Cannot run program ffmpeg-mac

When I am playing some beatmaps, failed to load beatmap video errors occurred. .opsu.log shows the details.

I checked that opsu/Natives/ffmpeg-mac cannot be run on shell due to the same error.

$ ./opsu/Natives/ffmpeg-mac
zsh: bad CPU type in executable: ./opsu/Natives/ffmpeg-mac

I am using macOS Catalina 10.15.5. I guessed that it does not work because the bundled ffmpeg-mac is not compatible with macOS Catalina.

Thanks.

My workaround is:

1. Install ffmpeg using brew.
2. Run a shell and cd to opsu/Natives/ directory.
3. Remove ffmpeg-mac file. (Or just replace its filename for backup.)
4. Make a symbolic link: ln -s $(where ffmpeg) ./ffmpeg-mac.
5. Restart the opsu.

This works for me.
