The reason why I feel funny is that ffmpeg commit of "06a54a4ec73ea6eb8cec41b7af75367bafb075e0(Date: Sat Jan 22 10:32:34 2022 +0100)" can configure and make correctly, but current git head can't configure.  I suppose something wrong was happened after 2022/01/22.

So, what's your actual version of libvmaf? Because _after_ commit
06a54a4ec73ea6eb8cec41b7af75367bafb075e0, the requirement was increased
to 2.0.0.

If you're using git anyway, you could do a "git bisect".

It seems to me that vmaf_init() had existed before, so I'm not sure why
this would happen.
