live video capture

[saman_artorious]

I wanna write a program to show live video with a RGB camera. (under linux)

Note that we should use a capture card. So, the capture card send me the video output. I don't yet know how exactly the capture card n its driver (there should be a driver i guess) works though.

So, how should I do that? shall I use qcamera headers available in Qt 5? (as I checked Qt 4 does not support qcamera)
if yes, how can I change Qt 4 to enable qcamera?

Here's a link, a camera example for Qt 5, can I use this code ?http://doc-snapshot.qt-project.org/5.0/camera.html
what do you think?


(I would thank if you give me detailed n exact information)
