Android MediaPlayer 流媒体错误 : 100: MEDIA_ERROR_SERVER_DIED

Question

我开发了一个应用程序，它利用了 native Android 的 MediaPlayer。我类使用媒体播放器的源代码如下。

问题是只有在某些设备上播放几毫秒后(我只能听到声音，屏幕仍然是黑的)我不断收到 error(100,0)，根据 documentation说

public static final int MEDIA_ERROR_SERVER_DIED

Media server died. In this case, the application must release the MediaPlayer object and instantiate a new one.

在论坛上，我发现每次获得它时我都需要重置播放器...但是我在很短的时间内获得它然后它就永远消失了。由于播放无用，我无法每秒重置播放器。我不明白为什么有些设备有这个问题而其他设备没有。我知道的是 Android OS > 4.0。

当然，首先调用 init()，然后调用 showVideo()。然后调用代码为 100 的最后一个 onError。使流连续运行而不中断的潜在解决方案是什么？

public class NativePlayer extends Player implements OnBufferingUpdateListener,
        OnCompletionListener, OnErrorListener, OnInfoListener {

    private VideoView videoview;
    private PlayerListener listener;
    private MainActivity context;

    private final Logger logger = LoggerFactory.getLogger(NativePlayer.class);

    @Override
    public void init(MainActivity activity) {
        this.videoview = (VideoView) activity.findViewById(R.id.video);
        context = activity;
    }

    @Override
    public void showVideo(final String url, final PlayerListener _listener) {
        listener = _listener;
        videoview.setVisibility(View.VISIBLE);
        try {
            Uri video = Uri.parse(url);
            videoview.setVideoURI(video);
        } catch (Exception e) {
            logger.error("Error playing video", e);
            listener.onVideoError();
            return;
        }

        videoview.setOnCompletionListener(this);
        videoview.setOnErrorListener(this);
        videoview.requestFocus();

        videoview.setOnPreparedListener(new OnPreparedListener() {
            public void onPrepared(MediaPlayer mp) {
                videoview.start();
                if (listener != null) {
                    listener.onVideoStarted();
                }
            }
        });
    }

    @Override
    public void onStop() {
        stop();
    }

    private void stop() {
        if (videoview == null) {
            return;
        }
        if (videoview.isPlaying()) {
            videoview.stopPlayback();
        }
    }

    @Override
    public void onDestroy() {
    }

    @Override
    public void onCompletion(MediaPlayer mp) {
        stop();
    }

    @Override
    public boolean onError(MediaPlayer mp, int what, int extra) {
        if (listener != null) {
            listener.onVideoError();
        }
        return false;
    }

    @Override
    public boolean onInfo(MediaPlayer mp, int what, int extra) {
        if (listener != null) {
            listener.onInfo(what, extra);
        }
        return false;
    }

    @Override
    public void onBufferingUpdate(MediaPlayer mp, int percent) {
        if (listener != null) {
            listener.onBufferingUpdate(percent);
        }
    }
}

我遇到了同样的问题(错误 100、媒体播放器死机等)。我通过使用 .stopPlayback() 解决了它，并再次开始播放。下面是我的部分代码:

private void startWatchVideo(final string video_link) {
        videoViewVA.setMediaController(new MediaController(this));
        videoViewVA.setVideoURI(Uri.parse(video_link));
        videoViewVA.requestFocus();
        videoViewVA.setOnPreparedListener(new OnPreparedListener() {
            public void onPrepared(MediaPlayer media) {
                media.start();
            }
        });

        videoViewVA.setOnErrorListener(new OnErrorListener() {
            @Override
            public boolean onError(MediaPlayer media, int what, int extra) {
                if (what == 100)
                {
                    videoViewVA.stopPlayback();
                    startWatchVideo(video_link);
                }
                return true;
            }
        });
    }

在实践中，视频似乎只是变慢了
