Android 获取'MediaPlayer﹕；错误（1，-2147483648）`在从sd卡创建后立即尝试播放视频文件时

我已经从同样的问题中读到了很多答案，比如

我现在正在制作带有录制视频功能的

定制相机

我可以
拍摄照片，然后正确查看照片

但录制视频时出现
问题，然后立即查看视频

我想在录制视频后立即通过参数
文件路径
播放视频，而不是下次打开应用程序

我已经试过了：

1-扫描安卓系统已识别的新文件的媒体

2-试试
放固定的文件路径，就行了
，可以播放了<代码>“/mnt/sdcard/Pictures/Enterprise/VID_20150327_143003.mp4”
。但这不是我想要的

知道如何在录制视频后立即通过参数
文件路径
播放视频的人

请告诉我

谢谢

p/s:


我的案例是在成功录制视频后直接从sd卡播放视频，而不是从服务器流式播放视频

安卓4.1-索尼Xperia U

只有我的应用程序无法在成功录制视频后立即播放视频。如果使用默认媒体播放器应用程序（另一个应用程序）播放视频正常

另一件事，请注意，如果使用固定的文件路径可以播放现有的视频

下面是代码扫描介质，以查看创建后的新文件

这里的代码设置录制视频

private void showVideoOnUI() {
    Log.i("", "FILE_PATH " + FILE_PATH);

    // THIS LINE SHOW THE VIDEO TOTALLY CAN BE PLAYED
    //        mVvVideo.setVideoPath("/mnt/sdcard/Pictures/Enterprise/VID_20150327_143003.mp4");

    mVvVideo.setVideoPath(FILE_PATH);
    //        mVvVideo.setVideoURI(Uri.parse(FILE_PATH));

    // set play video view dialog details photo
    MediaController mMc = new MediaController(getActivity());
    mMc.setAnchorView(mVvVideo);
    mMc.setMediaPlayer(mVvVideo);

    mVvVideo.requestFocus();
    mVvVideo.setBackgroundColor(Color.WHITE);
    mVvVideo.setMediaController(mMc);
    mVvVideo.setZOrderOnTop(true);
    mVvVideo.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (mVvVideo.isPlaying()) {
                mVvVideo.pause();

                // Show full-screen button again
                mVvVideo.setVisibility(View.VISIBLE);
            } else {
                mVvVideo.start();
            }

            return false;
        }
    });

    if (!mVvVideo.isPlaying())
        mVvVideo.start();
}

private boolean prepareVideoRecorder(int mode){
    // Should release before use new Preview for Recording Video mode
    CustomCamera.releaseCamera();

    // Initialize camera
    CustomCamera.mCamera = CustomCamera.getCameraInstance(mode);

    // Set orientation display
    CustomCamera.setCameraDisplayOrientation(getActivity(), mode);

    // Should release before use new Preview for Recording Video mode
    CustomCamera.releaseMediaRecorder();

    CustomCamera.mMediaRecorder = new MediaRecorder();

    // Step 1: Unlock and set camera to MediaRecorder
    CustomCamera.mCamera.unlock();
    CustomCamera.mMediaRecorder.setCamera(CustomCamera.mCamera);

    // Step 2: Set sources
    CustomCamera.mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
    CustomCamera.mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);

    // todo Step 3: Set a CamcorderProfile (requires API Level 8 or higher)
    CustomCamera.mMediaRecorder.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_LOW));
    //        CustomCamera.mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);

    //        CustomCamera.mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);
    //        CustomCamera.mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);

    // Step 4: Set output file
    CustomCamera.mMediaRecorder.setOutputFile(getOutputMediaFile(MediaType.VIDEO).toString());

    // Step 5: Set the preview output
    CustomCamera.mMediaRecorder.setPreviewDisplay(mCameraPreview.getHolder().getSurface());

    // Step 6: Prepare configured MediaRecorder
    try {
        CustomCamera.mMediaRecorder.prepare();
    } catch (IllegalStateException e) {
        e.printStackTrace();
        CustomCamera.releaseMediaRecorder();
        return false;
    } catch (IOException e) {
        e.printStackTrace();
        CustomCamera.releaseMediaRecorder();
        return false;
    }
    return true;
}

我终于认识到自己的错误。对不起。我需要编辑代码如下

// Step 3: Set a CamcorderProfile (requires API Level 8 or higher)
    CustomCamera.mMediaRecorder.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH));

    // Step 4: Set output file
    RECORDED_FILE_PATH = getOutputMediaFile(MediaType.VIDEO).toString();
    CustomCamera.mMediaRecorder.setOutputFile(RECORDED_FILE_PATH);

及

好了，我现在有办法了

这是我的错。我调用了两次
getOutputMediaFile（）
方法，因此它创建了两个文件：


1文件通过使用流传输数据。[此文件未读取我的应用程序]

1文件没有数据[此文件我的应用程序已读取]


因此，
video不能播放
对话框出现，我也得到了这个错误
MediaPlayer﹕ 错误（1，-2147483648）

p/s：我希望我能解释一下为什么会出现这种
UNKNOWN\u错误

很抱歉

谢谢。
可能是@maven的副本我已经看过答案了。这看起来像是建议，建议表明，相关的东西作为编码器。。。实际上这不是解决办法，不是吗？你怎么认为？或者你明白答案表明什么？请告诉我。谢谢。没有直接的解决方案，您必须验证录制的视频格式并制作它。
“录制的视频格式并使其与编码器兼容”
-实际上默认的媒体播放器可以播放我录制的视频。那么这还不够？正如我在问题中所说，我的应用程序只有在成功录制视频后才能立即播放。如果我通过了
固定文件路径
值，它完全可以播放。错了吗？
