How do I select a webcam to use in Unity3D?

Question

Is there a way to select an external, USB based, webcam in Unity, rather than use the inbuilt one.

For example, I am using a Mac that has an inbuilt camera, but I want to use a high quality USB webcam in the Unity3D Editor for testing my project.  Is there a way I can switch between these two cameras?  I tried using the 'External' setting for the ARSession's 'FrameSourceType' but that just gave me the error 'only support mobile phone'.

Any help anyone could give me with this would be much appreciated.  I'm currently moving my workflow to use EasyAR :)

You can try change ARSession.cs: 97 from

var openResult = easyarCamera.openWithType(CameraDeviceType.Default);

to

var openResult = easyarCamera.openWithIndex(1);

Thanks for the help zhangpengar, I'll give that a shot when I get a chance and get back to you on whether it worked or not :)

This did not work for me either.  A dropdown somewhere to select what camera you want to use in the Editor would be preferred really.  Any chance of adding one it?  Also, have you got any more ideas?
