Image from a camera using a video converter to USB

[Identcor]

I tring to capture in my LabView app the alive image of a camera that is transmitted to a Tv tuner. I´m using a video  converter to USB (PC) I don´t need to process the image I just want to see the image of the camera alive.

When I use a Microsoft LifeCam (usb) conected directely to the usb port I can see the image in my app.

When I use Windows Movie Maker to see the image of my remote camera I can see the image alive.

But, when I use my app with the remote camera it doesn´t work. I can´t see the image.

My app is is attached bellow. As you can see I´m usig Imaqdx and LabView Fall 2011.

Someone could help me?

Thanks in a advance.

Is your device DirectShow compatible?

Dear Christian,

I don´t know if my device is directshow compatible. May be not, because I tried to see the image using NI Measurement & Automation and I couldn't, besides the device appears in NI-Imaq devices list.

But before this Labview app I made the one that is attached, using labview 8.6 and Imaq for USB. It woked right but because of the property page object every time the app ran a window was open and no matter was checked ok or cancel it worked in the same way. I thought using Imaqdx objects I didn't have this undesirable window. Do you know why it worked using Imaq for USB objects and it didn't using Imaqdx objects?

Thanks in advance.
