Hello ligy8160,

I'm no ARM expert, but your SBC (single board computer) probably needs a 
graphics chip that is OpenGL capable. But you're right, using the FB GUI only 
AGG is supported at the moment.

l1c> 2,I don't know the mean you say about optimize the movie, can you explain 
it ? Thanks.

I don't know what kind of movie you want to play (how it is designed?). Unless 
you tell us a bit more about your project I assume that you created the SWF 
movie yourself, most probably an application.

A simple movie can be played decently on a slow CPU while a complex movie of 
course needs a fast CPU. When your movie is designed in such a way that the 
whole screen needs to be re-rendered on each frame of course playback is very 
slow on your CPU. An extreme case (to make this clear) would be a constantly 
changing background: looks nice maybe, but takes lots of CPU.

On the other hand, having a still movie that maybe only updates a clock text 
label once per second will only need to re-render that part of the screen 
between user interactions, which your CPU should handle fine.

It all depends on what you want/need. Playback performance depends *heavily* on 
the design of a movie...
