Encoding to 3gp file for mobile phones

If h/s support AAC.

#ffmpeg -i infile.mpeg -vcodec mpeg4 -r 15 -b 128k -s qcif -acodec aac -ar 8000
-ac 1 -ab 13 -f 3gp -y output.3gp

If not

ffmpeg -i infile.mpeg -vcodec mpeg4 -r 15 -b 128k -s qcif -acodec amr_nb -ar 8000
-ac 1 -ab 13 -f 3gp -y output.3gp

For video editing on Linux, LiVES would be very nice.
