Flussonic Media Server 22.12
December 1, 2022
Flussonic Media Server 22.12 has been released.
The headline of this release is support for AV-1 hardware encoding. Save traffic with AV-1: Flussonic supports AV-1 both on the input and on the output.
You will need NVIDIA Ada Lovelace or later generation cards to use this feature.
Intel QSV changes are aimed at enhancing the visible outcomes: improved crop and deinterlace filters make the video look smoother after the transcoding.
config_external option is now available not only as an environment variable but also as an option in the
flussonic.conf configuration file. Be sure to check out the documentation to learn how to set up Flussonic to work with an external configuration system if you have a large cluster of servers to manage, or simply have a large number of dynamic streams.
SCTE-35 markers are now available for DASH manifests so you can insert ads to the player just like with HLS.
The capture of SCTE-35 from MPEG-TS sources is now enabled by default, no manual settings required. Ad markers are automatically accepted from any MPEG-TS source: UDP ingest, SRT publishing, HTTP MPEG-TS recapture.
Introducing a new option allowing the UDP MPEG-TS broadcasting in standby mode: the backup Flussonic will not send data to the network while there is traffic in the multicast group.
As soon as the main server fails to broadcast for some reason, the backup server starts broadcasting; when the main server returns, the backup stops.
Our WebRTC Player can now publish video from the
canvas element giving you the ability to apply your own filters, logos, and other dynamic data to the webcam image. For example, you can go beyond standard OS filters and apply your own masks.
We have also improved the mechanisms necessary for the WebRTC ABR quality: changed the way of choosing the track to start playing from, improved the NACK processing mechanism and enabled it by default for all clients.
In 22.12 release, we devoted a lot of time to the professional equipment including improvements for our support of Decklink, DekTec, and Magewell. We have integrated with new SDK vendors and added Dolby Digital Audio capture.
Alongside with capturing audio and video from SDI sources, Flussonic also supports VBI/VANC, extracting both subtitles and teletext from any SD-SDI or HD-SDI source.
The same data can also be sent to SDI to form an SDI bridge between studios.
