Hello Guix,

Disclaimer: my employer is Savoir-faire Linux, which oversees the
development of Jami.

For a while, I've toyed with the idea that we could leverage Jami for
our video-conference needs, and contributed a jami-service-type a few
months ago to ease doing so [0].

A service is not strictly needed to setup a video-conferencing server
(later referred as a "rendezvous point") with Jami [1], it increases
availability and can be used without a normal user session.  It also
provides some isolation from the main system since it runs in a separate
namespace (container), at least on Guix System.

The main challenges for a decent experience with the Jami rendezvous
point feature is its resource requirements; as the number of
participants grow, so does the required amount of network bandwidth and
CPU power.

As some kind of technology preview, I'd like to offer a freely available
Jami rendezvous point.  Using either the jami-gnome or jami-qt client
available in Guix, you can connect to it by searching for the
'rdv-jami-guix' contact and initiating a call.  Participants' audio and
video streams will automatically be mixed and streamed by the server.

On a Guix System, installing it to your user profile should suffice.  On
a foreign distribution, you'll have to resort to a more complicated
launch procedure, thanks to D-Bus configuration [2].  Something like this
should work:

$ guix shell jami-gnome dbus glib gtk+ openssl nss-certs \
    -- dbus-run-session jami-gnome

I hope it proves useful in fostering more live collaboration in the
community!  Extra rendezvous points could also be deployed if needed.
If the experience is successful we could seek a better place to host
such service for the community (where it could be managed by the
collective of Guix sysadmins rather than myself for example).

Happy hacking,

Maxim

Thank you :-).  It was a difficult service to tackle (with the D-Bus
requirement and D-Bus communication); I especially struggled with making
it rock solid in terms of being able to restart it without any glitch
(the test suite verifies this).

I hope it can be useful!

Thanks. I just added it to my contacts. I hope I can get a mic [and camera] soon to try it out.

It seems to work like a charm.  \o/


Thanks again for sharing this resource.

It works very well – on foreign distro at least. :-) We tried this
evening with Julien.  Well, it is probably because long-distance, we
noticed a delay between sound and video.

I hope hack sessions will be organize soon.  Ah, just for my
information, is it possible to share a screen or something?

Thanks for sharing this very useful resource.


Cheers,
simon

Thanks for the feedback!  I'm glad it worked OK.  Audio and video
synchronization issues are relatively common in Jami (I'm guessing it's
a difficult problem!), especially on systems lacking video acceleration
(such as mine -- GPU vendors typically require binary blobs to drive
their video decoders).  Where video acceleration is possible, I think it
takes care of the synchronization problem itself, which explains why it
often works better there.

Yes, both desktop clients (GNOME and Qt) support it.

My pleasure!  I'm happy to hear it may be put to good use!

Ah yeah, right-click on the video call screen.  It was not obvious. :-)
I was expecting a button bottom. ;-)

Thanks,

The UI is decidedly not without its quirks, especially the GNOME client.
jami-qt on the other hand (which is to become the flagship Jami client)
has had the attention of a professional UI designer so it is more
intuitive and polished in my opinion.

Happy conferencing ;-)
