Hi Qin,

Rewriting the message because the mailing list was not included in the
previous message and my reply was incomplete.

Cheers,

Technically, yes this should be possible. The endpoint measures and
reports inbound-rtp statistics, it could send these to the web server.
However, the web server would have to handle the encoding and
signaling on its own* (i.e., it is outside the scope of our
documents).

Additionally, if endpoint send corresponding XR metrics to the sender,
the StatsAPI should automatically expose these metrics to the
application as outbound-rtp statistics.
