Transcoder

The biggest news is support for AV1 hardware encoding. Save traffic using AV1: Flussonic supports AV1 both on reception and on output. To use this feature, you will need cards from the NVIDIA Ada Lovelace generation and above.

Intel QSV has received visible changes: the work of crop and the work of deinterlace filters has been improved, videos after the transcoder look smoother.

Configuration system

The option config_externalis now available not only through environment variables, but also through flussonic.conf. If you manage a large cluster of servers, or simply have a large number of dynamic threads, then be sure to take a look at the documentation to find out how to configure Flussonic to work with an external configuration system.

Advertising insert

Now SCTE-35 tags are available for DASH manifests; inserting advertisements on the player is now possible not only with the HLS protocol. SCTE35 capture from MPEG-TS sources now works by default and does not require manual activation. Tags will be accepted from any MPEG-TS sources: UDP capture, publishing via SRT, recapturing via HTTP MPEG-TS.

Multicast Reservation

The new option allows you to run UDP MPEG-TS broadcast in standby mode, i.e. Flussonic will not send data to the network while there is traffic in the multicast group. As soon as it is discovered that the main broadcaster has disappeared, we will start broadcasting, and as soon as he returns, we will stop.

WebRTC

Our WebRTC Player can publish video from a canvas element, giving you the ability to apply your own filters, logos and other dynamic data to the webcam image. For example, you can not limit yourself to “standard” OS filters, but apply your own “masks”.

We have also improved the mechanisms necessary for high-quality operation of WebRTC ABR: selecting the track from which to start playing, improved the NACK processing mechanism and enabled it by default for all clients.

SDI

At 22.12 we spent a lot of time working with professional equipment, this affected the support of Decklink, DekTec, and Magewell. We added support for new vendor SDKs and added Dolby Digital Audio capture.

Flussonic can not only capture audio and video from SDI sources, but also supports VBI/VANC, extracting both subtitles and teletext from any SD-SDI, HD-SDI sources. This data can also be sent to SDI, forming an SDI bridge between studios.
