Exo player DASH Streaming example

问题:

I'm trying to play DASH video on android devices with the ExoPlayer from Google (http://developer.android.com/guide/topics/media/exoplayer.html). The documentation is very, very poor and I cannot find some simplest working example with DASH (if someone did it). In the video (https://www.youtube.com/watch?v=6VjF638VObA#t=462) it looks simple but in reality there is a lot of unknown objects. I want to use only ExoPlayer library and without using their github demo because it is very complex and I didn't find a way to add my testing URL because all samples are from YouTube.

Thanks

Here is a simple dash playing example which will play your stream content into SimpleExoPlayerView from exoplayer-ui.

Add SimpleExoPlayerView to your layout and use the code below

    SimpleExoPlayerView exoPlayerView = (SimpleExoPlayerView) findViewById(R.id.exo_player_view);

    DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(this, Util.getUserAgent(this, "ExoPlayer"));
    Uri uri = Uri.parse("http://your_host/dash/stream.mpd");
    DashMediaSource dashMediaSource = new DashMediaSource(uri, dataSourceFactory,
            new DefaultDashChunkSource.Factory(dataSourceFactory), null, null);

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

    SimpleExoPlayer simpleExoPlayer = ExoPlayerFactory.newSimpleInstance(this, trackSelector);

    exoPlayerView.setPlayer(simpleExoPlayer);
    simpleExoPlayer.prepare(dashMediaSource);

Also add the dependencies to your build.gradle

compile 'com.google.android.exoplayer:exoplayer-core:r2.4.0'
compile 'com.google.android.exoplayer:exoplayer-dash:r2.4.0'
compile 'com.google.android.exoplayer:exoplayer-hls:r2.4.0'
compile 'com.google.android.exoplayer:exoplayer-smoothstreaming:r2.4.0'
compile 'com.google.android.exoplayer:exoplayer-ui:r2.4.0'

Actually, it is quite simple to add your testing URL to the ExoPlayer demo application available in Github.
