ExoPlayer - 接连打10文件之一 [英] ExoPlayer - play 10 files one after another

问题描述

我有10个视频，我需要踢球，当一个人完成，下一个开始播放。

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

我使用谷歌的ExoPlayer ，我用这个例子在<一个href="https://github.com/google/ExoPlayer/tree/master/demo/src/main/java/com/google/android/exoplayer/demo"相对=nofollow>样本@ GitHub上。 我可以玩1个视频，但如果我尝试播放下一个，它不会启动。

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.

如果我尝试重新初始化播放器，并重新开始播放，它崩溃。

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) {

        }
    });

}

我究竟做错了什么？ 我怎么能播放视频的连续性？

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

感谢。

推荐答案

您可以重复使用ExoPlayer，直到你调用发布（）的点，然后它不应再使用。

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

要改变媒体认为这是当前正在播放，您基本上需要执行以下步骤：

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);

创建渲染器是更复杂一点，但是这是你应该遵循的流程和玩家应该能够打背靠背的视频。

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.
