ExoPlayer - play 10 files one after another

Question

I have 10 video i need to play, once one is done, the next one starts to play.

I'm using Google's ExoPlayer, I use the example in the DEMO @ GitHub. I can play 1 video but if i try to play the next one, it wont start.

If i try to reInit the player, and the start playing again, it crashes.

private void loadvideo() {
    Uri uri = Uri.parse(VIDEO_LIBRARY_URL + currentVideo + ".mp4");
    sampleSource = new FrameworkSampleSource(this, uri, null, 2);

    // 1. Instantiate the player.
    // 2. Construct renderers.
    videoRenderer = new MediaCodecVideoTrackRenderer(sampleSource, MediaCodec.VIDEO_SCALING_MODE_SCALE_TO_FIT_WITH_CROPPING);
    audioRenderer = new MediaCodecAudioTrackRenderer(sampleSource);
    // 3. Inject the renderers through prepare.
    player.prepare(videoRenderer, audioRenderer);
    // 4. Pass the surface to the video renderer.
    surface = surfaceView.getHolder().getSurface();

    player.sendMessage(videoRenderer, MediaCodecVideoTrackRenderer.MSG_SET_SURFACE, surface);
    // 5. Start playback.
    player.setPlayWhenReady(true);
    player.addListener(new ExoPlayer.Listener() {
        @Override
        public void onPlayerStateChanged(boolean playWhenReady, int playbackState) {
            Log.d(TAG, "onPlayerStateChanged + " + playbackState);
            if (playbackState == ExoPlayer.STATE_ENDED) {
                currentVideo++;
                loadNextVideo();
            }
        }

        @Override
        public void onPlayWhenReadyCommitted() {

        }

        @Override
        public void onPlayerError(ExoPlaybackException error) {

        }
    });

}

What am i doing wrong? How can i play videos continuity?

Thanks.

Answer 1

You can reuse the ExoPlayer up until the point that you call release(), and then it should no longer be used.

To change the media that it is currently playing, you essentially need to perform the following steps:

// ...enable autoplay...
player.stop();
player.seekTo(0L);
player.prepare(renderers);

Creating the renderers is a little bit more involved, but that's the flow you should follow and the player should be able to play back to back videos.
