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.
