ffmpeg + VMAF issues

ab-av1 relies on having a recent ffmpeg compiled with libvmaf & having the VMAF models accessible. This can be tested with

ffmpeg -i vid.mp4 -i vid2.mp4 -lavfi libvmaf -f null -

If this doesn't work try

Manually downloading VMAF models to /usr/local/share/model/ (at least models vmaf_v0.6.1.json & vmaf_4k_v0.6.1.json).
