There's a closed pull request on the void-packages repository
Update libaom and enable it for ffmpeg
https://github.com/void-linux/void-packages/pull/23542
Description:
Fixes #23538
I currently get segfaults when trying to use this with ffmpeg.
```
$ ffmpeg -i example.mp4 -c:v libaom-av1 -crf 30 -b:v 0 -strict experimental av1_test.mkv
```
gets me this backtrace:

I'm not sure we can enable it when it's like this. I can try using FFMPEG 4.3 to see if it works better then. I am on musl, so that might be an issue.
I also don't know how to test for gstreamer AV1 support.
