Spectator View

Spectator View is an augmented reality product that enables viewing HoloLens experiences from secondary devices. Spectator View has multiple configurations and supports a variety of scenarios from filming quick prototypes to producing keynote demos.

Samples

The Spectator View repository contains multiple sample projects. To see how to set up samples go here. To add Spectator View to your own project, see below.

Getting started with your own project

Obtaining the code

To build the Microsoft.MixedReality.SpectatorView Unity package, you will need the following:

1. Windows PC
2. Visual Studio 2019 installed on the PC
   • Universal Windows Platform development tools (installed through visual studio installer)
   • Desktop development with C++ tools (installed through visual studio installer)
3. Windows 10 SDK (10.0.18362.0)
4. Git installed on the PC and added to your PATH variable
5. NuGet installed on the PC and added to your PATH variable

Grab external dependencies (optional)

The below dependencies are optional but should be obtained if they are desired for video camera filming.

1. Download the Azure Kinect Sensor SDK
2. Download the Azure Kinect Body Tracking SDK
3. Download Blackmagic design's Desktop Video & Desktop Video SDK from here
   • Search for Desktop Video & Desktop Video SDK in "Latest Downloads" (Note: 10.9.11 is the current version used in the SpectatorView.Compositor.dll. Newer versions may contain breaks.)
   • Extract downloaded content to a external\Blackmagic DeckLink SDK 10.9.11 (make sure this path matches the path found in )

There are currently two ways to consume the com.microsoft.mixedreality.spectatorview.* Unity package. You can either build the package and generate a folder containing all project content to share with your team or you can add the MixedReality-SpectatorView codebase as a submodule to your project.

Build a package to share with your team

1. Clone the MixedReality-SpectatorView repository.
2. Checkout your desired branch (master).
3. Run tools\scripts\CreateUnityPackage.bat in an administrator cmd window.

   Note: It may take a while to build external dependencies for Spectator View's native components the first time this script is run.

4. Copy the generated packages\com.microsoft.mixedreality.spectatorview.* somewhere in/near your project (don't place the package inside your Unity project's Assets folder).
5. Add a reference to the com.microsoft.mixedreality.spectatorview.* folder to your Unity project's Package/manifest.json file. For more information on referencing a local Unity package, see here.

Referencing MixedReality-SpectatorView as a submodule

1. Add the MixedReality-SpectatorView repository as a submodule to your preexisting git repository.
2. Checkout your desired branch (master).

   Note: It may take a while to build external dependencies for Spectator View's native components the first time this script is run.

3. Run tools\scripts\CreateUnityPackage.bat in an administrator cmd window.
4. Add a reference to the submodule folder src/SpectatorView.Unity/Assets in your Unity project's Package/manifest.json file. For more information on referencing a local Unity package, see here.

Note 1: Creating a unity package is only supported on PCs. You can prepare the repo on Mac for building the iOS example applications by installing powershell and running tools\scripts\SetupRepository.ps1.

Note 2: If your development setup does not allow for symbolic links, running tools\scripts\CreateUnityPackage.bat -HardCopySymbolicLinks will replace symbolic links in the project with copied file content. This should allow developers to generate unity packages, but it will make it more difficult to edit and contribute submodule changes.
