Since I've been using Linux, I've been searching for a stable plugin to do some background removal in OBS. The royshil plugin, once compiled myself, did wonders using the GPU accelerated option, but at each update, either from OBS, the CUDA drivers, or the Nvidia ones, I had to recompile the plugin myself. It was a hurdle, especially as I'm using a rolling release distro.
So I gave this plugin a try, and it really delivers! It simply works without being a resource hog, and the settings are simple enough to still be able to fiddle with it to my liking. I'd give it 5 stars when I'll be able to have a sharp mask, for now it's always a bit blurry on the edges, even with the advanced parameters tweaked.
