Just got macOS upgraded to [Ventura](https://www.apple.com/macos/monterey-preview/) and found that FFmpeg is not working and throwing the following error:

```bash
dyld[54425]: Library not loaded: /opt/homebrew/opt/rav1e/lib/librav1e.0.5.dylib
  Referenced from: <D4B0734B-405C-3440-A545-A06D935C834D> /opt/homebrew/Cellar/ffmpeg/5.1.2/bin/ffmpeg

fish: Job 1, 'ffmpeg' terminated by signal SIGABRT (Abort)
```

It's obviously a dependency problem. 

According to [this issue](https://github.com/Homebrew/discussions/discussions/2705), reinstalling `rav1e` shall fix it:

```bash
brew reinstall rav1e
```
