Does not quit properly if I use jetson.utils.glDisplay()

[AK51]

Hi,

I follow this link for the full screen display and it works.

How to set full screen display?

Hi, I am running dusty-nv inference and it runs great. How can I make the display to cover the full screen? I was looking at this forum, do I just need to update the github and display.SetMaximized(True) or display.SetFullscreen(True) in python code? Kind of lost, sorry. I have git clone the newest github and add the line display.SetMaximized(True) or display.SetFullscreen(True) error of no attribute though… still debugging Do I need to install/update the jetson-utils? I follow gi…

However, when I click “escape” the program does not quit properly and I need to kill the process in task manager.
Here is the skeleton of my program about the output. How to make the program quit properly? Thx

output = jetson.utils.glDisplay()
output.SetFullscreen(True)
while output.Isopen():

#	output.Render(img)
	output.RenderOnce(img,img.width, img.height,x=0,y=0)

	# exit on input/output EOS
#	if not input.IsStreaming() or not output.IsStreaming():
#		break

@AK51

#	if not input.IsStreaming() or not output.IsStreaming():
#		break

Hi @AK51, can you try this?

     if output.IsClosed():
          break

Dear Dusty,

I have tried many times and it fails one time still… But it is better than before. Thx

I put
jetson.utils.cudaDeviceSynronize() before/after detectnet as well as posenet.

When I use jetson.utils.glDisplay(), the nubuf_utils keeps showing but the software runs.
I did not do any cuda memory clone nor copy,
And I comment out all jetson.utils.cudaDrawLine and jetson.utils.cudaDrawRect…

When I click escape, the terminal and the screen freeze…

Dear Dusty,

It seems working now. :> Thx Dusty
I put
if output.IsClosed():
break
right before
output.RenderOnce(…)
It can eliminate the time gap.

Cheers

OK great, glad you found a way to make it work. Unfortunately I can’t eliminate the messages from nvbuf_utils as they come from a different library.
