readme

Binary only

Check out the release page to download either the debug or release xcframework. Then unzip and include xcframework into your own project. They should work similarly to the builds from https://github.com/stasel/WebRTC

Build from source code

Setup

Clone recursively:

git clone --recursive https://github.com/because-why-not/webrtc_visionpro_workspace

The customised webrtc source code will be cloned to the subfolder src. The build toolchain had to be customised as well. You find it at src/build

Building for vision pro

After cloning run ./setup_xros.sh to create the gn project. This will also run gclient sync for you to download the third party dependencies. It will take a long time!

After this completed run ./build_xros.sh to build the WebRTC.framekwork for both the simulator and the device.

You find the output at:

./src/out/simxros-arm64-debug/WebRTC.framework
./src/out/xros-arm64-debug/WebRTC.framework

Check out the contents of the .sh files for details. If you use a custom XCode installtion you can set this via the env.sh or the environment variable XCODE_PATH.

The build will use the iOS toolchain of WebRTC but changes the SDK to xros, uses the clang version of xcode and customises some compiler flags. My own test project does run in the vision pro emulator but I do not have an actual device for testing.

If you have a vision pro please try the WebRTC.framework in your own project and let us know the results!

Create a complete build

Run ./build_all.sh. This will run all the platform specific setup and build scripts and then combine the results into xcframeworks. The result should be a webrtc_debug.xcframework and webrtc_release.xcframework. Also a symlink webrtc.xcframework is created which will link to the release build by default and is used by the example app in the folder MinTestApp

Running the test app

All the test app does is creating a RTCPeerConnectionFactory to ensure WebRTC can be started. To run it open the MinTestApp/MinTestApp.xcodeproj with xcode, select your platform and press run. It will print "Hello world" and log some information in the console (debug builds).
