wolenetz has just created a new issue for https://github.com/w3c/media-source: == WebM bytestream format is too restrictive around "random access points" == The current text: "A SimpleBlock element with its Keyframe flag set signals the location of a random access point for that track. Media segments containing multiple tracks are only considered a random access point if the first SimpleBlock for each track has its Keyframe flag set. The order of the multiplexed blocks must conform to the WebM Muxer Guidelines." This has multiple overly-restrictive pieces that could be relaxed, given the robustness of the coded frame processing algorithm. I suggest: 1) Replacing the first sentence with something like "A random access point for a track is signalled by a SimpleBlock element with its Keyframe flag set for that track, or a BlockGroup element having no ReferenceBlock elements for that track." 2) Drop the second sentence; use (1) and the coded frame processing algorithm. Keep the third sentence as-is. Do these changes relax that bytestream spec too much to achieve reliable interoperability?
