Ronald S. Bultje 32baeafeee jrev/xvid: hardcode use of C put/add_pixels_clamped.
This removes the last use of the ff_put/add_pixels_clamped global
function pointers, and as such they are removed.

This patch has a negative effect on performance on MIPS, since there's
a SIMD-optimized put/add_pixels_clamped, but no xvid or jrev. From a
code maintenance point of view, that is probably acceptable.

Because the global function pointers are removed, this fixes the following
tsan warnings when running e.g. fate-dnxhr-parse:

  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • 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.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
