gstshark-plot: error: plot_interlatency: A(I,J,...) = X: dimensions mismatch

[chehefen]

I ran into this error when I try to plot the interlatency of a gstreamer pipeline that ran for a bit more than one minute: pi@raspberrypi:~/workspace/gst-shark/scripts/graphics$ ./gstshark-plot gstshark_2018-02-14_06:05:38/ Loading proctime events... Loading interlatency events... Loading scheduling events... Loading cpuusage events... Loading framerate events... octave: X11 DISPLAY environment variable not set octave: disabling GUI features Processing proctime... Processing interlatency... error: plot_interlatency: A(I,J,...) = X: dimensions mismatch error: called from plot_interlatency at line 89 column 60 ./gstshark-plot.m at line 35 column 13

Any pointers on how can I fix this? Thanks

I have the same problem, also with other event types (framerate and proctime [or should i write proc_time?]). This bug makes the plotting currently unusable. One has to look in the Octave code...

I have also the same issue. @chehefen, Did you solve this issue?

Debugging

$ ./gstshark-plot ./gstshark_2018-11-20_19:47:46/ -s pdf -p -l extern

Analysis

It seems that value_mat gets the mismatched dimension values when creating matrix to store the data.

@mleivaf, @michaelgruner PTAL, Could you give us a hint to fix this issue?

[rrcarlosrodriguez]

Hi all,

Sorry for the delay in our answers. We updated Gst-Shark (v0.5.5) some days ago, could you please give it a try an see if the issue still appears? Changes were mainly focused on the plotting functionality
