This code forms a set of C++ libraries for multimedia streaming, using open standard protocols (RTP/RTCP, RTSP, SIP). These libraries can be used to build streaming applications. Since version 2014.08.26, library and include files are arranged to be easily discoverable by configuration stage when building vlc. Since version 2014.11.02, source tarballs from archive at sourceforge.net are used, only the very latest tarball being available from http://www.live555.com/liveMedia/public/. Until vlc (which depends on live555) is updated to accommodate changed API in live555-2021.01.13, live555 will be held at version 2020.08.19
