Flussonic Media Server 22.09

01.09.2022

Мы выпустили Flussonic Media Server 22.09.

Flussonic Media Server

Поддержка SMIL-файлов для создания мультибитрейта. Мигрировать на Flussonic с другого медиасервера теперь проще. В случае, когда у вас уже есть библиотека медиа файлов с разным качеством, не придется тратить время на изменение порядка каталогизации или производить другие манипуляции. Поддержка SMIL позволяет указать путь к файлам, благодаря чему файлы с разным качеством соберутся в один мультибитрейтный плейлист. Работает как в случае с локальными, так и облачными хранилищами.

В этом релизе серьезно увеличена точность OCR-распознавания субтитров всех языков при конвертации из DVB в WebVTT. Мы замерили точность распознавания венгерского и румынского языков – она выросла с 57% до 92%. Воспользуйтесь функциональностью конвертации субтитров из DVB в WebVTT, если вы принимаете во входящем MPEG-TS потоке DVB-субтитры в виде растрового изображения и хотите иметь возможность показывать субтитры на мобильных устройствах и плеерах без поддержки DVB.

Для комфортного запуска Flussonic в Kubernetes мы поддержали JSON логи и хранение тегов в Docker Hub (теперь можно установить не только последнюю версию Flussonic, но выбрать из нескольких последних).

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

Что нового

  • #8943 (new) (Flussonic) Significantly improved the quality of subtitiles recognition with Tesseract tool.
  • #9797 (new) (Flussonic) It is now possible to use SMIL files for VOD adaptive bitrate streaming. SMIL files allow to make playlists for different combinations of files with different bitrates.
  • #17686 (new) (Flussonic UI) Added the “Timeout” option in the “Push live video to certain URLs” section on the “Output” tab of stream settings.

  • #24453 (improved) (Player) HLS stream now does not load data in the background when autoplay=false is used, so it does not generate unnecessary playback sessions. This is important for playing statistics accuracy.
