Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU) Jetson AGX Orin
• DeepStream Version 6.1
• JetPack Version (valid for Jetson only) 4.x
• TensorRT Version 8.4
• Issue Type( questions, new requirements, bugs) questions

Hi, I have a gstreamer pipeline which stops at a moment after every 15-20 frames.
I investigated what is the cause but i have no idea on this since the issue occurs even i removed heavy elements (like nvinfer, nvdsnalaytics, nvtracker).

i also checked resource usage on AGX Orin. Its GPU and CPU usage was quite low while the pipeline is working.

So i think my issue is related to buffering in gstreamer.
I want to know how to optimize buffering in the pipeline.

Thanks.

which deepstream sample is your code based on? could you provide simplified code to reproduce this issue? maybe some elements is waiting because buffers are taken by other elements.

#4

Ok.
My app consists of 600 lines, so i will recheck by myself at first.

#5

Any further update? Is this still an issue to support? Thanks

#6

I’m currently investigating by myself. I will report by the end of today whether further support is needed.

#7

Anyway thanks a lot for caring my problem.

Finally, i was able to get the clue to fix the issue.
In my situation, the issue was related to disordered timestamps of rtmp stream.
It was not gstremer’s fault, but my network cam’s problem.
