We are testing a Stereolabs ZED Box Duo based on an NVIDIA Jetson Orin NX platform. On the device, cat /proc/device-tree/model reports NVIDIA Jetson Orin NX Engineering Reference Developer Kit, the system has about 15 GiB RAM visible to Linux, and nvpmodel -q confirms we tested in 25W mode (mode 3). The box is running NVIDIA L4T R36.4.7 / kernel 5.15.148-tegra, with package stereolabs-zedbox-duo 1.4.1-LI-MAX96712-ZEDBOX-L4T36.4.0, and ZED SDK 5.2.2. We are running two ZED X cameras over GMSL, both configured for HD1200 (1920x1200) at 60 FPS, recording to SVO2 with H.264 GPU encoding, with depth disabled, live preview disabled, and preview JPEG saving disabled. A grab-only benchmark can run essentially at the full 60 FPS on both cameras, but sustained dual-camera recording starts near 60 FPS and then drops to about 18–19 FPS per camera. We are trying to understand whether this sustained dual-recording behavior is expected on ZED Box Duo / Orin NX at this resolution and frame rate, or whether there is a configuration or platform issue we are missing.
Hi @imedplb344
Welcome to the StereoLabs community.
We recommend you enable the MAXN power mode and launch the jetson_clocks command to obtain the maximum performance.
This is expected with the power mode that you are using.
