I am currently using Jetson TX2 and LI IMX185 camera to my project and the following are the available sensor modes that the camera can provide. When the sensor mode is set to resolution at 1080p, everything seems to work fine in terms of frame rate (ie. FR=30.000000, Frame rate is around 30 and when FR=60.000000, the frame rate is around 60). However, when I set the Sensor mode to the one at 720p, trying to achieve the frame rate of 120 fps, it seems that it has been limited to around 58 to 60 fps (same results as when using 1080p with 60 fps but it can be seen that the resolution has been updated from inspection) with nothing else running. Is there a way to check what is limiting my frame rate at 60 fps?
I am using R28.2.
