Resolume eating all GPU memory, Spout, Directx9

[sefreso]

Hello,

I tried enabling "DirectX 9" in the "SpoutSettings" app.

After restarting Resolume, I can see in Task Manager that it is slowly eating all GPU memory even though all my clips are empty.

If I disable this option in "SpoutSettings" then memory usage is normal.

Any idea?

Thanks

That's a bug we're working on. (#11934)
I'd recommend disabling directx 9 Functions, and using and GPU Texture mode.

Thanks!

Do you have a link to (#11934) so I can track its progress? Or is it a private bug tracker?

Is there anyway also for you to tell me which method is employed in the latest version of resolume in order to copy textures from gpu to cpu memory in the record feature?

Thanks!

It's indeed in a private system, but if it's fixed, you'll find it in the release notes.

Recording inside Resolume is not based on Spout.
The textures are copied from the GPU memory to the RAM, then compressed by the CPU to PhotoJpeg.

The textures are copied from the GPU memory to the RAM

Is there anyway to know how this process is performed? glReadPixels? Using a PBO and a memcpy?

I'm trying to implement a recorder to record more than 15 seconds and keeping the alpha layer and I'm failing to download textures at max bandwidth capacity.

Thanks!

No idea.

Maybe you can use spout forced to Shared mode, to have Resolume put the texture into the RAM right away and grab it from there?

Have you tried this one? https://www.lightjams.com/spout-recorder.html

Lightjam doesn't record the alpha layer.

Spout shared mode uses PBO + memcpy which suffers from the same issue I have.

Would you kindly ask someone in the dev team?

Spout shared mode uses PBO + memcpy which suffers from the same issue I have.

Resolume uses the standard spout libraries for spout, so would do the same then.

[sefreso]

As you mentioned earlier Resolume does not use Spout for the record feature so It's not using the same means.

Would you please forward this question to someone in the dev team?

Thanks!

Done

If you have a mac available, Syphon recorder can record alpha.
