Flussonic 26.03 Released: Track Filtering, SimulCrypt EMM, and Retroview Everywhere

We are pleased to announce Flussonic 26.03, bringing important updates across Media Server, Central, Watcher, Catena, and Catena SE. This release adds track filtering for HTTP clients, SimulCrypt EMM encryption, Retroview dashboards inside Catena and Watcher, and significant improvements to Watcher NVR management and Catena SE deployment.

Flussonic Media Server 26.03

Release date: March 6, 2026

Major features

Track filter for HTTP playback

New track_filter stream option filters unsupported tracks for HTTP playback clients (HLS, LL-HLS).
Supports maximum width, video format whitelist/blacklist, and matching by user-agent/headers.
Enables better compatibility and more efficient delivery for diverse client types.

SimulCrypt EMM

Implemented SimulCrypt encryption, EMM part, extending conditional access support for professional broadcast workflows.

UDP MPEG-TS ingest improvements

Improved UDP MPEG-TS ingest (SPTS and MPTS): added RTP packet detection.
Fixed handling of UDP packets with non-aligned TS payload (as sent by ffmpeg by default).
Both changes eliminate MPEG-TS decoding errors caused by these conditions.

Multicast in Kubernetes

Resolved multicast interruptions and timeouts in Kubernetes deployments using Multus CNI.
Setting the gateway to "0.0.0.0" in the multus network configuration ensures stable multicast delivery in containerized environments.

API transparency

New backup_error field in the video stream state API response.
Increases transparency of the emergency failover mechanism by indicating why a placeholder failed to start.

Retroview in Catena and Watcher

Infrastructure for opening Retroview dashboards inside Catena and Watcher.
New proxy service for Retroview dashboards.

DVB SimulCrypt telemetry

Added DVB SimulCrypt telemetry for monitoring conditional access systems.

RTSP timestamp sync

Extended wait_rtcp parameter for RTSP to ensure timestamp synchronization exclusively through SR packets.
New telemetry metric to detect camera time problems when the option is enabled.

Image build optimization

Image is split into layers: rarely changed components are isolated for better cache reuse and faster rebuilds.
