HDMI-RX DRM/KMS, Computer Vision -> HDMI-TX

[N0tiK44]

Hi all

I've been tinkering with my orange pi 5 plus(rk3588)
I've been trying to work on a render pipeline for a single system for as low of latency as possible.

My method was to utilize the HDMI-RX input to grab video straight to HDMI-TX to be sync'd between host/client pc almost instantly, at the same time using computer vision for object detection.
I've been having issues with DRM for (no module found) even after going through the config and enabling anything relevant
I haven't been able to use it as of yet and would like to know how i can
I've used plenty of media frameworks to achieve this but only 1-2 seconds latency is the best that can be done.
Can someone lead me in the right direction if said pipeline is achievable?

Thanks

I did have pretty much exactly this working with KMS sink a few months ago, I can't remember what I had to do to make it work. I'll try and dig it out and will post here!
