No video image Version-Release number of selected component (if applicable): How reproducible: Every time Steps to Reproduce: 1.Start any of the above mentioned camera softwares 2.View gray preview screen output 3. Actual results: Grey preview screen output Expected results: Preview screen output image of direction camera is facing Additional info: The camera I am using worked fine in those programs under Fedora 16. I made a clean install of Fedora 17 on Tuesday. ***The chosen component is a guess.***
Hi, Given that the same problem shows up in all the different programs you tried, this is likely a kernel problem -> changing the component to kernel. For starters, we need to know what camera you have, can you run lsusb in a terminal and copy and paste the output here? Regards, Hans
Dear Hans, This morning I plugged in a very old Logitech Quickcam for Notebooks Pro camera and it works just fine. The camera I am having trouble with (that I did not have trouble with last week on Fedora 16) is a RocketFish HD Webcam Model # RF-HDWEB. I am not sure who makes RocketFish products. The lsusb output reports that "Dynex" is the manufacturer, but the RocketFish website claims that Best Buy, who is the distributor of this product, is also the manufacturer. Here is the lsusb output with the RocketFish camera plugged in.

Hmm, that usb-id does not use any special driver, so likely it is a UVC camera. Do you know with which kernel version the camera was working in F-16? The best thing to do would be to install an F-16 kernel, download it here: http://koji.fedoraproject.org/koji/packageinfo?packageID=8 And then install it using: rpm -ivh kernel-.....rpm And reboot into that kernel. Then once you know what is the last working and the first non-working kernel, send a mail explaining your problem to the uvcvideo driver mailing list: linux-uvc-devel.de
I really don't know what kernel I was using when the camera was working. It's funny how, for most people, when things are working fine we don't document, but when things go wrong we wish we did. I briefly glanced through the list of kernels on that page you sent and didn't see any PAE kernels. I'll keep looking.

I'll keep looking. The PAE builds are part of the regular builds. For starters I would try a 3.2.x build for F-16 with your F-17 system, ie: http://koji.fedoraproject.org/koji/buildinfo?buildID=307526 Regards, Hans
