Niklas Haas ca77fc2177 avfilter: fix YUV colorspace negotiation for YUVJ 
Ironically, despite being introduced to make YUVJ unnecessary, the new
YUV negotiation logic failed to actually negotiate YUVJ formats
themselves correctly, leading to errors when passing YUVJ frames into
a filter graph. (They were effectively treated like RGB or Grayscale
formats, rather than as forced-full-range YUV, and hence did not have
their colorspace matrix correctly negotiated)

Fix this by splitting off the YUVJ check from ff_fmt_is_regular_yuv().
Obviously, we can trivially undo this change again once YUVJ is actually
deleted from the codebase.

Fixes: #11179

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.
