Fragmented MP4

ffmpeg -i "rtsp://..." -movflags +frag_keyframe+separate_moof+default_base_moof+empty_moov -frag_duration 1 -c copy -t 5 sample.mp4

• movflags frag_keyframe Start a new fragment at each video keyframe.
• frag_duration duration Create fragments that are duration microseconds long.
• movflags separate_moof Write a separate moof (movie fragment) atom for each track.
• movflags default_base_moof Similarly to the omit_tfhd_offset, this flag avoids writing the absolute base_data_offset field in tfhd atoms, but does so by using the new default-base-is-moof flag instead.
