A Xvid video player for the Nintendo DS. Tuna-viDS plays AVI files that contain Xvid encoded video and MP3 encoded audio.
Installation
- Download and extract file.
- DLDI patch .nds file and copy it to the root directory of the card.
- Run tuna-open.nds and select an AVI file to play.
User guide
Tuna-viDS plays videos with the following format:
- Video - Up to 256px wide, 192px tall and 12fps. Xvid encoded, non-interlaced.
- Audio - Stereo or mono MP3.
- Container - AVI with chunk index, video must be the first stream (fourcc 00dc).
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, and makes 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.
