Hi,<br>
<br>
The architecture is obviously very influenced by IMS but I've not
tested in a IMS environment but it should<br>
work without problem (note that it is not a MRFC or MRFP so you'll have
to use as an independent service).<br>
<br>
The source code is at<br>

<pre wrap="">sergio, mitul, just a couple general questions: 1. can you indicate again
where the code is? 2. are you applying this in an IMS environment?

<pre wrap="">Sergio,
This sounds pretty interesting, well I m actually not terrified when u
said JAVA :p, we can help you over there since we have java developers
on board.
I would also want to revisit this entire project coz the last time I
did that I had to install A LOT (ye a lot) of dependent libraries.
Also as I mentioned earlier my goal is to make the whole install
SIMPLE, so we might have to build in some sorts of shell script based
installer or mebbe gotta build relevant RPMs( yeah terror for debian
fans like me) but I clarified myself above "SIMPLE".
So let's coordinate n make things moving,

<pre wrap="">Hi everyone,
Currently the mcu solution has two main components, the VideoMixer and
the mcuWeb.
The videomixer component handles ONLY media, i.e. it receives rtp,
unpack audio and video, performs audio/mixing video, encoding, packing
and rtp sending. It is completely controlled by a xmlrpc interface and
has no service logic at all.
The current xmlprc api has the following methods:
-Create/Destroy conference
-Add/Remove participant to conference
-Set conference parameters like video size and number and distribution
of participants on screen
-Set audio/video send/receive ports per participant
-Set audio/video codec and parameters (size,fps) etc per participant
-(Un)Mute participant
-Set conference mosaic positions: lock slot, assign slot to
participant,
etc..
-Add watch only participant to conference (experimental: flash video
broadcasting in web)
It currently supports only h263p but should not be too difficult to
add
support to h264. The rest of the functionalities are completed (except
flash support) and only a bit of testing is needed. In the near
future I
would like to convert the videomixer in a MediaServer, been able not
only to offer multivideo conference services, but also transcoding,
flash casting, etc..
As I said before everything is controlled by an xmlrpc api, so a
component handling the service logic and signalling is needed. That
component could app_conference and the confiance project did integrate
the video mixer as an external unit.
I decided to implement it as a complete external unit from Asterisk.
Why? I think it was easier quicker and easier to develop, avoid the
monolithic and sometimes obscure architecture of asterisk and could
provide much more functionalities. And the chosen technology was..
java
(I feel a great disturbance in the Force, as if millions of voices
suddenly cried out in terror and were suddenly silenced).
Yes, Java, using the Sailfin Sip Application Server
(<a class="moz-txt-link-freetext" href="https://sailfin.dev.java.net/">https://sailfin.dev.java.net/</a>) which allows to create an application
that handles SIP and HTTP request (an application like click to dial
is
just a few lines of code
<a class="moz-txt-link-freetext" href="http://wiki.glassfish.java.net/Wiki.jsp">http://wiki.glassfish.java.net/Wiki.jsp</a>?
page=SipClickToDialExample2). If
you start with your prejudges about java, speed and show on, just
think
that it is a telco grade Sun and Ericsson development.
The mcuWeb component implement the service logic, handles all the SIP
signalling (receiving invite request from asterisk), controls the
Video
Mixer with the xmlrpc and offers a WEB UI to manage the conferences.
This part is also fully functional, but I think that is where more
work
is needed in order to customize the service with the functionalities
needed by the customers. In particular questions like the following
need
to be answered:
- Is it required to create the conference before the user calls? or it
get created when it calls in?
- Are there private conferences? How are the participants allowed to
get
in, by password or by invite only?
- Is there always a default public room?
- etc...
Any thoughts are welcome
Best regards
Sergio
