Issue with nvjpegdec in GStreamer pipeline

I’m encountering an error with the nvjpegdec element in my GStreamer pipeline.
Pipeline -
`‘v4l2src’ ‘device=/dev/video0’ ‘do-timestamp=true’ ‘!’ ‘identity’ ‘drop-buffer-flags=corrupted’ ‘!’ '‘watchdog’ ‘timeout=300000’ ‘!’ ‘image/jpeg,width=1920,height=1080’ ‘!’ ‘nvjpegdec’ ‘!’ ‘fakesink’

The error messages I’m seeing in the logs are:

I’ve tried adjusting the pipeline configuration, but I’m still unable to resolve this issue. As I’m relatively new to GStreamer, I would greatly appreciate any insights or suggestions on how to address this problem.

Gstreamer Version - 1.24.0

Thank you in advance for your help!

Hi, could you try adding a jpegparse before the nvjpegdec element?
Also please share the output of v4l2-ctl -d /dev/video0 --list-formats-ext (this program comes from v4l-utils package)
