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
