Have you considered adapting your maximum width/height to something reasonable ?
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 (or any size).

Have you considered adapting your maximum width/height to something reasonable ?
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 (or any size).
