使用Exoplayer设置流式传输mp4视频和播放文件的标头

Question

Api有一个我需要设置的令牌头，但视频没有加密。我有两个问题：如何使用exoplayer从磁盘播放.mpg，.mpeg，.3gp，.mov和其他文件？如何使用exoplayer设置标头并从网址流式传输mp4视频？

Answer 1

想出答案：

DefaultHttpDataSource source = new DefaultHttpDataSource(userAgent, null);
    source.setRequestProperty("Authorization", "your auth code");
    source.setRequestProperty("Accept", "...");

    ExtractorSampleSource sampleSource = new ExtractorSampleSource(uri, source, extractor, 2,
            BUFFER_SIZE);
    MediaCodecVideoTrackRenderer videoRenderer = new MediaCodecVideoTrackRenderer(sampleSource,
            null, true, MediaCodec.VIDEO_SCALING_MODE_SCALE_TO_FIT_WITH_CROPPING, 5000, null, player.getMainHandler(),
            player, 50);
    MediaCodecAudioTrackRenderer audioRenderer = new MediaCodecAudioTrackRenderer(sampleSource,
            null, true, player.getMainHandler(), player);

Answer 2

  // 1. Create a default TrackSelector
    BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
    TrackSelection.Factory videoTrackSelectionFactory = new 
  AdaptiveTrackSelection.Factory(bandwidthMeter);
    TrackSelector trackSelector = new 
  DefaultTrackSelector(videoTrackSelectionFactory);

  // 2. Create a default LoadControl
    LoadControl loadControl = new DefaultLoadControl();

 // 3. Create the player
    player = ExoPlayerFactory.newSimpleInstance(this, trackSelector,  
   loadControl);
    simpleExoPlayerView = new SimpleExoPlayerView(this);
    simpleExoPlayerView = (SimpleExoPlayerView)
  findViewById(R.id.player_view);

  //Set media controller
    simpleExoPlayerView.setUseController(true);
    simpleExoPlayerView.requestFocus();

   // Bind the player to the view.
    simpleExoPlayerView.setPlayer(player); 

   String username = "username";
    String password = "password";

    // encrypt Authdata
    byte[] toEncrypt = (username + ":" + password).getBytes();
    encoded = Base64.encodeToString(toEncrypt, Base64.DEFAULT);
    DefaultHttpDataSourceFactory dataSourceFactory = new 
    DefaultHttpDataSourceFactory(Util.getUserAgent(this,   
    "exoplayer2example"));

    DefaultHttpDataSource source = new  DefaultHttpDataSource(Util.getUserAgent(this, "exoplayer2example"),null);
    dataSourceFactory.setDefaultRequestProperty("Authorization","Basic "+encoded);
    ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();
    MediaSource videoSource = new ExtractorMediaSource(Uri.parse("https://example.com/assets/video/SampleVideo.mp4"),
            dataSourceFactory, extractorsFactory, null, null);
    final LoopingMediaSource loopingSource = new LoopingMediaSource(videoSource);
    exoplayer.prepare(videoSource);

如何使用exoplayer设置标头并从网址流式传输mp4视频？

我实施了基本授权，所以：

private SimpleExoPlayer player;
private PlayerView playerView;

private void initializePlayer() {
    player = ExoPlayerFactory.newSimpleInstance(
            new DefaultRenderersFactory(this),
            new DefaultTrackSelector(),
            new DefaultLoadControl());
    playerView.setPlayer(player);
    player.setPlayWhenReady(true);
    player.seekTo(0, 0);

    Uri uri = Uri.parse(getString(R.string.media_url));
    MediaSource mediaSource = buildMediaSource(uri);
    player.prepare(mediaSource, true, false);
}

private MediaSource buildMediaSource(final Uri uri) {
    HttpDataSource.BaseFactory myDSFactory = new HttpDataSource.BaseFactory() {
        @Override
        protected HttpDataSource createDataSourceInternal(HttpDataSource.RequestProperties defaultRequestProperties) {
            byte[] toEncrypt = uri.getUserInfo().getBytes();
            String encoded = "Basic " + Base64.encodeToString(toEncrypt, Base64.DEFAULT).trim();
            DefaultHttpDataSourceFactory dsf = new DefaultHttpDataSourceFactory("exoplayer-codelab");
            HttpDataSource ds = dsf.createDataSource();
            ds.setRequestProperty("Authorization", encoded);
            return ds;
        }
    };

    ExtractorMediaSource.Factory emf = new ExtractorMediaSource.Factory(myDSFactory);
    return emf.createMediaSource(uri);
}
