Hi, i am try to use opencv’s imshow to show some auxiliary information within a probe but nothing happened. I can verify that printing out the same set of info to the linux terminal working. I added waitkey(1) but its still not working. its just a black screen. How can i make it work ?

Are you running on docker? Did you mount the .X11-unix and DISPLAY variables?
Btw adding an imshow in a probe might result in a log of frame drop.
Hi marmikshah, i am running in docker. I am able to see the out of my pipeline via NV_OSD just that the imshow call seems to be do nothing. I understand the imshow in a probe will have performance impact. Its for testing purpose for now. I also did try to call imshow on a separate thread to show the auxiliary information but could not make it to work as well.
I see. Do you have any code to reproduce the problem?
There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks
Sorry for the late reply, Is this still an DeepStream issue to support? Thanks
