E/ExoPlayerImplInternal: Source error com.google.android.exoplayer2.upstream.HttpDataSource$InvalidResponseCodeException: Response code: 404

问题

I am trying the play the video by the exo Player, but it gives me this error:-

E/ExoPlayerImplInternal: Source error.
InvalidResponseCodeException: Response code: 404

This is my Activity Class :-

public class VideoActivity extends AppCompatActivity implements VideoRendererEventListener {
    private String mVideoUrl;
    private SimpleExoPlayerView simpleExoPlayerView;
    private SimpleExoPlayer player;
    private static final String TAG = "AMAN";


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

    if (getIntent() != null)
        mVideoUrl = getIntent().getStringExtra("VideoUrl");




    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 = new SimpleExoPlayerView(this);
    simpleExoPlayerView = (SimpleExoPlayerView) findViewById(R.id.player_view);


    simpleExoPlayerView.setUseController(true);
    simpleExoPlayerView.requestFocus();


    simpleExoPlayerView.setPlayer(player);



    Uri mp4VideoUri =Uri.parse(mVideoUrl);

    DefaultBandwidthMeter bandwidthMeterA = new DefaultBandwidthMeter();

    DefaultDataSourceFactory dataSourceFactory = new DefaultDataSourceFactory(this, Util.getUserAgent(this, "exoplayer2example"), bandwidthMeterA);

    ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();


    MediaSource videoSource = new HlsMediaSource(mp4VideoUri, dataSourceFactory, 1, null, null);
    final LoopingMediaSource loopingSource = new LoopingMediaSource(videoSource);




   player.prepare(loopingSource);
                    player.setPlayWhenReady(true);

}

Does anyone know what is wrong here?

回答1:

You must use the "final" modifier for your link.

`protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_player);

    final String VIDEO_URL = getIntent().getExtras().getString("URL");

    playerView = findViewById(R.id.exo_player);
    simpleExoPlayer = ExoPlayerFactory.newSimpleInstance(this);
    playerView.setPlayer(simpleExoPlayer);
    DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(this,
            Util.getUserAgent(this, "appname"));
    MediaSource videoSource  = new ExtractorMediaSource.Factory(dataSourceFactory).createMediaSource(Uri.parse(VIDEO_URL));
    simpleExoPlayer.prepare(videoSource);
    simpleExoPlayer.setPlayWhenReady(true);
}`
