    Add 'superframe' index · 522d4bf8
    John Koleszar authored
    A 'superframe' is a group of frames that share the same PTS, but have a
    defined decoding order. This commit adds the ability to append an index
    to such a group of frames, allowing for random access to the constituent
    frames. This could be useful for frame-level parallelism or partial
    decoding in a multilayer scenario.
    Decoding the stream serially without such an index should work as a
    fallback, and VP9/TestSuperframeIndexIsOptional verifies that.
