[gst-devel] muxing into mp4 files

i'm currently using ffmux_ipod to mux a h264 stream into an
'ipod/iphone' compliant mp4 file.
It works. However, from the begining, i've noticed some video quality
problems (the video seems to "freeze" on one frame every 5 seconds.
Since it match the keyframe interval i've defined on the coder, i
thought it was an artifact due to the coder.
Today, i've tried to mp4mux/qtmux to achieve the same goal (mp4 file
ipod/iphone compliant). I'm not able to play these files on iOS device,
however the strange video quality problem has disappeared.
So few questions :
* is there a way to force mp4mux to mux into an ios compliant mp4
file? I've tried lots of parameters tunning without success
* since the quality problem is the same using ffmux_mp4 and
ffmux_ipod, i think it is related somewhat to ffmpeg. Does anybody have
a idea about the problem? I haven't found anything in the bug tracker.
thanks for any help
