Vittorio Giovara ce7ca726b2 vf_tonemap: Fix logic for detecting the maximum peak of untagged sources 
When there is no metadata attached to a frame, take into account both
the PQ and HLG transfers, and change the HLG default value to 10:
the value of 12 is the maximum range in scene referred light, but
the reference OOTF maps this from 0 to 1000 cd/m² on the ideal HLG
monitor.

This matches what vf_tonemap_opencl does.

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
