Exoplayer playing m3u8 files Android

Question

After trying multiple ways of playing m3u8 files using videoview and mediaplayer I decided to give up. Everytime i play the m3u8 file I only hear the voice.

Answer 1

I Have created one demo app to play m3u8 media file

First add gradle dependencies to your file

compile 'com.google.android.exoplayer:exoplayer:r2.4.0'

Create a simple layout file with storage master.m3u8 path as input and SimpleExoPlayerView view to play downloaded files.

Create a simple ExoPlayer Activity to play Files.

public class ExoPlayer  extends AppCompatActivity{
Context mContext;
SimpleExoPlayerView playerView;
EditText editText;
private ComponentListener componentListener;
private DataSource.Factory mediaDataSourceFactory;
private Handler mainHandler;
private DefaultTrackSelector trackSelector;
SimpleExoPlayer player;
private static final DefaultBandwidthMeter BANDWIDTH_METER = new        DefaultBandwidthMeter();




@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.activity_exoplayer);
   mContext =this;
   editText = (EditText) findViewById(R.id.mediaPath);
   Button btnPlay = (Button) findViewById(R.id.play);
   playerView  = (SimpleExoPlayerView)findViewById(R.id.video_view);
   mediaDataSourceFactory = buildDataSourceFactory(true);
   mainHandler = new Handler();
   componentListener = new ComponentListener();
   trackSelector = new DefaultTrackSelector();
   btnPlay.setOnClickListener(new View.OnClickListener() {
       @Override
       public void onClick(View view) {
      if(editText.getText()!=null && editText.getText().length()>0){
               initializePlayer(editText.getText().toString());
           }
       }
   });
}
   private DataSource.Factory buildDataSourceFactory(boolean useBandwidthMeter) {
   return ((AnalyticsApplication) getApplication())
           .buildDataSourceFactory(useBandwidthMeter ? BANDWIDTH_METER : null);
 }

   private void initializePlayer(String path) {
   player = ExoPlayerFactory.newSimpleInstance(mContext, trackSelector);
   player.addListener(componentListener);
//        String path = file:///storage/emulated/0/SugarBox/master.m3u8";
   Uri uri = Uri.parse(path);
   MediaSource mediaSource = buildMediaSource(uri);
   player.prepare(mediaSource, true, false);
   playerView.setPlayer(player);
 }
  private MediaSource buildMediaSource(Uri uri) {
 return new HlsMediaSource(uri, mediaDataSourceFactory, mainHandler, null);
 }
 private void releasePlayer() {
   if (player != null) {
       player.removeListener(componentListener);
       player.release();
       player = null;
   }
   }



 @Override
 public void onStart() {
   super.onStart();
   if (Util.SDK_INT > 23) {
       if(editText.getText()!=null && editText.getText().length()>0){
           initializePlayer(editText.getText().toString());
       }
   }
 }




@Override
   public void onResume() {
   super.onResume();
   if ((Util.SDK_INT <= 23 || player == null)) {
       if(editText.getText()!=null && editText.getText().length()>0){
           initializePlayer(editText.getText().toString());
       }
   }
 }



@Override
 public void onPause() {
   super.onPause();
   if (Util.SDK_INT <= 23) {
       releasePlayer();
   }
}



 @Override
public void onStop() {
   super.onStop();
   if (Util.SDK_INT > 23) {
       releasePlayer();
   }
