uhm ok
I've done:
ffmpeg -i demo.avi -an -vcodec h263 -r 10 -s qcif -b 40k -g 50 -t 60
video.mp4

> mp4creator -hint=1 yourfile.mp4

but when I start mp4creator, I have this error:

MP4ERROR: MP4File::FindIntegerProperty: no such property -
moov.trak[0].mdia.minf.stbl.stsd.*.esds.decConfigDescr.objectTypeId
MP4ERROR: MP4File::FindIntegerProperty: no such property -
moov.trak[1].mdia.minf.stbl.stsd.*.esds.decConfigDescr.objectTypeId

And of course the video is not played back with mp4play in * :

uhm
I'm missing something ?
