Xine is a free multimedia player.

xine is a free (gpl-licensed) high-performance, portable and reusable multimedia playback engine. xine itself is a shared library with an easy to use, yet powerful api which is used by many applications for smooth video playback and video processing purposes.

Here are some key features of "Xine":

· xine is fast:
· All included decoders are optimized to use MMX, MMXEXT, SSE and 3DNow! acceleration if available. The well designed architecture moves data efficiently across plugins without requiring extra memory copies to be made. Multi-threaded implementation provide big gains on SMP systems.
· xine is extensible:
· Plugins are probed on startup and new ones may be installed from third party (although the most important are already provided).
· xine is reusable:
· All described features are available from a library and may be called from other applications. A default X11 GUI (xine-ui) is available but any other frontend can use the xine-lib too. There are several of them already available: gtk (gxine and sinek), gnome2 (Totem), gtk2 (GQoob), scriptable console (toxine), kde (kxine), kdemultimedia (xine aRts plugin) and even a Netscape/Mozilla plugin. (some frontends may be at beta stage)
