Facebook has given the support of Live Videos but many users are complaining that not everyone is alerted of the Schedule of Live streaming.
Facebook is aware of this difficulty, which is why, it has given Live Video Schedule support to some verified pages.
The thing to remember is that it is for verified pages and not verified users.
After this update publishers can advertise their live videos in a better way. Before this pages used to advertise their Live Videos through posts and status. With this feature page makes announcement post for follow over. The post reminds users of Live Video.
With this update, users can also chat in pre-broadcast chatroom.
Currently pages can schedule video as per API.
