Niklas Haas 59c39a79ca tests/swscale: rewrite on top of new API 
This rewrite cleans up the code to use AVFrames and the new swscale API. The
log format has also been simplified and expanded to account for the new
options. (Not yet implemented)

The self testing code path has also been expanded to test the new swscale
implementation against the old one, to serve as an unchanging reference. This
does not accomplish much yet, but serves as a framework for future work.

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 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.
