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.
