Well, and for the same reason jack doesn't use 24bit PCM as native
format, this is a not a good idea for video data.

Something that wouldn't cripple my data, if my input data has 12bpp. I
don't think you can solve this problem by just using one pixel format.
RGB with floats could be one possible solution, but one 4K frame would
be 99MB.
