We have two Jitsi instances on AWS Paris, one of them is t3a.medium (4GB RAM) and another one t3a.small (2GB RAM).
When the smaller instance switches to VP8 (for example when a third participant joins the call), the video resolution is still aceptable (for example 640x360).
However, for the larger instance, in spite of having more memory and CPU and being on the same AWS data center, when the call switches to VP8, the video resolution does never exceed 320x180 for any of the participants.
Both instances have no other calls than the test calls we are doing.
Both instances have essentially the same settings under /etc/jitsi
Both instances are at the latest stable code:
Can the video resolution be tweaked somehow to increase its minimum value?
