-Starting from 1.12(beta) version, SDK provides a new feature called OptimalVideoCount (OVC in short). Goal of this feature is to inform application at run-time, how many videos from different particiapnts, it should render at a given moment in a group call (2+ participants), feature exposes a property `optimalVideoCount` that is dynamically changing during the call based on the network and hardware capabilities of a local endpoint - value of that property describes how many videos from different participants application should render at a given moment. Application should handle these changes and update number of rendered videoes accordingly to the recommendation. There's a cooldown period, around 10s, between updates that to avoid to frequent changes.
