Your input source menus are available regardless whether a Web RTC call is active or not.
Audio Output Source's device menu, on the other hand, will only populate while a call is active.
Web RTC is an HTML5 high-definition, peer-to-peer VOIP service.It's also adaptive so it works well with low-bandwidth connections.There are currently three menu options to choose from this drop down: Available to both GM and Players is the ability to disable or enable what you personally wish to transmit and what you want to receive from other players.A couple of examples where adjusting these settings would be useful: If you only own a microphone and not a webcam, you can adjust your settings to transmit voice only.If for some reason a dialog box does not appear or if you wish to change your device settings after the game has started, click on the Red Camera or Microphone icon in the address/search bar to remove the permissions (click on the X beside each device).
A browser tab refresh will bring back the permission dialog box to allow you to change your devices.
The Receive From Others menu controls whether or not you will receive Video and Voice, Video only, Voice only, or Nothing(disable) from other players, if they are broadcasting at all.
If you want to disable Web RTC entirely for you personally, adjust Broadcast and Receive settings to Nothing(disable).
In this situation, you can change your settings to only receive audio and not video to save on bandwidth.
Under Video Audio Chat Options of the My Settings tab are the two options with dropdown menus labeled: I want to broadcast to others and I want to receive from others.
Roll20’s in-browser video and voice feature doesn’t require any plugins or widgets to install in order to use your microphone/webcam to communicate with other players in a game.
