Ran into a couple of issues relating to video yesterday.  First, in the docs for the Camera class, it says getCamera() can accept a ‘name’ parameter specifying which camera driver to use.  As far as I can tell, this is not the case.  You need to use the camera name’s index of it’s position in the Camera.names array, and you need to pass the index as a string:

Camera.getCamera('2'); 

Also, it appears that Video.clear() does not really work, at least it didn’t for me.  It simply clears what looks like a single pixel in the top-left corner of the video object that the webcam was attached to.  I’m guessing at this point that it probably only works with flv’s that were streaming in, and not video from an input source.Â
