Sending periodic metadata in fragmented live MP4 stream?
问题 As suggested by the topic, I'm wondering if it's possible to send metadata about the stream contents periodically in a fragmented MP4 live stream. I'm using the following command (1) to get fragmented MP4: ffmpeg -i rtsp://admin:12345@192.168.0.157 -c:v copy -an -movflags empty_moov+omit_tfhd_offset+frag_keyframe+default_base_moof -f mp4 ... My main program reads the fragments from this command from either stdout or from a (unix domain) socket and gets: ftyp moov moof mdat moof mdat moof mdat
