Webcams are not displayed e.g. OBS Studio or Canon WebcamUtility

Problem: Webcams are not displayed
I’m trying to use the OBS Studio virtual webcams, but they don’t show up. Also the webcam from Canon (EOSWebcamUtilityBeta-WIN0.9.0) does not work. What can I do?

ActivePresenter version: 8.1.0 - 64-bit build. (Veröffentlicht: 2020.07.16)

OS: Windows 10 Enterprise 64Bit

Notes: The Cams are qorking in any other Software like MS-Tems, OBS Studio, etc.


ActivePresenter 8 uses the new API on Windows (since Windows 7) to support more new webcam models. However, the older webcam may not work because their drivers don’t support the new API.
Please search for webcam’s driver update and install it if any.


I use a Canon EOS 90D with the lates Diver (Beta) from Canon. The Camara was releast 2019, the drive is from 04/28/20.

Thanks for your information. Maybe these drivers still don’t support new Windows API yet, so the issue.
