No element "nvv4l2decoder"

[park.kyungmin]

I’m currently trying to stream ThetaX using gstreamer. However, I’m currently having an issue where I can’t use the nvidia plugin unless I use su. For example,
“sudo gst-launch-1.0 thetauvcsrc mode=4K ! queue ! h264parse ! nvv4l2decoder ! nvvidconv ! queue ! nvv4l2h264enc ! h264parse ! video/x-h264,stream-format=byte-stream ! queue ! fdsink fd=1”
runs without any problems, but

“gst-launch-1.0 thetauvcsrc mode=4K ! queue ! h264parse ! nvv4l2decoder ! nvvidconv ! queue ! nvv4l2h264enc ! h264parse ! video/x-h264,stream-format=byte-stream ! queue ! fdsink fd=1”
the following error occurs. [no element nvv4l2decoder]

I would appreciate it if you could tell me why this problem occurs and how to fix it.

Hi,
Please clean gstreamer cache and check if it helps:

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

Orin Nano does not have hardware encoder, so it is a bit strange you can use nvv4l2h264enc plugin.

Sorry, I made a mistake with the product.
The board I’m using now is “orin nx”. I’ve corrected the product tag.

I think deleting the log solved the problem.

Thank you.
