Using external trigger signal for GMSL camera in Drive PX2 unit

Hi,

When I run the dw sample (lane detection and drivenet) with the sf3324 camera, I want to run it by lowering the frame rate of the camera to 20 Hz. (When I ran sample_camera_gmsl, I confirmed that my camera’s fps is 30.)
And unfortunately there is no dwx_recording_library.html in my directory.

Referencing Setting camera frame rate, I could check the properties of the camera, but I couldn’t find any function to set the framerate.

Is there a way to run dw sample after setting the frame rate of sf3324 to 20hz?
