The following line of application code

Produces the following debug statements

0:00:00.076605881 17615   0x55a809e600 INFO     GST_ELEMENT_FACTORY gstelementfactory.c:359:gst_element_factory_create: creating element "nvjpegdec" named "jpeg-decoder"

This seems to be identical to L4T 28.1 : Gstreamer 1.0 and BusError on nvjpegdec plugin

which was closed several years ago without a resolution

I’ve confirmed the below works…

gst-launch-1.0 filesrc location="sample_720p.jpg" ! nvjpegdec ! imagefreeze ! xvimagesink -e

Hi,
The nvjpegdec plugin is not supported in DeepStream SDK. Please try

... ! jpegparse ! nvv4l2decoder mjpeg=1 ! ...

Thanks for the quick response @DaneLLL … the above works well for my needs.
