Camera showing Black Screen only when using Teams app, works with Web version
Hi guys,
A client is using Windows 10 x64 running v1909 on a MacBook Pro 13" (2019, 4 Thunderbolt Ports) and oddly enough the Teams app now shows the Camera as a Black Image as the Preview. It's listed in Device Manager as FaceTime HD Camera. Zoom and Web Teams works completely fine. Even opening the MS Store Camera App loads the Camera fine. It's just isolated to the Teams App, I'll list what I've tried already below, really hoping you can help in any way.
-Re-installed Teams x64
-Attempted to install Teams x86 - No change
-Removed Camera Driver and re-installed via Bootcamp drivers
-Re-installed ALL Bootcamp drivers from the latest available updated
-Cleared Teams cache folder
-Office Quick Repair/Full Repair
The problem still exists but only with the Windows app version of Teams.
If you have any ideas or thoughts please let me know.
Thank you,
Harminder
I have been having this issue as well and have found a hacky solution. It seems that when you initiate the camera in Zoom, it stops it from working in Teams. The only way to get it working again in Teams is:
1) Reboot into Mac
2) Download/Open Teams app on Mac
3) Initiate camera (either start a video call or test camera in Teams > Settings > Devices)
4) Reboot into Windows and the camera on Teams should be working again.
HOWEVER as soon as you start the camera on Zoom again (also seems to happen with Google Meet), it will stop working on Teams and you will have to repeat the process above.
It seems using the camera on Zoom/Google Meet causes the camera to become incompatible with Teams (and also Skype). Hopefully an actual fix to this is coming soon
harminderchagger we are chasing MS for many months for this issue and finally have the solution. see if that works for those who are using MacBook with windows 10 boot camp option. follow the below steps:
- Quit Teams application completely
- Start cmd as administrator
- Run this command echo {"RtmCodecsConfig":{"CapturerApiForce":"1"}} > %appdata%\Microsoft\Teams\SkypeRT\persistent.conf
- Verify that %appdata%\Microsoft\Teams\SkypeRT\persistent.conf was updated as expected.
- Start Teams again, and test the camera.
Cheers!!

TechManish This solution worked for me, many thanks.
@TechManish This solution worked for me as well, many thanks.
TechManish Your solution worked perfectly.
I had this problem, Windows 10 with Bootcamp, MacBook Pro 2019 model, and your echo command that inserted this into the persistent.conf file is what worked to fix it.
Thanks for the fix... I've had black camera in Teams for months, while all other teleconference apps, the windows camera app, and the Teams web app worked fine. Only Teams Windows App showed the camera enabled, but black and no video. Following your instructions by closing out Teams completely, running the echo command, and restarting Teams and the video came up. This was without having to boot into the Mac side, or having to reboot the machine, or do anything else.
- you saved me 🙂 thanks

raphajThanks!
I traced back my meetings and indeed this happened after a google meet meeting using a webcam.
Rebooted to mac os, started the webcam in teams. Go back to Windows, and indeed the camera works again.
I can hardly call that a solution, but knowing that this can bring it back is good. Thanks!
Thanks for trying this Jan, glad it's working again albeit in a strange way. I'm guessing its not going to be anytime soon that Microsoft will be able to fix this. Jan Driesen
Amazing little hack there! I'll give this a go at some point this week with the client. Very weird behaviour but at least you've found a way to replicate this behaviour so its sort of a fix.
Thanks for your effort 🙂 raphaj
Same thing. MacBook Pro 13'' 2020 4 Tunderbolts.
Only Teams showing the camera as a fully black image, all other apps using the camera are working.
Win 20h2. Teams 1.3.00.28779 (64-bit).
Reboots, reinstall of Teams, reinstall of drivers... Nothing helps.
Worked fine up to now.
- Make sure to report this via help-> Feedback in the client!
Adam Jan Driesen Thanks Jan. I'm not going crazy in that case. The user said she was running it fine up until this point too. I've restored Windows Update back to v1909 from v2004 but it didn't help. Looks like something permanent has been triggered. I tried an older version of Teams too (1.33 I think) but this did the same thing. adam deltinger Thanks for this mention, I've done this now. I'm hoping it gets somewhere but for the user will just have to use Web Teams as a workaround for video calls.
Thanks for the input though guys.
I have this running teams on VMs like crazy. All other apps work fine. What is wrong with MS Teams?? How are we supposed to rely on this service if we can't even use our webcams??
- Hello to everyone. I solved my problem by changing the zoom settings
Open zoom>settiings>video>advanced>video capturing method> Media Foundation (non auto nor Direct show)
Restart the system in mac os test camera then restart to windows...problem Solved!- Changing the setting to Media Foundation is what worked for me. Thank you for sharing.
hey man,
A user on my end has been having the same issue. also tried reinstalling teams and the webcam driver but unfortunately still the same issue.
have you tried the "windows support" software from apple.
harminderchaggerHi Ruben-D unfortunately yes, I got a USB made up of the Windows Support Software from Mac OS and tried to perform a Bootcamp repair, it still didn't work unfortunately. Pretty weird issue, I've submitted the Help>Feedback now so hoping for something along the line.
Hope we get a fix but at least in the meantime there is the web version.

I did an update of MacOS, then created the USB driver set. After running the bootcamp repair in Windows, the issue disappeared. I'm not sure whether this was caused by the OS update or the repair of bootcamp. Since installing Windows, I had never booted MacOS, so it is unlikely that the cause of the issue was in MacOS.
- Hi @All,
fyi
problem solved: i had the same problem untill last friday 26.02.2021
today a made a few windows restartes and installed the last updates. now it works again. You may try the following steps to fix the issue.
- Log out of your Teams account.
- Launch the Task Manager and locate all Microsoft Teams processes running in the background.
- Right-click on each process and select End task.
- Close the Task Manager app and launch Teams again.
If it it not working, you can just try update the program or just uninstall and reinstall the program itself to see if the issue persists.
I have the same issue. What worked for me is deleting my camera driver. For some reason while deleted, the video started working in Teams.
It's not a permanent fix as it goes back to black one the driver is automatically reinstalled.- Same Problem here. Using teams on macbook M1, 2020, Big Sur.
