OBS keeps misplacing my camera!

[UUBill]

Setting up OBS for the first time, here, and OBS is losing connection to one of my cameras.

Two Cameras:

• CAMERA 1 is a USB webcam. This is working fine.
• CAMERA 2 is the "problem child" ... an older Vaddio PTZ camera fed through a Magewell USB Capture HDMI Plus. It then comes into a new Dell tower via USB 3.0 cable.

Here's the issue. I can set up both cameras as sources in several scenes. It works great. But when I shut down OBS and later start it back up again Camera 2 is black. No image. Camera 1 (the webcam) is fine. I don't lose it.

I can then unplug the USB cable and re-add that PTZ camera as a brand-new source. It works great. No, I can't fix the old source via properties. I have to add it all over again as a new source.

Needless to say, I don't want to have to add that camera to each scene it's in, every time I boot up OBS. Ideas? Suggestions?

Thanks,
Bill

From the description of the problem I can assume that you trying to use the same source in multiple scenes. Try to add the source as Add Existing (or copy/paste as "reference") when you need it in other scenes.

More about the sources and referenced copies:

Bug Report - Duplicating Group does not do a deep copy - objects within copied group are not duplicated but referenced

What happens? Copy Group >>> Paste (Duplicate) >>> change element in group >>> element in original group changes as well I guess duplicating a group in OBS does copy the group object itself - but the elements within are still referencing their original objects and therefore the...

Yes, I tried that too.
OBS can’t even see the video from the camera at all, unless I unplug the USB cable from the computer, and plug it back in.
Even when I do that, it doesn’t assign that video back to the source. The other thing to know is that the camera name that comes up is the same as it was when I first added those sources.

Then,

Please post a log with your issue! Here's how...

OBS Studio creates a log file each time you run it which contains very useful diagnostic information. Without a log file, it's much harder for any support volunteers to figure out problems and your post may be ignored. To upload a log file, go to the Help menu > Log Files > Upload Last Log...

Ok, you asked for log files. I don't have daily access to the computer, so pardon the delay. I have two logs:

1. The first time I launched OBS and it didn't find the camera (Video Capture Device): https://obsproject.com/logs/8BiB2vv0Zh1EGdfb
   
   
2. I quit OBS, and then immediately started it back up again, and the camera was there:

So, I guess this problem is intermittent?
Thanks.

Again, in Windows you can't get second digital stream of the data from the device. Device already in use.

Just remove all instances of the same device Source from all scenes and add it to only to one scene (set all required properties) and then add it again where you need it but only as "Add Existing" or copy/paste "reference".

Oh! I get it. I’ll try that.
Thanks so much for your help!

@Suslik V it worked. Thanks again!
