[Galene] congestion control, loss (recovery), whip and obs...

[Dave Taht <dave.taht@gmail.com>]

I would dearly like to be capturing more data and pictures of what
videoconferencing traffic looks like, through the CAKE algorithms in
libreqos. I know that sean put google congestion control (GCC) into
pion and I think now, twitch? GCC was recently "dissed" somewhat in
this paper, but I think it was some old versions in there:

Naturally fq_codel shines. The paper also introduces a new means of
measuring videoconference QoE, called BRISQUE.

I know there are some really complicated high stress OBS setups out there.

I am very interested in the difference between vp8 and vp9 in
particular, in bandwidth demands and loss response.
