"use-vbr" will configure the encoder in VBR mode - which is the opposite of CBR . This happens once during the call, when the encoder is initiated, and the payload for each packet will have different sizes based on the audio input. "adjust-bitrate" enables a feature in FS that will pass certain information to the opus module during the call and the bitrate of the encoder will be modified based on packet loss / RTT .

in opus.conf.xml what is the difference between adjust-bitrate and use-vbr ? doesn’t variable bit rate (vbr) adjust the bitrate? or do you need both enabled for that to actually work? or do they contradict each other? Any info on this would be greatly appreciated and i would love to document the answer on confluence https://freeswitch.org/confluence/display/FREESWITCH/mod_opus _________________________________________________________________________
