[jitsi-users] tried https://meet.jit.si/ and get long audio delays


#1

Have I made some wrong assumptions? Are the server parts helpful installed on your
local computer behind a wireless/LAN router?

Should I be installing jitsi-videobridge on an internet-facing server only, or
at my workstation also?

The delays were several seconds, so not explained by the geo locations of me, jit.si
at jit.si 91.121.47.14 with a ping time of 111 ms.

Hi,

jit.si is a different server and has nothing to do with meet.jit.si.
The meet.jit.si is deployed in several regions signaling and jvb nodes
(ap, europe, us).
If you are interested in RTT make a non p2p call on meet.jit.si, open
your local info and you can see the bridge ip address and try pinging
that one.

A delay of several seconds is not normal, but I'm a little confused on where you experience it.

Are you using the https://meet.jit.si service in your browser as the title indicates? If so, then there is nothing extra that you need to install.

Can you tell us more about the situation: what browser are you using, how many participants are there in the conference? On the thumbnail on the lower right there is a little "gsm bars" icon. If you hover over it you should see some details about your connection. You can try turning off you video to see if that affects the audio quality and delay.

Also note that with two participants the connection might be p2p and not go through a server (and if it does, it does not use jit.si).

Regards,
Boris

Yes, I tried a 2 person video call using https://meet.jit.si/my_url

I used chrome browser Version 60.0.3112.78 (Official Build) (64-bit)

connection. You can try turning off you video to see if that affects the audio quality and delay.

Also note that with two participants the connection might be p2p and not go through a server

So, if p2p, can the video formats be wrong and cause big processing to convert on the fly, thus hitting bandwidth limitations?
I have about 3Mbps out and 30Mbps inward, and the other person was using wifi at a coffee shop.

Is there a configuration file possible, or settings for the camera? Can video format be chosen, or do I need to fiddle with
creating a virtual camera that outputs a certain type of video MJPEG, H.264, etc. to get results?

There is a a "device settings" panel accessible through the menu on the left. However, apart from selecting which source to use you shouldn't have to do anything.

The video codec is chosen automatically, and the bandwidth limitations are also handled automatically -- the video bitrate is dynamically configured based on estimated bandwidth.

In the case of a wifi at a coffee shop, I would suspect that the connection was not good. In such a situation you can try to use the "audio only mode" (the circular button on the top right next to the thumbnails) to save bandwidth (this should also be done automatically, but may not always work well).

Boris
