The Render method renders the current filter graph.
HRESULT Render( DWORD dwFlags );
[in] Value that specifies how the filter graph renders the current multimedia stream. This value currently must be AMMSF_NOCLOCK.
Returns S_OK if successful or E_INVALIDARG if the dwFlags parameter is invalid.
This method renders each of the source streams for a stream of type STREAMTYPE_WRITE. This can be called several times, for instance, each time a source stream is added, the stream is not set into running mode. Use the IMultiMediaStream::SetState method to set the stream into running mode after calling this method.
The AMMSF_RENDERALLSTREAMS flag will create default rendering streams for video and audio if they do not exist.
