OK. I would suggest that you add a Freshmeat listing though, since it's
not listed there (and that's most people's way of searching for programs
these days, RIP sunsite [kinda])

OK, I've heard of him.

Right, that's what I mean. I need to go back in my mail archives and find
Tim Janik's post about the basic architecture of it, then go poking around
in source. I'll wait for 1.4 to come out before moving over, just because
I don't want to put a moving target on top of a moving target... <g>

True. I guess it wouldn't be that hard to have a few Bonobo wrappers for
the core data types (corresponding to all the files in gst/, the idea is
that the plugins use standard interfaces provided by these core types, for
maximum plugability) and expose those via IDL. I need to read up on
Bonobo some more, and figure out where on earth my CORBA book went...

Right. This meshes with the stuff we're doing at work, though we're doing
a client/server video streaming demo.

Ouch. That sucks.

OK, I'll go over it in more detail. I did see lots of references to
GStreamer, and even a verbatim copy of the docs ;-) Cool!
BTW, just so you know what I'm up to on the sidelines, I'm interested in
an audio editting program, a la Cakewalk or VST Cubase, as well as a form
of that with a twist: live. I've found that every audio package claims
real-time, but not live. There are no packages that turn a multi-channel
sound card into a live mixer. I'd like to come up with a library and
application (that sits on top of GStreamer, of course) that provides the
necessary functionality to do this. The library idealy would be designed
generally enough to do any kind of media editting functionality. This
means that a lot of code you have in Trinity could be very similar to
what's needed for audio processing, at least in the offline NLE-style
editting app. Something to keep in mind...
