UVC USB3.0 Camera Not Initializing

jefson · June 25, 2019, 9:21pm

Hi, i am trying to use 2 USB3.0 Cameras with sony IMX291 sensors to test the AI and stereo camera functions, but I’m running into problems getting the cameras initialized. I started with guvcview to see the video, but it cannot find the cameras. I got the tensor demo program to run, it sees the cameras, but I want to use the v42l-ctl to set exposure and frame rates.

this is what I get from dmesg when I plug one in:

[ 3217.839409] usb 2-1.3: new SuperSpeed USB device number 12 using tegra-xusb

here is v4l2-ctl --list-devices

~$ v4l2-ctl --list-devices
3.0 USB Camera (usb-70090000.xusb-1.1):
/dev/video1

3.0 USB Camera (usb-70090000.xusb-1.4):
/dev/video0

QUESTION: Is guvcview the best route for camera controls? if yes- then can this be fixed and how; if no- please help point me to the best camera control.

Thank you in advance

Hi,
Please share below information of your USB cameras:

$ v4l2-ctl --list-formats-ext -d /dev/video0

Hi,
Please try gstreamer pipeline:

$ gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=YUY2,framerate=60/1,width=1280,hight=720 ! nvvidconv ! 'video/x-raw(memory:NVMM),format=NV12' ! nvoverlaysink

I get a similar error trying to use guvcview on the Xavier. I found that killing the ibus daemon before launching guvcview fixed it for me:

sudo killall ibus-daemon
