无法在 android 平台上流式传输 .m3u8 文件

Question

我正在尝试在 android 平台上实现 http 直播。但是对于 .m3u8 文件的这个（http://rajsimsan.site90.net/stream.m3u8）链接，我的模拟器没有播放视频。这是主要的java代码。

Answer 1

如果没有 vitamio，我们不能在没有 m3u8 的情况下进行流式传输吗？

Answer 2

看看Vitamio。他们有一个您可以使用的库 — 甚至在 Android 2.1 设备上 — 允许您播放 m3u8 提要（以及其他内容）。

很遗憾，模拟器不支持 vitamio 库，因此您必须在物理设备上进行测试（或订阅第三方真机测试服务）。
