I played around with the camera some more and figured out that it actually is working. I could see output from guvcview. Unfortunately, now I can't get the little popup window with MJPGstreamer. I can open the window from the url that's output by the script and see the classification. I don't know why it worked the one time, but not now. It's a puzzle.
