TUIRoom (Windows and macOS)
TUIRoom is based on Tencent Real-Time Communication (TRTC) and Tencent Cloud Chat. With TUIRoom:
The host can create a room, and participants can enter the room ID to join the room.
The participants can share their screens with each other.
All room members can send text chat messages and custom messages.
Note
TUIRoom is an open-source class depending on two closed-source Tencent Cloud SDKs. For the specific implementation process, see Integrating TUIRoom (Windows and macOS).
The TRTC SDK is used as a low-latency video conference component.
The Chat SDK (C++ edition) is used to implement chat messages.
