Although it already worked with mplayer... Makes you wonder why it's required in the first place, not?

MP4Box -hint test.mp4 acid at cassiopee #5973 Hinting file with Path-MTU 1500 Bytes Hinting track ID 1 - Type "avc1:avc1" (H264) - BW 728 kbps Hinting track ID 2 - Type "mp4a:mp4a" (mpeg4-generic) - BW 63 kbps Saving test.mp4: 0.500 secs Interleaving Is that good ?

Don't know ;-)

I was actually referring to:

MP4Box -raw 1

Can you please check this? What version of gpac are you using? I am using cvs from last week.

Exactly, mostly Apple stuff, FCP, Quicktime player. I based my efforts on samples produced by FCP.

Hmmm. It would be nice if there was some test suite or reference "player". But at least if quicktime can play it, I guess most people will be happy ;-)

I guess you already checked quicktime player, and it didn't play before your patches and it did after your patches?
