無法在android平臺上流式傳輸.m3u8文件

Question

我試圖在android平臺上實現http實時流式傳輸。但是對於.m3u8文件的這個（http://rajsimsan.site90.net/stream.m3u8）鏈接，我的模擬器沒有播放視頻。這裏是主要的java代碼。

Answer 1

看看Vitamio。他們有一個庫，你可以使用 - 即使在Android 2.1設備上 - 可以讓你玩m3u8 feed（等等）。

不幸的是，模擬器不支持vitamio庫，因此您必須在物理設備上進行測試（或訂閱第三方真實設備測試服務）。

Answer 2

沒有vitamio，我們不能沒有m3u8流？
