A plugin that could be great, unfortunately it only supports FIXED sizes/dimensions, not relative ones. Let me explain:
I'm displaying the current music image cover. They're not all the same size (depending on what's been put in the MP3...).
To fix it, I set the size to 100x100px using OBS's transform function. If I add a mask via advanced-masks, it won't work because it works in pixels of the base image (image size changes with each music), not on the image already resized to 100x100.
I don't know if this is understood, but it would be cool to be able to work in relative percentage and not in actual pixels, to work on potentially resized images at the same time <3
