This camera is 2-3 years old. It was relatively inexpensive, sold in many retail stores (Computer city, etc.). It was supposed to work with a non-standard driver if you could install it in 2.6.23-2.6.24, though I never tried it. I think the driver wouldn't compile under 2.6.25 (kernel changes), and it was pushed off to 2.6.28 until the general gspca driver became available. It looks like I've got the kernal configured properly because the proper drivers are loaded (gspca_ov519 & gspca_main) the kernel logs seem correct, and most importantly /dev/video1 is created. Reproducible: Always Steps to Reproduce: 1. Configure the kernel with the gspca driver and the OV519 driver. 2. Boot it. 3. Verify properly loaded drivers and one has new /dev/video#. 4. Attempt to use a program vidcat, mplayer, etc. to read from the device. 5. Device can be opened and and readable. Actual Results: All programs tried to date yield only "snow" (various colored lines across the image). vidcat seems to be able to capture a jpeg image. mplayer seems to be able to capture frames (that seem to have some low frame rate per second). Expected Results: One should be able to at least some program that can read the device and display reasonable images. One of the problems is that it isn't clear to me precisely what programs should or should not work under Linux to read the camera. Skype is installed on the machine but the net suggests that there are problems with the skype software and this camera so I have not tried to test it.

Created attachment 179570 [details] Loaded modules when camera fails It would be really helpful if someone could tell me what specific programs "should" be able to work with this camera.
Please install media-libs/libv4l and follow its postinst messages.
Serkan, you are a prince! I had already installed libv4l but have a layer of scripts on top of my emerges that keeps a record of what I installed, the log of the installation process and when it was installed and so I usually only look at the logs when they don't work properly. Since the libv4l installation worked without trouble and so I had not bothered to read about the necessity of having to setup the library wrappers around the video programs. The status now is that mplayer works quite well! vidcat and getjpeg less so. I get an image, but there are horizontal (interleaved) bars in the frame so one only sees effectively 1/2 of the frame (I'm wondering if the camera images are "interleaved" such that if one only captures a single image one only gets one frame? I tried to setup ekiga but so far haven't managed to make it work (though I've only worked on it a short time thus far). Skype will probably be my next attempt. Can you suggest any other programs that might allow linux-to-linux and linux-to-windows video conversations (meetings)? My deepest gratitude since trying to make the camera work on my machine has probably cost me days of googling, downloading and installing various software packages over the last several years.
This isn't a support forum. There is no bug here.
