Is GStreamer live? (in connection to Squeak)

Good time of day.

I wonder if there is anyone who use GStreamer-related plugin/packages. Packages are marked as last updated near Nov 2008, they do contain errors as I can judge, and absolute lack of documentation. Then, after I'd loaded GStreamer into precompiled All-in-One-4.2, code

GStreamer default.

immediately raised plugin initialization error - primgstinitcheck - primitiveFailed (on Debian GNU/Linux amd64).
In locally compiled Squeak, GStreamer connections do work, I succeeded (after fixation of a couple of obvious errors) in constructing easy audio chain and playing OGG/Vorbis from file to ALSA. Is GStreamer plugin/classes supported these days, is there anybody interested in?.. :-) :-(

I am sure Scott, Yoshiki, John or Bert can offer an accurate reply,
but in the meantime here is my rough guess of the situation.

As far as I recall, the GStreamer plugin was built by VPRI for the
OLPC XO-1 laptop. (The laptop's Sugar software platform is a
customized spin of Fedora Linux.) There was no effort I am aware of to
use GStreamer on other platforms.

The current Etoys images are based on Squeak 3.8 with a great deal of
bug fixing and additional code. They work on most recent VMs. (The
current version number 4.1.1 is merely a coincidence and has little to
do with Squeak 4 images.)

If you can port the image code to Squeak 4.2 or trunk, I am sure it
will be useful for all kinds of other Squeak uses on Unix/Linux.

Hope that helps until you get an answer from someone who actually uses
it or maintains it.

John made it work once on Mac OS X, but it's a major pain in the neck to compile. The main platform is Linux.

I think maintenance is up for grabs. GStreamer is a great framework for media playback and deserves more attention.
