This is a final - working - version of my script, which I use to convert files supported by ffmpeg to MOV format, supported by my iPod Video G5.
Everything was tested to be easy to use (finally, after installation). If You have any problems with it, just let me know - I'll try to help as far as I can.
Just download "avi2mov" script, and save it in /usr/sbin/ directory (You can save it in any directory, but take care later, because i assume, you've saved it in /usr/sbin/ :) ).
After this, You need to set proper permissions, so use chmod:
chmod +x /usr/sbin/avi2mov
Finally, You need to add this converter to Service Menu. Create file
with Kate for example, and copy and paste this code:
[Desktop Action MediaConvertFile]
Name=Convert selected file to mov ...
And that's all! :)
