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.

I found that the fact was happened on:

commit: 3d29724c008d8f27fecf85757152789b074e8ef9
commit title: avfilter/vf_libvmaf: update filter for libvmaf v2.0.0
commit date: Mon, 24 Jan 2022 04:41:30 +0900 (11:41 -0800)

In that, configure of ffmpeg was changed as:

Here,  I can find out "vmaf_init", might be cause of issue...
