Display live video feed from multiple IP Camera , C++ MFC

edit

I want to display video feed from Multiple IP camera on my network, Currently I am able to display the video feed in picture control in MFC, but the video feed is distrubed when other IP Camera is added. I have coded a timer event where after every 10 milliseconds the QueryFrame for respected camera is called. But the problem is when I add other camera for streaming the video. Either the first IP Camera will disconnect or it will display Frames in slow motion.
