CORBA and bonobo ramblings
|
|
==========================
|
|
|
|
This is about something I know nothing about, so I want
|
|
your views on the subject :)
|
|
|
|
statements in this doc might contain plain nonsense and
|
|
utter ignorance about the subject, so feel free to correct
|
|
no matter how many brown paper bags I need to put over my
|
|
head.
|

|
|
CORBA
|
|
-----
|
|
|
|
The object request broker. It basically allows you to declare
|
|
objects using a language called IDL. It has the nice benefit
|
|
of allowing objects to live in other contexts, languages and
|
|
even on other machines over the network.
|
|
|
|
Wrapping the GStreamer objects in CORBA objects doesn't look
|
|
like a problem. It will immediatly allow us to create objects
|
|
accros the network and use the framework in a distributed
|
|
environment.
|
|
|
|
You will end up with a lot of corba objects using this method.
|
|
Is this the way to do it? do we only need to CORBA-ify some
|
|
of the core objects instead?
|
|
|
|
I see a CORBA wrapper as something that exposes the API of
|
|
GStreamer. If I want to do distributed media processing I would
|
|
build up an app with corba calls. The point is that you use
|
|
the lowlevel CORBA API to create a distributed media app.
|
|
|
|
|
|
Bonobo
|
|
------
|
|
|
|
A component model build with CORBA. Bonobo has provisions for
|
|
creating embedable objects. As I understand it, this means that
|
|
it has something visible to embed. I know you can also use
|
|
Bonobo without the GUI parts but why would we prefer Bonobo
|
|
over CORBA to handle that?
|
|
|
|
Bonobo has a framework to create toolbars, menus and other
|
|
neat stuff. It also has a serialisation mechanism that allows
|
|
you to, for example, merge a pipeline with a document in one
|
|
single stream.
|
|
|
|
I see bonobo as a high level service provider, you create a
|
|
mediaplayer component that can be embeded into a document and
|
|
stuff like that. The point here is that you use bonobo to
|
|
create services out of user apps build with GStreamer.
