[MEncoder-users] Remuxing to mp4 on windows

[Nicolas Hesler]

I've had trouble remuxing to mp4 on windows following the docs: 
14.7.8. Remuxing as MP4

Mencoder command line example:

mencoder -vf harddup -ovc x264 -x264encopts 
pass=1:turbo:bitrate=900:bframes=1:me=umh:partitions=all:trellis=1:qp_step=4:qcomp=0.7:
direct_pred=auto:keyint=300 -oac faac -faacopts br=192:mpeg=4:object=2 
-channels 2
-srate 48000 -ofps 24000/1001 export.avs -o h264.avi

I then dump the streams using Mplayer.

I've tried using mp4creator - mpeg4ip version 1.5.11 (windows binary), 
but I get the following message:

"Error decoding sei message"  <----Does anyone know what this means???

command line example: mp4creator -create=h264.h264 -rate 23.976 out.mp4

Also, I have had trouble with MP4Box - GPAC version 0.4.5-DEV (build 19 
- Apr 13 2008) and the method described to dump the video and audio 
streams using Mplayer.

Mp4box reports that:

"Cannot find H264 start code
Error importing h264.h264:fps=23.976: BitStream Not Compliant"   
<----Does anyone know what this means???

command line example : MP4Box -add h264.h264:fps=23.976 out.mp4

The only method that has seemed to work for me is to create the avi 
using avi2raw (mpeg4ip version 1.5.11)
to dump the video and then use MP4Box to mux.   mp4creator does not seem 
to work with either avi2raw or mplayer dumps.

Does anyone have anything to add to this?  Another technique? Something 
I'm doing wrong?
