[pschonmann]

Binary package hint: cheese

I have webcam, labtec webcam pro. Im able to switch between 640*480 and 320*240, only 640*480 has problem. On /dev/video0 i have dvbcard. In gconf-editor i set video1 as default for some apps.

How to reproduce, just open cheese , change to higher resolution and see crappy picture

Not a bug in cheese...

[Vish (vish)]

The same error is noticed in gstreamer as well hence the bug is tagged 'gstreamer-error'.

I get the same error messages from running skype at the command prompt with LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so or LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so , and the video that I transmit out has the same glitches as the attachment "Recorded Video". Please help!
