Client Area

New

#5233 (Flussonic) Added the multilanguage HLS ingest. Use input hls2:// for an HLS stream with several audio tracks packed as separate media playlists (EXT-X-MEDIA).
#14478 (Flussonic) Added the new parameters for fine-tuning the input switching: audio_timeout, video_timeout, and max_retry_timeout. They allow switching between inputs if there is no video or audio data in the stream.
#31793 (Flussonic) Added the support for HbbTV pass-through in Flussonic multiplexer. Also, you can add a HbbTV data from another source to a program when composing the multiplexer but it requires complex settings: please contact our support team for help.

Fixed

#22640 (API) Added the api_call_event event for debugging or analyzing incidents involving API requests.
#34656 (Flussonic) Fixed the long timeout for DASH playback request for a dead restreamed stream. This resulted in about 60 seconds black screen on the client side before indicating the problem.

#39275 (Flussonic) Fixed the multiplexer crashes if other option referred to a multiplexer with service_type none and ts_stream_id configured in one of the programs.
#39292 (Flussonic) Fixed the issue that the output bitrate was twice as high as that specified in the settings when preparing the CBR SPTS.
#39490 (Flussonic) Fixed the issue with NVENC segmentation faults when open session limit is reached. Flussonic now handles this situation correctly by logging a relevant error without failures.

Flussonic Central 24.01 is an update, featuring Long Polling for faster episode delivery, streamlined camera connection with Assigning Agents, enhanced scalability through streamlined streamer deployment, optimized face fingerprint handling, improved distribution of episodes for superior video analytics tasks and many more. Explore the new possibilities of Flussonic Central in the freshest release notes 24.01.

New

#31270 Enhanced the delivery of episodes to Watcher or other client application by using the Long Polling technique. This will help decrease the delay when using episodes for access control like opening door by a recognized face or opening gates by a recognized license plate.
#35196 Assigning Agent with a streampoint is made independable from the layouter to allow the camera connection even if the layouter is unavailable.
#35671 Supported the /central/api/v3/ API path along with the /streamer/api/v3/ to distinguish the services installed on the same server without configuring different ports.
#35918 Implemented the storing of updated_at in the Central’s database to avoid possible desynchronization and episode loss.
#36132 Added the ability to disable provisioning of configuration from Central to streamers. It is useful when you deploy your streamers in Kubernetes or other orchestration system. Set CLUSTER_NODE_CONFIG_PROVISION_ENABLED = false to use this feature.

Improved

#35259 Improved the distribution of episodes between the analytics nodes to allow Central push episodes batches for identification. This increases control over the results of episodes processing on the analytics nodes and provideы means for handling any errors that may be encountered during the episodes processing.
#35377 Improved the check for episode validity to forbid episodes with updated_at=0 and started_at=0 because such values do not make sense and may prevent validation by other services.
#35395 Improved the face fingerprint handling in Central to exclude merging data and utilize only the relevant data returned by the analytics nodes. This improvement increases the system performance.
#35402 Improved the validation of returned person list to exclude persons with invalid photos.
#35515 Renamed the name parameter to media to avoid confusion and highlight that the parameter has the same meaning as in GET /episodes.
#35597 Improved the episodes fetching from Vision Inference by implementing the polling technique to reduce the delay between the episode start and its appearance in Central.
#35617 Renamed vision role to inference to reflect that this role corresponds to vision-inference package.
#35696 Updated the config_external and central_event_collector URLs to use /central prefix instead of /streamer.
#36008 Default HTTP timeouts increased up to 60 seconds to improve Central operation in Watcher software package.
#36009 Removed the event sinks enabled/disabled setting because there is no need in disabling it.
#36040 Increased the system security by removing the password and API key generation when installing Central as part of Watcher software package. The users shall set the password themselves in order to use Central Admin UI.
#36044 Removed the SINGLE_INSTALLATION config parameter to facilitate scaling.
#36154 Central’s default port is now 9019.

Fixed

#35249 Fixed the issue with GET /episodes request with filter by updated_at returning not all the detections present in the database because the updated_at value was processed by Central in a wrong way.
#35265 Fixed the issue with streams moved to another streamer at failover not returning to the streamer specified in their settings after that streamer has restored after failure.
#35501 Fixed the issue with Central continuing to provision a stream to analytics nodes after vision is disabled on the stream.
#35571 Fixed the issue with updated_atsynchronization ensuring its uniqueness for every episode.
#35610 Fixed the issue with updated_at value not updated for the episodes received from the analytics nodes.
#35684 Fixed the issue with the streams having vision enabled not allocated to inference nodes.
#35922 Fixed the issue with scheme parameter not applied when executing GET /streams request.
#35923 Fixed the issue with analytics not working if cluster_key is not specified in Central which is wrong because cluster_key is not required for analytics nodes.
#36026 Fixed the issue with Agent statuses incorrectly probed by Central leading to incorrect expectations of the Agent allocation to streamers.
