I am writing Python code for processing several of RTSP streams on an 8G Jetson Orin NX system, using opencv. I’ve been told that it should be able to handle up to 12 4K streams at 15 fps provided that I used GStreamer for decoding them. However, I can’t get it to go past 8 1280x960 streans at 15fps…

Hi, Please apply the patches and rebuild kernel: Jetson AGX Orin FAQ And try again.

Hi, For information, do you run decoding tasks in single process with multiple decoding threads? Or multiple processes?

Hi DaneLLL, each decoding task is run as a separate process. Thanks for the quick reply :)

Hi DaneLLL I started back again with a blank installation of my dev kit with JetPack 6.2 (L4T 36.4.3, Kernel Version 5.15.148-tegra). For some reason I am not able to install OpenCV with GStreamer support now. Is there any official Nvidia tutorial for that? The previous time I installed it, I foll…

Hi DaneLLL, will using multiple decoding threads solve the issue instead of doing it per-process? And also, when will Jetpack 6.3 containing the kernel patch be released? Would rather wait for the official upgrade rather than patching ourselves which I am not sure is suitable for production. Thanks…

Hi, The issue does not occur if you run multiple decoding threads in single process. Would be great if you can try this. And the patches are not included to Jetpack versions in r36.4.x. Will be in future r36.5.x.

Hi DaneLL, Thank you, I completely misunderstood. I will try to apply patches manually (If I understood correctly). To be frank I am completely new to working with Jetson devices and I’m a bit lost. Could you point me, please, to some tutorial or post about how to apply said patches? Thank you ver…
