Android Question

Android ExoPlayer stream mp3 over HTTP

I'm trying to get a grasp on the new ExoPlayer library introduced this year at Google I/O 2014 so that I can incorporate it into my application.

I'm attempting to stream an mp3 over HTTP, but so far have been unsuccessful. I'm not sure if it's possible, but I'm trying to accomplish this without extending any of the base Source/Sample classes. My code is as follows:

In my Activity

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);

To my untrained eye it seems like I can get the TrackInfo correctly, but am having a problem reading the data over HTTP. It also seems that how the framework sniffs the mimetype is failing even though I do receive type 'audio/mpeg'.

Again, I appreciate any direction I receive. I realize that these APIs are very new.



Thanks!

Answer

The following code worked for me. I'm having difficulty hooking the exoPlayer up to the UI though.

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);
