Flussonic Media Server 22.12

01.12.2022

Flussonic Media Server 22.12 has been released.

Flussonic Media Server

Транскодер

Самая главная новость - поддержка аппаратного кодирования AV1. Экономьте трафик используя AV1: Flussonic поддерживает AV1 как на приеме, так и на выдаче. Для использования этой возможности потребуются карты поколения NVIDIA Ada Lovelace и выше.

Intel QSV получил видимые изменения: улучшена работа crop и работа deinterlace фильтров, видео после транскодера выглядят плавнее.

Система конфигурации

Опция config_external теперь доступна не только через переменные окружения, но и через flussonic.conf. Если вы управляете большим кластером серверов, или просто у вас большое количество динамических потоков, то обязательно загляните в документацию, чтобы узнать как настроить Flussonic для работы с внешней системы конфигурации.

Врезка рекламы

Теперь SCTE-35 метки доступны и для DASH-манифестов, заниматься вставкой рекламы на плеере теперь можно не только с протоколом HLS. Захват SCTE35 с MPEG-TS источников теперь работает по умолчанию и не требует ручного включения. Метки будут приниматься с любых MPEG-TS источников: захват UDP, публикация по SRT, перезахват по HTTP MPEG-TS.

Резервирование Multicast

Новая опция позволяет запускать UDP MPEG-TS трансляцию в standby-режиме, т.е. Flussonic не будет отправлять данные в сеть, пока в мультикаст группе есть трафик. Как только обнаружится, что основной вещатель пропал - мы начнем вещаение, а как только вернется - мы остановимся.

WebRTC

Наш WebRTC Player может публиковать видео из canvas элемента, что дает вам возможность накладывать собственные фильтры, логотипы и другие динамические данные на изображение с веб-камеры. Например, можно не ограничиваться “стандартными” фильтрами ОС, а применить собственные “маски”.

Так же мы доработали механизмы, необходимые для качественной работы WebRTC ABR: выбор дорожки, с которой начать проигрывание, улучшили механизм обработки NACK и включили его по умолчанию для всех клиентов.

SDI

В 22.12 мы немало времени уделили и работе с профессиональным оборудованием, это коснулось поддержки и Decklink, DekTec, и Magewell. Добавили поддержку новых SDK вендоров, добавили захват Dolby Digital Audio.

Flussonic умеет не только захватывать аудио и видео с SDI источников, но и поддерживает VBI/VANC, извлекая и субтитры, и телетекст из любых SD-SDI, HD-SDI источников. Так же эти данные можно и отправлять в SDI, образуя SDI-мост между студиями.
