gst-inspect is not work properly in DS4.0

ahyuo79 · August 2, 2019, 2:02am

I have a question about Gstreamer ,
I used gst-inspect command in DS3.0 because I wanted to check pad and element information
but It does not work in DS4.0 properly so I can’t see any information about deepstream plugin javascript:void(0);

I checked this command below on Xavier after I installed Jetpack 4.2.1 with DS4.0 by using sdkmanager
Could I install something more ?

/opt/nvidia/deepstream/deepstream-4.0/lib/gst-plugins$  gst-inspect-1.0 nvstreammux

Hi,
Please check if cleaning cache helps:

If the application encounters errors and cannot create Gst elements, remove the GStreamer cache, then try again. To remove the GStreamer cache, enter this command:
$ rm ${HOME}/.cache/gstreamer-1.0/registry.aarch64.bin

ahyuo79 · August 5, 2019, 2:36am

Hi,
Thanks for your help

I found that why doesn’t work it properly," gst-inspect-1.0 nvstreammux"
because I used to send a command by SSH
it was working if used terminal

but I remember that last version DS3.0 on Xavier was wokring this command properly like gst-inspect-1.0 on SSH

Hi,
Thank you for your fast response

I checked your way to use this command was working on SSH properly a few mins ago
I think the connection with X protocol option to Xavier was the problem

ssh -X nvidia@192.168.55.1  // same problem 
ssh  nvidia@192.168.55.1  // working properly

Thank you :)

Hi,
With ‘-X’, please configure export DISPLAY=:1(or 0)

Hi ahyuo79,

Have you tried with our suggestions? Is it working?

Thanks

ahyuo79 · August 13, 2019, 7:31am

Hi kayccc,

now it’s clear and working

Thank you for your help,
