Follow the instructions below to build the plugin from scratch. If you just want to run and test it check out: https://github.com/because-why-not/uwebrtc_visionpro_testproj

Before building make sure you have:

• Xcode 15.2 with vision os SDK (build a test project first to make sure everything is installed)
• the latest cmake (brew install cmake)
• an ARM based mac build machine
• Unity 2022.3.21f1

Ideally, try to build the official com.unity.webrtc first to make sure nothing is missing.

Build

Setup

In the terminal run the following:

#this checks out the repository and its submoduels
#this includes a fork of com.unity.webrtc which is absolutely massive. We use "--shallow-submodule" to reduce the size
git clone --recurse-submodules --shallow-submodule https://github.com/because-why-not/uwebrtc_visionpro.git
cd uwebrtc_visionpro
#this will download third party dependencies of libwebrtc and can take a long time
./init.sh

If you use a custom Xcode location run export XCODE_PATH=/YOUR/PATH/Xcode.app or edit the env.sh.

Building

#build libwebrtc for the visionos simulator
./build_webrtc_simxros.sh

#build the plugins
./build_plugin_simxros.sh

#for the device build
./build_webrtc_xros.sh
./build_plugin_xros.sh

#for testing in mac os / editor:
./build_webrtc_mac.sh
./build_plugin_mac.sh
    
#sync the build plugin folder and the test project
./sync.sh

Testing

Open the unity project at ./uwrtc_testproj. The project is set up to work with the vision os simulator. For this it will load the plugin from ./uwrtc_testproj/Assets/webrtc/Runtime/Plugins/simxros

To build for the vision pro device rename the folder "simxros" to "simxros~" and then include the device specific plugin by renaming "xros~" to "xros".
