[Galene] Re: How to read stats information

Up/Down: the direction of the stream ("Up" means client->server).

The first number is the bitrate, the second is the maximum bitrate within
which Galène is trying to fit (estimated by congestion control).

0% is the estimated packet loss rate.

The last figure is the RTT and the estimated jitter (for down streams only).

You're referring to this stream:

> Down	969a21a58e75227f0cb06a84924815e9	24503
> 30488/9600	37%	59.869669ms±4.625ms
> 299800/14903	0%	61.573201ms±5.477777ms

The user is having 37% packet loss rate, which is extremely high.  The
congestion control algorithm has dropped this users rate to 24503 bps
(9600 for audio, 14903 for video), which is way lower than Galène can
possibly achieve.

Either the user is behind a very slow link, or they're behind a WiFi link
with extremely high loss rates.  If the former, they should disable the
video feed (Receive->Nothing).  If the latter, which is more probable,
they should move around until reception is better (there's probably
a couple of carrier walls between them and the router).
