[gst-devel] muxing into mp4 files

[Florian Iragne]

Hi,

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

Florian
