我有一个带有 VideoView 的应用程序正在播放来自内部存储的 mp4 文件(我的包 files 目录)

在 一些 Samsung Epic Touch 4g (Galaxy SII) 设备上，显示的视频不是全黑屏幕。我的应用程序中的其他所有内容都正常运行和响应，因此设备根本不会“卡住”，它只是在屏幕上显示黑色而不是视频。

为了开始我的视频，我使用 onPreparedListener 回调来调用 start():

mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
    @Override
    public void onPrepared(MediaPlayer arg0) {
        mVideoView.start();
    }
});

然后我将视频设置为通过此调用播放:

//file is the reference to my video File object. 
//I am positive that it is correct
mVideoView.setVideoPath(file.getAbsolutePath());

我有一个这样的 onErrorListener 设置:

mVideoView.setOnErrorListener(new OnErrorListener(){
    @Override
    public boolean onError(MediaPlayer arg0, int arg1, int arg2) {  
        Log.i(myTag, "MP ERROR: "+ arg1 + " - " + arg2);
        /* I have also tried this here, no luck this way either
        mVideoView.setVideoPath(file.getAbsolutePath());
        return true;
        */
        return false;
    }       
});

仔细检查后，我意识到我的 onErrorListener 根本没有收到回调。

当屏幕上一片漆黑时，日志中一遍又一遍地充斥着这些消息:

V/PlayerDriver(2579): HandleInformationalEvent: PVMFInfoProcessingFailure
V/PlayerDriver(2579): HandleInformationalEvent: type=16 UNHANDLED
E/MFC_DEC_APP(2579): SsbSipMfcDecExe] IOCTL_MFC_DEC_EXE failed(ret : -2001)

和(有时下一行会与上述 4 行的垃圾邮件一起迭代。但其他时候，在上述 4 行的垃圾邮件多次迭代后，这两行会自己发送垃圾邮件。)

W/MediaPlayer(30537): info/warning (1, 16)
I/MediaPlayer(30537): Info (1,16)

我不认为这是我的视频 (AVC MP4) 的编码问题，因为完全相同的视频在 一些 Epic Touch 4g 设备(甚至一些在相同版本的操作系统上)上运行).我过去曾在此设备上使用过完全相同的视频，当设备升级到操作系统版本 2.3.6 时，这些问题开始出现。

谁能阐明我看到的 OMX/MFC 错误？或者有没有其他人遇到过 VideoView 只显示黑屏而不是视频的问题？最后，有没有其他方法可以让我开始准备/播放我的视频文件，而不会导致这些错误和黑屏？

编辑: 我在 this file 中找到那个警告 #16 是:

/*
Notification that a processing failure occurred (not fatal error)
*/
const PVMFStatus PVMFInfoProcessingFailure = 16;

这应该是一个非 fatal error 。我想它没有崩溃，所以它不是“致命的”，但无论发生什么，都会导致我的视​​频无法正常显示。

编辑 2:视频开始时，设备会记录更多日志。这些都出现在上面的垃圾邮件之前:

最佳答案

我曾经遇到过类似的问题，当我的回调出现错误时，我通过重新加载 Activity 来解决这个问题。起初它有效，但后来它一直失败，这导致 Activity 的无限重启循环。然后我决定在这种情况下放一张图片而不是视频(这真的没那么重要)。

我猜这值得一试...如果您没有收到任何对您的 onErrorListener 的回调，只需在 Activity 运行 5 秒后运行它，以测试它是否解决了您的问题。

这是我为重新加载 Activity 而编写的代码:

public void reload(String boolExtra) {
    Intent intent = getIntent();
    overridePendingTransition(0, 0);
    intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    finish();

    overridePendingTransition(0, 0);
    startActivity(intent);
}

我可以建议的另一种方法 - 使用编解码器。我知道它在其他设备上运行良好，但您永远无法知道此特定 Android 版本附带的此特定设备的编解码器是否存在错误。也尝试更改其尺寸。

祝你好运:)
