Android视频在多次播放错误1,2147483648后停止播放-Java 学习之路

好吧，这有点令人沮丧，我已经搜索过Stack，但没有一个答案似乎有所帮助 .

我有一个Android应用程序，它循环屏幕上的不同内容 . 有一次，它播放视频，同一视频，从同一个地方加载 .

在随机播放数量之后，它决定停止播放视频文件并向上抛出错误（-2147483648），这是一个未找到的通用文件/格式错误 .

问题是视频在此错误出现之前多次正确播放 . 我已经尝试了许多替代方法来解决这个问题：

播放文件的VideoView（开头）
从媒体读取MediaPlayer SurfaceView组合
MediaPlayer从文件描述符读取SurfaceView
强制世界可读的权限
将文件复制到临时文件并播放
手动释放VideoView和MediaPlayer选项的媒体播放器
每次播放后
运行手动垃圾回收

然而，经过多次播放后，它最终会拒绝播放视频 .

可能会或可能不相关的一个变化是，当从文件描述符播放时，它会抛出媒体播放器准备Java I / O异常，我相信这可能与某些锁定发生在文件上有关 .

解决此问题的唯一方法是重启设备 . 重新启动应用程序无法修复它，它会立即拒绝播放该文件 .

这是VideoView播放代码：

// from main activity
File afile = new File(btvapp.fileroot,btvapp.getDailyVideo().get("FILENAME"));        
afile.setReadable(true, false);
theVideo = (VideoView) findViewById(R.id.videoViewer);
theVideo.requestFocus();
theVideo.setVideoPath(afile.getPath());
theVideo.setOnPreparedListener(this);
theVideo.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
    @Override
    public void onCompletion(MediaPlayer mp) {
        // TODO Auto-generated method stub
        //mp.release();
        theVideo.stopPlayback();
        mp.release();
            finish();

    }
} );
theVideo.setOnErrorListener(new MediaPlayer.OnErrorListener() {
    @Override
    public boolean onError(MediaPlayer mp, int what, int extra) {
            finish();
            return false;
        }
    });

// play on prepared function
@Override
  public void onPrepared(MediaPlayer mp) {
  // TODO Auto-generated method stub
  mp.start();
}

表面视图几乎完全使用Android SDK媒体播放示例，但我认为不值得粘贴代码，因为无论您使用的是mediaplayer surfaceview方法还是VideoView播放方法，都会发生错误 .

思考？快把我逼疯了 .

UPDATE 2: 我已经在其他2个Android设备（一个ICS，一个姜饼）上测试了代码，并且烦人地在它们上运行正常并运行了12个多小时而没有发生任何事故 . 所以，它看起来是一个平台错误，但仍然需要解决这个问题 .

我几乎肯定这是你正在使用的基于Amlogic的设备的问题（显然是由于logcat中的“amplayer”和“AmlogicPlayer”） . 我们正在测试的基于Amlogic AML8726的设备存在很多问题 . 如果可能，请尝试升级固件 .

我不确定但我认为这是由于一些缓存问题，因为它播放x次然后停止播放 . 文件无法访问可能是由于多种原因：权限，损坏的文件，错误的文件，但您似乎是一个不同的情况 .

你能用reset然后再试一次

public void reset（）从以下版本开始：API Level 1将MediaPlayer重置为未初始化状态 . 调用此方法后，您必须通过设置数据源并调用prepare（）再次初始化它 .

好吧，我从来没有把这个解决到我最终的满足感，特别是因为它特别适用于设备 . 最后我刚刚添加了异常处理，因此在播放视频失败时不会崩溃，只是跳过它并在下次再试一次 .

视频确实在下一次循环播放，所以我猜它是特定于设备的东西 .
