- * OSD Menu
- **********************************************************************/
- /**
- * defgroup osdmenu OSD Menu
- * The OSD menu core creates the OSD menu structure in memory. It parses a
- * configuration file that defines all elements that are part of the menu. The
- * core also handles all actions and menu structure updates on behalf of video
- * subpicture filters.
- *
- * The file modules/video_filters/osdmenu.c implements a subpicture filter that
- * specifies the final information on positioning of the current state image.
- * A subpicture filter is called each time a video picture has to be rendered,
- * it also gives a start and end date to the subpicture. The subpicture can be
- * streamed if used inside a transcoding command. For example:
- *
- * vlc dvdsimple:///dev/dvd --extraintf rc
- * --sout='#transcode{osd}:std{access=udp,mux=ts,dst=dest_ipaddr}'
- * --osdmenu-file=share/osdmenu/dvd.cfg
- *
- * An example for local usage of the OSD menu is:
- *
- * vlc dvdsimple:///dev/dvd --extraintf rc
- * --sub-filter osdmenu
- * --osdmenu-file=share/osdmenu/dvd.cfg
- *
- * Each OSD menu element, called "action", defines a hotkey action. Each action
- * can have several states (unselect, select, pressed). Each state has an image
- * that represents the state visually. The commands "menu right", "menu left",
- * "menu up" and "menu down" are used to navigate through the OSD menu structure.
- * The commands "menu on" or "menu show" and "menu off" or "menu hide" respectively
- * show and hide the OSD menu subpictures.
- *
- * There is one special element called "range". A range is an arbritary range
- * of state images that can be browsed using "menu up" and "menu down" commands
- * on the rc interface.
- *
- * The OSD menu configuration file uses a very simple syntax and basic parser.
- * A configuration file has the ".cfg".
- * An example is "share/osdmenu/dvd256.cfg".
- * @{
