MCI_DGV_RECORD_PARMS structure (digitalv.h)
The MCI_DGV_RECORD_PARMS structure contains parameters for the MCI_RECORD command for digital-video devices.
Syntax
typedef struct {
DWORD_PTR dwCallback;
DWORD dwFrom;
DWORD dwTo;
POINT ptOffset;
POINT ptExtent;
RECT rc;
DWORD dwAudioStream;
DWORD dwVideoStream;
} MCI_DGV_RECORD_PARMS;
Members
dwCallback
The low-order word specifies a window handle used for the MCI_NOTIFY flag.
dwFrom
Position to record from.
dwTo
Position to record to.
ptOffset
ptExtent
rc
The region of the frame buffer used as the source for the pixels compressed and saved. RECT structures are handled differently in MCI than in other parts of Windows; in MCI, rc.right contains the width of the rectangle and rc.bottom contains its height.
dwAudioStream

When assigning data to the members of this structure, set the corresponding flags in the fdwCommand parameter of the mciSendCommand function to validate the members.
