arch1t3cht 72e5381123 avfilter/vf_subtitles: Respect YCbCr Matrix header 
As specified in libass's ass_types.h, the colors or ASS_Images
should be converted to YCbCr using the matrix/range specified in
the track's YCbCrMatrix field (unless that field is set to YCBCR_NONE,
and defaulting to TV.601 if the header is missing).

This does not affect any subtitles generated or transcoded by ffmpeg,
since these contain a 'YCbCrMatrix: None' header.

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.
