Hello Christopher, For comment #5, I want to prove that this issue only happen on a specific revision of this webcam, which is revision 1c.07, therefore I think maybe we can nominate series for this?
** Summary changed: - Camera - Microdia [0c45:648d] camera_test is unable to take still pictures + Camera - Microdia [0c45:648d] rev 1c.07, unable to take still pictures with camera_test (fswebcam) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1194761 Title: Camera - Microdia [0c45:648d] rev 1c.07, unable to take still pictures with camera_test (fswebcam) 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.
