While testing the camera, a new symptom occurred, so I am writing to find a solution.
The configuration currently being worked on is
Xavier NX+ Custom Carrier + MIPI 2Lane Camera 4Port,
I am using Jetpack5.1.1 and deepstream-6.2 versions.
There is no problem if MIPI cameras are operated one at a time, but problems occur if two or more MIPI cameras are operated simultaneously.

After the message shown in the log above appears, frame drops occur little by little, and then the video stops.
One thing I’m curious about here is that the symptoms change when you change the power mode.
7: In MODE 10W DESKTOP mode, it operates normally without frame drops (highest CPU clock: 4 core, 1.9 GHz)
In addition, when the number of cores increases or the clock speed decreases, video stuttering increases noticeably.
Can you tell me what the reason is??
In theory, I think that this symptom may occur because the faster the CPU, the faster the processing speed, of course…
Does displaying on the screen using the deepstream app use a lot of CPU resources?
