[sip-comm-dev] the FOSDEM chronicles


#1

Hey all,

As most of you already know, we had a stand allocated at this year's
edition of FOSDEM. This was a nice occasion for all of us to meet and
spread the SIP Communicator love among our fellow geeks ;). Well ...
mission accomplished! 100% at that!

Our stand was located right against the entrance of the AW1 building,
between those of SUN, MySQL, FOSDEM, and xmpp.org. In addition to the
many people that had just discovered the project we could also meet
and chat with members of related communities like Marcel from Felix,
Daniel, Stefan, Dan and all the other folks from SIP Router, Peter and
the rest of the folks from the XMPP Standards Foundation, Diana from
YATE, Leslie from Google and all the others that are currently eluding
me but that were just as fun to meet.

We could also chat with the VoIP area deb package admins for Debian and
Ubuntu (I'll be mailing them these days so that we could start working
on SC's integration in their repositories) and got a chance to ask a few
questions about the future of JMF to Sun's Simon Phipps and Mark
Reinhold (hopefully we would get the answers one of these days, so stay
tuned). There were many other quite interesting meetings and I would
certainly not be able to recount them all today, so I guess I'll be
referring to them in future related discussions on this list.

Concerning the demos. One of them consisted in showing ZRTP encrypted
Audio/Video calls with SC. The fact that we were able to present an
encrypted session was extremely important as it corresponded to FSF's
objective for a Skype replacement. I would therefore like to thank
Werner for his work on completing ZRTP encryption and fixing the bugs
that were discovered. Werner, hope you'll be able to join us next time
so that we could celebrate together!

Speaking of video calls, you should all know that throughout the entire
weekend we successfully established exactly TWO such calls ...

... if you are now asking yourselves what prevented us from having more
than two the answer is: Well we didn't need to :). Both video calls
went uninterrupted throughout the whole day without losing quality or
accumulating latency. I don't think I expected them to fail, but since
one doesn't get a chance to test this every day, it was still quite of a
show even to ourselves.

In addition to being stable the demo ran really very well - we had
excellent quality in both full and non full screen modes, and on both
Linux and Mac OS X. The latency was also perfectly acceptable and many
visitors found it better than what they claimed to experience with
Skype. Therefore many thanks to Damian and Lubo for all their work on
integrating and polishing ffmpeg and lti-civil on all operating systems!
Great job, guys!

Our second stand demo was a showcase of the work Cristina did on porting
SIP Communicator to Android. The demo attracted a lot of interest from
different people so we would hopefully be getting more contributions for
the sc-android project in the near future. Cristina, I know that your
week before FOSDEM was quite busy so thank you for finding the time to
prepare the demo despite that.

Finally I'd like to thank Ben, Cristina, Damian, Damien, Enrico,
Julien, Ken, Lubo, Martin, Pavel, Romain, Seb Mazy, Seb Vincent, Ulrich,
Vincent, and Yana who participated by presenting SC to our stand
visitors and by proudly wearing their SIP Communicator jackets all over
the place. Thanks to all of us our participation at FOSDEM was extremely
successful and I am confident that this will soon translate into new
contributions and elevated interest in the project.

Thank you all, and hope to see you again in Brussels next year!

Cheers
Emil

P.S. To all our correspondent photographers: feel free to send here
links to the photos you took on FOSDEM. I believe everyone is looking
forward to seeing the footage :wink:

Email,

thanks for the wonderful report. I'm glad it worked well at
FOSDEM.

Just a small wish:

....

Concerning the demos. One of them consisted in showing ZRTP encrypted
Audio/Video calls with SC. The fact that we were able to present an
encrypted session was extremely important as it corresponded to FSF's
objective for a Skype replacement.

...

Is it possible that you can do a screen shot when SC uses an
audio _and_ video session? This way I would see if both session
display the right data. I never tested ZRTP's multi-stream feature
in "real-life" with SC - only with my internal test programs

Thanks.

Regards,
Werner

Hey all,
I agree that FOSDEM'09 (my first) was really enjoyable for me. I met number
of interesting people (those include ones from sip-com :slight_smile: ), listened to a
lot of interesting talks and proudly wore Sip-communicator jacket all over
the place. So thank you all for making it such a great event.

I also made few photos so I am posting them too:

So I hope to see you all next year on Fosdem

Hello,

Yes, that was a nice trip and above all the booth was a great success. Congratulations to the demo-makers! More pictures of the trip here (~90 Mo):

Hi Werner,

Is it possible that you can do a screen shot when SC uses an
audio _and_ video session? This way I would see if both session
display the right data. I never tested ZRTP's multi-stream feature
in "real-life" with SC - only with my internal test programs

Yes we will send you a screen shot as soon as I meet Lubo so we can make such a p2p session.
Most probably it will be on Monday or Tuesday.

My fault as I forgot to do it on FOSDEM :slight_smile:

Hi,

I finally managed to make a screen shot. Also as Romain said video is not secured.
But audio security is on and working :slight_smile:
