<p><font face="Helvetica, Arial, sans-serif">A few questions:</font></p>
<p><font face="Helvetica, Arial, sans-serif">1) Were sound
interruptions consistent across speakers? You wrote "some
people"--were the same speakers affected, or did it vary by
speaker? If so, which speakers? We would like to troubleshoot
this.</font></p>
<p><font face="Helvetica, Arial, sans-serif">2) BBB has
low-bandwidth options at the client level, for shutting off the
video feed, for example. We may want to experiment with that as
well.</font></p>
<p><font face="Helvetica, Arial, sans-serif">3) My connection was
fine, and I detected no interruptions. I used my HP Omen
notebook, Chrome, and a Verizon broadband connection over wifi
including a range extender.</font></p>
<p><font face="Helvetica, Arial, sans-serif">The BBB documentation
(<a class="moz-txt-link-freetext" href="https://docs.bigbluebutton.org/support/faq.html#how-many-simultaneous-users-can-bigbluebutton-support">https://docs.bigbluebutton.org/support/faq.html#how-many-simultaneous-users-can-bigbluebutton-support</a>)
says a server supports up to 150 participants simultaneously,
but no more than 100 per session, with some caveats related to
how many are sending video. We had about 30 on a single
session, of whom only 7 board members and a few intermittent
guests were sending video. Thus we should not have been
anywhere near the outer limits of BBB's capacity. <br>
</font></p>
<p><font face="Helvetica, Arial, sans-serif">I was first introduced
to BBB by OSM India, which used it for my videoconference with
about 20 OSM India members. It was very smooth, with no
problems, which really impressed me given my experience of three
years in New Delhi dealing with the slow and flaky local DSL
connection. <br>
</font></p>
<p><font face="Helvetica, Arial, sans-serif">Would you be interested
in helping troubleshoot this?</font></p>

<pre class="moz-quote-pre" wrap="">Hi,
I joined the board meeting which took place via BigBlueButton (BBB)
today. It was my first time using BBB at all. In the past I have been
using Jitsi a few time at Geofabrik at our own, password protected
instance with up to 5 participants and about 10 users on a different
non-public instance.
I did not observe video issues during the board meeting as I am used to
with Jitsi. This means, there were no users forced to reconnect because
they saw frozen video streams only (but sound still working and others
still seeing normal video streams).
However, I observed audio issues with BBB. They impaired my ability to
understand some people heavily. If my English were not as good as it is
now, I would not have been able to understand them at all. The sound by
some people was interrupted for fractions of a second almost every
second making following them very difficult. I observed the issues with
almost any board member but not all the time.
I changed my connection from wifi [1] to LAN to exclude any radio
related issues but it did not resolve the problem. My notebook was not
at 100% CPU. I was using Firefox and a Deutsche Telekom VDSL 50 MBit [2]
as single user in the house.
I have not observed these issues with Mumble for the last few years.
There had been issues with single Mumble users during a conference but,
as said, they were limited to single users only. I presume that the
presence of video streams needing to be transmitted to the recipients
takes to much bandwith and, in contrast to Jitsi, audio is not
prioritised although it being way more important for understanding than
a smoothly moving image. However, I have no proofs for that theory and
the used BBB instance being overloaded or its network connectivity could
be another potential reason.
Did anyone else have similar issues?
Best regards
Michael
