How to grab a video stream from an IP-address?

Hi

Does anyone know how I can grab a video stream from an IP-address? There's a video web server for live image transmission in the Internet. Data transfer is accomplished via TCP/IP. The web cam that I am using is integrated into a network with fixed IP address. The streaming software is already there, so I have to go to this IP-address to see the live video stream.

How can I grab this video stream from an IP-address with an application programmed in C++ ??

Please help!

Thanks!

1. Use Winsock API to receive data from a TCP port (that's the easy part).
2. Discover every detail about the streaming protocol & implement it or find
an existing library.
3. Discover every detail about the compression that's used & implement it or
find an existing library.
4. Use Direct-X or Win32 GDI to display frames of video on the screen.

In short, how to access TCP is the least of your worries.

Thank you so much for answering!

The IP-videoserver use the "server push" - technology to stream images over http, using TCP/IP only. For the IE a Java-Applet or ActiveX-module is used to make the streaming visible

So what do I do next after the socket part?

Which classes and how to connect this to the image processing application?

Thank yo
