Flussonic Media Server 22.04

Мы выпустили Flussonic Media Server 22.04.

В транскодер добавлена опция split_channel. Она позволяет разделить каждую аудио дорожку с несколькими каналами на отдельные дорожки. Опция полезна для проведения мероприятий (event стриминг), когда есть вынужденная необходимость упаковывать разный аудио контент (разные языки, музыку) в одну дорожку.

Начальную дорожку для адаптивного проигрывания по WebRTC теперь можно выбрать персонализированно для каждой сессии проигрывания. Таким образом, каждому пользователю можно выставлять индивидуальное качество по умолчанию.

WebRTC плеер теперь показывает доступные разрешения, поддерживаемые камерой. Это полезно для сценариев, когда пользователю необходимо вручную выставить , например, максимально высокое или максимальное низкое качество видео, которое он публикует.

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