AR0230 framerate control

Hi,

is it possible to control framerate of this camera?

v4l2-ctl --list-formats-ext lists 30 fps

ioctl: VIDIOC_ENUM_FMT
        Type: Video Capture

        [0]: 'UYVY' (UYVY 4:2:2)
                Size: Discrete 1920x1080
                        Interval: Discrete 0.033s (30.000 fps)
                Size: Discrete 1280x720
                        Interval: Discrete 0.033s (30.000 fps)
                Size: Discrete 640x480
                        Interval: Discrete 0.033s (30.000 fps)
                Size: Discrete 320x240
                        Interval: Discrete 0.033s (30.000 fps)

but when running arducamstill it outputs 45fps

./arducamstill -t 0 -e h264

No match to hardware version!
Device /dev/video0) opened.
Video format set: UYVY (59565955) 1920x1080
