Not development related, but I'm hoping y'all can help...
I've got a PWC camera (Logitech QuickCam 4000 Pro) that works fine
normally.
One of our new projects requires a run of 120 feet or so from the
computer to the camera. I'm using an IOGear extender to do this over
CAT5 cable. This works fine wiht a 90' cable, but that is just a tad
too short to use in this instance. So we got a different IOGear
extender that claims 197 feet...
At first, the system (Debian) would load the module and detect the
camera, and create the /dev/video0 dev entry. However, if I tried to
take a pic, it wouldn't be able to connect. Contacted IOGear, they
recommended a powered USB hub between the computer and the adapter. So
I've got that. Now when I try and take a pic, I get an ioctl error
from streamer (the app I'm using to take the pic):
streamer -c /dev/video0 -s 640x480 -o foo.jpeg
files / video: JPEG (JFIF) / audio: none
ioctl:
VIDIOC_S_FMT(type=VIDEO_CAPTURE;fmt.pix.width=640;fmt.pix.height=480;fmt.pix.pixelformat=0x32315559
[YU12];fmt.pix.field=ANY;fmt.pix.bytesperline=0;fmt.pix.sizeimage=460800;fmt.pix.colorspace=unknown;fmt.pix.priv=0):
Invalid or incomplete multibyte or wide character
Oops: ratio size renegotiation failed
Checking the output of dmesg, I see that the camera is connecting and
disconnecting and being re-recognized, and I also have:
usb 1-2.3: configuration #1 chosen from 1 choice
pwc: Logitech QuickCam 4000 Pro USB webcam detected.
pwc: Registered as /dev/video0.
pwc: Failed to set video mode fps; return code = -84
In my dmesg output.
Any ideas?
Thanks!
