语法基础：std::ofstream 读取文件

视频点播数据接收，保存代码片段

  static std::ofstream ofstreamHanle;
  static bool bFirst = true;
  if (bFirst)
  {
    ofstreamHanle.open("F:/videoOutput.h264", std::ios::out | std::ios::binary);
    bFirst = false;
  }
  ofstreamHanle.write((char*)pucBuffer, dwBufSize);
  ofstreamHanle.flush();
