Issue with Camera Compatibility and MediaDevices API on Windows 11 in Zoom Web SDK

Video SDK
1

Hello,

I’m encountering a camera compatibility issue when using the Zoom Web SDK (v3.11.0) on Windows 11. The problem arises when trying to access a video stream via the MediaDevices API (getUserMedia()), which is used to initialize the camera for video conferencing.

The issue is specific to the Basler acA2040-55uc, a USB 3.0 camera:

  • On Windows 10 and earlier versions, everything works perfectly.
  • On Windows 11, the camera fails to start the video stream, resulting in the following error:

NotReadableError: Could not start video source

Other standard USB webcams work fine under the same conditions, but the issue persists with the Basler camera on Windows 11.

Here are the details:

  • Camera Model: Basler acA2040-55uc (USB 3.0 camera)
  • Operating Systems Tested:
    • Windows 10: Working as expected
    • Windows 11: Error occurs
  • Browsers Tested: Latest versions of Chrome, Edge, and Firefox
  • Zoom Web SDK Version: v3.11.0
  • API Used in Web SDK: MediaDevices API (via getUserMedia())

We’ve found a workaround: when the camera fails to initialize, we alert the user to disconnect and reconnect the camera. After reconnecting, we call getUserMedia() again, and the camera works properly. However, this is not an ideal solution as it disrupts the user experience, especially during live meetings or conferencing.

Has anyone else encountered this issue with USB 3.0 cameras while using the Zoom Web SDK on Windows 11? Are there any known fixes, configuration changes, or SDK updates that could help resolve this problem?

Any guidance or suggestions would be greatly appreciated!

Thank you in advance for your support.

Hey @Steven_Aziz

Thanks for your feedback.

Could you test your camera device on the official WebRTC platform?

Thanks

Hi Vic,

Thanks for the suggestion! I tested the Basler acA2040-55uc camera on the official WebRTC platform, and unfortunately, I encountered the same issue—when trying to access the video stream, the camera fails to initialize, resulting in the “NotReadableError: Could not start video source” error on Windows 11. The camera works fine on Windows 10, but the issue persists on Windows 11, just as with Zoom Web SDK.

It seems like the problem is specific to Windows 11 and this particular camera model, and it might not be isolated to Zoom’s SDK.

Let me know if there are any additional steps or settings you recommend!

Thanks again, Steven
