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
• Use python 3.9.x (not 3.10 or higher as these removed packages needed)

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".
