IPersistMediaPropertyBag::Save method (strmif.h)
[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]
The Save method saves properties from the filter into the media property bag.
Syntax
HRESULT Save(
[in] IMediaPropertyBag *pPropBag,
[in] BOOL fClearDirty,
[in] BOOL fSaveAllProperties
);
Parameters
[in] pPropBag
Pointer to the IMediaPropertyBag interface of a media property bag created by the caller.

Remarks
If you call this method on the AVI Splitter filter or the WAVE Parser, the filter reads any INFO and DISP chunks from the file and stores them in the media property bag. You can use the IMediaPropertyBag::EnumProperty method to retrieve the chunks.
The AVI Mux filter does not implement this method.
