CMediaType.MatchesPartial 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]
The MatchesPartial method determines if this media type matches a partially specified media type.
Syntax
BOOL MatchesPartial(
const CMediaType *ppartial
) const;
Parameters
-
ppartial
-
Pointer to the media type to match.
Return value
Returns TRUE if the media types match. Otherwise, returns FALSE.
Remarks
The media type specified by ppartial can have a value of GUID_NULL for the major type, subtype, or format type. Any members with GUID_NULL values are not tested. (In effect, GUID_NULL acts as a wildcard.) Members with values other than GUID_NULL must match for the media type to match.
