vimacc OA - Release Notes

Upgrade information from installations earlier then 2.2.10.26

Based on the project experiences over the last decade, the internal runtime database of vimaccOA (named “vimacc Config”) has been general re-engineered for better runtime performance and system stability – also results in an overall improvement of the redundancy features of vimaccOA.

Reworking the IPC protocols of the “vimacc Config” harms, first time ever, the compatible with earlier versions of vimaccOA - NOT the compatible with any version of WinCC OA. Cause of this any upgrade of distributed vimaccOA installations, from versions earlier then 2.2.10.26, needs additional plannings to keep operations without any general downtime.

Please contact the WinCC OA VIDEO experts you trust for further information and support (keyword “vimacc ConfigNG”).

Upgrade information from installations earlier then 2.2.13.1

In preparation of an optimized memory management the internal structures of handling feature lists and license options has been improved for the 2.2.13.x release.

To keep backwards compatibility with current installations of WinCC OA VIDEO it’s important to set the following parameter in the AccVimaccRoot.conf on the vimacc Config-Servers.

[FeatureListEncoding]

Base64=false

Additional information regarding feature “Stream cloning”

The feature of “Stream cloning” (introduced in 2.2.10.30) needs an update of the internal feature lists in vimaccOA. Please contact support for further guidance for activation of this feature.

Changelog (compared to 2.2.10.37)

vimacc-Core

• Setup improved with new images giving information about the version to be installed.
• Internal protocol sockets optimized regarding reconnect handling.
• If more than 3 reconnects occur within 5 seconds, delay the next reconnect by 10 seconds. This not only reduces the load, but also guarantees that the 'Network Interruption' logo will eventually be displayed, which was not the case otherwise.
• Fix in Decoder classes for H.264, that ensures in addition to the SEI header, an AUD header can also appear in the stream before the SPS and PPS; This occurred with an AXIS M2036-LE bullet camera.
• Fixing issues in Config protocol in redundancy handling of AccVimaccConfigSlave and AccVimaccConfigProxy, which results in orphaned values in some cases.
• Fixed crash in AccVimaccWorkstation and AccVimaccDidplay when displaying decoded video frame (occurring under Debian 11 & Debian 12).

Changelog (compared to 2.2.10.30)

VideoOA EWO

• Fixed "leaking FrameBuffers" and "Flooding main thread with FrameBuffers" in vimaccAPI, which occures when using the RTSP streaming feature of the VideoEWO.
• Fixing digital zoom with mouse wheel for video panel items.

VideoManager

• Fixing some minor issues with Scenario and Sequences of type “VMS.
• Adding support for defaultRecording params, needed for orphaned ring adjustments.

• Adding support for ONVIF-Event activation, using the additional parameters "pullpointsubscription" or "eventsubscription".

vimacc-Core:

• Linux-Setups: Changing the install parameters of vimaccOA services, to improve start up handling. With old settings it happens, that the active Config Master degrades and the system switches in undefined behavior.
  • From: After=network.target
  • To:
    • After=network-online.target
    • Wants=network-online.target
• Fixing unimproved handling of background images in vimacc Workstation and vimacc Display, which impact to the decoding performance. Background images could be reenabled now in projects, where they has been disabled caused by this issue.
• Update of FFMPEG to version 4.2.9
• Fixed special handling in case of full decoder queue if RTP marker bit is not set on IDR FU-A End packet as observed with Bosch VIP X1 XF IVA encoder (fw ver. 28500572). Otherwise, no more data was passed to the decoder, effectively freezing the image.
• Fixing an issue of the RTSP session handling, where SETUP response might not have been processed because of premature state change.
• Fixing an issue of the RTSP session handling, where the selection of predefined trackID or codec name did not work.
• Some general improvements of the internal memory handling.

Additional information regarding new feature “Stream cloning”

The new feature of “Stream cloning” needs an update of the internal feature lists in vimaccOA. Please contact support for further guidance for activation of this feature.

New Features (compared to 2.2.10.29)

Introducing new feature of "Stream cloning", to be used on 2nd or 3rd video stream of a camera, to clone another stream of the same camera, internally in WinCC OA VIDEO.

Use case is for example, circumstances where it's better to receive only one stream from the source, but it's also needed to record it in two different ways.

LINUX: SecurityWizard Console-Mode (-c), no needs any longer for xhost-Mapping to root user. This is the default now in linux setups, which makes deployments to these systems much easier.

Changelog (compared to 2.2.10.29)

• VideoOA EWO

Fixed "leaking FrameBuffers" and "Flooding main thread with FrameBuffers" in vimaccAPI, which occures when using the RTSP streaming feature of the VideoEWO.

• VideoManager
  • Support for Parameter "ws_nonpresentstate", which allows to display cameras in the vimacc Workstation as "nonpresent", when the corresponding interface processes are offline (default "error").
  • Fixing scenarios for "VMS client", to generate the ID in vimacc without the ".link" part of the WinCC OA Datapoint.
  • Fixing scenarios for “VMS client”, to adopt them correct also if the lists only contain one entry.

Introducing new stream parameter "clone", to be used on 2nd or 3rd video stream of a camera, to clone another stream of the same camera, internally in WinCC OA VIDEO. Use case is for example, circumstances where it's better to receive only one stream from the source, but it's also needed to record it in two different ways.

Fixing Display-Dist support to create the cameras in vimaccOA without the dist name as prefix.

• vimacc-Core:
  • Adding functionality to use vimacc streams as source for streaming instances, e.g. to duplicate video streams in the vimacc interface, e.g. for use cases where it's better to receive only one stream from source, but it's also neede to record in two different ways.
  • SecurityWizard Console-Mode (-c), no needs any longer for xhost-Mapping to root user. This is also used in the linux setups.

Fixing mislead internal handling of controller definitions, which results in bad behavior during determination of the preffered controller for any instances.

This could result in the situation, that also with only one configured controller, no instance is requesting the mutex to get up and running.
