传递输入流视频查看

Question

我有我需要把它作为以视频观看输入流：

但它说的OutOfMemoryError

这里是我的代码：

//to convert input stream to string 
public static String convertStreamToString(InputStream is) throws Exception { 
     BufferedReader reader = new BufferedReader(new InputStreamReader(is)); 
     StringBuilder sb = new StringBuilder(); 
     String line = null; 

     while ((line = reader.readLine()) != null) { 
      sb.append(line); 
     } 

     is.close(); 

     return sb.toString(); 
    } 

//passing that string to video view 
String total = convertStreamToString(inputStream); 
Uri uri = Uri.parse(total); 
videoHolder.setVideoURI(uri); 

如何这是什么成绩？

这里是堆栈跟踪

好，我已经解决了自己，但它的视频文件前3到4秒延时启动

希望它可以帮助一些：

public static String getDataSource(String path) throws IOException { 
     if (!URLUtil.isNetworkUrl(path)) { 
      return path; 
     } else { 
      URL url = new URL(path); 
      URLConnection cn = url.openConnection(); 
      cn.connect(); 
      InputStream stream = cn.getInputStream(); 
      if (stream == null) 
       throw new RuntimeException("stream is null"); 
      File temp = File.createTempFile("mediaplayertmp", "dat"); 
      temp.deleteOnExit(); 
      String tempPath = temp.getAbsolutePath(); 
      FileOutputStream out = new FileOutputStream(temp); 
      byte buf[] = new byte[128]; 
      do { 
       int numread = stream.read(buf); 
       if (numread <= 0) 
        break; 
       out.write(buf, 0, numread); 
      } while (true); 
      try { 
       stream.close(); 
       out.close(); 
      } catch (IOException ex) { 
       // Log.e(TAG, "error: " + ex.getMessage(), ex); 
      } 
      return tempPath; 
     } 
    }
