Andreas Rheinhardt d91b5020ec avcodec/mpeg12enc: Also inline chroma subsampling 
ff_mpeg1_encode_mb() contains two inlined calls to
mpeg1_encode_mb_internal(); these calls are supposed
to inline the properties depending upon the color space
used. Yet inlining vertical chroma subsampling (which
allows to remove complete branches and blocks depending
upon them) has been forgotten.

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.
