Seems you have to provide correct configuration values what your camera/senor module supports

fmt.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
fmt.fmt.pix.pixelformat = V4L2_PIX_FMT_UYVY;
fmt.fmt.pix.field = V4L2_FIELD_NONE;

fmt.fmt.pix.width = *captureWidthByRef;
fmt.fmt.pix.height = *captureHeightByRef;

These are the parameters you pass in file for S_FMT
Check if the Height, width UYVY pix format is supported
Could you give more details of the camera you have and the driver?

is it a USB camera?
Which driver does this camera use?

Can u mention the source where u downloaded the driver source or share the driver?
The issue can be solved easily just by looking into the driver.
