I created a video call application using Kodular + Agora. With it you can make video calls even in groups, with excellent control and response. Well, Agora.io is a video call service, which has more than 200 data centers distributed around the world to guarantee ultra low latency (~ 300ms) and resilience to packet loss (up to 70%). All with 10,000 free minutes per month. In this application I used the CustomWebVideo extension from @vknow360 and the ListPermission created by me. The so-called video page is a responsive local HTML page, which allows for the greatest adjustment in the size of your device.
To use Agora.io, create an account, right after, create a new project and just copy the AppId to your application. If you choose to generate a token, you will need to copy Appid, Channel, Token to the application.
If you need to start a call it is very simple, only you and your friend must be connected on the same channel and on the AppID. I left an AppID defined in the application for you to test.
