Sets the position, in the stream, where the still images are tapped from.
|C||HRESULT IltmmCapture_put_StillTap(pCapture, newVal)|
Pointer to an IltmmCapture interface.
Value that is one of the ltmmCapture_StillTap enumeration constants.
|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.|
This property indicates where the still image should be captured from. Some capture devices have a still pin, usually it is present when they have a hardware button that can also serve as a trigger for a capture.
When the StillTap property is set to ltmmCapture_StillTap (indicating the still image should be captured from the still pin), the capture occurs when the hardware button is pressed. If there isn't a button or the user does not press the button, the capture occurs after the timeout specified.
When the StillTap property is not ltmmCapture_StillTap (indicating the still image should be grabbed from the capture pin or from the processors), the capture occurs after the timeout specified.
In both cases, the timeout is passed as an argument (IltmmCapture::GetStillDIB, IltmmCapture::GetStillPicture, IltmmCapture::SaveStillDIB, IltmmCapture::SaveStillBitmap) or through the IltmmCapture::put_CaptureStillDelay property (IltmmCapture::CaptureHDib and IltmmCapture::CapturePicture).
