3ds-Theora example

POC example of theora decoding for the Nintendo 3DS family of systems using libctru and citro2d.

Usage

You can create a compatible video file using the following command: ffmpeg -i 'input.ext' -vcodec theora -vf scale=400:-1 -acodec libvorbis -ar 32000 "output.ogv" You can change the quality by using the -q:v flag. The value can be any interger from 0-10 with 10 being the highest quality. The old 3ds has limited processing power so I do not recomment using 10, but any value between 0 and 7 should be fine. (4 is recommended) You can also just set the bitrate manually using the -b:v flag. (Somewhere around 500k is recomended) You can place your generated videos in the /videos directory on your sd card, if it doesn't exist, create it.
