Nicolas George a8ab52fae7 lavfi/vf_libvmaf: convert to framesync2.
After this commit, the code compiles, but on my setup it
segfaults before and after. It also prints the very worrying
warning:

src/libavfilter/vf_libvmaf.c:161:66: warning: passing argument 4 of ‘compute_vmaf’ from incompatible pointer type [-Wincompatible-pointer-types]
/tmp/i/include/libvmaf.h:26:8: note: expected ‘int (*)(float *, float *, float *, int,  void *)’ but argument is of type ‘int (*)(float *, float *, float *, int,  double *, void *)’

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.
  • ffserver is a multimedia streaming server for live broadcasts.
  • 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.

Examples
