26 Nov 2007 Convert videos to 3gp format

Posted by

This bash script converts videos like AVI-files to the 3gp format used on newer cell phones like Nokia N95. To use it you should have the libamr_nb and libamr_nw flags available to ffmpeg.< /p>

If you don’t see those flags this script won’t work.

This script can be modified to work on the Sony Ericsson k700i by changing -s to 176×144, its resolution.
