com.google.android.exoplayer2.source.UnrecognizedInputFormatException: [英] com.google.android.exoplayer2.source.UnrecognizedInputFormatException:

问题描述

我需要使用.cd格式的exoplayer复制现场表演.

I need to reproduce a live show with exoplayer in format .mpd.

但我收到此错误:

com.google.android.exoplayer2.source.UnrecognizedInputFormatException: 没有可用的提取器(MatroskaExtractor， FragmentedMp4Extractor，Mp4Extractor，Mp3Extractor，AdtsExtractor， Ac3Extractor，TsExtractor，FlvExtractor，OggExtractor，PsExtractor， WavExtractor)可以读取流.

com.google.android.exoplayer2.source.UnrecognizedInputFormatException: None of the available extractors (MatroskaExtractor, FragmentedMp4Extractor, Mp4Extractor, Mp3Extractor, AdtsExtractor, Ac3Extractor, TsExtractor, FlvExtractor, OggExtractor, PsExtractor, WavExtractor) could read the stream.

我不知道为什么！

这是我的代码:

public class MainActivity extends AppCompatActivity {

    SimpleExoPlayer exoPlayer;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        SimpleExoPlayerView exoPlayerView;



        exoPlayerView = (SimpleExoPlayerView) findViewById(R.id.exo_player_view);
        exoPlayerView.setResizeMode(AspectRatioFrameLayout.RESIZE_MODE_FILL);

        try {


            BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
            TrackSelector trackSelector = new DefaultTrackSelector(new AdaptiveTrackSelection.Factory(bandwidthMeter));
            exoPlayer = ExoPlayerFactory.newSimpleInstance(this, trackSelector);

            Uri videoURI = Uri.parse("blablabla/manifest.mpd");

            DefaultHttpDataSourceFactory dataSourceFactory = new DefaultHttpDataSourceFactory("exoplayer_video");
            ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();
            MediaSource mediaSource = new ExtractorMediaSource(videoURI, dataSourceFactory, extractorsFactory, null, null);

            exoPlayerView.setPlayer(exoPlayer);
            exoPlayer.prepare(mediaSource);
            exoPlayer.setPlayWhenReady(true);
        }catch (Exception e){
            Log.e("MainAcvtivity"," exoplayer error "+ e.toString());
        }

    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        exoPlayer.stop();
    }
    @Override
    protected void onPause() {
        super.onPause();
        exoPlayer.stop();
    }
}

推荐答案

.mpd通常指向DASH清单，这是一种自适应格式.清单列出了播放器可以适应给定带宽条件的不同质量的媒体表示.

.mpd is commonly pointing to a DASH manifest which is an adaptive format. The manifest lists media representations of different qualities with which the player can adapt to given bandwidth conditions.

要播放DASH清单(.mpd)，请创建DASH特定的媒体源.

To play a DASH manifest (.mpd) you create a DASH specific media source.

使用DashMediaSource代替ExtractorsMediaSource:

// meter bandwidth with media files (video/audio)
DefaultHttpDataSourceFactory mediaDataSourceFactory = new DefaultHttpDataSourceFactory(
    Util.getUserAgent(this, "stackoverflow"), BANDWIDTH_METER);
// do not meter bandwidth for manifest loading
DefaultHttpDataSourceFactory manifestDataSourceFactory = new DefaultHttpDataSourceFactory(
    Util.getUserAgent(this, "stackoverflow"));
// create the media source for DASH
MediaSource mediaSource = new DashMediaSource.Factory(
    new DefaultDashChunkSource.Factory(mediaDataSourceFactory),
    manifestDataSourceFactory)
    .createMediaSource(uri, null, null);

// prepare the player
player.setPlayWhenReady(true);
player.prepare(mediaSource);
