Lijst met kenmerken
[De functie die is gekoppeld aan deze pagina, Windows Media Format 11 SDK, is een verouderde functie. Het is vervangen door Source Reader en Sink Writer. Bronlezer en Sink Writer zijn geoptimaliseerd voor Windows 10 en Windows 11. Microsoft raadt ten zeerste aan om nieuwe code te gebruiken bronlezer en Sink Writer- in plaats van Windows Media Format 11 SDK, indien mogelijk. Microsoft stelt voor dat bestaande code die gebruikmaakt van de verouderde API's, indien mogelijk opnieuw worden geschreven om de nieuwe API's te gebruiken.]
De vooraf gedefinieerde kenmerken die bij deze SDK zijn opgenomen, worden alfabetisch weergegeven in de volgende tabel. Elk kenmerk heeft een naam, een globale id en een gegevenstype zoals gedefinieerd door het juiste lid van de opsomming WMT_ATTR_DATATYPE. Sommige kenmerken maken geen gebruik van een eenvoudig gegevenstype of worden opgemaakt volgens een structuur. Vermeldingen voor deze kenmerken vermelden een structuurnaam in de kolom gegevenstype met het gegevenstype dat wordt gebruikt om de waarde tussen haakjes in te stellen.
Notitie
Zie LIJST met DRM-kenmerken voor een tabel met alle DRM-gerelateerde kenmerken.
Wanneer u met deze kenmerken programmeert, moet u de globale id gebruiken in plaats van de naam te gebruiken als letterlijke tekenreeks. Door de globale id te gebruiken, resulteert elke typografische fouten in een fout tijdens het compileren.
