| 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. |
