Andreas Rheinhardt d3f35224a9 avcodec/sheervideo: Reduce the size of static arrays 
The SheerVideo decoder uses VLC tables which are currently stored in
large arrays that contain the length of each leaf of the corresponding
tree from left to right, taking 15.5KB of space. But all these arrays
follow a common pattern: First the entries are ascending and then they
are descending with lots of successive entries have the same value.
Therefore it makes sense to use a run-length encoding to store them, as
this commit does. Notice that the length 16 has to be treated specially
because there are arrays with more than 256 consecutive entries with
value 16 and because the length of the entries start to descend from
this length onward.

FFmpeg README

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

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • 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.
