Parameter |
Description |
|
pCapture |
Pointer to an IltmfCapture 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 MediaFoundation documentation. |
Comments
IltmfCapture::CaptureDIB and IltmfCapture::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 IltmfCapture::get_CaptureStillDelay.
