I know what fragmented MP4 is and I have created it using ffmpeg see http://ffmpeg.org/ffmpeg.html#MOV_002fMP4_002fISMV My question was rather meant like "is there some non-obvious thing that ffmpeg does not support regarding fragmented mp4" ------------------------- Robert, my apologies, I did in fact misunderstand your questions. Looks like I need to get caught up on the latest code. _______________________________________________ Libav-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/libav-user
