/* Note some of the sizeimage values for the ov511 / ov518 may seem
larger then necessary, however they need to be this big as the ov511 /
ov518 always fills the entire isoc frame, using 0 padding bytes when
it doesn't have any data. So with low framerates the amount of data
transfered can become quite large (libv4l will remove all the 0 padding
in userspace). */
