[Mp4-tech] Extracting BIFS Data

[Bharat P. SONI]

Hi,
you are right that data exists in a track. BIFS data also have a unique
stream id (similar to other elementary streams) and there is some kind of
mapping between stream id (ES_ID) and the track_id (I am not sure if both
are same). So you find out the track id and extract the data from the track
just like any other elementary stream.
Regards,
Bharat

Hi,
I am attempting to extract BIFS data from an MP4 file. Can someone tell me
where in the file the data exists? From what I understand it lives in the
trak atom but I'm not entirely sure.
Regards,
Ben
