read video stream from IP address assign to Avtech 4 channel MPEG4 DVR using C, C++, MFC

[C++ Programming]

Hi,

Can anybody please help me to read a video stream from an IP address assigned to Avtech 4 channel MPEG4 DVR.

The DVR is connected with 4 webcams.
DVR stores video stream in a raw format on connected Hard Disk Drive.
DVR is also connected to a ethernet switch and it throws video streams on assigned IP address on 80 port.
i want to read that video stream from DVR IP address and port 80 using C, C++, or MFC.

Thanks & Regards,
Kunal.
