Feature request: Add GPU-based encoding (targeting NVIDIA's NVENC) and GPU-based scaling.

[Brainiarc7]

Hello there,

Looking at how transcoding is being called up:

(a). Adding a GPU-based encoder, specifically NVENC, configurable with presets and the global GPU selection option, and;

(b). Most importantly, a GPU-based filter, such as scale_cuda, scale_npp, and yadif_cuda (targeting NVIDIA-based systems) would greatly eliminate the single largest performance bottleneck. CPU-bound scaling and deinterlacing is expensive, consuming precious CPU cycles that eventually lower transcode density per target host.

A good primer on what's possible with this addition can be found here.

Thank you for your interest and forwarding information about NVENC. I will certainly review it and see if it is something I can get integrated.
