WebRTC ABR control

Question

Hi Antmedia

We are testing out your media servers enterprise 1.9.* for use in 1-to-many low latency broadcasting. the main protocol is webrtc due to it's latency, and as a fallback we have HLS .
viewers are globally located, some in places when we cannot place an edge close by. 

So we are mixing webrtc clusters with HLS CDN to cover most viewers needs. but we are finding that the webrtc's ABR is not all that good, it often goes to lower resolutions then needed. 
so i'm not confident the current WebRTC ABR logic is good enough for our needs. 


I understand the WebRTC ABR is control by the server, and not by the player as it is with HLS.  
so  with webRTC is it possible to let the viewer select which quality from at available ABR channels (overriding the default server side logic) ? . like is commonly seen on HLS player where user can select from a set of resolutions or auto/adaptive
and have the ABR logic improved with version 2.0? 



Kind Regards
Jan Petersen
