PlayReady 用戶端支援的 MP4 格式

  • 發行項

格式

[格式]

  • MP4 型資產。 慣用 CMAF。
  • DASH 資訊清單。
  • 資產上的相同金鑰 - 金鑰不會隨著時間而變更。
  • 所有曲目和標記法的相同單一索引鍵 (位元速率) ，或不同追蹤和表示 (位元速率) 的不同索引鍵。 例如，不同的金鑰可用於高於 1080p 的所有視訊播放軌，以限制特定用戶端的 4K 解析度存取。

支援

在 1507 版或更新 <mspr:pro> 版本中支援具有靜態資訊清單的 Live Profile 標籤， (隨選內容) 。

在 1703 版或更新 <mspr:pro> 版本中支援具有動態資訊清單的即時設定檔標籤， (Live 內容) 。

DASH 資訊清單包含 PlayReady 物件，包括使用 <mspr:pro> 節點中的 <Period> 標籤的 PlayReady 標頭。 如果不同的索引鍵用於不同的曲目或位元速率，DASH 資訊清單可能會改為在多個 <AdaptationSet> 或 <Representation> 節點中有多個 PlayReady 物件。

注意

可以在不同 <AdaptationSet> 節點的 init 區段內插入 PlayReady 物件。 如果在 init 區段和資訊清單中找到 PlayReady 物件，則資訊清單中的物件優先。


RS5 或更高版本支援具有隨選和 Live 資產標準 <cenc:pssh> 標籤的 DASH 資訊清單。 在此情況下，在基底 64 中保護的 pssh 方塊整個內容會包含在資訊清單中。 它不只是 PlayReady 物件。

為了提升相容性，Microsoft 建議您產生 DASH 資訊清單，其中包含 和 <cenc:pssh> 標籤中重複的 <mspr:pro> PlayReady 物件。
