MacOS BigSur failed on compling ffmpeg of vf_yadif_videotoolbox.metal problem

[tommyknchan]

I'm using an Intel Macbook Pro (Retina 13-inch, Late 2013 edition) to homebrewing ffmpeg use custom configs as follow:

brew install homebrew-ffmpeg/ffmpeg/ffmpeg --with-libcaca --with-openjpeg --with-fdk-aac --HEAD

Under working environment of MacOS Big Sur 11.6.1 and Xcode command line tool version 13.2. Yet, it happened failure of ffmpeg installation with the log follows:

==> make install
Last 15 lines from /Users/tommy/Library/Logs/Homebrew/ffmpeg/02.make:

Failed to execute metal libavfilter/metal/vf_yadif_videotoolbox.metal -o libavfilter/metal/vf_yadif_videotoolbox.metal.air

Xcode and/or the CLT appear to be misconfigured. Try one or both of the following:
  xcodebuild -license
  sudo xcode-select --switch /path/to/Xcode.app

make: *** [libavfilter/metal/vf_yadif_videotoolbox.metal.air] Error 1
make: *** Waiting for unfinished jobs....

Just asked the GitHub contributors with the same question, but they all said there is a problem of compling "vf_yadif_videotoolbox.metal" file on Intel Mac (ARM Mac seems no such problem per contributor's quote). Is it a problem of compilation during the process? Hope there will be some answers, thank you.
