Niklas Haas 2a942b4b3a avfilter/vf_format: re-use AVFilterFormats for pix_fmt parsing 
Rewrite the format parsing code to make it more easily generalizable. In
particular, `invert_formats` does not depend on the type of format list
passed to it, which allows me to re-use this helper in an upcoming
commit.

Slightly shortens the code, at the sole cost of doing several malloc
(ff_add_format) instead of a single malloc.

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

The offline documentation is available in the doc/ directory.
