Flussonic Media Server 22.02

01.02.2022

Мы выпустили Flussonic Media Server 22.02.

Flussonic Media Server

Теперь Flussonic умеет досылать потерянные UDP-пакеты в ответ на сообщения от браузера. Это позволяет совместить минимальную задержку и передачу видео без артефактов даже при нестабильном интернет-соединении.

Добавлена поддержка кодека AV1.

Ознакомьтесь с полным списком улучшений и исправлений ниже и обновите ваши серверы как можно скорее!
