如何在 ExoPlayer.STATE_ENDED 后重新启动 Exoplayer 上的视频

Question

我在 Exoplayer 的基础上使用 DemoPlayer。我想 restart/replay 视频从某些用户操作开始 ExoPlayer.STATE_ENDED 已发送。

之后我尝试使用 seekTo(0) 和 mPlayer.setPlayWhenReady(true);，但它根本没有做任何事情。

Answer 1

我已经将库更新为 ExoPlayer r1.4.2 并且它完成了工作...

    mPlayer.seekTo(0);
    mPlayer.setPlayWhenReady(true); // replay from start

// 重启后暂停视频

    mPlayer.seekTo(0);
    mPlayer.setPlayWhenReady(false);

Answer 2

可以使用 LoopingMediaSource 无缝循环播放视频。以下示例无限期地循环 audio/video。也可以在创建 LoopingMediaSource 时指定有限循环次数。

MediaSource source = new ExtractorMediaSource(audioUri, ...);
// Loops the audio indefinitely.
LoopingMediaSource loopingSource = new LoopingMediaSource(source);

或添加一个监听器

playerExo.addListener(new ExoPlayer.Listener() {

            @Override
            public void onPlayerStateChanged(boolean playWhenReady, int playbackState) {

                switch(playbackState) {
                    case ExoPlayer.STATE_BUFFERING:
                        break;
                    case ExoPlayer.STATE_ENDED:
                        playerExo.seekTo(0);
                        break;
                    case ExoPlayer.STATE_IDLE:
                        break;
                    case ExoPlayer.STATE_PREPARING:
                        break;
                    case ExoPlayer.STATE_READY:
                        break;
                    default:
                        break;
                }
            }

            @Override
            public void onPlayWhenReadyCommitted() {

            }

            @Override
            public void onPlayerError(ExoPlaybackException error) {

            }
        });
        playerExo.seekTo(0);
        playerExo.setPlayWhenReady(true);//replay from start



/*  If you want to Pause audio/video and restart
 mPlayer.seekTo(0);
 mPlayer.setPlayWhenReady(false);*/

您可以检查 Exoplayer 最新版本是否是最新的：

这段代码对我有用

 @OnClick(R.id.image_button_play)
public void play(){
    Log.d(TAG, "play: clicked");
    //If video has finished then set Exoplayer to 0
    if (simpleExoPlayer.getPlaybackState() == Player.STATE_ENDED){
        simpleExoPlayer.seekTo(0);
    }
    simpleExoPlayer.setPlayWhenReady(true);
    playButton.setVisibility(View.INVISIBLE);
}
