An 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
User guide
Tuna-viDS plays videos with the following format:
Video: 256px wide, up to 192px tall, up to 12fps, Xvid encoded, non-interlaced
Audio: Stereo or mono MP3
Container: AVI with chunk index, video must be the first stream (fourcc 00dc)
User 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.
Controls
B - play/pause
X - toggle bottom backlight
Left - increase video delay by one frame
Right - decrease video delay by one frame
Compatibility
Tested on: Flashcart M3DS Real with firmware 3.4
