Attributliste
[Das dieser Seite zugeordnete Feature Windows Media Format 11 SDK-ist ein Legacyfeature. Es wurde von Source Reader und Sink Writerersetzt. Source Reader und Sink Writer wurden für Windows 10 und Windows 11 optimiert. Microsoft empfiehlt dringend, dass neuer Code Source Reader und Sink Writer- anstelle Windows Media Format 11 SDK-verwendet werden soll. Microsoft schlägt vor, dass vorhandener Code, der die Legacy-APIs verwendet, um die neuen APIs zu verwenden, falls möglich umgeschrieben werden.]
Die vordefinierten Attribute, die in diesem SDK enthalten sind, werden alphabetisch in der folgenden Tabelle dargestellt. Jedes Attribut weist einen Namen, einen globalen Bezeichner und einen Datentyp auf, der durch das entsprechende Element der WMT_ATTR_DATATYPE-Aufzählung definiert ist. Einige Attribute verwenden keinen einfachen Datentyp oder sind entsprechend einer Struktur formatiert. Einträge für diese Attribute enthalten einen Strukturnamen in der Datentypspalte mit dem Datentyp, der zum Festlegen des Werts in Klammern verwendet wird.
Anmerkung
Eine Tabelle aller DRM-bezogenen Attribute finden Sie unter DRM-Attributliste.
Wenn Sie mit diesen Attributen programmieren, sollten Sie den globalen Bezeichner anstelle des Namens als Zeichenfolgenliteral verwenden. Durch die Verwendung des globalen Bezeichners führen alle typografischen Fehler zur Kompilierungszeit zu einem Fehler.
