@wolenetz notes in the PR:
[[
Problems with determining coded frame duration of SimpleBlock frames in WebM have not been alleviated by WebM muxer guidelines (e.g. to use BlockGroups with BlockDurations for the last block in each track in each cluster, to avoid having to guess the duration). Furthermore, low-latency buffering+decoding of webm motivates an additional note to use BlockGroups with explicit BlockDurations instead of SimpleGroups for all blocks in a cluster (so as to not have to wait until the next block for each track to compute the timestamp delta and use it as the duration).
This change adds a couple non-normative notes to the current editors draft of the MSE WebM byte stream format spec.
@jyavenard, @johnsim, @mwatson2, @jernoble, @chcunningham - I would appreciate your review of this pull request.
