VLC (initially VideoLAN Client) is a highly portable multimedia player for various audio and video formats, including MPEG-1, MPEG-2, MPEG-4, DivX, MP3, and OGG, as well as for DVDs, VCDs, and various streaming protocols. It also can be used as a server for unicast or multicast streams in IPv4 or IPv6 on a high-bandwidth network. The most prominent additions to version 0.8.6 are probably Windows Media Video 9 and Flash Video. Other important changes are improved H.264 decoding, better Windows Unicode support, and a full-screen.
