[Mp4-tech] BIFS/OD track identification

[Praveen Singh]

Hi experts,
I have a doubt regarding mp4 files.
I was wondering in ISO/IEC 14496-14 its defined that "iods" contains track
IDs of BIFS and OD streams. But nowhere in specification is defined how to
recognize the BIFS/OD tracks from these IDs (without refering the
corrosponding BIFS/OD tracks i.e. odsm & sdsm)? There may be max. 255 track
IDs in iods box !!!
