I have a logitech HD Webcam C510 (046d:081d) and I am using openSUSE 12.1 64bit. The webcam is supposed to be uvc compatible. The weird thing is that some applications show video from it while others cannot.
Specifically, these applications work: kamoso, guvcvideo, luvcview
These do not: cheese, skype (2.2), kcm_phonon’s webcam test,
Cheese gives the following error:
libv4l2: error turning on stream: Input/output error
** (cheese:7316): WARNING **: Error starting streaming on device '/dev/video0'.
** (cheese:7316): WARNING **: Could not negotiate format
kcm_phonon gives a similar error:
libv4l2: error turning on stream: Input/output error
Any idea what might be happening?
