Most optimal way to stream between an opengl app and resolume

Post by sefreso » Fri Nov 08, 2019 23:40

Hello,

I have developed an opengl application.

I am able to "stream" it to resolume in 4K 60 hertz with alpha layer, using Spout.

Would anyone know if it is the most optimal way to do that? I do that so I can apply live effects on the rendering of the opengl app.

Would using NDI (both app on the same computer) be as optimum or even more? It's a nice thought since it would be the same code whether windows or osx.

Or any other idea?

The opengl app is too complex to be easily converted to a FFGL app, I'm guessing. It can't easily be ported in touchdesigner for example, see https://forum.derivative.ca/t/porting-a ... r/110124/6

Thanks!

Spout is always more optimized than NDI in every scenario.

Thanks for you input.

Now, if you had anything to share about how one can export frames out of spout into cpu memory this is where I'm at : viewtopic.php?f=12&t=19226

Sounds like you are having hardware issues not software. I can record several minutes at a time within resolume, or hours at a time with OBS. Might try upgrading your system.
