ltmmCapture_Notify Constants

typedef enum _ltmmCapture_Notify 
{ 
   ltmmCapture_Notify_Started, 
   ltmmCapture_Notify_Complete, 
   ltmmCapture_Notify_ErrorAbort, 
   ltmmCapture_Notify_Progress, 
   ltmmCapture_Notify_MediaEvent, 
   ltmmCapture_Notify_RestartApplication 
} ltmmCapture_Notify;

The ltmmCapture_Notify constants define the WPARAM parameter used in notification messages.

Constant	Description
ltmmCapture_Notify_Started	[0] Indicates that capturing process has started.
ltmmCapture_Notify_Complete	[1] Indicates a successful completion of the capturing process.
ltmmCapture_Notify_ErrorAbort	[2] Indicates that a capture error has occurred. The message LPARAM value contains the HRESULT error code.
ltmmCapture_Notify_Progress	[3] Indicates the current progress of the conversion process. The message LPARAM value contains the current capture time, in milliseconds.
ltmmCapture_Notify_MediaEvent	[4] Indicates an event related to the current media and the operations performed on it. The message LPARAM value is a pointer to an ltmmMediaEvent structure. For a list of all possible values of the event code and parameters refer to the ltmmMediaEventCode Constants. Currently, only DVD specific events are supported.
ltmmCapture_Notify_RestartApplication	[5] Indicates a settings change in the capture device requires an application restart. Failure to restart the application after receiving this event will result in unpredictable behaviour.
