APlayerCaller.dll 是把 ActiveX 调用转为普通 DLL调用的方式的工具，论坛有开源的代码，具体使用方法：
创建：返回 APlayer LONG_PTR 类型的句柄
LONG_PTR APlayer_Create(LONG_PTR hParentWnd,
LONG x,
LONG y,
LONG nWidth,
LONG nHeight,
LONG OnMessage,
LONG OnStateChanged,
LONG OnOpenSuccess,
LONG OnSeekCompleted,
LONG OnBuffer,
LONG OnVideoSizeChanged,
LONG OnDownloadCodec,
LONG OnEvent);
销毁：传入 APlayer 句柄
BOOL APlayer_Destroy(LONG_PTR aplayer);
调用 APlayer 方法（顾名思义）：
BOOL APlayer_OpenW(LONG_PTR aplayer, WCHAR* pszUrl)
BOOL APlayer_OpenA(LONG_PTR aplayer, char* pszUrl)
BOOL APlayer_Close(LONG_PTR aplayer)
BOOL APlayer_Play(LONG_PTR aplayer)
BOOL APlayer_Pause(LONG_PTR aplayer)
char* APlayer_GetVersion(LONG_PTR aplayer)
BOOL APlayer_SetCustomLogo(LONG_PTR aplayer,LONG nLogo)
LONG APlayer_GetState(LONG_PTR aplayer)
LONG APlayer_GetDuration(LONG_PTR aplayer)
LONG APlayer_GetPosition(LONG_PTR aplayer)
LONG APlayer_SetPosition(LONG_PTR aplayer, LONG nPosition)
LONG APlayer_GetVideoWidth(LONG_PTR aplayer)
LONG APlayer_GetVideoHeight(LONG_PTR aplayer)
LONG APlayer_GetVolume(LONG_PTR aplayer)
LONG APlayer_SetVolume(LONG_PTR aplayer, LONG nVolume)
LONG APlayer_IsSeeking(LONG_PTR aplayer)
LONG APlayer_GetBufferProgress(LONG_PTR aplayer)
char* APlayer_GetConfigA(LONG_PTR aplayer, LONG nConfigId)
WCHAR* APlayer_GetConfigW(LONG_PTR aplayer, LONG nConfigId)
LONG APlayer_SetConfigW(LONG_PTR aplayer, LONG nConfigId, WCHAR* strValue)
LONG APlayer_SetConfigA(LONG_PTR aplayer, LONG nConfigId, char* strValue)
LONG_PTR APlayer_GetWindow(LONG_PTR aplayer)
BOOL APlayerCaller_SetSize(LONG_PTR aplayer, LONG x, LONG y, LONG nWidth, LONG nHeight);
