WebCam Preview Very Jerky With Logitech C920e

[Neil N]

This can be duplicated in the Telerik UI for WPF Desktop Examples app.

One of my clients uses a fleet of Logitech C920e cameras to capture photos.  The RadWebCam's preview is very jerky and severely lags behind camera movement on every kind of computer we've tested (all running Windows 11) .  This issue isn't present with the couple other camera models we've tested.

I've tested other webcam photo capture apps on Windows 11 and they all work fine with this camera (no lags, no jerkiness).  This includes DevExpress's "Outlook-Inspired Application" demo WPF app.

Hi Neil, I don't have this exact camera, so I can't properly test the problem, but here is a suggestion that you can try. You can use the RadWebCam API to list all video formats supported by the camera and test with different formats. If any of these work better compared to the auto-selected format, then you can use this when the camera is Logitech C920. The following article shows how to manually start the camera with a different video format.

There were 328 video formats. 😶  Luckily, I started at the end of the list and the second format worked.  Thanks again.
