25.01 Media Server

The January release introduces enhanced features for professional ad management. You can now add SCTE markers to raw video streams with frame-level precision, ensuring seamless scene transitions for viewers. Use genlock for Dektec SDI cards, which can now be enabled in Flussonic settings. Plus, no more lost video surveillance archives due to connection interruptions. Cameras with Iris firmware can automatically recover missing archive fragments when the connection to the server is restored.

Add SCTE Markers to Raw Video Streams with Frame-Level Precision

Previously, Media Server could only generate SCTE markers for encoded video. By default, the marker would align with the nearest keyframe, which could result in an unpleasant viewing experience, such as an ad interrupting a dialogue or an action-packed scene in a movie.

In the new version, we have enabled frame-level precision marker placement in raw video streams. Now, when receiving SDI from a source, you can use the API to add markers with precise frame-level control. Your ads will appear exactly when planned.

This feature helps reduce the number of tools needed for broadcasting and saves resources on manual ad management. To enable marker insertion into SDI, contact your account manager.

Maintain Stable GOP Length Even with SCTE Markers

One of Flussonic’s key transcoder features is generating streams with consistent Group of Pictures (GOP) lengths, ensuring IDR frames appear at predictable intervals.

However, ad insertion could disrupt this. When an SCTE marker is added to a video stream, it might “break” the GOP structure by altering the number of frames in a group and creating a new IDR frame.

For example, if the GOP length is 28 and an SCTE marker is inserted at the 10th frame, the 11th frame would become an IDR frame, starting a new 28-frame GOP. This disrupts segment duration and can lead to playback errors in DASH.

In the new version, we have resolved this issue. GOP length now remains consistent, even when an SCTE marker appears mid-sequence.

Recover Lost Archive Fragments with Iris Firmware for Cameras

In video surveillance, it is common to encounter situations where part of the footage from cameras is lost. This can happen due to network issues, camera disconnections, or video server restarts.

Such incidents result in missing archive segments, reducing the system’s reliability and creating security risks.

Cameras with Iris firmware help prevent these losses. When the connection is restored, they automatically upload missing fragments to the archive. Even if a segment was absent in the live stream, you’ll get a complete recording in the archive — down to the last frame.

Use Genlock for Synchronizing Signals on Dektec SDI

We have added support for genlock on Dektec SDI capture cards, ensuring high-quality video with precise signal synchronization. To enable this feature, activate Genlock support in the Flussonic settings.

Manage Network Settings on Flussonic Appliances Without Server Access

Our appliances (Coder, Lutra, and others) now include a dedicated port for managing network settings. This allows you to adjust network configurations even if the server is inaccessible.

We also recommend backing up the configuration file to a USB drive with login credentials to avoid losing access to the server in any situation.

Optimize DVR Reading with Flussonic

In version 25.01, we have optimized reading MBR archives. Previously, when requesting a multi-bitrate stream, Flussonic would retrieve all tracks and then select the required bitrate.

We have reworked this logic to eliminate redundant processes. Now, you will get the desired track immediately, reducing disk load.
