Android ExoPlayer streaming mp3 su HTTP

2014-07-06 11 views

Sto cercando di ottenere una presa sul nuovo ExoPlayer library introdotto quest'anno al Google I/O 2014 in modo che possa incorporarlo nella mia applicazione.Android ExoPlayer streaming mp3 su HTTP

Sto tentando di riprodurre in streaming un mp3 su HTTP, ma finora non ha avuto esito positivo. Non sono sicuro che sia possibile, ma sto cercando di ottenerlo senza estendere nessuna delle classi di base Source/Sample. Il mio codice è il seguente:

nella mia attività

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);

Per il mio occhio inesperto sembra che posso ottenere il trackinfo correttamente, ma sto avendo un problema nel leggere i dati su HTTP. Sembra anche che il modo in cui il framework annusa che il mimetype stia fallendo anche se ricevo il tipo 'audio/mpeg'.

Ancora una volta, apprezzo ogni direzione che ricevo. Mi rendo conto che queste API sono molto nuove.

Grazie!

Il codice seguente ha funzionato per me. Però ho difficoltà ad agganciare l'exoPlayer all'interfaccia utente.

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);

Hai provato ad aggiungere Listener per leggere il vari stato di ExoPlayer. Sono riuscito a sostituire MediaPlayer con ExoPlayer. – user2538359

hi user user2538359 in qualsiasi modo puoi mostrarmi come sei aggiornato da mediaplayer a exoplayer? – alexistkd

A partire da ora per l'utilizzo di origine - nuovo MediaCodecAudioTrackRenderer (sampleSource, MediaCodecSelector.DEFAULT) –
