GPAC, http://gpac.wp.mines-telecom.fr/ , can be used to do video segmentation along with MPEG-DASH spec. One type of results is a combination of init files (ex, init.mp4) and several roughly fixed-duration segments (ex, segment-%d.m4s). What if I just got those results and I like to reverse/combine them back to one full source.mp4 file? Can I use GPAC or ffmpeg for this? You can just use the cat command or similar tools to do this job: cat init.mp4 > source.mp4 cat segment-1.m4s >> source.mp4 cat segment-2.m4s >> source.mp4 ... To do this automatically for all segments in the current folder,

I'm creating a fragmented mp4 for html5 streaming, using the following command: -i rtsp://172.20.28.52:554/h264 -vcodec copy -an -f mp4 -reset_timestamps 1 -movflags empty_moov+default_base_moof+frag_keyframe -loglevel quiet - "-i rtsp://172.20.28.52:554/h264" because the source is h264 in rtp packets stream from an ip camera. For the sake of testing, the camera is set with GOP of 1 (i.e. all frames are key frames) "-vcodec copy" because I don't need transcoding, only remuxing to mp4. "-movflags empty_moov+default_base_moof+frag_keyframe" to create a fragmented mp4 according to the media

I'm trying to live stream H.264 content to HTML5 using the media source extensions API. The following method works pretty well: ffmpeg -i rtsp://10.50.1.29/media/video1 -vcodec copy -f mp4 -reset_timestamps 1 -movflags frag_keyframe+empty_moov -loglevel quiet out.mp4 and then: mp4box -dash 1000 -frag 1000 -frag-rap out.mp4 I can take the MP4Box output ( out_dashinit.mp4 ) and send it through Web Sockets, chunk by chunk, to a JavaScript client that feeds it to the media source API. However, this is not a good method for live content. What I'm trying to do now, is to create a single pipeline in
