Pointer to an IltmmPlay interface. |
|
TimeOut |
Value containing the maximum time, in milliseconds, to wait for the image. |
|
ppPicture |
Pointer to a variable that receives the picture object's interface pointer. |
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
If the method succeeds, the caller must free the returned Picture by calling the interface Release method.
If TimeOut is INFINITE, the function's time-out interval never elapses.
Note: The frame data is retrieved from the underlying graph after the processing
filters. If the capture needs to occur before the processing is completed
use the LeadVideoCallBackFilter and place it first in the collection of
processing filters.
