Andreas Rheinhardt 27562bf022 avcodec/x86/mpegvideoenc_template: Disable dead code 
Since bfb28b5ce8 the permutation
type FF_IDCT_PERM_SIMPLE is ARCH_X86_32-only. So use this

  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected 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
