Has anyone tried re-encoging/converting the 3gp video format that is common on most mobile phones?
I'd like to be able to convert the 3gp video I have copied off the phone to an mpg format - purely for convenience.
It would also be nice if I could convert regular video formats (ie avi ang mpg) for 3gp...
I've poked around in the man pages for mencoder and also Googled a bit... loads of Windows utils but no useable hits on Linux.

I use ffmpeg for this. The following converts from the phone to an avi. ffmpeg -i input.3gp -f avi -vcodec xvid -acodec mp3 output.avi I use this to create videos for the phone. ffmpeg -i input.whatever -f avi -vcodec xvid -b 112 -r 12 -s cif -acodec mp3 -ab 24 -ar 16000 output.avi I've loaded SmartMovie (from Lonely Cat Games) onto my phone so it can play XVid encoded AVIs. The above command wont produce a video that you would want to watch on anything larger than your phone. On the other hand, a movie from DVD ended up at about 111MB. With a 512MB card I can have two full length movies and still have room left over for a bit of music. The movie was backed up from DVD as follows: mencoder dvd://12 -ovc lavc -alang en -oac mp3lame -lameopts br=128:vol=9 -o output.avi The number 12 in the above command would be different for other DVDs. Try the following with different numbers until you get what you want. mplayer dvd://12 -- Louis Richards
