Thread: Get capture device image

Hi, i am used to using v4l in linux to get images from my capture devices but i haven't been able to find a standard on acessing video devices under windows, so, how should i do that?

In the past Video for Windows was used. But now, IMHO, the current rage is DirectShow.

Also, if you're referring to VIDEO capture devices, there is a complete example in the latest DDK entitled vidcap.

Oh, thank you, that should be just fine.

By the way, does windows vista has support for VFW? As i can see in OpenCV source (computer vision sources) it uses the video for windows API, and it isn't working at my Windows Vista PC, i will try to fix that...

And yes, it is video capture device .

MS has stopped developing VFW way back when they released Win2K. VFW is a very old video driver architecture. Although it was supported up to XP. Also, to the best of my knowledge, Hauppage was the only card company to provide VFW drivers for XP. Therefore, I'd be extremely surprised if VFW is supported in Vista.
