The VPFlags property defines flags indicating what video port options are to be utilized when transferring data to a surface.
The described effect applies when the flag is set.

DDVP_AUTOFLIP
Autoflip to the next destination overlay surface in the flip chain as each VREF occurs.
Flips will occur every VREF unless the fields are being interleaved in memory, in which case flips will occur every second VREF.

DDVP_CONVERT
Video data is to be color converted before it is written to a surface by using the pixel format information referenced by TDDVideoPortInfo::OutputFormat.

DDVP_CROP
Video data is to be cropped using the rectangle referenced by TDDVideoPortInfo::Crop, before writing it to a surface

DDVP_IGNOREVBIXCROP
X axis cropping coordinates are to be ignored when cropping oversampled VBI data.

DDVP_INTERLEAVE
Interlaced fields are to be interleaved in memory.

DDVP_MIRRORLEFTRIGHT
Image data is to be irrorred from left to right when writing to the frame buffer.

DDVP_MIRRORUPDOWN
Image data is to be mirrorred from top to bottom when writing it to the frame buffer.

DDVP_OVERRIDEBOBWEAVE
Override any automatic display methods chosen by the driver and use only the display method set by the caller when they created the overlay surface.

DDVP_PRESCALE
Pre-scale or zoom the video data based on the values in TDDVideoPortInfo::PrescaleHeight and TDDVideoPortInfo::PrescaleWidth.

DDVP_SKIPEVENFIELDS
Ignore the even field of the video frames.

DDVP_SKIPODDFIELDS
Ignore the odd field of the video frames.

DDVP_SYNCMASTER
Lock the graphics refresh rate to the video port by using the video port VREF as the graphics VREF.

DDVP_VBICONVERT
Convert VBI data contained in the video stream using the pixel format information contained in TDDVideoPortInfo::VBIOutputFormat.

DDVP_VBINOINTERLEAVE
Disable interleaving in memory for data contained within the VBI.

DDVP_VBINOSCALE
Do not perform any scaling on VBI data contained within the video stream.
