Title:
  Camera -  Microdia [0c45:648d] camera_test is unable to take still
  pictures

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  CID: 201203-10664 Dell Inspiron 7420

  On this system, the camera_test script is able to display video capture form the built-in camera. But it's unable to display a still image and multiple resolution images, the file size of temporarily stored file is zero. Causing the image viewer complain about "Could not load image" (screenshot attached) Or "Failed to validate image" for multiple resolution images test case. I tried to get more information from the script by adding "-v" to fswebcam command like this:
      def _still_helper(self, filename, width, height, quiet, pixelformat=None):
          """
          Captures an image to a given filename.  width and height specify the
          image size and quiet controls whether the image is displayed to the
          user (quiet = True means do not display image).
          """
          command = ["fswebcam -v", "-S 3", "--no-banner",
                     "-d", self.args.device,

  I didn't get any extra imformation, but both the "still" and
  "resolutions" test cases work fine with this.

  WORKAROUND: run "fswebcam --save OK.jpg -D 1"
