* 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
*
* 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:
+ * A subpicture filter is called each time a video picture has to be rendered,

*
* 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",
* 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".
