I can push, but to answer Timo's question: I did not add P016 to
nvenc because it is technically not correct to pass 12bit content
through a 10bit surface - that will lead to truncation, rather than
dithering. If you are telling us that nvenc supports 12bit >> input
and will correctly dither, then great. Otherwise, it's more correct
to not support and force dithering to happen through swscale. You
could also write cuda accelerated dithering.
I have dropped the NVENC patch for now (we will build a P016 to P010
CUDA dithering filter). Attached the other patches, also taking into
account some code formatting comments.
Thanks,

Hi Yogender,
That's great.
Your patches look fine, although they need micro version bumps in
libavfilter and libavutil.
I've added those to my local copy of the patches, but I know realise I
can't push either,
as I'm travelling for another week. I'll push them when I get back.
Thanks,
