The network live Broadcast system implemented using LIVE555 class library

LIVE555 has four main class libraries:

Libusageenvironment.lib;liblivemedia.lib;libgroupsock.lib;libbasicusageenvironment.lib

After the four class libraries and related header files are imported into vc++2010, the webcast system can be easily implemented.

Here directly affixed to the complete code, paste into the VC inside can be run.

Note: After the program is run, use the Player software (VLC Media player,ffplay, etc.), open url:rtp://239.255.42.42:1234, you can watch live video.
