KMPlayer is a video player plugin for Konqueror using MPlayer, Xine or GStreamer.
Like MPlayer, the Xine and GStreamer backend are out-of-process players. So it will not crash konqueror when Xine or GStreamer crashes.

Also a simple tool for video playing and recording. Supports many playlist formats, including podcast RSS/Atom, plays all links directly from the internet. Other specialties are DVD, VCD and VDR support.

Here are some key features of "KMPlayer":

· play movies from file/url using MPlayer, Xine (with *kxineplayer) or GStreamer (with *kgstplayer), making the plugin support as many as possible and, because all three are embedded external programs, keeping konqueror from crashing,
· keep movie sizes ratio
· volume slider using backend players' volume control and a volume slider using kmix or sound mixer applet (kicker) in the pop-down menu,
· position slider
· Javascript support for controlling the plugin from web page's javascript, and of course preventing script errors on pages calling these functions,
· 'Click to Play' support for QuickTime's HREF attribute,
· lots of attributes supported, AUTOSTART, FULLSCREENMODE, CONSOLE, CONTROLS etc. Also, the CONSOLE/CONTROLS for RealPlayer plugin, allows KMPlayer to 'split-up' over multible objects,
· bookmark menu in the popup menu, so you can easily bookmark a stream for later w/o having to visit the web site all the time,
· support for typical used playlist formats as ASX, RAM, m3u, pls and partially SMIL and a dockable viewer for it. This allows you to easy navigate or bookmark certain streams.
· recording using mencoder, mplayer -dumpstream or ffmpeg
· resize/fullscreen support
· proxy settings from konqueror are used to set http_proxy environment variable for backend processes,
· configurable pattern matching for MPlayer and easy Xine configuration editor

The stand-alone player (libkdeinit_kmplayer.so) shares its core (libkmplayercommon.so) with the plugin's (libkmplayerpart.so) one, keeping both plugin and stand-alone player as lean (and secure) as possible.

Actually, I wouldn't be suprised if the majority of KMPlayer users only use the plugin and use one of the other great movie players for KDE for other means.

The stand-alone application can additionally:

· play DVD (DVDNav only with the Xine player)
· play VCD
· let the backend players play from a pipe (read from stdin)
· play from a TV device (experimental)
· show backend player's console output
· launch ffserver (only 0.4.8 works) when viewing from a v4l device
· DCOP KMediaPlayer interface support
· VDR viewer frontend (with *kxvplayer), configure VDR keys with standard KDE shortcut configure window
· Lots of configurable shortcuts. Highly recommended for the VDR keys (if you have VDR) and volume increase/decrease.

What's New in 0.10.0c Stable Release:

· This release is for enabling flash support in Konqueror using either the swfdec-mozilla plugin or Adobe beta's. Also allows adding YouTube 'embed' tags to the playlist so these movies can be played directly in KMPlayer.
Pushed out earlier than planned because of compile errors of previous releases with gcc-4.2.

What's New in 0.11.0 RC4 Development Release:

· Silence most of the QDBus warnings about missing members or spurious replies
· Fix crash in npplayer for the GetVariable call from Javascript
· Bookmark updates from Edgar Klingberg
· Commented out lo
