How to check if the Jetson is using the Nvidia encoder correctly?

Hello,
I am currently using the ZED_Media_Server to create a virtual camera from my two ZED X One and I was wondering if there are any ways to know if the software is correctly using the GPU. Because I couldn’t get 60 fps with both Zed_x_one open at 1920x1080 60 fps and the CPU usage is very high. I am using a Jetson Xavier NX with 2 ZED X One and a duo capture card.
Thank you for your response.

Hi @LucasMarchnd
What version of the ZED SDK and ZED X Driver are you using?

If the ZED Media Server works, than it’s correctly using the GPU; otherwise, you should not get any kind of stream.

In any case, you could consider using jtop to monitor the CPU, GPU, and encoder/decoder usage:

Hi,
Thank you for your response,
I’m currently using ZED SDK 4.1.4 (this is the only SDK that is working for my installation) and for the ZED X Drivers I’m using Jetpack 5.1.2 (L4T 35.4.1).

Also, is there a way to see/set the bitrate of the stream?

Why do you affirm this? You can use the latest stable v4.2.5 with Xavier NX or the ZED SDK v5.0.2 GA that we released yesterday.

So I followed this and when I open zed media server I have this issue :

[ZEDMediaServer] Version  0.1.9

I get this error with each SDK I tried except the ZED SDK 4.1.4

@LucasMarchnd can you please share the log of the latest ZED Media Serve v5.0.2 GA?
We fixed many ZED Media Server issues with the latest ZED SDK release
