VK Calls: a video conferencing platform with no limit on the number of call participants

Day 2


Ivan will talk about the structure of calls on WebRTC, what are the difficulties in implementation and how they were solved in the VK Calls platform. Part of the presentation will be devoted to scaling calls for thousands of users: why a call with thousands of participants is not started "out of the box", how VK has a high-loaded call backend, where the bottlenecks arise and how to overcome them. Ivan will also dive into protocols and codecs to figure out how to achieve high clarity for 4K screen sharing.
