WIBU-based Licensing System

This chapter describes management and usage of the licensing system based on CodeMeter from WIBU Systems available in Viz Engine 3.10 and later. It replaces the previous VALID/Sentinel/Hardlock Dongle licensing system and allows Viz Engine to be used without a physical dongle on each machine, by allocating licenses from a license server on the network.

This section contains the following information:

Important Pre-installation Information

The WIBU licensing system requires the installation of the CodeMeter Runtime Software (included in the Bundle installer):

WIBU Runtime

Viz Engine Version

7.60a

5.1 or newer

7.40

4.4.1, 5.0

7.21a

4.3

7.20

4.1

6.80

3.12.1

6.60a

3.10.0 - 3.12.0

When the license should be retrieved from a dedicated license server, it must be configured in the Vizrt Licensing Service (see Client Configuration page in the License Server Setup and Administration section of the Vizrt Licensing Administrator Guide) or the CodeMeter WebAdmin.

Information: There is an auto discovery if no license server is configured in the server search list of CodeMeter.

Information: On network disconnect and reconnect, it may happen that a license is checked out twice. In this case, it must be released manually on the CodeMeter service on the license server or the license server can be restarted.

Note: Prior to upgrading any version it is highly recommended to create a backup of the Viz Engine configuration files located in: %PROGRAMDATA%\vizrt\VizEngine.

Key Features and Workflow of the New Licensing System

  • images/s/-29r3su/8804/xgjkrn/_/images/icons/emoticons/warning.svg The VALID/Sentinel/Hardlock Dongle is no longer supported for Viz Engine 4.0.0 and later versions.

  • Dongle-less operation on clients with monitoring and logging capabilities.

  • Grace periods for allocated licenses to avoid immediate expiration on network or service interruptions.

    • In Viz Engine 4.0.0/3.14.1 or newer license errors are logged to the Graphic Hub journal (see here how to enable E-Mails).

      • Logs license errors (any grace state or if expired) to the Graphic Hub journal as dedicated log messages with level 820.

      • Logs warnings two weeks and every hour prior to license expiration as dedicated Graphic Hub journal message with level 920.

  • Configurable WIBU license container location (any local container, any network container or a dedicated container).

  • Configurable licenses to consume.

  • Viz Artist/Viz Engine startup was changed and no startup helpers are needed anymore (.cmd files, started executables).

  • When a core license cannot be allocated on startup Viz Engine starts in configuration mode.

  • When an additional license fails to allocate on startup an error is logged and the required feature keeps disabled on startup.

Limitations and Known Issues

  • All additional licenses consumable to a core license must come from the same container as the core license.

  • images/s/-29r3su/8804/xgjkrn/_/images/icons/emoticons/warning.svg Matrox DSX.Core installer corrupts an existing CodeMeter Runtime installation and causes a crash on Viz Engine startup.

    • Uninstall any CodeMeter Runtime prior to installing Matrox DSX.Core. Install DSX.Core and afterwards install Viz Engine and the newer CodeMeter Runtime.

  • For a preview in TRIO and Pilot as Engine Core, a DVI OUT license is needed.

  • Configuration of licenses requires to start Viz Engine in configuration mode with the configuration UI.

  • In Viz Engine 3.12.1 and newer, the configuration UI works without a valid license and can be configured through the configuration UI.

    • In Viz Engine 3.12.0 and older, the configuration UI only works with a valid license, which depends on the configuration. If no proper license is available then a manual edit of the corresponding configuration entries is required. See Configuration Entries in the Viz Engine Configuration File.

    • By default, the WIBU licensing system with Engine Core license (ENG_ENG_CORE) is used when no configuration exists.

  • File-based local WIBU licenses on server operating systems (terminal server) cannot be used via remote desktop connections. For example, if you have installed Windows 10 the access via remote desktop connection works but not, for example, with a Windows Server 2016 system.

  • Viz Engine Startup may take long when network communication has high latency or bandwidth is limited. Workaround for now is to use a license server on a local network.

Basic Set-up

To set up Viz Artist/Viz Engine licensing with WIBU or VALID/Sentinel/Hardlock:

  1. Install Viz Artist/Viz Engine with the bundle installer (see Viz Artist and Engine Installation).

  2. Configure CodeMeter with the Vizrt Licensing Service or the CodeMeter WebAdmin (can be opened from the CodeMeter Control Center).

  3. Configure the license system in Viz Engine by starting in configuration mode and navigate to Viz Licenses.
    images/download/attachments/114325611/image-2023-8-7_10-27-14.png

    1. When using any WIBU network container (license server):

      1. Open the CodeMeter WebAdmin and add the license server to the server search list:

        images/download/attachments/114325611/image2022-8-12_11-47-53.png
      2. In the configuration UI under Viz Licenses set Container to 0,0 Any Network Container or in the Viz Engine configuration file set License_Containers = 0,0,1.

      3. Configure the core license and any additional licenses. In the configuration UI under Viz Licenses configure Core License and Additional Licenses or in the Viz Engine configuration file configure License_Core and Additional_Licenses.

    2. When using any local WIBU container (dongle, file):

      1. In the configuration UI under Viz Licenses set License Location to 0,0 Any Local Container or in the Viz Engine configuration file set License_Containers = 0,0,0

      2. Configure the core license and any additional licenses. In the configuration UI under Viz Licenses configure Core License and Additional Licensesor in the Viz Engine configuration file configure License_Core and Additional_Licenses.

    3. When using a dedicated WIBU container (with full container identifier):

      1. In the configuration UI under Viz Licenses, set License Location to a specific container (for example, 130,3910158968 Network license) or in the Viz Engine configuration file set License_Containers = 13 0,3910158968,1

      2. Configure the core license and any additional licenses. In the configuration UI under Viz Licenses configure Core License and Additional Licenses or in the Viz Engine configuration file configure License_Core and Additional_Licenses.

  4. Start Viz Engine.

Configuration Settings

Why Do We Need to Configure the Licenses?

  • Prevent license theft by instances on other nodes or instances on the same node. Licenses are in one container and have a count.

  • Several licenses may enable the same feature. There is no one to one mapping of application feature to a single license possible. For example, with multiple instances on one node (Trio One Box), it is important which instance consumes which license for proper operation (first needs SDI OUT, SDI IN and 2nd DVI HD).

  • A license may enable multiple internal application features.

Configuring the License System in the Viz Engine Configuration UI

See Viz License Configuration.

Note: By default, the WIBU licensing system with Engine Core license (ENG_ENG_CORE) is used when no configuration exists. When no such license is available the configuration file must be edited. See Configuration Entries in the Viz Engine Configuration File.

Note: Configuration of the combination feature requires that no instance is running on the machine that already allocated a combination feature, else no information can be retrieved and it cannot be configured (due to the access mode of this licenses).

Configuration Entries in the Viz Engine Configuration File

Entries changed in 4.0.0 and later: Legacy_Licensing (removed), License_Location (removed, was replaced by License_Containers)

  • License_Containers: WIBU license source. Determines where WIBU should search for license containers and allocate licenses from.

    • Can be set to one of the following values:

      • 0,0,0 - Any Local container. Searches exclusively for containers located on the same PC or allocated to the same VM (for example, dongle, file).

      • 0,0,1 - Any Network container. License is to be sought in the network (LAN, WAN), CodeMeter License Server activated as network server or CmWAN.

      • X,Y,1 - A dedicated container, where X is the container mask (for example, 130) and Y is the container serial (for example, 3910158968)

    • Default: 0,0,1

  • License_Core: WIBU core license, which determines also the available additional licenses.

    • For WIBU license details, see WIBU Licenses and their effect.

    • Can be set to one of the following values:

      • ENG_ENG_CORE - Engine Core

      • ENG_PRV_CORE - Preview Core

      • ART_ARTIST_FREE - Free Viz Artist

    • and for OEM (see Note on Shared Licenses)

      • VIZLIB_LIBERO_CORE - Viz Libero Core

      • VIZARE_VIZARENA_CORE - Viz Arena Camera Tracking Engine

      • VIZECL_VIZECLIPSE_CORE - Viz Eclipse Core

  • Additional_Licenses: WIBU additional licenses that are additionally consumed and determined by the core license.

    • For WIBU license details, see WIBU Licenses and their effect.

      Note: When a license is configured it is consumed, even when it has no effect. If licenses are configured that are not allowed, an error is logged on startup.

WIBU License System

Summary of Key Concepts in the Licensing System

  • Core- and additional licenses exist.

  • OUT based channel counting for NDI/SDI/IP

  • IN and OUT channels are resolution independent up to 3G HD

    • <=2K size of render output

  • Preview channels (preview/clean feed OUT) are co-enabled with every OUT channel license.

  • MezzIP applies to all compressed streams:

    • Included: RTP/UDP/WebRTC

    • Excluded (requires SDI/IP licenses): SMTPE ST2022-06, ST2022-07, ST2110; ASPEN.

  • Multiple licenses may enable the same application feature!

  • Licenses are consumed by multiple processes and license share mode influences possible consumption (see WIBU license share status).

WIBU License Share Status

Refers to a WIBU license and how its usage is counted when it is allocated/consumed.

  • Exclusive: Allocation can only be performed once on a node (=machine).

  • User Limit: Each allocation is counted, independent of instance and node.

  • Shared: Each allocation is counted once per node. Multiple allocations on the same node allocate only a single license.

  • No User Limit: Only checked for existence, no counting is performed.

  • Configure e-mail sending in Graphic Hub Terminal Options E-Mail settings.

  • Configure e-mail addresses and notification options for specific alerts in Graphic Hub Manager Alert settings.

  • Viz Engine directly logs to the Journal of the connected Graphic Hub and triggers e-mail messages for the following alert levels:

    • Level 820: Viz Engine WARNING: License, Warnings reported by Viz Engine related to licensing.

    • Level 920: Viz Engine ERROR: License, Errors reported by Viz Engine related to licensing.

Setup Redundancy for a WIBU License Server

Setting up WIBU license server redundancy is described below. See License Server Redundancy in the Vizrt Licensing Administrator Guide for additional details.

Note: The grace period for acquired licenses is 72 hours if the license is lost to recover possible network issues or the license server.

Set Up Redundancy for a WIBU License Server

  1. Make sure two hosts (A & B) have VizrtLicensingInstaller.exe installed and select use as network license server during installation. See License Server Activation in the Vizrt Licensing Administrator Guide.

  2. Connect one WIBU dongle to 'A' and import a key with licenses.

  3. From WIBU web admin UI of 'A', make sure the container exist and all the added features are listed.

  4. On the client configure 'A' as first license server, and 'B' as second one (in the search list of the local CodeMeter web admin).

Test License Server Failover

  1. Set the license configuration in Viz Engine.

  2. Start Viz Engine.

  3. From CodeMeter web admin UI of 'A', verify that the licenses are allocated and used by the client.

  4. Disconnect the network cable of 'A' or shut down the machine.

  5. Wait until the Viz Engine(s) starts writing 'License Server not found..' and the grace status for the configured features is 'grace_state=2/VL_GRACE_GRACE, '.

  6. Move the WIBU dongle from 'A' to 'B'.

  7. Viz Engine recovers and re-obtains the license from 'B'.

Recover First License Server

  1. Recover license server ‘A’.

  2. Disconnected the failover license server from network or shut it down.

  3. Waited until the Viz Engine(s) enter grace period.

  4. Moved WIBU dongle back to the original license server ‘A’.

  5. Viz Engine recovers and re-obtains the license from 'A'.

Notes

  • The license must be in the same container to recover. A second license server with a different container does not work.

  • Not started Viz Engines which are configured the same, can start and obtain the license from 'B'.

  • An arbitrary number of servers can be added to the server search list of CodeMeter, even when Viz Engine is running. It is possible to add a failover server after the original license server failed.
