hi list
finally after some nice kernelcompiling my usbwebcam is working. at least in camstream i recieve the images i want.
but if i use the cam with pdp the xv-window is splitted into two parts a green and a dark green one, no images are visible. but there are no errors on the printout.
i don't work on pdp, but i think i know what the problem is. you are most likely seeing an improper display of yuv color-space in an rgb display. pdp might have a color-space conversion object that would convert yuv to rgb and vice versa. a potential source of the problem you are seeing is the webcam reporting the wrong color space or pdp not detecting the right one to use. i don't really know a whole lot about v4l, but i seem to recall it supporting several color-spaces for capture devices.

what could this be? thx marc
