Fix the selection of the video viewfinder resolution depending
on the features provided by the camera. If the viewfinder is responsible

and the video output must match. Otherwise only the ratio must match
and we can use a lower resolution for the viewfinder to improve
the performance of the NV12->RGB frame conversion.
