A black screen is displayed when I activate my camera

The same issue over here. We are using a Fujitsu Lifebook U Series built in Video Camera (FJ Camera).
Video is black with Zoom Client Version 5.11.11, but Camera light is on.
Any other Client (Skype, Teams, GotoMeeting, WebEx) works as expected. Just a Zoom problem.

Workaround: Join the meeting via Webbrowser (Firefox).

I have a particular problem. I used to participate in meetings on Zoom and I could display my video without having a personal zoom account. A few months ago, I opened a zoom account and created a meeting. By mistake, I checked the "Stop my video when joining a meeting" box in the camera settings. After that, when I activated my camera during a meeting, the camera was considered activated but only displayed a black screen. In Windows 10, in the camera privacy settings, my camera (an integrated webcam) was seen as currently being used by the Zoom app.The problem remained after of course unchecking "Stop my video when joining a meeting" in the camera settings, restarting the computer, downloading the latest version of Zoom, stopping my Zoom account. I have left the problem alone by joining Zoom meetings with a black screen as video while the video works using other applications like Teams.

 

Has anyone experienced the same problem? I would appreciate any help.

Hi christian I too had the same problem but when I checked antivirus permission, in my case k7 total security the webcam permission is denied. So I disabled it permanently and it worked 

Same issue here. Logitech webcam on an Apple Mac Mini with M1 chip.

The camera light turns on. I can see myself in other applications, including Logitech's own LogiTune app, but Zoom shows my video as completely black.

Interestingly, uninstalling and reinstalling Zoom seems to resolve it for a short period, but then it fails again. 

I have got the same problem.

Problem was resolved after I switched off zoom virtual background since the one I was using no longer exists. 

I have the same problem, what works for me was, uninstalling zoom, then install zoom (32bits) , Then go to the antivirus , in my case is kaspersky, go to trusted apps. Add zoom as trusted app. Then reboot. And it work fine. 

just stop your anti virus, especially kaspersky... just pause it, and try using your cam on zoom.

For me it was Avast webcam shield - for some reason, Zoom was on its block list.

My problem was that was only happenings on one particular WIFI network - I could not duplicate it at home or elsewhere. So i don't think it's the antivirus on my PC (and in any case, I don't have Avast or Kaspersky.)   

- The bad news is, it finally happened to me on a second Wifi network. Perhaps if I could get technical details on those two networks, I could see what they have in common that might be the cause, but the folks at each location were not eager to share information - perhaps they thought I would use it to hack their networks?

- However,. the good news is - if I join a meeting from my browser, it doesn't happen - the camera works as expected.

So still a mystery, but at least I have a workaround (that works for now...) 

I had the same issue where the (integrated) camera was activated and its small light was on, but Zoom would only display a black screen where my image should have been. Others on the call could also not see me.

I use both Zoom and Teams for meetings, and my camera worked fine with Teams.

What seem to have solved the issue for me was quitting Teams altogether. I did this during a call where my video was not working. I turned the video off in the meeting, force-quit Teams, then turned Zoom video back on, and it miraculously worked.

Lots of issues with Teams these days, worth a try if you are having the above issue.

Not sure if this resonates, but I've been able to mitigate the problem by opening the PhotoBooth app on my Mac. 
So here's what happens: I open Zoom, my USB Webcam stops working. 
I open photobooth, it starts working again, even for zoom.
If I open PhotoBooth first, then open Zoom, it stops working.

Why is Zoom specifically shutting off my webcam?
