after tons and tons of googleing and reading I realized that UDP broadcasts can be done in a LAN but the server doesnt generate the stream the stream is generated by another eqipment(IP CAM)

Another idea of mine is the IP camera's stream is password protected so getting that stream and multicastting that stream to other clients is not possible because some how the clients will need to recognize a camera so its a must that the client's should access that IP so no point on multicasting !!

but another method is using the recorded stream. I can easily multicast a video which is available in my PC again another obstacle which is live video ! I cannot live multicast

Now I am thinking is it possible to read the stream while its being recorded ?

If can I can try to multicast that video stream which is in the memory ?

please advice !
