I want to have multiple USB webcams running on a single Raspberry Pi. I will put them through a powered hub. I want the webcams to take stills simultaneously (or as simultaneously as possible - a second or two delay isn't a big deal) and save the images to a memory stick, each image will have the same name beginning but then
cam3 etc. to differentiate them from each other.
Is this possible? If so, what number of webcams am I limited to? Also, how would I address them, can
fswebcam control more than one webcam?
If it isn't possible, can anyone tell me why not?
