Niklas Haas 96d2a40b9e avcodec/pnm: explicitly tag color range 
PGMYUV seems to be always limited range. This was a format originally
invented by FFmpeg at a time when YUVJ distinguished limited from full
range YUV, and this codec never appeared to output YUVJ in any
circumstance, so hard-coding limited range preserves the status quo.

The other formats are explicitly documented to be full range RGB/gray
formats. That said, don't tag them yet, due to outstanding bugs w.r.t
grayscale formats and color range handling.

This change in behavior updates a bunch of FATE tests in trivial ways
(added tagging being the only difference).

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.
