基于打包和分发方案的迁移指南Packaging and delivery scenario-based migration guidance
本文为你提供了基于打包和分发方案的指南，可帮助你从 Azure 媒体服务 v2 迁移到 v3。This article gives you scenario-based guidance for packaging and delivery that will assist you in migrating from Azure Media Services v2 to v3.
V3 API 中内容发布方式的重大更改。Major changes to the way content is published in v3 API. 新的发布模型已简化，可使用更少的实体来创建流式处理定位符。The new publishing model is simplified and uses fewer entities to create a Streaming Locator. API 缩减到只有两个实体，而之前需要四个实体。The API reduced down to just two entities vs. the four entities previously required. 内容密钥策略和流式处理定位符现在替代了对 ContentKeyAuthoriationPolicy、AssetDeliveyPolicy、ContentKey 和 AccessPolicy 的需求。Content Key Policies and Streaming Locators now replace the need for ContentKeyAuthoriationPolicy, AssetDeliveyPolicy, ContentKey, and AccessPolicy.
V3 中的打包和分发Packaging and delivery in v3
- 创建内容密钥策略。Create Content Key Policies.
- 创建流式处理定位符。Create Streaming Locators.
