Android ExoPlayer通过HTTP流式传输

2014-07-06 169 views

我试图掌握今年推出的ExoPlayer library，这样我就可以将它整合到我的应用程序中。Android ExoPlayer通过HTTP流式传输

我试图通过HTTP流式传输mp3，但到目前为止一直不成功。我不确定是否有可能，但我试图在不扩展任何基本Source/Sample类的情况下完成此操作。我的代码如下：

在我的活动

SampleSource s = new FrameworkSampleSource(this, Uri.parse("http://traffic.libsyn.com/joeroganexp/p518.mp3"), null, 1); 

// Since I only have 1 audio renderer 
ExoPlayer player = ExoPlayer.Factory.newInstance(1); 

MediaCodecAudioTrackRenderer audioRenderer = new MediaCodecAudioTrackRenderer(s); 
player.prepare(audioRenderer); 
player.setPlayWhenReady(true);

为了我的未经训练的眼睛好像我可以正确得到TrackInfo，但我有一个通过HTTP读取数据时出现问题。这似乎也似乎框架嗅探mimetype即使我接收类型'音频/ mpeg'失败。

再次，我欣赏我收到的任何方向。我意识到这些API是非常新的。

谢谢！

以下代码适用于我。虽然我很难将exoPlayer连接到用户界面。

String key = DeveloperKey.CLIENT_ID; 
    // Construct the URL for the query 
    final String BASE_URL = "https://api.soundcloud.com/tracks/101150664/stream?"; 
    final String CLIENTID_PARAM = "client_id"; 

    Uri builtUri = Uri.parse(BASE_URL).buildUpon() 
      .appendQueryParameter(CLIENTID_PARAM, key) 
      .build(); 

    Log.v(LOG_TAG, "BUILT URI FOR STREAMING: " + builtUri); 

    // Build the sample source 
    FrameworkSampleSource sampleSource = new FrameworkSampleSource(getActivity(), builtUri, null, 1); 

    // Build the track renderers 
    TrackRenderer audioRenderer = new MediaCodecAudioTrackRenderer(sampleSource, null, true); 

    // Build the ExoPlayer and start playback 
    ExoPlayer exoPlayer = ExoPlayer.Factory.newInstance(1); 
    exoPlayer.prepare(audioRenderer); 
    exoPlayer.setPlayWhenReady(true);

您是否尝试添加侦听器以便读取ExoPlayer的各种状态。我成功地用ExoPlayer取代了MediaPlayer。 – user2538359

嗨用户user2538359任何方式，你可以告诉我你是如何从mediaplayer升级到exoplayer？ – alexistkd

从现在开始使用 - 新MediaCodecAudioTrackRenderer（sampleSource，MediaCodecSelector.DEFAULT） –
