Comment (by Balling):

 I still do not get this issue. Imagine you have 120 fps stream. The
 inverse of that is how much you have time to spend on convert, and it is
 so much more than conversion from anything to semi-planar NV12 or weird
 packed chroma, planar luma format like P010. Whatever you are doing here
 it is clearly wrong. AVX512 and other can be used to accelerate this
 further.

 GPUs adding more garbage formats is also stupid since it adds even more
 transistors in silicon budget.

 Changing h264 decoder or x264 encoder or whatever to a different pixel
 format is even more insane, since the question is what and how oixels are
 koced internally and it is 100x more complex than whatever you want to
 output.

 Moroever nvenc supports p010 input and it makes sense to use HW encoder
 more less energy and less problems.

 Finally, as I said it is impossible to decode 4k60 VP9 already in
 software, so it does not even matter, because with Hardware overlays
 (color management of which Intel will fix soon, I hope) output to display
 directly, CPU just draws the overlay and menus.
