23.12 Media Server​

23.12 release notes of Flussonic Media Server introduces features like ad insertion with SCTE-35 markers via API method, DRMtoday integration, administrative tools and other enhancements. Additionally, it includes optimizations, bug fixes, and documentation updates for better performance and user experience.

SCTE-35 markers​

For independent ad insertion. API method was implemented, so that SCTE-35 markers are integrated into ad windows.
Flussonic API
To make it easier to keep track of where streams are pushed when pushed to multiple locations, the parameter for a text comment was added to describe a push or an input.
Integration with DRMtoday
To access advanced DRM capabilities, including encryption and expand content protection, Flussonic Media Server is integrated with DRMtoday. To use DRMtoday with Flussonic, learn how to configure the CPIX DRM here: flussonic.com
Integrating EIT data into MPTS
When using EIT-generators or receiving EITs in incoming streams, we added an ability to copy EITs from the input stream without any changes, as an alternative data integration method.
Logos in Flussonic Coder
Users can add logos to incoming streams or customise video content with them in Flussonic Coder.

Admin UI​

To let our users leave human-readable comments to streams and pushers and simplify the admin work, the field for text comment about push or an input was added. The field provides information on where streams come from and where they are sent when the config grows.

CMAF protocol​

To let our customers use CMAF on the same level as all other protocols, we made it be a part of the protocol list enabled by deafult.

Our own SRT implementation​

We implemented our default SRT for all streams to:

• Get config right when the connection is established
• Store the config data for each source in an external database
• Receive reliability and additional speed-of-service capabilities

Archive download​

We resolved an issue with interrupted archive downloading via the Agent proxy when the connection between Flussonic and Agent is slow.
Flussonic RAID
We increased the performance of Flussonic RAID storage by allocating its storage resources for streams in batches.
For quicker cleanup operations in Flussonic RAID, we improved the archive cleanup mechanism.

Bugs fixed​

Fragment export
We fixed issues with autocorrecting when setting start and end time of an exported fragment. The new DVR Player interface also provides improved timeline markers for the exported fragment.

Deleting deprecated fields
To maintain system health, we deleted deprecated fields ‘since’ and ‘last_error’ from the push stats.

API option to play MPTS over HTTP
An older and unsupported API option that allowed for playing MPTS streams over HTTP was removed. It was primarily used for debugging purposes.

Supporting MP2A encoded tracks
To play non-Apple-standard streams over HLS, audio tracks are correctly packaged into multi-language HLS streams (/video.m3u8).

Retroview statistics
Retroview statistics service performance was improved, for more details refer to: flussonic.com

Stream ingest
We fixed the issues with audio track drops and transcoder reconfiguration when streams are ingested with lots of DVB subtitle tracks. With this fix we ensure that DTS for audio does not break and streams keep on playing.

UDP push streams
We resolved an issue when UDP push streams experienced interruptions during “source_timeout” periods, even when a backup source was available and running.

Stream restart at ad insertion
The streaming process no longer restarts when advertisements are being inserted into a stream.

SRT protocol implementation
The ‘libsrt’ implementation of an SRT protocol is available via the ‘srt1://’ URL scheme, providing stability of Flussonic Media Server and avoiding overload of transcoder and video freeze.

Playing HLS after restreaming
There is a compatibility issue in HLS streaming resolved. With this fix players are capable to play content after restreaming in a correct ISO 639-2 alpha3 format (instead of an iISO 639-1 alpha2 format used before).

DVR player
The issue related to audio track switching during DVR playback mode was resolved. Users no longer need to click the green area of the timeline for audio track switching and prevents short-time switching. There is no duplication of the preview frames displayed instead of one, when selecting the exported interval in a desktop browser. The preview frames no longer display too far when hovering over the timeline.

Since 23.12 if ‘protocols’ option is specified in the config, the playback starts DVR Player in the Admin UI as intended. Mute option is now supported for WebRTC playback on the embed.html page.

Flussonic API
To be able to get disc information using Openmetrics with Flussonic, we fixed an issue with disk I/O metrics missing in the response to GET /config. The io_util parameter is returned among other information about disks on the server.

We reduced packet loss with the improved calculation of a NACK interval in SRT implementation.

A properly described peer authorization error appears in response to GET /config when peers are added in Media Server config, instead of an HTTP 500 error.

Let’s Encrypt certificates
Let’s Encrypt certificates are now properly issued and renewed via Flussonic Admin UI.

SHOUTcast ingest over HTTPS
By ensuring compatibility with Erlang 26, Flussonic Media Server now effectively handles SHOUTcast streams over HTTPS.

RTMP URL ingest
RTMP URLs with an empty application name are now ingested in the correct way.

Memory leaks and ‘thumbnails’ option
We resolved an issue with memory leaks occurring when the ‘thumbnails’ option was enabled for numerous streams.

MPEG-TS ingest
MPEG-TS ingest over UDP no longer crashes when there are any changes to the input options made.

DVB subtitles
DVB subtitles are now correctly converted to the WebVTT format during SRT ingest, improving compatibility and compliance with web-based video standards.

Stability of transcoder
We improved stability and reliability of a transcoder when working with specific types of MPEG-TS sources.

Admin UI
To remove excessive operations that caused errors, we fixed Flussonic update procedure initiated by clicking a button in Admin UI.

SRT pusher
We resolved an issue where the SRT pusher in the SRT implementation was not sending the Stream ID extension correctly when using the push srt2:// command or configuration.

RTMP publications
For a stable operation of RTMP publications when using ‘config_external’, there is no unexpected termination with the ‘reached_max_restart_intensity’ reason.
