嗨我想在Android中將我的視頻文件上傳到Web服務器。我跟着這個教程:如何在android中將視頻文件上傳到網絡服務器?

Uploading files to HTTP server using POST on Android.

不過。我在我的logcat中出現了這個錯誤。我也收到了來自服務器的消息。

按照此過程中,我要上傳的視頻文件爲wowza媒體服務器。我該如何解決這個問題。我怎樣才能繼續在wowza服務器?任何人都可以幫助我實現這個目標嗎? 在此先感謝。

它只是因爲視頻的大尺寸。 對大文件/視頻使用塊上傳方法。

以下是用於在服務器上發佈塊數據的示例代碼。

public void upload(String filename, byte[] image) { 
    // 1MB of chunk 
    byte[][] divideByte = divideArray(image, ((1024 * 1024)/2)); 
    int length = divideByte.length; 
    String token = "" + (int)System.currentTimeMillis(); 
    Log.i("System out", "divideByte:" + length); 
    Log.i("System out", "token:" + token); 

    for (int i = 0; i < length; i++) { 
     List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(); 

     String link = "<your link>"; 

     nameValuePairs.add(new BasicNameValuePair("filename", filename));// filename 
     HttpClient httpclient = new DefaultHttpClient(); 
     HttpPost httppost = new HttpPost(link); 
     Log.i("System out", "divideByte[" + i + "] length :" 
       + divideByte[i].length); 
     String img = Base64.encodeBytes(divideByte[i]); 
     nameValuePairs.add(new BasicNameValuePair("file64", img)); 

     nameValuePairs.add(new BasicNameValuePair("token", new String("" 
       + token))); 
     nameValuePairs.add(new BasicNameValuePair("chunksize", new String(""+ 
       divideByte[i].length))); 
     nameValuePairs.add(new BasicNameValuePair("chunkcount", new String(
       "" + length))); 
     nameValuePairs.add(new BasicNameValuePair("index", new String("" 
       + i))); 
     try { 
      httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 
      HttpResponse response = httpclient.execute(httppost); 
      HttpEntity httpEntity = response.getEntity(); 
      if (httpEntity != null) { 
       String res = EntityUtils.toString(httpEntity).toString(); 
       Log.i("System out", "response is :" + res);     
      } 
      httpEntity = null; 
      response = null; 
     } catch (Exception e) { 
      e.printStackTrace(); 
     }finally{ 
      httppost = null; 
      httpclient = null; 
     }   
    } 
} 

public static byte[][] divideArray(byte[] source, int chucksize) { 

    byte[][] ret = new byte[(int) Math.ceil(source.length 
      /(double) chucksize)][chucksize]; 

    Log.i("System out","ret: "+ret.length); 
    int start = 0; 

    for (int i = 0; i < ret.length; i++) { 
     if (start + chucksize > source.length) { 
      System.arraycopy(source, start, ret[i], 0, source.length 
        - start); 
     } else { 
      System.arraycopy(source, start, ret[i], 0, chucksize); 
     } 

     start += chucksize; 
    } 

    return ret; 
} 

,並在服務器端得到的所有數據塊索引明智和組成一個視頻文件。

希望對你有所幫助。

從byte []向服務器發送視頻可能會導致outOfMemoryError,因此最好從MultiPart發佈視頻。你可以從這個鏈接下載jar文件。 http://hc.apache.org/downloads.cgi。下載並將httpmime-4.2.jar添加到您的項目中。

public void uploadVideo(Context context, String videoPath) { 
     try { 
      HttpClient httpClient = new DefaultHttpClient(); 
      HttpPost postRequest = new HttpPost(context.getString(R.string.url_service_fbpost)); 
      MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE); 
      if(!videoPath.isEmpty()){ 

       FileBody filebodyVideo = new FileBody(new File(videoPath)); 
       reqEntity.addPart("uploaded", filebodyVideo); 
      } 
      postRequest.setEntity(reqEntity); 
      HttpResponse response = httpClient.execute(postRequest); 

      BufferedReader reader = new BufferedReader(new InputStreamReader(
        response.getEntity().getContent(), "UTF-8")); 
      String sResponse; 
      StringBuilder s = new StringBuilder(); 

      while ((sResponse = reader.readLine()) != null) { 
       s = s.append(sResponse); 
      } 

      Log.e("Response: ", s.toString()); 
      return true; 

     } catch (Exception e) { 
      Log.e(e.getClass().getName(), e.getMessage()); 
      return false; 
     } 
}
