IMediaSeeking::GetDuration
A version of this page is also available for
4/8/2010
This method retrieves the length of time that the media stream will play.
Syntax
HRESULT GetDuration(
LONGLONG* pDuration
);
Parameters
- pDuration
[out] Returned length of the media stream.
Return Value
Returns an HRESULT value that depends on the implementation of the interface. The default DirectShow implementation returns E_POINTER if the pointer argument is NULL, or another COM return code otherwise.
Remarks
The duration assumes normal playback speed, and it is therefore unaffected by the rate. Although IMediaSeeking allows filters to be seeked in media time, it still requires that the media samples it sends downstream are time stamped appropriately.
