The DDVIDEOPORTCONNECT structure describes a video port connection. This structure is used with the IDDVideoPortContainer::GetVideoPortConnectInfo method.
typedef struct _DDVIDEOPORTCONNECT{
DWORD dwSize; // Size of the DDVIDEOPORTCONNECT structure
DWORD dwPortWidth; // Width of the video port
GUID guidTypeID; // Description of video port connection
DWORD dwFlags; // Connection flags
DWORD dwReserved1; // Reserved, set to zero.
} DDVIDEOPORTCONNECT,*LPDDVIDEOPORTCONNECT;
DDVPTYPE_E_HREFH_VREFH | External syncs where HREF is active high and VREF is active high. |
DDVPTYPE_E_HREFH_VREFL | External syncs where HREF is active high and VREF is active low. |
DDVPTYPE_E_HREFL_VREFH | External syncs where HREF is active low and VREF is active high. |
DDVPTYPE_E_HREFL_VREFL | External syncs where HREF is active low and VREF is active low. |
DDVPTYPE_CCIR656 | Sync information is embedded in the data stream according to the CCIR656 spec. |
DDVPTYPE_BROOKTREE | Sync information is embedded in the data stream using the Brooktree definition. |
DDVPTYPE_PHILIPS | Sync information is embedded in the data stream using the Philips definition. |
DDVPCONNECT_DOUBLECLOCK | Indicates that the video port either supports double-clocking data or should double-clock data. This flag is only valid with an external sync. |
DDVPCONNECT_VACT | Indicates that the video port either supports using an external VACT signal or should use the external VACT signal. This flag is only valid with an external sync. |
DDVPCONNECT_INVERTPOLARITY | Indicates that the video port is capable of inverting the field polarities or is to invert field polarities. When a video port inverts field polarities, it treats even fields as odd fields and vice versa. |
DDVPCONNECT_DISCARDSVREFDATA | The video port discards any data written during the VREF period, causing it to not be written to the frame buffer. This flag is read-only. |
DDVPCONNECT_HALFLINE | The video port will write half lines into the frame buffer, sometimes causing the data to be displayed incorrectly. This flag is read-only. |
DDVPCONNECT_INTERLACED | Indicates that the signal is interlaced. This flag is only used by the client when creating a video port object. |
DDVPCONNECT_SHAREEVEN | The physical video port is shareable, and that this video port object will use the even fields. This flag is only used by the client when creating the video port object. |
DDVPCONNECT_SHAREODD | The physical video port is shareable, and that this video port object will use the odd fields. This flag is only used by the client when creating the video port object. |
This structure is used independently and as a member of the DDVIDEOPORTDESC structure.
