我正在使用 MediaPlayer 使用 HLS 媒体直播视频。流文件的扩展名为 .m3u8。就我而言，多媒体文件无法在 Android OS 版本 MarshMallow 和 Lollipop 中提供流媒体。高于 OS 版本 M 的相同文件提供了完美的流媒体。

我正在寻找答案的问题如下

  1. 是硬件相关的问题吗？
  2. 它只是与操作系统相关的问题吗？
  3. 为什么有些 m3u8 url 在 MediaPlayer 实现上运行良好，而有些则不行？

我在这里共享第一个工作的文件和第二个不工作的文件。

1. 这是第一个正常工作的 URL：https ://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8

可以在此处找到文件的内部详细信息
