我正在尝试在 android 中使用 Brightcove Exoplayer 播放一个又一个视频。我能够在第一个视频的结尾捕捉到事件类型“已完成”，然后我正在尝试播放下一个视频。但它卡在第一个视频的末尾。第二个视频没有播放。我得到一个 NullPointerException。我究竟做错了什么？这是我的代码：

public class MainActivity extends BrightcovePlayer {

    private final String TAG = this.getClass().getSimpleName();

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        setContentView(R.layout.activity_main);
        brightcoveVideoView = (BrightcoveExoPlayerVideoView) findViewById(R.id.brightcove_video_view);
        super.onCreate(savedInstanceState);

        EventEmitter eventEmitter = brightcoveVideoView.getEventEmitter();
        final Catalog catalog = new Catalog(eventEmitter, "accountID", "policy");

        catalog.findVideoByID("videoID1", new VideoListener() {

            @Override
            public void onVideo(Video video) {
                Log.v(TAG, "onVideo: video = " + video);
                brightcoveVideoView.add(video);
                brightcoveVideoView.start();
            }


        });

        eventEmitter.on("completed", new EventListener() {
            @Override
            public void processEvent(Event event) {

               catalog.findVideoByID("videoID2", new VideoListener() {

                    @Override
                    public void onVideo(Video video) {
                        brightcoveVideoView.clear();
                        brightcoveVideoView.stopPlayback();
                        brightcoveVideoView.seekTo(0);
                        Log.v(TAG, "onVideo: video = " + video);
                        brightcoveVideoView.add(video);
                        brightcoveVideoView.start();
                    }


                });
            }
        });


        // Log whether or not instance state in non-null.
        if (savedInstanceState != null) {
            Log.v(TAG, "Restoring saved position");
        } else {
            Log.v(TAG, "No saved state");
        }
    }
}

而不是使用

eventEmitter.on("completed", new EventListener() {

在 BrightcoveExoPlayerVideoView 对象上使用 OnCompletionListener。这是一个从播放列表中依次播放视频的示例。首先，它使用 com.brightcove.player.media.Catalog 通过 id 获取播放列表，然后在上一个视频完成时使用 com.brightcove.player.edge.Catalog 播放下一个视频

import android.media.MediaPlayer;
import android.os.Bundle;
import android.util.Log;
import com.brightcove.player.edge.VideoListener;
import com.brightcove.player.event.EventEmitter;
import com.brightcove.player.media.PlaylistListener;
import com.brightcove.player.model.Playlist;
import com.brightcove.player.model.Video;
import com.brightcove.player.view.BrightcoveExoPlayerVideoView;
import com.brightcove.player.view.BrightcovePlayer;
import java.util.List;
public class MainActivity extends BrightcovePlayer {
    private final String TAG = this.getClass().getSimpleName();
    private List<Video> videos;
    private int videoIndex = 0;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        setContentView(R.layout.activity_main);
        brightcoveVideoView = (BrightcoveExoPlayerVideoView) findViewById(R.id.brightcove_video_view);
        super.onCreate(savedInstanceState);

        //Get the playlist
        com.brightcove.player.media.Catalog mediaCatalog = new com.brightcove.player.media.Catalog(getString(R.string.brightcove_token));
        mediaCatalog.findPlaylistByID(getString(R.string.playListId), new PlaylistListener() {
            @Override
            public void onPlaylist(Playlist playlist) {
                videos = playlist.getVideos();
                if (videos != null && videos.size() > 0)
                    playVideo(videos.get(videoIndex));

            }

            @Override
            public void onError(String s) {
                Log.d(TAG, "onCreate() findPlaylistByID() onError()" + s);
            }
        });

    }

    private void playVideo(Video video) {
        if (video == null) return;

        //Play the video
        EventEmitter eventEmitter = brightcoveVideoView.getEventEmitter();
        com.brightcove.player.edge.Catalog catalog = new com.brightcove.player.edge.Catalog(eventEmitter, getString(R.string.account), getString(R.string.policy));
        catalog.findVideoByID(video.getId(), new VideoListener() {
            @Override
            public void onVideo(Video video) {
                brightcoveVideoView.add(video);
                brightcoveVideoView.start();
            }
        });

        //Play the next video in the list when the current one is completed
        brightcoveVideoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
            @Override
            public void onCompletion(MediaPlayer mp) {
                if (videoIndex == videos.size()) {
                    videoIndex = 0;
                } else {
                    videoIndex++;
                }
                playVideo(videos.get(videoIndex));
            }
        });
    }

}

activty_main.xml

<merge xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity" >

    <com.brightcove.player.view.BrightcoveExoPlayerVideoView
        android:id="@+id/brightcove_video_view"
        android:layout_width="match_parent"
        android:layout_height="280dp"
        android:layout_gravity="center_horizontal|top"/>

</merge>

对于 value 文件夹中的 string.xml，填写您的凭据、令牌、播放列表 ID 等。

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <!-- Application name -->
    <string name="app_name">ExoPlayer Sample App</string>

    <!-- A sample Brightcove Edge Account ID -->
    <string name="account"></string>

    <!-- A sample Brightcove Edge Policy Key -->
    <string name="policy"></string>

    <string name="playListId"></string>

    <string name="brightcove_token"></string>

</resources>

调用 brightcove 视频视图的 clear 方法后，无需调用 stopPlayback 和 seek。更好的方法是清除、添加并从新的视频对象开始

brightcoveVideoView.clear();
brightcoveVideoView.add(video);
brightcoveVideoView.start();

有点晚了，但考虑没有答案......

弄乱视频列表（即在 BC 播放器中动态添加/删除Video对象 - 任何从BaseVideoView派生的对象）会很快让你脱轨，并且会让你 1）哭泣或 2）对无辜的旁观者尖叫 :)

我有自己的理论，但这与问题无关。

我们通过动态停止/销毁已完成的播放器，然后为下一个要播放的视频添加一个全新的播放器来解决问题。

意思是：

  • 将您的视频列表保存在您的活动/片段/视图容器中
  • 当视频结束时，确保您清除资源，然后从视图列表中物理删除播放器视图
  • 显示预加载器或一些不错的动画
  • 添加或膨胀另一个 exo 播放器实例（使用 Runnable 以避免在准备时预加载器冻结），然后加载下一个视频
  • 当为视频发送事件准备好播放时隐藏预加载器并播放视频

这很有效，视图交换几乎是立即的 - 几乎不引人注意。
