If you turn on the camera to record in surface pro 5, the program crashes when you turn on the camera at one point

Is it a dual camera problem?

That's an issue that I'm getting report from users with Windows 10.
Still not sure what could be it.

Do you get any error message when this happens?

Have you tried to open Event Viewer to check if there's any error message in there? (In the Windows Logs > Application section)

ScreenToGif/ScreenToGif/Webcam/DirectX/CaptureWebcam.cs

Line 474 in fa78813

var hr = CaptureGraphBuilder.RenderStream(cat, med, VideoDeviceFilter, _baseGrabFlt, null);

This line returns E_FAIL. I'm on a Surface Book 3 (which has 2 cameras - or 3 including the IR camera).

Couldn't figure out how to step into the COM method, so that's as far as I can go unfortunately (for now).

I tried to connect an external camera to my surface pro 4 and it worked well. Only the internal front and rear cameras crashed.
