[MPlayer-users] Extract h.264 stream to switch container
Armelius Cameron
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
<snip>
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':

Above line works fine with current FFmpeg.

This is outdated.

Both on this list and the FFmpeg mailing lists, please do not cut
the console output (except for repeated lines), but always post
complete, uncut console output.
To extract the h264 stream from mkv:
mplayer file.mkv -dumpvideo
ffmpeg -i file.mkv -vcodec copy out.h264
H264 in mp4 has a special syntax (if the file is valid) and
mplayer file.mp4 -dumpvideo produces an invalid file
ffmpeg -i file.mp4 -vcodec copy -vbsf h264_mp4toannexb out.h264

Last time I've checked (today), it worked that way:
> $ MP4Box -add bbc-blue_m1080p.mov bbc.mp4
> IsoMedia import - track ID 1 - Audio (SR 44100 - 2 channels)
> IsoMedia import - track ID 2 - Video (size 1920 x 1072)
> Saving to bbc.mp4: 0.500 secs Interleaving
And you could check whatever GPAC recognizes streams in your file by:
> $ MP4Box -info bbc-blue_m1080p.mov
> * Movie Info *
> Timescale 600 - Duration 00:03:22.165
> Fragmented File no - 2 track(s)
> File suitable for progressive download (moov before mdat)

So extracting just a video stream would be:
> $ MP4Box -add bbc-blue_m1080p.mov#video h264.mp4
> IsoMedia import - track ID 2 - Video (size 1920 x 1072)
> Saving to h264.mp4: 0.500 secs Interleaving
