版本 1.0.0

版本 1.0.0-alpha01

2021 年 10 月 27 日

发布了 androidx.media3:media3-*:1.0.0-alpha01版本 1.0.0-alpha01 中包含这些提交内容

新功能

Media3 是面向媒体支持库(包括 ExoPlayer)的新平台。首个 Alpha 版包含用于实现媒体用例的库的早期功能实现,包括:

  • ExoPlayer - 一种适用于 Android 的应用级媒体播放器,可轻松自定义和扩展。
  • 用于公开和控制播放的媒体会话功能。这一新的会话模块使用与 ExoPlayer 相同的 Player 接口。
  • 用于构建媒体播放界面的界面组件。
  • 其他库中用于 ExoPlayer 的模块封装功能,例如通过 IMA SDK 插入广告。

如需了解详情,请参阅 Media3 GitHub 项目

之前,ExoPlayer 托管在单独的 ExoPlayer GitHub 项目中。在 Media3 中,其软件包名称为 androidx.media3.exoplayer。我们计划在一段时间内继续维护和发布 ExoPlayer GitHub 项目,以便让应用有时间迁移到 Media3。Media3 取代了所有 ExoPlayer 模块,但旧版 media2 和 mediasession 扩展程序除外,后者已被新的 media3-session 模块取代。这可以实现播放器和媒体会话之间的直接集成,而无需使用适配器/连接器类。
