There's a closed pull request on the void-packages repository

New package: obs-v4l2sink-3.5
https://github.com/void-linux/void-packages/pull/26031

Description:
I found this plugin for OBS _extremly_ useful. I thought "might as well add this to void's packages". I am sure there's a better way to implement this but this is what I could have done for my first xbps package. If anyone can improve it, that would be awesome!
