Switching between 2 cameras very rapidly (in c++)

[Unregistered]

Hi,
I'm using the DFG/1394-1 Firewire-to-Video Converter (referred to as device) to do some image processing. In my application I have to use two cameras (which I connect to comp0 and comp1 of the device). Although there are two firewire outputs on the device, I believe that only one of them outputs the camera signal.

The problem is that I need to switch between the two camera as many times i can do in a second. Say the goal is to get 5 frames from each camera in a second ( if possible). I noticed that even after stopping the live feed there appears to be some images in the buffer from the previous input channel.

I would like to know how quickly the input channels can be changed/alternated, without messing up the live feed. Also pointers to any sample source code (in c++) for the same application will be of great help.
Thanks
VV

Hello,

You are right, the converter can handle only one video signal at the same time. There is a multiplexer that switches the inputs.
With IC 1.3, you will get probably one image from every of the two cameras. With IC 1.4 it may be possible to get a little bit more (maybe 2 images from every of the two cameras). We have to make further tests to verify this.
5 images from every of the two cameras will not be possible.

Best regards
