Manuel Stoeckl ca594df622 swscale/yuv2rgb: fix conversion to X2RGB10 
This resolves a problem where conversions from YUV to X2RGB10LE
would produce color values a factor 4 too small, because an 8-bit
value was placed in a 10-bit channel.

  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides a mean to alter decoded Audio and Video through chain of filters.
  • 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.
