Consider V4L2 drivers will usually be used for streaming, so using 2 OUTPUT and 2 CAPTURE buffer isn't special, so perhaps find something that will be possible to allocate ? I bet you can't even have more then 4G of ram on that device, so even if theoretically you could program the HW for 16383x65535, it is physically impossible to allocate a second buffer of that size
