设想一

  //开始录制
                _option.mp4_save_path = custom_path;
                _option.mp4_max_second = max_second;
                vector<Track::Ptr> mytracks = getTracks();
                auto src = MediaSource::find( DEFAULT_VHOST, "1", "adminstream");
             /*   if (src) {
                    vector<Track::Ptr> one =src->getTracks();
                    mytracks.emplace_back(one[0]);

                }*/
                _mp4 = makeRecorder(sender, getTracks(), type, _option);

          //开始执行命令

          Process process = builder.start();


          //如果你想获取到执行完后的信息，那么下面的代码也是需要的

          StringBuffer sbf = new StringBuffer();

          String line = null;

          BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));

          while ((line = br.readLine()) != null) {

              sbf.append(line);

              sbf.append(" ");

          }

          String resultInfo = sbf.toString();

          System.out.println(resultInfo);


      } catch (IOException e) {

          e.printStackTrace();

      }

    }
