How might I route video through another program, then back?

[Agent Orange]

Looking to use some of the Processing and Touchdesigner effects I've made with Resolume.

I have Spout set up, and it's great for sending frames one way.
Resolume will send its output to the other software, but after processing it, I'm not sure how to bring it back into Resolume for final output. Doing so will draw over the output that's going to TD/Processing.

What I'm looking for is similar to an send effect in audio.
Resolume -> Processing/TD -> Resolume -> Output

Is this possible?

You can use spout back to Resolume.
Your sender will appear in the Sources panel.

Touch designer

Spout top in and then spout top out. Shows up in resolume as a source. It's actually pretty darn easy.

Here is a TD comp with both syphonspoutout and ndiout TOPs from the same syphonspoutin TOP source.

Thanks for the replies guys,

Spout in and out in TD isn't the issue. The problem is how to route that once it's back in Resolume, to be used as the final output. I haven't been able to come up with a way that is completely separate from the composition I'm sending into Touchdesigner in the first place. Routing the entire composition results in TD's output becoming its own input, which makes a feedback loop that doesn't really get anywhere.

The setup I tried that somewhat works is to route one layer out over syphon, in advanced output. That gets processed in TD, and brought back in using a spout source clip in the top most layer. Problem then being the original output is still visible underneath the TD output.

Make a group with everything in your composition besides the TD layer
Turn the group opacity off
Choose that group as the input source for a Slice in a dedicated Screen in the advanced output
Make sure you uncheck Input Opacity for that Slice
Choose Spout as the Device for the Screen
Do your think in TD
Create a layer on top of the group with a Spout Source selecting the Spout stream from TD
Lock the layer when the Spout clip is triggered

That should do the trick!

It would be awesome if someone made an FFGL plugin that both sends and receives to and from Spout/Syphon. Would make this sidechaining stuff a whole lot easier.

Thanks @oaktown, looks like that gets the job done.
