James Almer 52b44e9d15 Merge commit 'c31f6b1d61759436ef50c094e7f4c8005e97614a' 
* commit 'c31f6b1d61759436ef50c094e7f4c8005e97614a':
  avprobe: Print a user-friendly version of the display matrix
  avprobe: Support printing strings with empty keys

This commit is a noop. ffprobe is considerably different than avprobe
and is already printing display matrix values in a user readable way.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

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