[jitsi-dev] [jitsi-meet] Can adaptiveLastN be a solution for slow internet connection?


#1

Hi,

Cannot find any information how adaptiveLastN works. If a participant
has very slow internet connection, will it affect all participants, so
they will not be able to see all participants, even if all other
participants have pretty fast connection?

Is it possible in addition to adaptiveSimulcast to add a new parameter
that will disable video at all in case of bad con[]nection, so such
users will be able to participate to the conference just listening, or
show only active speaker's video?

Regards,
Zalmoxisus

Did you already see this document[1]?

No, the value of "N" changes per-participant.

that will disable video at all in case of bad con[]nection, so such
users will be able to participate to the conference just listening, or
show only active speaker's video?

This is included in "adaptive last-n": if the connection is detected to be too bad, N will drop to 0 (for the given participant).

Note that both the concept and the implementation are very much a work in progress and there might be glitches.
