從服務器下載後無法播放視頻

我的媒體錄像機正在錄製視頻後錄製視頻，我正在預覽我的視頻（很好）。現在已將此視頻上傳到本地http服務器。並最終從服務器獲取此視頻播放，但它顯示無法播放視頻。從服務器下載後無法播放視頻

任何建議，其中實際的錯誤是... thanx的幫助。

MediaRecorder

this.mediaRecorder = new MediaRecorder(); 
this.mediaRecorder.setCamera(this.camera); 
camera.unlock(); 
this.mediaRecorder.setCamera(camera); 
this.mediaRecorder.setOrientationHint(90); 
this.mediaRecorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT); 
this.mediaRecorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT); 
CamcorderProfile camcorderProfile_HQ = CamcorderProfile.get(CamcorderProfile.QUALITY_480P); 
this.mediaRecorder.setProfile(camcorderProfile_HQ); 
this.mediaRecorder.setOutputFile(this.initFile().getAbsolutePath()); 
this.mediaRecorder.setMaxDuration(60000); // Set max duration 60 sec. 
this.mediaRecorder.setMaxFileSize(5000000); 


this.mediaRecorder.setPreviewDisplay(this.cameraPreview.getHolder().getSurface()); 


    try { 
    this.mediaRecorder.prepare(); 
    // start the actual recording 
    // throws IllegalStateException if not prepared 
    this.mediaRecorder.start(); 
    Toast.makeText(this, R.string.recording, Toast.LENGTH_SHORT).show(); 
    // enable the stop button by indicating that we are recording 
    this.toggleButtons(true); 
} catch (Exception e) { 
    Log.wtf(TAG, "Failed to prepare MediaRecorder", e); 
    Toast.makeText(this, R.string.cannot_record, Toast.LENGTH_SHORT).show(); 
    this.releaseMediaRecorder(); 
}

視頻視圖

Uri uri = Uri.parse("/data/data/com.example.mediarecorder/files/"+ messageList.get(position)); //do not add any extension 

      video.setVideoURI(uri); 
      video.requestFocus(); 
      setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 
      video.setKeepScreenOn(true); 
      System.out.println(uri + " "+ uri.getEncodedAuthority()+ " "+ uri.decode(data_type) + " "+ uri.getUserInfo() + " "+ uri.describeContents()); 
      video.start();

無法從內部存儲通過videoview播放視頻，因爲文件沒有世界可讀權限。您必須使用surfaceView和媒體播放器類創建自定義視頻播放器。然後，你必須創建你需要發揮並傳遞到mediaPlayer.setDataSource（）文件的文件描述符：

FileInputStream inputStream = new FileInputStream(videoPath); 
//assume videoPath = getFilesDir().getAbsolutePath()) + File.separator + "Video.mp4" 
mp.setDataSource(inputStream.getFD()); 
     mp.prepareAsync(); 
     try { 
      mp.setOnPreparedListener(new OnPreparedListener() { 

       @Override 
       public void onPrepared(MediaPlayer mplayer) { 
        if (mp != null) { 
         mp.start(); 
        } 
       } 
      });

其實我忘了提，我上傳視頻到http服務器（filezila）和我後我正在解析uri。它是在如Nexus 5更高版本設備的但不是在其他設備，諸如karbon和星系標籤運行。 @Sunny –
