[PD] gridflow with web-#camera

[olsen]

Salute
tried to get a videoimage from a webcam into gridflow - due to the 
output the camera is recognized (see below) but bangin the [metro 
33.3667] gf is complaining about:

[gf] ioctl VIDIOCMCAPTURE: Invalid argument
error: ArgumentError: ioctl error
format/videodev.c.fcs:358:in `void FormatVideoDev::frame_ask(int, Ruby*)'
[#in]

anyone using #camera with a webcam? does it work only with tv-card?
thanks
olsen
