Duration field of Video Data in Media Source Reader::On Video Decoded is incorrect with Web M
If a SourceBufferDecoder reaches the end of its data then the associated WebMReader uses GetMediaEndTime to compute the sample duration, taking that time as the time of the next sample. SourceBufferDecoder::GetMediaEndTime returns the duration of the resource which results in the computed sample time being incorrect. Is it safe to change GetMediaEndTime to return the time of the last item in the buffered data for the SourceBufferDecoder? Or do we change WebMReader's behaviour here.
Not sure how I managed that, but I posted bug 1061402's comment here and this bug's comment there. Made it private to avoid confusion. Intended comment: As far as I can tell, GetEndMediaTime is only used by the WebMReader. I think it's confusing given the existence of GetMediaDuration. My preference is to remove it entirely, and compute the last frame duration in WebMReader using the Δt between the current and previous frame as the frame duration.
