Value Meaning
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

If the method succeeds, the caller must free the returned picture by calling the interface Release method.

The frame is captured from the position indicated 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 does not press it, the capture occurs after the timeout specified by the TimeOut parameter.

When not capturing from the still pin, the capture occurs after the amount of time specified by the TimeOut parameter.

If TimeOut is INFINITE, the function's time-out interval never elapses.
