Is it possible to change the bandwidth control of every stream during a video chat? Such as, there a 3 participants in a video conference, One in big video tag and others in small video tag. Then we can saving bandwidth by change the receiving speed of small video tag to less value.  
Can I change SDP value by using openvidu?
