Flussonic's monthly release cycle has introduced critical features aimed at enterprise scalability and low-latency delivery. 1.1 Broadcast and Ingest Improvements

SMPTE ST 2110 & NMOS Integration: Full support for uncompressed IP video transport, allowing Flussonic to act as a bridge between traditional broadcast and OTT.

Track Filtering: Introduced in version 26.03, allowing granular control over which audio/video tracks are delivered during HTTP playback.

SimulCrypt EMM Support: Production-ready support for Conditional Access Systems (CAS) to enhance content protection. 1.2 Playback and Delivery

LL-HLS & WebRTC (WHEP): Implementation of Apple’s Low-Latency HLS and WebRTC-based playback ensures sub-second latency for live streaming.

HLS fMP4: Support for H.265 (HEVC) in browsers via fragmented MP4, reducing bandwidth requirements without sacrificing quality. 2. Flussonic Watcher: Surveillance and Analytics

Watcher has evolved into a high-density Video Management System (VMS) capable of managing thousands of cameras. flussonic release notes full

Vehicle Analytics: Advanced detection for vehicles, including those without license plates.

NVR Workflows: Enhanced management of Network Video Recorders, allowing for smoother archival playback and failover.

Redesigned Mosaic Experience: A modernized interface for multi-camera monitoring, introduced in version 26.04. 3. Infrastructure and Cloud Management

Flussonic has optimized its deployment for modern dev-ops environments.

Kubernetes Orchestration: Simplified deployment of Watcher and Central in cloud environments using native Kubernetes tools.

GPU-Aware Transcoding: Automated orchestration that intelligently assigns transcoding tasks based on available hardware acceleration.

Redis Data Persistence: Transitioned all in-memory data to Redis to improve platform stability and persistence during updates. 4. Key Technical Deprecations

To maintain a modern codebase, Flussonic has phased out legacy technologies:

Intel Quick Sync (QSV): Deprecated in favor of more robust GPU-accelerated alternatives. This paper summarizes the major updates and evolutionary

Cluster RTSP 302 Redirect: Removed to streamline modern routing protocols. 5. Summary Table: Recent Version Highlights Release Date Key Feature Highlights 26.04 April 9, 2026

The Flussonic release notes provide a detailed history of the platform's evolution, covering critical updates to its Media Server, Central management, and Watcher surveillance systems. Staying current with these notes is essential for maintaining a high-performance video streaming or surveillance infrastructure. Recent Major Releases (2026)

The 2026 update cycle has focused heavily on infrastructure modernization, security, and enhanced video surveillance workflows.

Version 26.04 (April 2026): This release prioritized video surveillance improvements, introducing QR code logins and richer access logs. A key highlight is the redesigned "mosaic" experience and more resilient NVR (Network Video Recorder) workflows that switch recording to healthy servers immediately if a disk fails.

Version 26.03 (March 2026): Introduced track filtering for HTTP playback and support for SimulCrypt EMM. It also integrated Retroview dashboards directly into Catena and Watcher for better analytics.

Version 26.02 (February 2026): A milestone for broadcast standards, adding full SMPTE 2110 integration with NMOS control. This version also made SimulCrypt CAS support production-ready and improved Kubernetes deployments with prefix-based routing.

Version 26.01 (January 2026): Focused on low-level performance, including Decklink 8K Pro card support and improved stability for 4K SDI delivery. Key Feature Milestones (2025) Fix: VA-API hardware transcoding memory leak on Intel

Throughout 2025, Flussonic introduced advanced telemetry and playback optimizations. Blog - Flussonic Streaming Solutions

22.14.0 (December 2022 – Last of 22 series)

• Fix: VA-API hardware transcoding memory leak on Intel Xe GPUs.
• Feature: stream stats API now returns total_billable_seconds (for usage billing).
• Deprecation: Flash RTMPE support removed.

Known Issue in 22.x: LL-HLS requires strict PTS ordering; out-of-order frames cause infinite buffering on iOS 16.

Flussonic 22.07.3 (2022-07-29)

- [httpclient] increase default timeout to 15 seconds
- [srt] fix handling of epoll events in srt_mux
- [hls] proper discontinuity when codec changes mid-stream
- [dvr] add fsync after each segment to prevent corruption on power loss
