I figured out that defining "config.resolution: 720" allows users to
send camera streams with a higher resolution than by default. However
it still very rarely goes above 640x480. The server flying the
videobridge is well below 100% CPU - same for the clients. We tried
with 2 and 3 participants with an internal laptop and external Logit*ch
USB camera but could not improve the quality. All participants were on
the same gigabit LAN.
Any ideas to improve the quality? Thanks.
