Question / Help Multiple aspect ratios in one streaming session. Is there a plugin for crop-detection / auto-cropping a source?

I stream videos of different aspect ratios, they range between 4:3 and 16:9.
My base resolution is 1440x1080 as most of the videos are in 4:3 and this provides the fullest image, but I'm using a 1920x1080 display capture source and some of the videos have black bars encoded into them.
Currently I have to scale and position the source between each video, but if I had a script that automatically detected what needs to cropped, applied it in a crop filter, then applied fit to screen, then that would save me a lot of bother!
I've used ffmpeg's cropdetect before for similar purposes in video encoding, but I'm not exactly sure how I'd go about it during a live stream in OBS.

Any ideas?
