[Mp4-tech] Re: MP4 file format and H.264 CBR streams

[Tchi Southivong]

Hello,
I was wondering if it is possible and correct to store a H.264 CBR
stream in a MP4 file?
Indeed, the MP4 file format doesn't allow filler data nal units.
However, they actually can be present in a CBR stream that fulfills the
HRD requirements (to prevent under/overflows).
I would be tempted to store the CBR stream in the MP4 file by filtering
out the filler nal units. But that isn't really satisfactory since it
would be quite inconvenient to recover the original stream if I need to
export it to another container (like Transport Stream).
I would be really interested to get your comments and advice on this
situation.
Thanks.
Best Regards,
Tchi.
