PC box, NVIDIA (GT740) - dual monitors - black box for comp USB source

This is killing me and I'm running out of time to fix - any help a big deal.
Event on Saturday & Sunday that requires me to stream.

Running EZGrabber for usb composite source capture dongle.

Window does not detect (if setting change can force would be great) - get control tools, not video window.
Source will not detect.

So running monitor capture. On single monitor works fine - but ugly and hard to control.
Dual monitor (one analogue) I get black box for video source window.

Have put performance as priority where can see to do so.

Halp!

Have just installed OBS studio - but no new joy.

@dping OBS Studio problem

You tried both OBS Classic and OBS Studio? Post your OBS Classic logs, I'm not very familar with OBS Studio yet, which is why I hang out here and not there.

And can you post a better problem description? I can't tell what the heck your problem actually is. What is your capture device, and you're having problems using two of them, or something? Hard to make out.

Hi - log from OBS not studio below.
Problem is that I have a video feed coming in through a USB capture device, displayed on a piece of software called ezgrabber. The video is working fine, can be seen.
But when I add the video to OBS I get a black box/window.
Am adding it to OBS as a monitor because OBS does not recognise the window that the video feed is displayed in, and also cannot see the USB capture device as a feed to add to scene that way.

So tl:dr black window in OBS on PC

Not sure, there's been other people with similar problems but few if any of them found a solution.

Do a google search for "EZ Grabber OBS site:obsproject.com". @Jim once said he was going to buy one, not sure if he did and if he did if he ever got it to work.

You may just have to get a different capture device that is known to work with OBS.

That's my conclusion too - cheap capture device with less than perfect drivers/software.
OBS can't open it as a source natively - which is really what I want rather than a workaround.
Hopeful that new capture device arrives today and achieves solid OBS integration.
