VGA2USB video feeds

Hi,

In my app, I am using VGA2USB video feeds (http://www.epiphan.com/products/frame-grabbers/vga2usb-lr/). It is a capture card to capture VGA output from another PC and feed into my app as a camera through USB.

But when opening the camera I got this kind of generic exception

Could not start video stream
Could not setup graph
Error HRESULT E_FAIL has been returned from a call to a COM component.

This happen at line 585 of DirectShowCapture.cs under method StartupVideo.

Seem that the camera can't be opened.

I then test the device VGS2USB with VLC and the software came with the device called Epiphan Capture Tool. The device works just fine. I mean the apps can open the camera just fine.

Any clue on how to overcome this would be very much appreciated.

Thanks

Never mind, it is resolution issue. VGA2USB require 1024x768.
