How do I view input from a PCI TV card

[mcclements]

I have a video camera which plugs into my PCI TV card and I would like to view the video on a VI front panel. How do I communicate with a PCI card? I am using LabVIEW 6.1

You don't communicate with the card. Instead you should be able to plug
into Video for Windows (if your card has an according driver) and access
the images from there.

Two libraries come to my mind here:

Pete Parentes WebCam library which is not just limited to webcams but
can probably access any Video for Windows capable device.

Irene He's IVision Library with a camera interface library to Video for
Windows devices:

If your PCI card does not have a Video for W
indows compatible driver,
you will have to call the shared library API which comes with it through
Call Library Nodes.

Hello,

I would recommend the first web adress, personally, for what you are doing. You can download the vis direct from that site, at no charge. A text file come with the download, explaining how to populate the LabVIEW functions pallette with your newly downloaded vis.

Thanks for that. I noticed that the VI only takes snap shots of the video output so I modified it to run in a loop. Unfortunetly all I get is a jumpy stream as this method misses frames. Think I'll just have to use the winTV software that came with the card but that just seems like I'm cheating.
