Flussonic Media Server v.25.04

🔎 Why Upgrade to 25.04?

✔ Smoother DVR operations with intelligent cleanup scheduling.

✔ Lower CPU & disk usage with Retroview and optimized DVR.

✔ Advanced camera analytics via Iris API for security systems.

✔ SDI changeover reliability with audio frame loss compensation.

✔ Better MPEG-TS & teletext handling for broadcast workflows.

Let's look into detail about all the changes!

Retroview Integration — Historical graphs have been moved from Pulse to Retroview, reducing CPU usage for metrics visualization (#19777).
Teledis Dashboard Upgrades — Track MPEG-TS errors (TEI & checksum), filter metrics by server, and correlate data with software versions (#47469, #48254, #48255).
New Server Stats Dashboard — Monitor traffic, scheduler load, and server health in real-time for faster diagnostics (#48782, #49212, #49166).

WHIP/WHEP Enhancements — Improved support for cross-domain playback (#49108).
Camera API for Episodes — Retrieve recordings and analytics from Iris cameras via API for centralized processing. Enables:
Security & Surveillance: Access motion-triggered clips and metadata for central monitoring.
Analytics: Send object detection and timestamp data to third-party platforms (#46095).
SDI Audio Resilience — During SDI changeovers, the system compensates for audio frame loss by inserting silence and tracking gaps. Critical for uninterrupted audio delivery during hardware failovers (#48209).

DVR Cleaning Optimization — The new cleaner intelligently distributes cleanup tasks across the entire retention window. Benefits include:
Elimination of disk usage spikes during maintenance
Reduced I/O contention with ongoing recordings
Smoother archive rotation for high-load systems (#22155)
MPEG-TS Muxer Refactor — Enhanced efficiency in configuration management (#41909).
KLV & Teletext Improvements — Better metadata and subtitle processing for MPEG-TS and DVB teletext streams (#47177, #46598).

Device address is now saved in OpenTelemetry for camera control API calls (#46189).
Scheduler load metrics are fully visible on the Server Stats dashboard (#49166).

Resolved telemetry transmission issues (#49513, #49487).
Improved Prometheus API stability when handling "no data" cases (#49518).
Stream graph links now correctly reference the selected server in dashboards (#49519).
Certain non-critical input errors have been downgraded to warnings, with clearer separation of error types and new warning graphs in Teledis (#49406).
Permissions issues on input monitoring and server stats dashboards have been fixed (#49410).
Dashboards now reliably show stream input details (#48219).
Stream restart counters are now tracked more accurately (#48625).
Improved statistics collection and telemetry system (#48623).

Fixed DVR clearing for On Motion archives (#49230).
Archive relayout is now consistent even under load on multiple nodes (#49260).
DVR now includes mappings between range start time and real time in iris-dvr (#49581).

Improved transcoder startup stability (#48787).
Fixed a crash that occurred when adding a new input with higher priority than the current one (#49310).
MPTS reader options now apply without restarting the input (#49391).
MPEG-TS reader now handles empty chunked responses correctly (#49392).
Stream relayout by labels works correctly when under pressure (#49260).
Validation for size parameter in transcoder configs has been improved (#49464).

Changed streamer healthcheck status structure for better readability (#48716).
Improved execution time for streams_list API (#49164).
Deprecated the failover_from field to avoid misrouting streams (#49454).
Fixed VisionPoint model saving (#49480).
Increased speed of config_external generation — changes now apply faster (#49688).
Central no longer creates vsaas auth_backend by default (#49857).
Disk Usage Prediction — The Central API now includes an estimated_disk_usage field to:
Forecast storage availability
Monitor write rates
Enable proactive resource planning (#48298)
Improved Central Labeling — Central schema now references Layouter labels in streamer and stream objects (#49567).

Agents now connect up to 10x faster — activation time reduced from 10 seconds to 1 second (#40801).
