IMFMediaEngine::GetDuration method (mfmediaengine.h)
Gets the duration of the media resource.
Syntax
double GetDuration();
Return value
Returns the duration, in seconds. If no media data is available, the method returns not-a-number (NaN). If the duration is unbounded, the method returns an infinite value.
Remarks
This method corresponds to the duration attribute of the HTMLMediaElement interface in HTML5.
If the duration changes, the Media Engine sends an MF_MEDIA_ENGINE_EVENT_DURATIONCHANGE event. See IMFMediaEngineNotify::EventNotify.
