R3D is not only a codec, it's also a container :)
The container is simple. Starting with a demuxer from blender, I reverse
engineered some missing parts, the result is here:
Audio is PCM, Video is a special JPEG-2000 variant: It has 4 planes,
2 for green, 1 for red and blue each. The color values are arranged
in a Bayer pattern. I use openjpeg for decoding this, it's damn slow
though (slower than realtime).
