Introduction

Notch utilises a number of 3rd party SDKs that require the installation of such SDKs and/or DLLs onto the media server that is going to be used for your project. below is a list of those sdks, and a list of the dlls and where they need to go.

SDKs that may require installation:

If you use any of these features, you will need to install the appropriate SDK on your media server.

SDK Used For
NVIDIA AR Broadcast NVIDIA Body Tracking and NVIDIA Face Tracking
NVIDIA Video Effects NVIDIA Virtual Background
Kinect 1 Drivers v1.8
Kinect 1 SDK v1.8
Kinect 1 support
Kinect 2 Drivers Kinect 2 support
Kinect 4 SDK
Kinect 4 Body Tracking SDK
Kinect 4 Azure support
Intel Realsense SDK V2.0 Intel Realsense support

DLLs that may require copying:

Notch Builder and Standalones automatically have these DLLs in place. However, when running Notch Blocks in a media server, you may need to copy the specific DLL on to the media server into a specific location. These can all be found in the program files notch directory, in C:\Program Files\Notch, where they can then be copy / pasted to wherever they are needed.

Media Server File Path
Ai C:\Avolites\Ai\Distrib
Disguise C:\Program Files\d3 Production Suite\build\msvc
Green Hippo C:\Program Files\GreenHippo\HippotizerV4\bin
Pixera C:\Program Files\AV Stumpfl\Pixera\build_X-X-XX
Touch Designer C:\Program Files\Derivative\TouchDesigner\bin
Others Refer to your media server

Troubleshooting

Failure to load Notch blocks:

For systems that do not have Notch Builder installed, Notch blocks may fail to load in FXPlayerHost as well as the media server. If this is the case then try setting the following registry key manually:

Key Path: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WIBU-SYSTEMS\CodeMeter\Server\CurrentVersion
Key Name: ShmTimeout
Key Value: 10 (0xa hex)
Key Type: REG_DWORD

or by running the following command in a Command Prompt with Administrator privileges:

REG ADD HKEY_LOCAL_MACHINE\SOFTWARE\WIBU-SYSTEMS\CodeMeter\Server\CurrentVersion /v ShmTimeout /t REG_DWORD /d 0xa
