Philip Langdale 671bdd4b09 avcodec/nvenc: Add support for H.264 High 444 Predictive encoding 
Newer versions of the nvenc hardware support The High 444 Predictive profile
of H.264, and can also do lossless encoding under this profile if desired.

This change introduces support for the profile, and exposes the appropriate
presets for requesting lossless encoding.

I tested lossless by generating a baseline sample with testsrc converted
to raw yuv444p, then encoded the sample with nvenc, then did a framemd5
comparision of both the raw video and the nvenc encode. The framemd5
reports were identical.

  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • ffserver is a multimedia streaming server for live broadcasts.
