媒体存储实现类

        媒体存储实现类派生于媒体存储接口类，也派生于线程基类。媒体存储实现类的头文件如下：

#include <HP_Base/HP_Mutex.h>
#include <HP_Base/HP_FifoMemPool.h>

#include "HP_MediaStorage.h"
#include "MediaDisk.h"

{
public:
    static void Open();
    static CMediaStorage *&Singleton();
    static void Close();

    virtual int SetRecordDuration(unsigned int uiDurationMinutes);

    virtual int WriteVideoFrame(unsigned int uiCameraChannel, unsigned char *pFrame, unsigned int uiFrameLen,

        const TMppRecordAudioFrameInfo &info);
