Kacper Michajłow 1c45104f74 avcodec/h2645_sei: validate Mastering Display Colour Volume SEI values 
As we can read in ST 2086:

Values outside the specified ranges of luminance and chromaticity values
are not reserved by SMPTE, and can be used for purposes outside the
scope of this standard.

This is further acknowledged by ITU-T H.264 and ITU-T H.265. Which says
that values out of range are unknown or unspecified or specified by
other means not specified in this Specification.

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.
