TROUBLESHOOTING

  • (darknet:65): GStreamer-CRITICAL **: 15:28:37.223: gst_element_get_state: assertion 'GST_IS_ELEMENT (element)' failed
VIDEOIO ERROR: V4L: device v4l2src ! video/x-raw, framerate=30/1, width=640, height=360 ! videoconvert ! appsink: Unable to query number of channels

    Means USB Cam wasn't found, make sure it is connected and restart your jetson Another reason could be that the usbcamera is not in the standard path. Try to add e.g. device=/dev/video1 after v4l2src.

  • Installing opendatacam docker image
Stop any running docker container...
"docker stop" requires at least 1 argument.

    Happens if the opendatacam is installed after a clean flash. Run $ sudo docker run hello-world so that there is a container to stop.

  • If it happens, that the docker service is not active on startup (which means the container is not starting automatically). Run $ sudo systemctl enable docker set the docker service active on startup

  • docker: Error response from daemon: OCI runtime create failed: container_linux.go:345

    Try restarting the docker service: sudo service docker restart , also try to restart your machine.

  • Error generated. /dvs/git/dirty/git-master_linux/multimedia/nvgstreamer/gst-nvarguscamera/gstnvarguscamerasrc.cpp, execute:521 No cameras available

    Rasberry Pi Cam isn't working, try rebooting your device / plug it again.
