what is the stsd syntax for PCM wave?

[chungae9ri]

Hi everyone.
I am developing the mp4 container.
Now I want to mux mpeg4 video data and raw wave audio data(PCM 8KHz, 16bit/sample) into the mp4 container. Is it possible? if possible, what is the stsd atom syntax about the wave audio?

I doubt that this is possible while staying compliant with ISO 14496-1/-12/-14. However, the Quicktime file format defines an stsd which can carry uncompressed PCM.

The fourcc is 'twos' or 'sowt'.

Look for the chapter "Media Data Atom Types"->"Sound Media" at
http://developer.apple.com/documentation/QuickTime/QTFF/

Technically it is no problem to mux PCM audio into MP4 (you can mux possibly any audio format into MP4), the questions is always if you are compliant ;)

afaik mpeg runs a special site which can be used for "standardising non-standardised formats" in .mp4 (and other formats of its family). if you dont find your needed info there, than there is no standardised way for placing wave in mp4
