我有一个我正在尝试加载的 wvm 文件，但它总是在准备时因 IO 异常而失败。

如果我尝试在同一设备上的 VLC 播放器中运行相同的 url，它将正常播放。

这是我的媒体播放器代码

    mPlayer = MediaPlayer.create(context, Uri.parse(file_url));

    if(mPlayer != null){
        mPlayer.setSurface(s);
        mPlayer.setOnCompletionListener(this);
        mPlayer.setOnErrorListener(this);
        mPlayer.setOnInfoListener(this);
        mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);

        video_prepared = true;
        if(got_initial_media_hit) {
            OnEvent(PLAYER_EVENT.load);
        }
    }
    else {
        OnError(PLAYER_ERRORS.player_not_loaded, "");
    }

这是我得到的错误

如果我改用 VideoView，它就像一个魅力。有任何想法吗？

我遇到了有关此 Create 功能的几个问题。

第一个，Java 似乎必须知道文件的类型，所以你必须在文件路径的开头写上“file://”。看到这个答案。

然后，后来，我在我的文件路径后面加上了FilesDir.AbsolutePath，我在它们之间缺少了一个“/”。

所以这个错误实际上与 Create 函数有关，而不是之后发生的事情。所以看看你的第一行。祝你好运。
