Hello,

Thanks for visiting the NVIDIA Developer forums! Your topic will be best served in the Jetson category.

I will move this post over for visibility.

Hi,

Please try to run the clocks.sh script to maximize the device performance and try it again.

Hi,

No, VPI is a vision processing library so not able to change the setting of the camera.
Please check if your request can be done with argus or GStreamer instead.

Thanks.
