How to save or load properties of filter in DirectShow

Question

I have a source filter in the graph of my application. I could show the properties page by using standard API (from oleaut32.dll - OleCreatePropertyFrame, see Displaying a Filter's Property Pages).

But how to save/serialize and load/deserialize the filter properties from code? I'm using DirectShow.NET to build graph.

Answer 1

Query IPersistStream interface from the filter and use IPersistStream.Save to request writing of persistent settings into stream. Load back similarly.
