[Galene] poor screen sharing quality on galene (vp9) when the cpu is not strong enough.

[err404@free.fr]

Dear all

yesterday I tried galene on the official web site with vp9: https://galene.org:8443/group/public-vp9/

the video stream quality was good
but when I tried to share my screen, the screen sharing quality was uggly, really...
even on a not moving screen (displaying static text).
and even after many seconds, the quality remain very low. (even when cut off the webcam stream)
it is appear that every second (or two), the quality drop again to ugly. (seem the stream was lost and restarted)

at this time, the cpu was not at 100%.
(it was at 100% when I activated the webcam)

I tried the option blackboard mode (hoping it will affect the screen sharing quality), but not, or not enough.
I tried to send everything

I tried the same on another computer (better cpu, better graphic card), the quality was better on screen sharing

I though that sharing a static screen was easier than streaming a 720p webcam :p

I am ready to do some another tests if you need.
