Input Buffer Order Rules

  • Article

This section applies only to Windows Server 2003 with SP1 and later, and Windows XP with SP2 and later.

The order of the surfaces within the lpBufferInfo array conforms to the following rules:

  • The first surface in the array is the destination surface. The driver only writes to the destination surface.

  • The next sequence of surfaces in the array is the group of any previous destination surfaces, in reverse temporal order, that the deinterlacing device requested for its deinterlace algorithm.

  • The next sequence of surfaces in the array is the collection of input interlaced or progressive surfaces that the device requires in order to perform its deinterlace operation.

  • The next sequence of surfaces in the array is the collection of video substream surfaces, which are in Z order.
