VLC is included in the Ports Collection of the FreeBSD operating system. So you can simply install VLC with pkg install vlc.
However you will get a very bare-bone version of VLC. We recommend you to compile it with the following command:
# cd /usr/ports/multimedia/vlc && make install clean
Older versions can be found by browsing our archives
If you want, you can download the source code of VLC media player.
