Unable to view the plots using gst-shark

[kandoiNikhil]

I capture the trace on a gstreamer pipeline running on a nvidia xavier AGX. I then take the output directory and copy it to my mac and run the gstshark-plot script to get some charts but it isn't working for me. Any quick tips on how I can get past this issue ??

warning: using the gnuplot graphics toolkit is discouraged

The gnuplot graphics toolkit is not actively maintained and has a number
of limitations that are unlikely to be fixed.  Communication with gnuplot
uses a one-directional pipe and limited information is passed back to the
Octave interpreter so most changes made interactively in the plot window
will not be reflected in the graphics properties managed by Octave.  For
example, if the plot window is closed with a mouse click, Octave will not
be notified and will not update its internal list of open figure windows.
The qt toolkit is recommended instead.

Hi, are there any actual contents in the directory? Can you open the metadata file and share the contents? What files can you see in the directory?

There is a datastream file in there as well This is the entire directory : https://www.dropbox.com/sh/lip29og3ujq7wl3/AACEhHAVnjtKkSdU3ApCj01_a?dl=0

[abrowne2]

Also having this issue as well; I have datastream & metadata that looks similar to the above. Having issues getting it to generate anything.

Thanks for sharing the trace. Let me get into it and get back to you. Can you also share the pipeline and tracers you are using?
