Jan Ekström dbe40478e2 avcodec/libx265: improve full range flag setting logic 
Unlike libx264, libx265 does not have a separate "unspecified"/"auto"
default for color range, so we do always have to specify it.
Thus, we are required to handle the RGB case on the libavcodec
side to enable the correct value to be written out in in case
of RGB content with unspecified color range being received.

In other words:
1. If the user has set color range specifically, follow that.
2. If the user has not set color range specifically, set full
   range by default in case of RGB and YUVJ pixel formats.

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 a mean to alter decoded Audio and Video through chain of 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.

The online documentation is available in the main website and in the wiki.
