Delay camera input to output

hey guys
i have a project coming up in april where they gave me a challenge. So far i don't have found a solution.
i will get a live camera input on my bmd decklink recorder 4k. What they want is to output that input source with a delay of approximaly 30 seconds. The input will run all day.
The idea is a camera filming people coming into a room and project that camerafeed with delay as people walk around the corner and see on big screen themselfs entering the room +/- 30 seconds ago
Is there any possibility to do that within resolume R6 arena?
Or do i need some external equipment, if yes .. what equipment or software?
Thanx

If you on win, you can try vMix or OBS (crossplatform), looks like they both have delay feature.

You could try multiple DelayRGB effects.
edit: tried it on my macbook, 9 delayRGB effect with RGB parameters set to maximum I got around 20 seconds delay.
on a 720pcomposition, this was pretty heavy on my mac with occasional stutters.
Decklink to OBS to VLC to NDI to Resolume could work better

syphonspout in TOP (or ndi in TOP) -> Delay CHOP -> syphonspout out TOP (or ndi out TOP) in Touch Designer

I second the TD option. There is a delay in resolume's advance output but it's only good for .1s

I've been doing some testing in TD and here is what works great:
syphonspout in TOP (or ndi in TOP) -> Cache TOP -> syphonspout out TOP (or ndi out TOP) in Touch Designer
Set your cache TOP as follows to get a 30-second delay at 60fps:

Second this solution but I would capture inside touch designer instead of capturing in resolume and using spout. It supports the same blackmagic sdk I believe.
