Question

我正在使用录制视频和播放缓冲视频作为主要功能的应用程序。

当我在 Android 中录制视频时，保存在SERVER和另一个屏幕上我在VIDEO的服务器上获得了一个URL，该URL用于在MEDIA PLAYER的缓冲区中播放。

问题是，当从这个应用的iPhone版本录制和上传的视频无法在Android应用中播放时。缓冲后我得到了以下错误。

02-20 14:13:18.729: E/MediaPlayer(19417): error (1, -2147483648)

在Android设备中创建的视频，在同一台服务器上传，可轻松缓存并在Android设备中播放。

以下是从我的iPhone创建的视频的网址：

 https://s3.amazonaws.com/WeddingApp/Weddingimage/1642_Video.MP4

我正在使用以下代码：

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setVolumeControlStream(AudioManager.STREAM_MUSIC);
        setContentView(R.layout.video_view);
        String videoUrl = this.getIntent().getStringExtra("VIDEO_URL");

        initControls();
        playVideo(videoUrl);
    }
    /**
     * initControls
     */
    private void initControls(){
        try{
            volumeSeekbar = (SeekBar)findViewById(R.id.sbarvolume);
            audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
            volumeSeekbar.setMax(audioManager
                    .getStreamMaxVolume(AudioManager.STREAM_MUSIC));
            volumeSeekbar.setProgress(audioManager
                    .getStreamVolume(AudioManager.STREAM_MUSIC));   


            volumeSeekbar.setOnSeekBarChangeListener(new OnSeekBarChangeListener(){
                @Override
                public void onStopTrackingTouch(SeekBar arg0) 
                {
                }
                @Override
                public void onStartTrackingTouch(SeekBar arg0) 
                {
                }
                @Override
                public void onProgressChanged(SeekBar arg0, int progress, boolean arg2) 
                {
                    audioManager.setStreamVolume(AudioManager.STREAM_MUSIC,
                            progress, 0);
                }
            });
        }
        catch (Exception e) 
        {
            e.printStackTrace();
        }
    }
    /**
     * playVideo
     * @param videoUrl 
     */
    public void playVideo(String videoUrl){
        videoView = (VideoView) findViewById(R.id.videoView);
        getWindow().clearFlags(WindowManager
                .LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);

        mc = new MediaController(this);
        videoView.setMediaController(mc);
        videoView.requestFocus();
        videoView.setVideoURI(Uri.parse(videoUrl));
        mc.show();
        videoView.start();

        videoView.setOnTouchListener(this);
        videoView.setOnClickListener(this);

        videoView.setOnCompletionListener(new OnCompletionListener() {
            @Override
            public void onCompletion(MediaPlayer mp) {
                VideoActivity.this.finish();
            }
        });
    }

请建议我。
