Remarks

This method renders the data from a specified output pin, adding new filters to the graph as needed. Filters are tried in the same order as for the IGraphBuilder::Connect method. For more information, see Intelligent Connect.

During the connection process, the Filter Graph Manager ignores pins on intermediate filters if the pin name begins with a tilde (~). For more information, see PIN_INFO.
