I am not able to replicate this issue on my end. Locally, all virtualcam devices are showing exactly what I see in the preview at 1080p 60fps. Please provide log files from a session where this issue occurs.
Reminder, please make sure you are checking the local preview, and not the actual meeting output. Most conferencing software will automatically downscale the output to match connection conditions (which looks exactly like what is happening here).

Please have a look at it... whenever I select Tools > VirtualCam and select OK, the OBS crashes.
Where can I make suggestion for FR?
It would be cool if you could setup like a Default screen. I mean now if the OBS is down the camera displays a grey screen. It would be nice if we could like point at a jpg so it displays some logo or something instead of the grey screen.
Can this be done?

This crash has been present in the plugin for some time, I don't know what causes it, or how to fix it unfortunately.
I assume you mean Streamlab's fork of our program? I have no interest in supporting that.
This version is simply a repackage of an existing plugin. This is a good suggestion that is part of the RFC, and we are working on implementing a more native version of this plugin but it's outside the scope for this specific plugin.
Working for me!! WOW! Finally someone did it!@Jo909!
The plugin below was released a couple of days ago. It works for me.

Problem
VirtualCam shows up, OBS Camera shows up. but when I click to Start, OBS Studio crashes. This is with nothing else running and I do have 2019 Redist installed. 64-bit OBS Studio.
Search seems to indicate a possible issue with sources. The only things I have defined are an audio source (which isn't plugged in and I don't think VirtualCam uses?), the camera which is a Logitech external USB3 and a background image. No other media or anything defined.
Log is attached. As far as I can tell this is the only thing not working.

Ran out of time to edit.
So I got it to work one time by disabling the Logitech and enabling the built-in cam. But then - and this may be the whole 1080 thing I read about here - I get "Failed to start output". Doesn't crash, just doesn't start.
But no crash. So hopefully anyone else, this might be something to try to get past that problem.
Newbie here and could do with some help on a related issue. Virtual Cam worked fine on OBS and across platforms to Zoom and Discord. In building a scene Virtual Cam started using an image in my scene as a camera input result (??). Uninstalled all and reinstalled OBS and Virtual Cam, restarted and now, although Virtual Cam shows in tools, when I press start it shows grey - no camera input! What am I missing - should I somehow direct Virtual Cam to recognize my Logitec 920 as a source device. Running Windows 10. Please help!

You're still on Windows 10 version 1709, which stopped receiving updates for non-enterprise users early last year and is under active security exploit. Update Windows 10 the latest release build and see if the issue goes away.

Also having an issue with the VirtualCam plugin crashing my OBS like MrStackz. Log attached. Please help.

Your crash is the 'known issue' one that someone posted about before. But it seems to be related to Visual C++.
Did you install from this link? https://aka.ms/vs/16/release/vc_redist.x64.exe
And then reboot?

Update for everyone. I got mine working stable and consistent now.
Hopefully this table is of help to someone.
| PROBLEM | SOLUTION |
|---|---|
| VirtualCam not displaying as a menu option | You need to update both your OBS Studio and the OBS Camera version. The OBS Camera version I used has an early May 2020 release date, that one should work fine. |
| VirtualCam shows but won't Start/crashes when try to Start | Something has your default (As set in Settings --> Camera) camera reserved. Most common is Teams or Skype (which launch on startup if you don't disable it) or GoToMeeting or some other app, or it could be the browser. Close EVERYTHING, even stuff running on the bottom right. Then close and re-open OBS Studio and try again. If that doesn't work, switch your OBS Video source to a different camera and try Starting it. If that works it confirms that the other camera is locked; so you might try disabling it or unplugging it and re-enabling it and trying again. Goal is to get it unlocked so it can be used. (Annoying that OBS Studio crashes instead of just saying it can't use the camera.) Barring that, try to re-install all of the Visual C++ components from this link:https://aka.ms/vs/16/release/vc_redist.x64.exe |
| VirtualCam displaying gray screen despite starting | One thing I had to do was make sure that my Scene was outputting 1920x1080. It wouldn't work reliably at any other resolution. |
| VirtualCam error about failed to ______ output | VirtualCam got your camera, but something is still holding onto the OBS Camera you selected. Choose a different OBS Camera from the drop down and try to Start it, if it works you'll need to find which app has the OBS Camera chosen (see the list above) and terminate it, then you can go back and re-select OBS Camera. Or just switch your outputs to the new one you chose. |
| Web-based chat service can't find OBS Camera | At least in Chrome or Chrome-based browsers there is a setting you have to change. In the settings window if you search for Camera it will take you to a window where you can tell the browser to ask for permission, but you also need to choose the default camera from the dropdown. By default it will have your built-in camera or the latest USB camera plugged in. You can verify this is the issue by looking up in the address bar next to the Favorites star. If you see a little camera icon click it, and it will show you what camera and microphone the page is trying to access. After you make the change you will need to relaunch the browser and go back to the service and try again. When these web-based chat software companies don't code the interface to prompt you for a camera (like WebEx does), this is the symptom. |

I just did, and rebooted, but still crashing. Even when I've made sure the main camera is not locked. Any other ideas?
Hi,
i have the problem that the virtualcam dont show up in some tools (Cisco Webex, Camtasia). It works perfect in Zoom but unfortinuality i dont need it very often. Is there a solution? i tried to deinstall and reinstall a couple of times. Every time the same result.
I hope someone can help.

Okay, you're going to love this. I was finally able to get the VirtualCam to work. But with the stupidest thing.
Everytime I Started the VirtualCam with the "Horizontal Flip" option checked, it would crash. I finally tried that, thinking "how stupid would it be if it were just a single checkbox?" Lo and behold, it's running, and running well in Zoom and Discord (although Discord won't let me flip the camera horizontally, which is why I tried the checkbox in the first place).
Fenrir, something perhaps to look into ... why the horizontal flip is causing a crash?
Thanks,
WindyJ

Hi There, I've installed and am using this OBS VirtualCam plugin, however I am experiencing an issue and am wondering if I'm the only one or if this is a known issue?
The OBS-VirtualCam does not work with Microsoft Teams. The camera simply does not appear on the dropdown list.
It works with Zoom, though! Which is why I feel like this is unusual. Is there a trick that I'm missing? I have made sure that ZOOM is closed and that no other programs are using the camera when I'm attempting to use it in Teams.
Thanks for your suggestions!

Works fine in Teams Desktop. First thing I tested.
You might try uninstalling and re-installing Teams. If that doesn't work re-installing the OBS Camera with Teams not running.
Other than that no clue.

Not sure why that setting would crash but why not just flip your Video Source in OBS Studio before starting VirtualCam?
Then you can create a separate profile with it not flipped, in case you want to go back and forth.
