--- Comment #14 from Nicolas Dufresne (ndufresne) <nicolas at ndufresne.ca> ---
A verified colorimetry, is a set of colorimetry parameter that as been TRY_FMT.
As only a small subset are tested for performance reason, the default ones,
then it means a very small subset can be used. This is problematic, it a
limitation of the Linux kernel. Now I'm just trying to workaround this,
proposing to add a set of default, but then also accept all the other. Maybe
it's not worth it, and we should just assume they are all supported for encoder
and encoder, and leave it like that until someone fix the Linux kernel
interface.
