Rodger Combs 6ebe88f3a4 lavf/isom: add Dolby Vision sample entry codes for HEVC and H.264 
These are registered identifiers at the MPEG-4 RA, which are
defined as to be utilized for Dolby Vision AVC/HEVC streams that
are not correctly presentable by standards-compliant AVC/HEVC players.

According to the Dolby Vision specification for ISOBMFF, these sample
entry codes are specified to have the standard AVC or HEVC decoder
configuration box in addition to the Dolby custom DOVIConfigurationBox.
This is what enables us to decode the streams without custom parsing.

For correct presentation information from the DOVIConfigurationBox
is required (YCbCr or modified ICtCP, SDR or HDR, base or enhancement
layer).

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.
