I'm trying to use Nvidia's h264_nvenc video encoder with ffmpeg but I can't find a single source of documentation for it. I want to know what options are supported and what they do.
The software libx264 encoder has good documentation: http://trac.ffmpeg.org/wiki/Encode/H.264
But I can't find the equivalent for h264_nvenc.
There is a little bit of information on https://trac.ffmpeg.org/wiki/HWAccelIntro and https://developer.nvidia.com/blog/nvidia-ffmpeg-transcoding-guide/ but these seem to just contain examples, whereas I'm looking for more of a reference for what the encoder can do. Thanks
