Features

• 1:1 audio/video calling
• camera and media-file video source switching
• real-time call stats in the sidebar
• repeated-call handling fixes for stale signaling, ICE timing, and one-way video regressions

Requirements

• Windows
• Visual Studio C++ build tools
• clang-cl
• cmake
• ninja

Build

Use the batch script from a normal Windows shell or Developer Command Prompt.

build.cmd clean
build.cmd
build.cmd debug
build.cmd test
build.cmd test debug

Notes:

• default build is release
• build output lives under build\release or build\debug
• build.cmd clean removes the whole build\ directory
• build\compile_commands.json is synchronized from the active config directory after configure/build
• build.cmd test builds then runs ctest --verbose automatically for the selected config, showing each test case

CMake preset

This repository also provides a default Ninja preset:

cmake --preset default
cmake --build --preset default

To run tests manually after build:

ctest --test-dir build\release --output-on-failure
ctest --test-dir build\release -N
ctest --test-dir build\release -V

Signaling server

The client expects the matching signaling service in:

webrtc-signaling-server/

Update the server URL in the app configuration if your deployment target changes.
