Description |
pCapture |
Pointer to an IltmmCapture interface. |
Delay |
Value that represents the time delay, in milliseconds. The default value is zero. |
Returns
S_OK |
The function was successful. |
<> S_OK |
An error occurred. Refer to the Error Codes or the HRESULT error codes in the DirectShow documentation. |
Comments
This property affects the amount of time it takes to capture a still image using the IltmmCapture::CaptureDIB and IltmmCapture::CapturePicture.
The meaning of the property is affected by the StillTap property:
When capturing from the still pin, the capture happens when the user presses the hardware button for capturing the still image. If there is not a hardware button or the user doesn't press it, the capture occurs after the timeout specified by this function.
When not capturing from the still pin, the capture occurs after the amount of time specified by this function. IltmmCapture::CaptureDIB and IltmmCapture::CapturePicture wait the amount of time set by this function before grabbing a sample. Using the time delay is beneficial when using a capture device that creates poor quality frames when it first starts capturing.
To get the current time delay, call IltmmCapture::get_CaptureStillDelay.
