1. Open VLC Media Player.

2. Click File | Open Network Stream...
3. There are four different types of streams that VLC can play:

1. UDP/RTP - This is a unicast stream, meaning that there is another computer sending a stream directly to your computer. You need to set the correct UDP port (this is set by whoever is sending the stream to you; the default is 1234 for streams sent by VLC)
2. UDP/RTP Multicast - This is the multicast version of the previous, meaning that there is another computer sending out streams to many computers. You need to set the correct address and UDP port (once again, found through whoever is setting up the stream)
3. HTTP/FTP/MMS - This is an HTTP (Shoutcast, etc), FTP or Microsoft Media Server stream - generally the type of streams you will find on websites. Simply put the complete URL in the URL field.
4. RTSP - Real Time Streaming Protocol, this is another way to stream multimedia. Just put the URL in the text box for it to work.

since when we rely on the UDP, another advantage is we can use it over a proxy server.
Since when TCP video stream is dependent on a particular connection, and there are
limited number of connections a server can handle at same time , it will call close() and
give it to another user. But in UDP this won't be happen like that way.
