## About ffmpeg-obs
# OBS Project actually patch FFmpeg to fix some issues and also add RIST support starting from 27.2.
# So I created ffmpeg-obs, a ffmpeg package that ensure that you have those.
# I really wanted to not do this but some fixes are needed, so I did my best to add those "feature-set options".
# They allow you to build ffmpeg with feature-set based on other ffmpeg packages from AUR.

### Feature-set options
### WARNING: There is no arch check so don't enable one without knowing if the feature-set is compatible with your arch.
### The license could change to nonfree for some options.
### NOTE: Some AUR helper may not like to change it just before building, so you can set those variables in your makepkg config.
### Related wiki page: https://wiki.archlinux.org/title/Makepkg#Configuration
