The camera modes supported by the kernel's camera driver are key here. You can force any of the available camera modes to be chosen, and you can request any output resolution you like (which will be obtained by resizing the image obtained from the sensor), but the maximum framerate and FoV are still determined by that camera mode.Hi,
I am using 4 cameras on my board and am already asking it to do alot for its form factor. I want to use the full FOV of the imx708 but of course at the most frames possible. The best resolution seems to be 2304x1296 but that only operates at 56fps. Is there a way to render at a lower resolution with libcam-hello but still have the 2304x1296 resolution and squeeze more fps out of it? I would certainly use 1536x864 if its FOV wasn't cropped to all hell...
For the camera module 3, the 2304x1296 mode gives you the full FoV, and a maximum of 56fps. The 1536x864 mode will go faster, but with a limited FoV (it is "cropped"). There's nothing you can do about this without changing how the kernel drives the camera (usually very difficult without support from the camera manufacturer), or by choosing a different camera.
For completeness, the easiest way to discover the available modes, with their framerates and FoV, is to use "rpicam-hello --list-cameras".
