CPersistStream.Save method
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

);
Parameters
-
pStm

-
Flag that indicates whether to reset the current stream's dirty flag; TRUE means to reset it. (When the method is called as part of a Save operation, the value is typically TRUE; when called as part of a Save As operation, the value is typically FALSE.)

Remarks
This member function implements the IPersistStream::Save method. It calls WriteInt with the software version, calls CPersistStream::WriteToStream with the stream in pStm, and resets mPS_fDirty.
