we recently faced issues with the video quality of p2p session.
After a peer is joining a session the quality seems good. But the quality degrades to a bad level fast and the video even turns grey or the stream stops completely. After a while the quality recovers and the quality gets quite good and stable again.
It seems like there is some kind of mechanism that scales down the video quality even though the bandwidth on both clients stays the same all the time.
This only happens on p2p sesions.
