Capturing more than one webcam in one video file (avi)

Hi all!

I need to find a way how to make one video file from 2 or more webcam in C# (windows app). I tried to use the google for some samples, but no success. I found a way how to record a video from the webcam (with directshowNet, directx I can save two avi with two webcam...)

For example I have 2 webcams. I need to get the frames during the record, paste one frame near the other (make one image, create one frame from the two), and insert these new frames into a new avi.

Any idea? Is it possible to get the frames in time, and create one new avi from the 2 captured?
