[FFmpeg-devel] [Patch] nvenc : Add P016 support

[Yogender Gupta]

>> 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,
Yogender
