Android Exoplayer 2 UDP解码问题

Question

我是ExoPlayer的新手，我目前正在使用它来播放本地的Udp流（来自法国数字电视:1080p5-10 mbps的可变比特率）我设法在不同的设备上播放一些Udp流和一些测试视频，这些视频来自http://jell.yfish.us/。我已经用HLS和Udp流进行了一些不同的视频解码测试，并使用以下Udp代码：

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.myactivity);

    sufaceview = (SurfaceView) findViewById(R.id.surfaceView2);


    BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
    TrackSelection.Factory videoTrackSelectionFactory =
            new AdaptiveTrackSelection.Factory(bandwidthMeter);
    TrackSelector trackSelector =
            new DefaultTrackSelector(videoTrackSelectionFactory);

    LoadControl loadControl = new DefaultLoadControl(
            new DefaultAllocator(true, C.DEFAULT_BUFFER_SEGMENT_SIZE),
            15000, 60000, 2500, 6000);


    player = ExoPlayerFactory.newSimpleInstance(this, trackSelector, loadControl);


    Uri uri =
            Uri.parse
                    ("udp://@239.192.2.2:1234");

    final DefaultBandwidthMeter bandwidthMeterA = new DefaultBandwidthMeter();

    DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(this,
            Util.getUserAgent(this, "teveolauncher"), bandwidthMeterA);

    extractorsFactory = new DefaultExtractorsFactory();

    DataSource.Factory udsf = new UdpDataSource.Factory() {
        @Override
        public DataSource createDataSource() {
            return new UdpDataSource(null, 3000, 100000);
        }
    };
    ExtractorsFactory tsExtractorFactory = new ExtractorsFactory() {
        @Override
        public Extractor[] createExtractors() {
            return new TsExtractor[]{new TsExtractor(MODE_SINGLE_PMT,
                    new TimestampAdjuster(0), new DefaultTsPayloadReaderFactory())};
        }
    };



    MediaSource videoSource = new ExtractorMediaSource
            (uri, udsf, tsExtractorFactory, null, null);

    player.setVideoSurfaceView(sufaceview);
    player.prepare(videoSource);
    player.setPlayWhenReady(true);

}

    DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(this,
            Util.getUserAgent(this, "teveolauncher"), bandwidthMeterA);

    MediaSource videoSource = new HlsMediaSource
            (uri, dataSourceFactory, null, null);

Answer 1

    Uri uri = Uri.parse("udp://@239.192.2.2:1234");

我认为UDP不是一个协议--它是一种传输，（像TCP一样）。也不能使用tcp：//host:port/URL。

还是管用？
