Hello,
(My hardware: Lenovo IdeaPad U310 i7 with Lenovo EasyCamera)
I have upgraded from Fedora 17 with no problems. I installed needed programs such as skype(is installed correctly with all 32bit libs) and wanted to use video conference. In preferences I tried video, but I got just black image and no other signal (yes, there is the device found; "Lenovo EasyCamera (/dev/video0)". The same black screen I got in Cheese, and the same device is listed there.
Next thing I tried was "xawtv" and there was an image. It was laggy, with horizontal stripes, like there is an error with synchronizing the signal... (and image as well:![]()
)
my slusb log: (the 5986:0295 is the device I think)
my lsmode log:
I tried to reinstall whole system, didn't help.
I thied installing libv4l-0.8.8-3.fc18.i686 also,
and running skype like: (with error)
What can I do to fix this? I think, there is some kind of problem with decoding video signal, or syncing it, because all programs can find /dev/video0 device, but the image is just black. Notification led next to camera is on, when programs are using it, but with no image. (VLC shows nothing also, but can "use" the device)
Thank you for your help.
