Formatos baseados em MP4 suportados por clientes PlayReady

Formatos

Formato

  • Recurso baseado em MP4. O CMAF é preferido.
  • Manifesto DASH.
  • As mesmas chaves ao longo do ativo - As chaves não mudam ao longo do tempo.
  • Mesma chave única para todas as faixas e representações (bitrates), ou chaves diferentes para diferentes faixas e representações (bitrates). Por exemplo, uma chave diferente pode ser usada para todas as faixas de vídeo acima de 1080p para restringir o acesso à resolução 4K para determinados clientes.

Suportado

Suportado na versão 1507 ou superior com a etiqueta "<mspr:pro>" para o Live Profile com manifestos estáticos (conteúdo On-Demand).

Suportado na versão 1703 ou superior com a <mspr:pro> tag para o Live Profile com manifestos dinâmicos (conteúdo ao vivo).

O manifesto DASH contém um objeto PlayReady, incluindo um cabeçalho PlayReady, que utiliza a etiqueta <mspr:pro> dentro do nó <Period>. Se forem usadas chaves diferentes para faixas ou diferentes bitrates, o manifesto DASH pode ter múltiplos objetos PlayReady nos múltiplos elementos <AdaptationSet> ou <Representation>.

Observação

É possível inserir os objetos PlayReady dentro dos segmentos de inicialização dos diferentes <AdaptationSet> nós. Se os objetos PlayReady forem encontrados nos segmentos iniciais e no manifesto, os do manifesto terão precedência.


As manifestações DASH com uma tag padrão <cenc:pssh> para ativos On-Demand e Live são suportadas na versão RS5 ou superior. Neste caso, todo o conteúdo de uma caixa pssh blindada na base 64 está incluído no manifesto. Não é apenas um objeto PlayReady.

Para aumentar a compatibilidade, a Microsoft recomenda que gere manifestos DASH que incluam os objetos PlayReady duplicados nas tags <mspr:pro> e <cenc:pssh>.
