Converting 3gp video format on Linux?
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. C.

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

<snip> Thanks for the lead. This got me looking the right direction, and I found and all called Lin3gp. this is basically a GUI frontend to ffmpg and converts avi to 3gp.. and it works perfectly. And the ffmpg line you provided to convert the 3gp back to avi works perfct as well.. thanks. As an aside, I tested some Windows native apps on a Windows PC, and... they converted the 3gps, but the sound was all out of synch with the video no matter what codec I selected. Converting on Linux - although command line - was perfectly in sych. I love it when Linux comes out ahead.. which it does all the time for me :-) :-) C.
