Converting videos

Tuna-viDS plays videos with the following format:

You can use FFmpeg to convert videos with this command (all one line):

ffmpeg -i <infile> -f avi -r 10 -s 256x192 -b 192k -bt 64k -vcodec libxvid -deinterlace -acodec libmp3lame -ar 32000 -ab 96k -ac 2 tuna-vids.avi

This encodes the video as Xvid at 256×192px, 10fps, 192±64kbps. You can try up to 12fps, but anything higher will slow down the decoder too much. It encodes the audio as stereo MP3 at 32kHz, 96kbps. It muxes it into an AVI container with the filename "tuna-vids.avi". Feel free to experiment with bit rates, sample rates, and frame rates. Just keep the video exactly 256px wide and no more than 192px tall.
