MediaCapture 90fps and 120fps video capture

Messagepar breckjensen » 16 Nov 2017, 06:12

Hi
I have a working app that capture video frames to detect motion. It works fine when selecting 60fps . I am measuring frame rates using Stopwatch class.
When selecting higer frame rates, using available profiles where denominator and nominator combination provides 90fps or 120 fps, the capture rate goes down to 45fps or lower.
It is as if the webcam does not register the speed request. (I have also looked at the CPU usage, and there are enough resource left to run faster).
I used the Logitech Brio Webcam and also another webcam with 120fps capabilities. Both has the same issue of going slower when requesting faster speeds.
1) Is there a FPS limit in UWP or is there a solution for this?

Please help.

Thanks!

I didn't find the right solution from the Internet.
