I figured as much. I'm happy to look into it.

What if I just wanted to implement encoding first for testing
purposes? There are already codec IDs for v210 and r210. Maybe the
first step should be to get the encoders working with RGB48, then look
into optimizing it for packed 32 bit. Maybe Reimar can comment, as he
wrote the r210 decoder.
