Changelog

Ingest 7.0.0

• New metrics are available for the Ingest streamconnections in the REST API that can be used to monitor the streams.
• Fixed bug where the Ingest would crash with a std::runtime_error if grabbing a thumbnail on hardware without an Intel CPU with integrated GPU.
• Improved error messages for encoders and sources.
• Missing fields in the REST API for the Ingests have been added, such as max_network_latency_ms for streamconnections.
• Logs are now automatically flushed every 5 seconds.
• The class StaticIngestSystemController has been removed, please use the SystemControllerConnection class and the system controller instead.

Production Pipeline 8.0.0

• New metrics are available for the Pipeline streamconnections and Output in the REST API that can be used to monitor the streams.
• Fixed the AUD format in MEPG-TS output of the Pipelines when using HEVC, which earlier caused clicks in the audio channel and a lot of Invalid NAL unit 4, skipping. errors when playing back the streams using ffmpeg.
• Support for labels (so-called “Under Monitor Display”, UMD) in the multi-view outputs. The labels are set through the REST API when setting up multi-view outputs and can be changed at runtime.
• Missing fields in the REST API for the Pipelines have been added, such as max_network_latency_ms, alignment_ms and convert_color_range for streamconnections.
• Fixed DTS calculation for output streams in both the Multi-view generator and Output components.
• The network connections between a ControlDataReceiver and other ControlDataReceivers are now using TCP as protocol instead of SRT, which means that the messages are delivered as soon as they arrive and that no control messages will be dropped due to to timeouts in the transport.
• Fixed a minor CUDA memory leak in the multi-view generator that caused a slow, constantly growing GPU memory usage.
• Fixed CUDA memory corruption sometimes occurring when stopping and quickly restarting a multi-view output.
• Nvidia Ampere GPUs are now working with older CUDA drivers than version 510.
• Logs are now automatically flushed every 5 seconds.
• The classes StaticMediaReceiverSystemController and StaticMediaStreamerSystemController have been removed, please use the SystemControllerConnection class and the system controller instead.

Control Data Sender 7.0.0 and Control Data Receiver 8.0.0

• The network connections between a ControlDataSender and ControlDataReceivers are now using TCP as protocol instead of SRT, which means that the messages are delivered as soon as they arrive and that no control messages will be dropped due to timeouts in the transport.
• The classes StaticControlDataSenderSystemController and StaticControlDataReceiverSystemController have been removed, please use the SystemControllerConnection class and the System Controller instead.

System Controller 1.0.0

• Support for setting CORS and custom HTTP response headers in the configuration file.
• Improved validation of HTTP request payloads and improved error messages.
• New endpoint for deleting any type of component, [DELETE] /component.
• New, built-in Prometheus exporter, accessible through endpoint at [GET] /metrics.
• The version of the running system controller is now returned in each HTTP response in the X-Binary-Version header.

Known limitations

GPU performance

The GPU utilization in the Ingest status message is currently not working. Use intel_gpu_top and/or nvidia-smi instead.

Drivers

You need to install the CUDA Toolkit on Ingest machines, even if they don’t have Nvidia cards.

MPEG-TS output

The timestamps in the MPEG-TS output are not equidistant, which might confuse some playback tools. Playback the stream using a tool that works for now, such as ffmpeg.

Pre-shared key

The pre-shared key used to authorize components in the System controller is currently hard-coded into the Ingest application. This means that the psk in the System controller’s example config file must be used, otherwise is it not possible to connect an Ingest to the system.
