Hikvision Player SDK usage

==========================

#01 load PlayCtrl.dll

#02 call PlayM4_GetPort()

#03 call PlayM4_SetFileRefCallBack()

#04 call PlayM4_OpenFile()

#05 waits for the callback to be called, so we know the file is indexed

#06 call PlayM4_GetFileTime()

#07 call PlayM4_GetFileTotalFrames()

#08 call PlayM4_GetPictureSize()

#09 call PlayM4_Play(port, 0)

#10 PlayM4_SetCurrentFrameNum(port, 0)

#11 PlayM4_Pause(port, 1)

The above calling sequence seems to always work succesfully (no error codes reported).

Now the problem is when we do:

PlayM4_SetCurrentFrameNum(port, frame)

real_fram = PlayM4_GetCurrentFrameNum(port)

Now in some cases real_frame != frame
