Martin Storsjö ec2ceefcfa fate.sh: Allow specifying --ar through a separate variable 
This avoids needing to use the extra_conf variable. That variable
is problematic for setting a value that contains spaces.

This adds options for another tool in the same fashion as other
tools were added in 523d688c2b.

  • 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

  • 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.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
