Propriedades do DRM
[O recurso associado a esta página, Windows Media Format 11 SDK, é um recurso herdado. Ele foi substituído por Leitor de Origem e Gravador de Coletor. O Leitor de Origem e o Gravador do Coletor foram otimizados para Windows 10 e Windows 11. A Microsoft recomenda fortemente que o novo código use o Leitor de Origem e o Gravador do Coletor em vez do SDK do Windows Media Format 11, quando possível. A Microsoft sugere que o código existente que usa as APIs herdadas seja reescrito para usar as novas APIs, se possível.]
A tabela a seguir lista as propriedades drm que os aplicativos podem obter ou definir ao gravar ou ler arquivos protegidos. Essas propriedades não são atributos de arquivo; eles não são gravados no cabeçalho do arquivo ASF.
