Camera board • Re: Low FPS video capture through libcamerify

libcamerify doesn't expose all the possible controls and options of libcamera.

The default libcamera viewfinder role allows for a somewhat variable frame rate, generally with a minimum of 15fps, to allow auto exposure to go up to 66ms exposures. libcamerify appears not to override that, so if you haven't got good lighting then I suspect that AE has done just that, and you get around 15fps.
I'm testing in a pretty bright environment and the frames look properly exposed, any way I can adjust that to get at least 30?

Edit:
I just tried the v4l2-ctl stream test while pointing the flashlight at the camera and only then I get 30fps, it seems then the exposure and ISO settings aren't right for video recording, any way I can change those?

Edit2:
I still get low framerate (16.40fps) using the C program while pointing the flash.
