I would like to use Teams to conduct some distance learning classes. To provide a more professional experience, I am using OBS (Open Broadcast Software) to enhance the presentation and be able to switch among vdifferent sources seamlessly. I am using the Virtual Camera plugin for OBS and I am able pick that as a source in Teams but the quality of the feed is terrible, When I look at the same feed in Zoom - the quality is MUCH better. And when I look at the feed using the webcamtest.com website, the feed looks perfect. Does Teams downgrade the video signal for some reason? The quality of the Powerpoint capture is so low it is unusable.

Nat_from_LSL MS response to our problem was to remove the use of a virtual camera from Teams completely. Its almost a year later and still MS is silent on when (if ever) they intend to re introduce the capability.

How have you tested this? I ask, because if you're turning the camera on without Share and seeing this, you may just be seeing what is really the thumbnail in the tile where your picture is normally. I'm using a different virtual cam and broadcasting software, but I suspect this is your problem as I was briefly fooled by this. You'll probably need to use Teams Share to send the screen that OBS is controlling.Tmadel

Tmadel Looks like you are not the only one. There are a number of issues on the OBS forums as well. On my side, I've been trying OBS + Virtual Camera Plugin on Teams in 2 different setups with my surface pro 6: a) with a Logitech C920HDb) with a elgato camlink 4KI have the same issue in both setups, while the latency is passable for live calls and webinars (way better than my SlingStudio system), the video quality is almost unusable with virtual cam 😞 I'll do a few tests with other computers that are more powerful and/or dedicated to the video editing part and report back to you if it works. Let me know if you find a solution. Cheers! K

Hello Tmadel, I´ve open a idea in Teams Uservoice. If you want please vote for me? TeamsUservoice

Can you confirm that screen sharing via Teams (sharing the video output screen of OBS or similar encoder software app like WIrecast) results in better image quality than virtual camera.Also when there are are 40+ participants in a meeting? Al_Gray

I have the same pb; quality is very bad
It seems on the web forums that OBS virtual cam is hardly fixed to 1280x720
So I think that definitly, OBS virtual cam could not be used, except if Teams is limiting the video flux as well. Did you find another solution for the virtual webcam ?

  The best way was to have a 2nd monitor displaying the video output and share this screen in Teams instead of using virtual camera. The downside is that the framerate drops but the quality of fonts and details is better.

    erimo Do you even see an ODS window to share from Teams? I used to see an ECAMM Sharing window in Teams that was built for Zoom. It looks like I'm back to sharing a monitor (application, not display)

  philyves I think the problem is definitely with Teams. When I test the virtual cam output it shows as coming across at 1080p
