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 HRESULTvalue 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 IMediaSeekingallows filters to be seeked in media time, it still requires that the media samples it sends downstream are time stamped appropriately.

Requirements

Windows Embedded CE Windows CE 2.12 and later
Windows Mobile Pocket PC for Windows Mobile Version 5.0 and later, Smartphone for Windows Mobile Version 5.0 and later
Note Microsoft DirectShow applications and DirectShow filters have different include file and Library requirements
For more information, see Setting Up the Build Environment,
Version 2.12 requires DXPAK 1.0 or later
