VLC has support for on-the-fly transcoding of audio and video formats, either for broadcasting purposes or for movie format transformations. Support for most output methods is provided by this package, but features can be added by installing additional audio plugins (vlc-plugin-pulse, vlc-plugin-sdl) or video plugins (vlc-plugin-sdl, vlc-plugin-ggi, vlc-plugin-svgalib). There is also a web browser plugin in the mozilla-plugin-vlc package.
