sounds quite interesting, unfortunately I didn't see much on your web
page, I don't have flash installed here. Could you give me some more
details about it? Is it free of charge and free software?

thanks :) Our goal is definitely to build a (re-)useable x11 media player,
yes. what stream formats do you intend to use for your project? mpeg?

we are heavily working on it. I'm currently reviewing the whole xine code,
cleaning up the interfaces, throw out all the global variables ... looks
good and hopefully gives us (besides more readable) more stable code.
Daniel is working on the split-up from the automake-side and he sais he's
nearly done with it, so you'll see three new modules in xine-CVS soon:

- libxine : the xine "engine", including mpeg2dec, ac3dec, input plugin
            handler/loader, demultiplexers, win32/avi code
- xineoutput : audio and video output drivers for xine, currently
               for alsa/esd/oss (audio), x11 (video)
               we're planning to support things like framebuffer
               devices and hardware decoder cards, but that'll take
               some time
- gui

each should have clean interfaces and it should be possible to replace
each one by a specialized version (I guess you'll replace the gui and/or
output routines to embed xine in your application).

remember that this code is GPLed (not my favourite license, but it's the
choice of the mpeg2dec/ac3dec developers so we have to use it. Because the
GPL is a virulent license this will probably mean that whatever you build
on top of xine will have to be GPLed too.


> can i help?

any help is appreciated. as soon as I'm finished with my review (hopefully
very very soon ;)) andf we have the three modules in CVS the code should
bevery modular and diferent developers could work on different parts of it
(that was a problem with the current "hackish" design). Perhaps you want
to work on something like a gtk/gnome gui or a gtk xine widget ?

cheers,

grats :-)

hummm - so I guess you based your work on a 0.3.x version of xine?

wow - hey, this is something I'm dreaming of for quite some time. A
quicktime demuxer and ... perhaps the ability to use xanim plugins??
This would give us 3ivx support for free! :-))

Cheers - hope to hear from you soon,
