I agree with piman@ here. This seems very dangerous to me.

There is a VaSurfaceAttribMaxWidth & VaSurfaceAttribMaxHeight which are
unfortunately not implemented in the intel driver but I will try and garner some
support for implementing.

+  else
+    resolution.max.SetSize(1920, 1088);
+  return resolution;
