can't access webcams on surface pro 4 with captura #347

Open phobos6995 opened 5 years ago

phobos6995 commented 5 years ago

I already referenced issues #172 (I tried updating the drivers) above to no avail.

Here is what I get when I try to open captura:

System.Runtime.InteropServices.COMException (0x80004005): Error HRESULT E_FAIL has been returned from a call to a COM component. at System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 errorCode, IntPtr errorInfo) at Captura.Webcam.CaptureWebcam.RenderGraph() at Captura.Webcam.CaptureWebcam.StartPreview() at Captura.WebcamControl.ShowOnMainWindow(Window MainWindow) at Captura.Models.WebCamProvider.set_SelectedCam(IWebcamItem value)

Thanks in advance.

PS

I can access webcams with OBS Studio, and other screencast software. I don't know if that helps.

Does your webcam work with ScreenToGif. Captura's webcam code is based on it.

phobos6995 commented 5 years ago

I got exactly the same exception when using the webcam feature on ScreenToGif.

phobos6995 commented 5 years ago

The short answer is, no it does not work with ScreenToGif either. It sounds as if there is an issue with the COM port (?)

I'm not sure about the error and searching about it does not help either :cry:

I am also having the same problem :(.

Surface Laptop (Gen 1). I haven't been able to turn up anything on Google either...

OS: Windows 7 Pro 64-bits Capture Version: v9.0.0 beta Hi, this happens as well in Lenovo T570. Tested in Screen2GIF with the same result.

I'm sending the log file:
