I am trying to use gstreamer and ROS to capture an external USB video camera.
I followed the Accelerated Gstreamer guide and have all the packages installed however when I am trying to launch the following I got an error:

I assume nvv4l2h264enc should be supported on Xavier AGX? or which encoder should I use for H264?
