LI-IMX390-GMSL2 camera latency

ShaneCCC thanks for your reply.

Unfortunately this camera can only output 30fps.
Is there no way to get lower latency?

I saw this post:

Low-latency camera for Jetson TX2

So currently all we know is: IMX274 by Leopard Imaging is good (40+ ms), thanks to RidgeRun measurements: NVIDIA Jetson TX1 TX2 Glass to Glass latency | Jetson TX1 TX2 Capture | RidgeRun But the sensor is not cheap enough for mass production ($250). Raspberry Pi Camera 2.1 (IMX219) is bad (130 ms): Jetson J20 imx219 Glass to Glass Latency | RidgeRun Developer ov5693 is average (70 ms): https://devtalk.nvidia.com/default/topic/1026587/?comment=5245511 RidgeRun can develop a driver…

that mentioned they can reach as low as 40ms.
Do I need to build special drivers for that?

I also saw this post:

nvcamerasrc queue-size property limitation

Hi DaneLLL, Thanks for your advice. I finally got the latency of about 80msec. The following summarizes what I have done: Download latest Tegra_Multimedia_API - https://developer.nvidia.com/embedded/dlc/l4t-multimedia-api-32-1-JAX-TX2 Use Jetpack to install latest NVIDIA CUDA, OpenCV4tegra, cuDNN, NVIDA TensorRT according to https://docs.nvidia.com/jetson/l4t-multimedia/mmapi_build.html Compile libargus according to https://developer.ridgerun.com/wiki/index.php?title=Xavier/Video_Capture_…

that mentions the queue size may impact the latency.

Thanks,
Amir
