ExoPlayer中播放rtmps链接的Android源代码

BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
TrackSelection.Factory videoTrackSelectionFactory =
        new AdaptiveTrackSelection.Factory(bandwidthMeter);
TrackSelector trackSelector =
        new DefaultTrackSelector(videoTrackSelectionFactory);
player = ExoPlayerFactory.newSimpleInstance(this, trackSelector);
PlayerView playerView = findViewById(R.id.simple_player);
playerView.setPlayer(player);
RtmpDataSourceFactory rtmpDataSourceFactory = new RtmpDataSourceFactory();

  path = "rtmps:///hostname.net/..../64174.mp4";

MediaSource videoSource = new ExtractorMediaSource.Factory(rtmpDataSourceFactory)
        .createMediaSource(Uri.parse(path));

player.prepare(videoSource);

player.setPlayWhenReady(true);
