The issue I found while doing android cts. Some test videos contains reserved obu type, and the MSDK returned UMC::UMC_ERR_NOT_IMPLEMENTED. According to the av1-spec, we should ignore it and continue to process. |

@zhangyichix I cannot find section 6.2.6 from your spec URL. Do you mean section 6.3? |

@wangyan-intel sorry, it is 6.2.2. OBU header semantics. |

There was a problem hiding this comment.
Please use Enum element instead of hard code number.

Some av1 videos may contain reserved units. We should ignore it instead of returning an error.
