VLC Media Player: The Cone Knows Its Formats
The world of open source software has ample choices for editing and manipulating audio and video media files. But when you just want put your feet up and relax, fewer really ideal options are available. One solid choice is the Gxine is a media player (See my review here). But an even better pick is the VLC Media Player.
The VLC Media Player is a cross-platform media player that runs on Linux, Windows, Mac OS X, BeOS, BSD, Solaris, QNX and PocketPC.
One of its coolest features is the built-in streaming server. VLC Media Player streams in unicast and multicast in IPv4 or IPv6 on a high-bandwidth network. You will not find this combination in most other media apps.
