I would like to capture the live video with two USB webcams (Philips SPC 900NC), but I found that they cannot work simutaneously on my laptop. Either of the two USB webcams could work alone or work with another webcam (mounted on my laptop originally).
When I use the simulink block 'From video device', Matlab gave the error message with ' Multiple VIDEOINPUT objects cannot access the same device simultaneously.'. Then I checked the video input device with command 'imaqhwinfo', only one of the USB Philips webcam could be detected.
I would like to know that,
1. what's the reason of this situation? is it because the hardware limitation (USB bus bandwidth) or just matlab video object don't support same multiple video devices?
2. what's the solution of this? could anyone give me some suggestions?
thank you very much.
