A DVDplayer
-----------
1) set up a pipeline
<draw pipeline schematics here>
2) set to playing
- dvdnav reads the ifo file. A set of events are generated to configure
various elements in the pipeline. These would include:
- SPU colors
- whatmore..
- first the src will read the DVD menu. this will contain mpeg2 data
and spu/nav info. after the menu is sent down the pipeline
the nav decoder waits for input somehow. The pipeline keeps on
playing to animate the menus.
- somehow a button is pressed on the menu: a method is triggered in
the dvdnav plugin to tell it button X was pressed (event? app?).
- dvdnav reacts and starts to stream other data.
- nav packets in the stream indicate what can happen next.
- update the menu
- keep the menu
- hide the menu
- show the menu
- pressing the hotkey to bring up the menu triggers a method in dvdnav
which will send down nav info downstream to bring up the menu.
A background picture (I frame) is sent downstream too.
- nav info can also happen while playing the movie. This can highlite
some buttons the user can press.
- selecting a button triggers some color/compositing changes in SPU/NAVdec
and an action on dvdnav.
