Memory leak on capture device

[judicator]

Hello! Yesterday i notice what when i activated ugreen hdmi capture device Resolume start eat memory. Its strange because what on another video capture device i dont have same problem, only on ugreen capture deivce
Attached video and screenshot with problem.
Check this capture device on another laptop with Windows 10 and Resolume 7.16.0 - dont seen memory leak.

Resolume Arena 7.19.2.33366
Windows 11 Home 23H2 (22631.3527)
ASUS ROG Strix G18 G814JI
CPU: Intel Core i9 - 13980HX
GPU: NVIDIA GeForce RTX 4070
RAM: Kingston FURY Impact [KF556S40IBK2-64]

There was a similar issue about a year ago with BlueAVS cards, (I believe it's the same chipset as the uGreen). I actually have that exact same card but haven't used it yet.

I'll try to recreate the issue today on my end using that card (home sick anyways) to see if I get the same results.

I know the BlueAVS issue was fixed a month or so after the issue was reported so I'm not sure why this would be happening now?
I'll report back in a few hours.

Thanks! I found information, what this device got MS2109. So may be its can be helpfull.
Also i can update Resolume on my previous laptop for same last version and check this problem on Windows 10

I do know that the BlueAVS issue was isolated to Win11 only as my Win10 machine was working fine. I just started the test. Should know something in an hour.

To confirm, we're talking about system memory and not GPU memory, correct?

I just ran a test for a little over 30 min with no issues. The bug in the past would leak about 10Mb every 30-60 seconds. I've been sitting at the same system stats with only about a 10-15Mb fluctuation (it always returns back to the original noted stats.)
This was done using a 4080 Razer computer with an i9 and 64Gb of system memory running Win11. All drivers and OS is up to date.

First time actually using this card (bought it as a spare) I did have to manually change the resolution in Resolume as it showed 1080p but was actually inputting an 800x600 with a uGreen logo behind it, Once i changed it from 1080p @50, to 59 back to 60 the image fit the entire screen as you would think it would be default? So that was weird but in terms of stability and memory leak's, My system is showing stable.

Okay, i update Resolume on my old laptop to last version on Windows 10 and can say what this problem only on Windows 11, on Windows 10 all worked well. Also i notice, what if i change capture resolution and select lower capture resolution - memory leak is stopped! Its same situation with cheap HDMI capture USB device (like cheap RULLZ devices).
I will attach video.

If you could, could you go to the feedback tab in the Resolume preferences and send a Log file report to the dev's (be sure to include your contact info). I think they would love to see that info to see if there's an issue they overlooked?

I'll try to re-create that test again but this time I won't change the resolution of the capture card to see if I can recreate the issue.

Thanks for the info

Oh, i forgot about this option. Send to developers information with log file report. Now wait

I re-did the test without changing the resolution on the device and got the same results. All good on my end. No memory leaks.
BUT, with this device, I get this no matter what until I change the resolution to @59 back to @60 (And I can't turn off deinterlaced):

(And I can't turn off deinterlaced):

This 'Deinterlace'-option will be hidden instead of greyed out with a future update (probably 7.21) when we don't support deinterlacing with that card.
