Swfdec - Oct 2007 - swfdec performance

Hi ,
  I am new to swfdec development team.    I am studying the swfdec V
0.5.2source code.  I found that it requires more horse power.  I
played SWF 7
content with  the swfplay on 500MHz AMD CPU, performance was too bad.  Audio
was not playing properly and video is slow.  I played the same content using
*firefox with Adobe's macromedia flash plugin* on same hardware,
performance is too good.   Also I did few experiments with swfplay.  I found
major performance bottleneck is with usage of *cairo* graphics library.
Even some times audio doesn't play in Fedora 7 running on  AMD 1.7 Ghz
processor.  I  have following queries related to the swfdec


   - Is it possible to port swfdec to SDL or X-Server or DirectFB or GTK
   without using cairo library?
   - I am interested to improve the swfdec v0.5.2 performance and porting
   to other graphical library.  I would like complete this task within a month.
   Can  I get complete support from the developers and also  architecture
   document, design documents .


Thanks and regards
Jnanesh

Of course it is possible to do this, if you want to write a rendering
engine that is reasonably complete at implementing the PDF drawing
model. None of the libraries you just listed does that. They all just
copy rectangular images. Unless you use OpenGL, I doubt you get
anything faster than Cairo. But feel free to try.

That's another thing where I'd be very surprised if you'd manage
that.
Learning the code of a reasonably big part of code (Swfdec is ~50.000
lines) takes the largest part of a month.

You can get complete support from the developers for anything and at
almost any time by dropping into the #swfdec IRC channel and just
asking questions. We're always happy to help (unless we are on
holidays like the last weeks.)
As for architecture or design documents, I'm afraid that those don't
exist in a separate form. We use the source code as documentation.
Parts that aren't self-documenting get comments added. The code is
still changing far too rapidly to keep those documents reasonably up
to date.

Cheers,
