Question

我正在尝试在Android中传输实时视频。详细信息 - H264 - Mp4格式 - demuxed。

我正在使用this code

问题：

我可以在exoplayer中播放这种格式的视频吗？
我应该使用哪个库来直播视频？

使用Exoplayer播放视频的代码

    {
        Handler mainHandler = new Handler();
        BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
        TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveTrackSelection.Factory(bandwidthMeter);
        TrackSelector trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);
        LoadControl loadControl = new DefaultLoadControl();
        player = ExoPlayerFactory.newSimpleInstance(this, trackSelector, loadControl);
        simpleExoPlayerView = (SimpleExoPlayerView) findViewById(R.id.player_view);
        simpleExoPlayerView.setPlayer(player);
        DefaultBandwidthMeter defaultBandwidthMeter = new DefaultBandwidthMeter();
        DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(this,
                Util.getUserAgent(this, "Exo2"), defaultBandwidthMeter);
        ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();
        HlsMediaSource hlsMediaSource = new HlsMediaSource(Uri.parse(hlsVideoUri), dataSourceFactory, mainHandler, new AdaptiveMediaSourceEventListener() {
            @Override
            public void onLoadStarted(DataSpec dataSpec, int dataType, int trackType, Format trackFormat, int trackSelectionReason, Object trackSelectionData, long mediaStartTimeMs, long mediaEndTimeMs, long elapsedRealtimeMs) {

            }

            @Override
            public void onLoadCompleted(DataSpec dataSpec, int dataType, int trackType, Format trackFormat, int trackSelectionReason, Object trackSelectionData, long mediaStartTimeMs, long mediaEndTimeMs, long elapsedRealtimeMs, long loadDurationMs, long bytesLoaded) {

            }

            @Override
            public void onLoadCanceled(DataSpec dataSpec, int dataType, int trackType, Format trackFormat, int trackSelectionReason, Object trackSelectionData, long mediaStartTimeMs, long mediaEndTimeMs, long elapsedRealtimeMs, long loadDurationMs, long bytesLoaded) {

            }

            @Override
            public void onLoadError(DataSpec dataSpec, int dataType, int trackType, Format trackFormat, int trackSelectionReason, Object trackSelectionData, long mediaStartTimeMs, long mediaEndTimeMs, long elapsedRealtimeMs, long loadDurationMs, long bytesLoaded, IOException error, boolean wasCanceled) {

            }

            @Override
            public void onUpstreamDiscarded(int trackType, long mediaStartTimeMs, long mediaEndTimeMs) {

            }

            @Override
            public void onDownstreamFormatChanged(int trackType, Format trackFormat, int trackSelectionReason, Object trackSelectionData, long mediaTimeMs) {

            }
        });

        player.addListener(this);
        player.prepare(hlsMediaSource);
        simpleExoPlayerView.requestFocus();
        player.setPlayWhenReady(true);
    }

当我执行此代码时 - 似乎exoplayer正在下载一些东西，因为我可以看到缓冲，但我从不播放任何视频或音频。日志：

我们可以在exoplayer中播放H264视频吗？
