Video calls for the first 30 voice chat participants.

Video calls for the first 30 voice chat participants. In Telegram for Android 7.8.0 Beta, video functionality is available only for the first 30 participants of the voice chat. It means that the 31st participant will no longer be able to see other users' videos or broadcast their own. For such participant, the chat will become just a voice chat: you will be able to speak yourself and hear other speakers. Currently, chats are tested with this restriction, the limit will be increased in the next updates.
