Andreas Rheinhardt 2e92e1fb27 fate/matroska: Add test for chapters, Vorbis and WebM DASH 
Moreover, putting the Cues in front of the Clusters by reserving space

The new capability of using ffprobe during a remux/transcode test are
used here for information about the chapters.

  • 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.
