修改samples.java来自：

new Sample("test 2", "",
             "http://dash.edgesuite.net/dash264/TestCases/1a/netflix/exMPD_BIP_TC1.mpd",
             DemoUtil.TYPE_DASH_VOD, false, false),

2 个答案:

答案 0 :(得分：0)

ExoPlayer不喜欢MPD。它实际上属于：

https://github.com/google/ExoPlayer/issues/2

虽然我真的不认为我们真的想要处理这种MPD。 MPD不提供关于每个流的初始化和索引数据的位置的任何指示。除非我遗漏了某些东西，否则这意味着玩家必须向每个URL发出无限范围请求并读取，直到找到它们为止。这真的不太理想，IMO MPD应该被修复以包含这些信息。

答案 1 :(得分：0)

（重写）

我已经能够使用当前的'dev'分支播放至少一个MPD格式文件。这是dash.js sources.json文件中的一个。

添加到Samples.java文件的参数是：

新样本（“DASH-Sintel 480p”，“uid：misc：sintel480”，          “http://dash.edgesuite.net/digitalprimates/fraunhofer/480p_video/heaac_5_1_with_video/Sintel/sintel_480p_heaac5_1.mpd”，          DemoUtil.TYPE_DASH_VOD，false，true），
