Ramiro Polla a16e674f7f swscale/tests/swscale: add -api parameter (supersedes -legacy parameter) 
The "-legacy 1" option was added in 101a2f6fc6 to run the main
conversion with the legacy scaler. This was done by forcing the use of
the legacy API. This way, it was possible to pass "-flags unstable" and
still ensure the legacy scaler path was being taken.

New legacy-related parameters will be added to the test tool, so it
makes sense to rename the -legacy option to reflect what it was
actually doing.

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.

Documentation
