 * \brief The CMultimediaRecordThread class
 * \details Must use pointer. eg:
 * - New object:
 *  \code
 *  CMultimediaRecordThread* pThread = new CMultimediaRecordThread(m_pPara);
 *  \endcode
 * - Start thread:
 *  \code
 *  if(pThread)
 *      pThread->start();
 *  \endcode
 * - Stop thread.
 *  \code
 *  pThread->slotQuit();
 *  \endcode
 *
 * \note
 * - It automatically releases memory when exiting.
 * - To stop a thread, you must use slotQuit(), and cannot use quit().
