[jitsi-users] A demo video: WebRTC, Jitsi Videobridge and COLIBRI

Archive
#1

Hey all,

A few of use have just created a sample video showing Jitsi Videobridge and WebRTC in action. You can check it out here:

For those of you who haven't had the chance to learn about the bridge yet, it acts as a video relay or, more preciesely, a Selective Forwarding Unit (SFU), that mixes audio but keeps video streams separated when forwarding them to all participants in a conference call.

This allows for a great scalability potential contrary to other approaches like full mesh conferences or content/composite mixing.

The reason you are seeing a burst of Jitsi Videobridge related posts lately is because we have recently made it compatible with WebRTC by adding to it DTLS and ICE support (kudos to Lyubomir Marinov). This means that it can now be used to build video conferences in a web page like the video above shows.

The actual JavaScript application in the video (which we will make publicly available very soon) is built by Philipp Hancke from Estos. It uses the COLIBRI XMPP protocol extension ( https://jitsi.org/colibri ) to control the Jitsi Videobridge. It also uses XMPP Multi-User Chats (MUCs) to keep track of and control participants.

All in all this makes for a very neat project and a completely open alternative to Google Hangouts.

You will very likely be hearing more about this in the following days and weeks.

Cheers,
Emil

Cool! It certainly removes a bunch of barriers to entry:
* Users access via web browser (often already installed)
* Users do not even need to register an account to the website

Any plans to support Firefox and other browsers? It looks like it is
Chrome only at the moment.

Also, any plans to migrate away from the ajax.googleapis.com (for privacy).

I really, really like the progress this has made and maybe the VUC will
start using this soon!

One thing that google hangouts also has is the ability to make phone calls
out. If not already possible, will it be integrated to make a phone call
out on a particular SIP account?

#4

Currently I get a 404 Not Found error on browsers other than Chrome.
On Firefox it redirects to: https://meet.jit.si/chromeonly.html
On Internet Explorer it redirects to:
https://meet.jit.si/webrtcrequired.html

Could you add a simple HTML page that says, "meet.jit.si currently works
with ..." (with links to browsers that work, maybe Chrome, Chronium?,
Opera?)

This is a great presentation !
Thank you for the update.

I'm sure after having the JS application shared, we will see further
improvement (Such as half full screen if 2 videos peers, quarter a screen
if 4 ppl, etc...)

In term of encryption, any post related to, for me to learn more?

Thank you

Hi Emil,

One extremely odd thing to report...

Replication steps:

0. open chrome on your internet browser chrome
1. go to meet.jit.si
2. copy meeting ID
3. send to android phone via push button so you don't have to type 16
character room ID
4. once link is received on phone, open up link in chrome internet browser
5. do you have one or twe video streams?

I would expect there to be two video streams on both the android phone and
the website on the desktop.

Can anyone else replicate this?

Thanks,
Jungle

Folks

I have tried meet.jit.si. Sometimes the video bridge works, sometimes
not. For example, I just tried it on Chrome from Linux to Windows--the
other party could hear me, see me, and we could chat. But his video
didn't work. I couldn't see him.

When I tried it between three computers on the same network, two
connections worked, the third one did not.

Suggestions?

Paul

This is a great presentation !
Thank you for the update.

I'm sure after having the JS application shared, we will see further
improvement (Such as half full screen if 2 videos peers, quarter a screen
if 4 ppl, etc...)

The basic client code was committed yesterday in
https://github.com/ESTOS/strophe.jingle/commit/f50911516801ec3d7c3645c369e0a8a8d08f3379
and also in
https://github.com/legastero/jingle-interop-demos
I am pretty sure that Lance Stout will soon follow with stanza.io.

What is still missing is the actual colibri implementation in Javascript. I'm cleaning that up currently, watch https://github.com/ESTOS/colibri.js closely.
The way I currently implemented this is a participating focus. However, I would note that you don't need the colibri implementation in Javascript because this could easily be implemented as a bot inside a Multi-User Chatroom or even part of the chatroom itself.

I think it's still possible to hide all those gritty xmppish details under a nice API such as simplewebrtc.com. I already replaced the non-standard signalling of simplewebrtc with standard jingle for https://gowebrtc.me so I am pretty sure the same can be done for the colibri stuff.

In term of encryption, any post related to, for me to learn more?

DTLS-SRTP. Actually, the DTLS session is always between client and bridge, so make sure you trust the bridge :wink:

It is but that question is best asked to Firefox and other browsers. While Firefox have basic support for WebRTC they are still unable to handle multiple streams.

They should be working on that because, they were quite active while advocating for a specific approach to multi-stream handling on the IETF.

Other browsers have yet to officially announce their exact policies concerning WebRTC support.

Also, any plans to migrate away from the ajax.googleapis.com (for privacy).

You mean: would we use a different copy of jquery? I suppose we could, if need be. Although if you are really worried about privacy, you should just use Jitsi (and we'll have a number of very important modifications coming there as well, so the barriers wouldn't be that different)

Definitely some day. Not an immediate goal though. Priorities priorities :slight_smile:

Hey Jungle,

We haven't yet had the time to look into Android support. So far it seems that Chrome for Android might be lacking some aspects of WebRTC support.

I've been having problems on linux for a while (amazingly not on windows). I think I just fixed that with
https://github.com/ESTOS/meet/commit/db7bb50d2841011f832d37cdd0bedfe3c140e397
Yana: can you merge and deploy that?

This seems to be a bug in chrome 31 with respect to DTLS roles... apparently to be fixed in canary, so I'm still looking for the respective ticket.

I hope that increases the success rate :-/

Yep, I suppose we can make mixed audio work nonetheless and check that 1-1 relayed via the bridge works.

Oh, you can run your own instance soon. It's using jquery from a CDN just for ease of deployment.

Dear Jitsi community,

This is a huge development.

Congratulations to all people involved in making this happen.

So, I couldn't resist and did a few trials.

The first observation is that the setup is entirely hassle-free,
which beats Hangout and its plugin from hell, or anything else.

Now, here are my findings based on a single attempt at each configuration.

1/ Start a conference at meet.jit.si from Chrome on a Public IP computer
    Join from Chrome on a computer behind NAT
    Result: Audio works both ways, but only local video is showing, on both
sides

2/ Start a conference at meet.jit.si from Chrome on a computer behind NAT
    Join from Chrome on a Public IP computer
    Result: Audio and Video work both ways

3/ Trying to join an existing conference from Chrome on iPhone doesn't
work, as I was expecting.
    The browser is redirected to
https://meet.jit.si/webrtcrequired.html(which triggers a 404)

I did not confirm the Chrome version number on the iPhone, but on the
computers it was the most recent one.

Also, on the Public IP computer there is an impressive 3 seconds lag in the
local video (although it's smooth),
whereas the local video is pretty responsive and smooth on the laptop.
Should I blame Chrome, or even hardware ?

Looking forward to all the upcoming new developments in and around Jitsi !

Are one and two consistently reproducible? The NAT shouldn't matter here especially if audio is going through. All conference control happens in the JS though so it is more likely that this failed in on of the cases.

Were both Chromes updated versions on a Desktop OS?

3/ Trying to join an existing conference from Chrome on iPhone doesn't
work, as I was expecting.
     The browser is redirected to
https://meet.jit.si/webrtcrequired.html (which triggers a 404)

Yeah. This requires WebRTC to work. Support is not yet everywhere.

I did not confirm the Chrome version number on the iPhone, but on the
computers it was the most recent one.

Hmmm ... that's interesting. Next time you reproduce the issue, could you please "Download the PeerConnection and stats data" under "Create Dump" in chrome://webrtc-internals ?

Also, on the Public IP computer there is an impressive 3 seconds lag in
the local video (although it's smooth),
whereas the local video is pretty responsive and smooth on the laptop.
Should I blame Chrome, or even hardware ?

Maybe ... the bridge is in France though and all video goes through there. If you are doing the test from say ... Japan? then you could be experiencing some issues due to this.

Looking forward to all the upcoming new developments in and around Jitsi !

So are we!

Cheers,
Emil
