Hi All,
I have a Logitech Pro 9000 Webcam, which i want to enable in my wayland image running in Renesas Board, so that i can further use this webcam for my opencv applications.
Things i tried:
-
When i do lsusb - it shows camera name.
Is that means drivers are installed? -
dmesg output:
uvcvideo: Found UVC 1.00 device <unnamed> (046d:0809) input: UVC Camera (046d:0809) as /devices/platform/pci-rcar-gen2.1/pci0002:01/0002:01:02.0/usb4/4-1/4-1.2/4-1.2:1.0/input/input5
So i think all drivers are installed.
- v4l2-ctl --list-devices:
Listed on which device node my webcam is configured i.e. /dev/video4.
when i do ls -al it shows its a capture device.
But when i try to open webcam using gstreamer i get this error and it hangs for an indefinite time:
gst-launch-1.0 -e v4l2src device=/dev/video4 io-mode=dmabuf ! video/x-raw, width=800, height=480, format=UYVY, framerate=30/1 ! waylandsink

I don’t know what is wrong. Please help.
