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 *)’ ==12116== Thread 6:

FFmpeg README
FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.
Libraries
libavcodecprovides implementation of a wider range of codecs.libavformatimplements streaming protocols, container formats and basic I/O access.libavutilincludes hashers, decompressors and miscellaneous utility functions.libavfilterprovides a mean to alter decoded Audio and Video through chain of filters.libavdeviceprovides an abstraction to access capture and playback devices.libswresampleimplements audio mixing and resampling routines.libswscaleimplements 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,ismindexandqt-faststart.
