[MPlayer-users] Extract h.264 stream to switch container

[Armelius Cameron]

Hello,
I have .mov files with h264 video. I want to move this to MP4 or MKV container 
but I don't want to re-encode the video. I am trying to use mplayer / mencoder 
to extract the stream so that I can use MP4Box from gpac or mkvtools to add 
the stream to the container, but I am having trouble figuring out how. 
Is this possible at all ? How to do it ?

Thank you very much in advance for any help.

This is what ffmpeg -i give me of the video:

ffmpeg -i movie1.mov 
ffmpeg version 0.8.9, Copyright (c) 2000-2011 the FFmpeg developers

Seems stream 0 codec frame rate differs from container frame rate: 61440.00 
(61440/1) -> 30.00 (30/1)
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'movie1.mov':
