Hi. I am currently setting up a camera on a jetson nano for an imaging system. I have the camera working and streaming video fine however I cannot get the fps to increase above 30 fps even though the supported modes state that I can get 60fps at 1280x720. I am using the c++ code from Jetson Hacks. I have tried lowering the image resolution to see if the jetson is maybe not able to stream the images fast enough. I am using a camera with an imx219 sensor. I have also tried using gstreamer in the terminal. There I can only stream at 21 fps. Any value higher than 21 spits out an error stating that the frame rate is set higher than the supported value. Any advice will be much appreciated. Thanks

Ok seems the driver supports framerate over 30. I always try to use v4l-ctl to verify if the frames are correctly being dequeue and that the capture subsystem was configured correctly.

I am using the latest Jetpack image (4.3) so I am assuming that I am using the drivers as well. I have not installed my own drivers. The output to the command is:

The gstreamer pipeline I am using is the same one as used in simple_camera.cpp. I have realised though that the reason I wasn’t getting higher than 30 fps is because the waitkey parameter was set to 30 and I did not change it. This means that the code was waiting for 30ms and thus limiting the frame rate. I changed this to 10 and now can get 60 perfectly fine. I am still not sure why the terminal commands don’t allow me to stream above 21 fps. I am still very new to cameras and gstreamer. Thanks for the help.

Are you using the IMX219 driver provided by default with latest Jetpack release? The issue probably is related with the default modes and framerates supported by this driver.

Sorry for the late reply. I tried to use the command you suggested however the width and height are not being changed. Below is the output to that command:

As you can see the capture subsystem is configured for the resolution 3264x2464 and therefore that is why you are only getting 21 FPS (which is expected because that is the framerate that resolution supports). For some reason the driver is not configuring the expected resolution.

Field of View (FOV) defines an observable area or the range of vision seen via an XR device such as HMD when the user is static within a given XR environment. The standard human FOV is approximately 200 degrees, but in the immersive experience it may vary.A higher FOV contributes to a more immersive feeling.
