capture
The capture command copies the contents of the frame buffer and stores it in the
specified file. Digital-video devices recognize this command.
wsprintf(lpstrCommand, "capture %s %s %s", lpszDeviceID, lpszCapture,
lpszFlags);
Parameters
lpszDeviceID
Identifier of an MCI device. This identifier or alias is assigned when the
device is opened.
lpszCapture
One or more of the following flags:
as pathname
| Specifies the destination path and filename for the captured image. This flag
is required.
| at rectangle
| Specifies the rectangular region within the frame buffer that the device crops
and saves to disk. If omitted, the cropped region defaults to the rectangle
specified or defaulted on a previous put "source" command for this device instance.
|
lpszFlags
Can be "wait", "notify", "test", or a combination of these. For more
information about these flags, see The Wait, Notify, and Test Flags.
Return Values
Returns zero if successful or an error otherwise.
Remarks
This command might fail if the device is currently playing motion video or
executing some other resource-intensive operation. If the frame buffer is being
updated in real time, the updating momentarily pauses so that a complete image is
captured. If the device pauses the updating, there might be a visual or
audible effect. If the file format, compression algorithm, and quality levels have
not been set, their defaults are used.
