Attributlista
[Funktionen som är associerad med den här sidan, Windows Media Format 11 SDK, är en äldre funktion. Det har ersatts av Source Reader och Sink Writer. Source Reader och Sink Writer har optimerats för Windows 10 och Windows 11. Microsoft rekommenderar starkt att ny kod använder Source Reader och Sink Writer i stället för Windows Media Format 11 SDK, när det är möjligt. Microsoft föreslår att befintlig kod som använder äldre API:er skrivs om för att använda de nya API:erna om möjligt.]
De fördefinierade attribut som ingår i denna SDK visas alfabetiskt i följande tabell. Varje attribut har ett namn, en global identifierare och en datatyp som definieras av lämplig medlem i WMT_ATTR_DATATYPE uppräkning. Vissa attribut använder inte en enkel datatyp eller formateras enligt en struktur. Poster för dessa attribut visar ett strukturnamn i kolumnen datatyp med den datatyp som används för att ange värdet inom parenteser.

Se DRM-attributlista för en tabell med alla DRM-relaterade attribut.
När du programmerar med dessa attribut bör du använda den globala identifieraren i stället för att använda namnet som en strängliteral. Med hjälp av den globala identifieraren resulterar eventuella typografiska fel i ett fel vid kompileringstillfället.
