fail as if it finds a track that is not playbable to be a fatal error (failure in MediaPlayerPrivateAVFoundationObjC::trackIsPlayable)

In this particular case, we could make the track be ignored by the MediaFormatReader if a track is disabled because it contains no data. However, this begs the question: should a file fail to play when a given track is invalid or should it be just ignored?
