i using combination of fragmented mp4 , websockets stream live video stream web browser mse takes over. i have fragmented appropriate fmp4 format using ffmpeg , have checked data using mpeg4parser tool. utilising websocket server, incoming data broadcasted browser clients connected via websocket. works fine both playback , live streaming(using rtsp stream input). the problem facing occurs when client tries access stream midway, i.e, once ffmpeg stream has started. have saved init segment(ftyp + moov) elements in queue buffer in websocket server. queue buffer sends data each new client on connection. i believe data sent correctly since browser console not throw 'media source element not found' error. yet no video streamed when receives broadcasted moof/mdat pairs. so couple of questions answer are: 1) have observer each moof element contains sequence number in it's mfhd child element. have start 1 always, naturally not case video stream accessed midway? 2) p...
