mp4_parser_parse_stts_atom_frame_duration_only: min frame duration is error while reading media header

update: mp4_parser_parse_stts_atom_frame_duration_only: min frame duration is zero while reading media header

This error means that all frames have duration = 0, the file is probably either corrupt or fragmented MP4 (which is not supported)

@erankor thanks for your reply.

the mp4 file is created with programe. it can be lived in vlc. can you tell me which property should be set in atom tree to avoid this problem?

erankor commented 3 years ago

can you send a URL to the MP4? also, you can check if it's fragmented using MP4Box:

# MP4Box -info /tmp/regular.mp4 | grep 'Fragmented File'
        Fragmented File no - 3 track(s)

# MP4Box -info /tmp/fragmented.mp4 | grep 'Fragmented File'
        Fragmented File yes - 2 track(s)
