This stuff can be repack in a AVI (xivd..) file with some open source tools. Here, a little script to do the hard stuff ;)

You can find the script here : http://svn.pythonfr.org/public/pythonfr/utils/video/mkv2avi.py

# Little script to depack Matroska file, and repack them

ffmpeg -i my_music.mp3 -i in_video.avi -vcodec copy  ouput.avi

You can ever rework on the video after w/ Kino to produce a fade out.

Enjoy video editing on Linux :)

To extract a mp3 from a DVD, the easy way is to use transcode

transcode -i /dev/dvd -x dvd -T 1,2,1 -a 0 -y raw -m track22.mp3

But sometimes, this doesn’t works.. in fact I get a random transcode segfault. As mplayer is the perfect video kniffe. I decided to test this w/ mplayer

mplayer -ao pcm dvd://1 -chapter 22

This won’t build a .mp3 but a big wave file, not matter lame is my friend anyways.

PS: The latest transcode should fix the issue, but I’m unable to build it on my debian. libavcodec2-dev is broken. (Wondering why i’m still using this distro … :(

– thanks #mplayer for the help (as usual)

mencoder tv:// -tv driver=v4l:width=160:height=120  -ovc divx4 -o test.avi

Take care, that you should respect the width/height of the current webcam settings.
