好的,这有点令人沮丧,我已经搜索了Stack,但没有一个答案似乎有帮助。
我有一个Android应用程序,可以在屏幕上循环显示不同的内容。有一次,它播放视频,同一视频,从同一个地方加载。
在随机播放次数后,它决定停止播放视频文件并将错误抛出(-2147483648),这是一个未找到的通用文件/格式错误。
问题是在出现此错误之前,视频会多次正确播放。我已经尝试了许多替代方法来解决这个问题:
然而,经过多次播放后,它最终会拒绝播放视频。
一个可能或可能没有相关的变化是,当从文件描述符播放时,它会抛出一个媒体播放器准备Java I / O异常,我认为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。
以下是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?让我发疯了。

更新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且运行了12个多小时没有发生任何事故。所以,它看起来是一个平台错误,但仍然需要解决这个问题。
答案 0 :(得分:1)
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。
答案 1 :(得分:0)
我不确定但我认为这是由于某些缓存问题,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,文件损坏,文件错误,但您的情况似乎不同。
您可以使用reset并重试
public void reset()从:API Level 1
将MediaPlayer重置为未初始化状态。打电话给这个 方法,您必须通过设置数据再次初始化它 来源和调用prepare()。
答案 2 :(得分:0)
视频确实在下一次循环播放,所以我猜这是设备特有的。
