join adpcm audio to .mp4 file?

[littlemouse_code]

video using mpeg4 encoding standard ,audio is adpcm , I want to unite them to one mp4 file, someone could tell me if it is feasible

.mp4 doesnt officially support adpcm audio but it could be stored as a private stream.
there are no mp4 muxers that will do that though.

You're best off using mkv for that, mkvmerge makes it very simple to combine both.

Well, ffmpeg muxes everything as private streame, but you can't playback it later.
QT support adpcm, but it's different from M$ ADPCM.... but maybe you can mux it with the M$ code in QT, I would try it.
