** Description changed: 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 + I didn't get any extra information, but both the "still" and "resolutions" test cases work fine with this. + + 201202-10404 Inspiron 5720 - 12.04.2 Precise (3.2.0-48) : Same issue, "-v" tweak works too. + T: Bus=01 Lev=02 Prnt=02 Port=04 Cnt=02 Dev#= 4 Spd=480 MxCh= 0 + P: Vendor=0c45 ProdID=648d Rev=1c.07 + S: Manufacturer=1234567890-17V + S: Product=Laptop_Integrated_Webcam_HD + + And usb-devices output from 201203-10664: + T: Bus=01 Lev=02 Prnt=02 Port=04 Cnt=02 Dev#= 4 Spd=480 MxCh= 0 + P: Vendor=0c45 ProdID=648d Rev=1c.07 + S: Manufacturer=1234567890-17W + S: Product=Laptop_Integrated_Webcam_HD WORKAROUND: run "fswebcam --save OK.jpg -D 1" ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: linux-image-3.5.0-34-generic 3.5.0-34.55~precise1 ProcVersionSignature: Ubuntu 3.5.0-34.55~precise1-generic 3.5.7.13 Uname: Linux 3.5.0-34-generic x86_64 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.25.
