Gstreamer : pipeline have not created

[meghnakapoor1234]

I am using Jetson Xavier NX and legion usb camera. I am running a simple code but I am getting an error stating gstreamer is missing some plugins and hence pipeline is not created. I have compiled OpenCV and gst from scratch. Can someone please make me understand why I am getting this warning? I am attaching screenshot of error for reference

Hi,
By default the gstreamer version is 1.14.5. The version in your log is 1.16.2. Not sure if the camera can work with default version. If possible, we would suggest try the default one.

And you can clean the cache and try again:

$ rm .cache/gstreamer-1.0/registry.aarch64.bin

@DaneLLL I am trying with default one still getting same warnings.

Hi,
Please follow the steps in Jetson Nano FAQ
Q: I have a USB camera. How can I launch it on Jetson Nano?

And check if you can run the camera in gst-launch-1.0 command first.

@DaneLLL Hey, vv4l2camerasrc is giving error of invalid token and after removing brackets it’s giving erroneous pipeline. Please see the screenshot

Hi,
Could you try v4l2src? The nvv4l2camerasrc plugin only supports UYVY format by default. Does not work for all USB cameras. Please confirm format of the USB camera is supported in v4l2src and give it a try.
