Exoplayer reproduce archivos m3u8 Android

Posterior a de esta extensa búsqueda de datos dimos con la respuesta este enigma que presentan muchos los lectores. Te regalamos la solución y deseamos que te resulte de mucha apoyo.

Solución:

En Android 4.1+, puede usar esta biblioteca https://github.com/brianwernick/ExoMedia/. El ejemplo mencionado en la página Léame debería ser suficiente para comenzar. He reproducido ese fragmento de código con algunas adiciones / modificaciones.

            private void setupVideoView() 
                EMVideoView emVideoView = (EMVideoView)findViewById(R.id.video_play_activity_video_view);
                emVideoView.setOnPreparedListener(this);

                //Enter your m3u8 URL below
                emVideoView.setVideoURI(Uri.parse("http://SOMESERVER/playlist.m3u8"));
            

            @Override
            public void onPrepared(MediaPlayer mp) 
                //Starts the video playback as soon as it is ready
                emVideoView.start();
            

            @Override
            public void onPause() 
                super.onPause();
                //Pause Video Playback
                emVideoView.pause();
            

He creado una aplicación de demostración para reproducir archivos multimedia m3u8

Primero agregue las dependencias de Gradle a su archivo

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

Cree un archivo de diseño simple con la ruta de almacenamiento master.m3u8 como entrada y la vista SimpleExoPlayerView para reproducir archivos descargados.

Cree una actividad sencilla de ExoPlayer para reproducir archivos.
