Re: GNUstep, sound server and multimedia situation

[Stefan Bidi]

Yeah, I wrote that back when I didn't really know what was up or down.  I went with the source/sink architecture because it seemed like the right thing to do.  The code in NSSound is a bit of a mess, though.  I would like to eventually revisit it, but that doesn't seem likely in the foreseeable future.

That said, there are really only 2 sinks that I know of: libao and OSS.  Libao will use whatever the OS provides, be it pulseaudio, alsa, or something else.  I wrote it as a catch all and as an example for anyone wanting to work with it.  The OSS sink was written by David for FreeBSD... I never tested it.

NSSound is not a multimedia framework, though.  Apple recently came out with AVFoundation, which looks really interesting.  Would be nice if we could get an implementation of that on GNUstep.

A bit of exploration of the source code reveals that at least NSSound uses "sinks" for output.

Some sinks can be found in SVN tree over here:

http://svn.gna.org/svn/gnustep/libs/gui/trunk/Tools/sound/

Header GSSoundSink.h can be found here:

http://svn.gna.org/svn/gnustep/libs/gui/trunk/Headers/Additions/GNUstepGUI/

I don't know more than that.

Hi there.

I've been silently snooping around here for XYZ years, just in case... ;)

And that case is now. I'm in the process of creating a vanilla GNU/Linux
system (largely LFS+BLFS and some C(B)LFS and a bit gentoo and redhat).
It is either going to be a pure vanilla linux or a some sort of
recreation of LinuxSTEP - I haven't decided yet. X-server is installed,
but Windowmaker and GNUstep-packages (base, gui, backends, apps, etc.)
are not.

Anyway - what I need to know is what the situation is in regard to
multimedia and GNUstep. Is portaudio still used as a sound server, and
does GNUstep have a multimedia plugin-architecture a la gstreamer or
translators (as in BeOS+Haiku/Syllable+Pyro-OS)? Or is GNUstep simply
without a multimedia framework atm. ?

Kind regards,

Kristian Poul Herkild
