Dave,

we have done extensive WebRTC (and several ot= her online meeting=C2=A0
apps) testing lately and this paper
https://ieeexplore.ieee.org/document/9153228 r= eports a=C2=A0
methodology=C2=A0for WebRTC based on Chromium and Selenium Grid and
as tes= t orchestrator Jitsi Torture.

I would avoid feeding clients with BBB as video as i= t is not=C2=A0
representative of a meeting as encoders are optimized for=C2=A0
=
different kind= s of video. There are several video samples=C2=A0
out there.

We have scaled up clients to hun= dreds with this methodology.
The paper is short so many details have been omitted bu= t there
are not many other options to do this kind of test at scale.

Luca=C2=A0
=C2=A0






describes the methodology=C2=A0

It seems plausible to be able to construct a suite of tests that could
indeed track jitter
delay and loss across the internet over webrtc. Perpetually uploading
bigbuckbunny or some
other suitable movie might be an option, but I have a fondness for
extracting a sub 30 second segment from=C2=A0 "Max Headroom", whi= ch if

I guess my question is mostly, is a "headless" test feasible? In = the
context of samknow's lack of webrtc test... lowpowered hw....
