This issue has been around for years, The only solution I've found online is renaming camera's through the registry, but that doesn't actually work. If you have two webcams with the same name, Capture.list(); will list them, but you can only get the first instance.

In this example I happen to know that the 3rd and 48th camera's are:
"name=Microsoft LifeCam HD-3000,size=1280x720,fps=10"
But since list() just produces an array of Strings, assigning the camera's to new captures just grabs the first camera with that name.

void getCamysByIndex() { String[] cameras = Capture.list(); if (cameras.length == 0) { println("There are no cameras available for capture."); exit(); } else { cam[0] = new Capture(this, cameras[3]); cam[0].start(); cam[1] = new Capture(this, cameras[48]); cam[1].start(); } }
I'm using this to count standing bowling pins. Right now I can get by just fine with two different brands of camera, but it's not very extensible. Seems like there should be a better way.
