Where I have a mkv file, I need to read video frames from mkv file, I need to stream it to remote chrome browser to play it (its a webrtc call). I am successful in parsing the mkv file (like clusters, simple blocks etc). But I have lots of question in respect to how to relates to VP8 encoded frames. I am able to extract payload from simpleblocks and sending those to chrome over RTP (after webrtc call established) as per timestamp we read from mkv file. Chrome is not playing it. So my question is VP8 encoded frames and a simpleblock data in a mkv file, how these two are related. Am I correct to assume one simpleblock data corresponds to one frame in VP8. If any of you has done a streaming onto a browser, can you guide me, give a mkv file, how can we get video frame by frame.
