    This document helps you get started with Game Multimedia Engine (GME).

    1. Basic GME Knowledge

    2. GME Billing Modes

    GME currently provides multiple services, such as voice chat, voice messaging, and speech-to-text features. For billing details, see Pay-as-You-Go Billing Mode.

    3. Free Demo

    You can scan the QR code in Free Demo to download the mobile application or download the executable program for the Windows platform to experience the 3D sound effect.

    4. Getting Started

    4.1 Activate the service

    Before using GME, you need to sign up for a Tencent Cloud account and activate the GME service. For more information, please see Voice Service Activation Guide.

    4.2 Obtaining the access parameter

    After activating the GME service, you can find the AppID and permission key in the details page of the created application.

    • The AppID and permission key are required in the Demo as parameters.
    • During the usage of SDK, the initialization API “Init” needs to use AppID as a parameter. The authentication APIs “QAVAuthBuffer.GenAuthBuffer” (voice chat) and “ApplyPTTAuthbuffer” (speech-to-text) all require permission key as parameters.

    4.3 Downloading SDK

    You can download the GME SDKs for different platforms. For details, see SDK Download Guide. Currently, GME supports Windows, Mac, Android, and iOS, and GSE supports UnrealEngine4, Unity3D, and Cocos2DX.

    GME supports the real-time audio call on H5 .

    4.4 Accessing SDK

    To access the SDK of each platform, you can refer to the project configuration document of each platform to configure the project, and then check the API Documentation of the corresponding platform to call the APIs to use GME services. The calling sequence of voice chat APIs is Init API (for initialization) > Poll API (for callback trigger) > EnterRoom API (for entering a voice chat room) > EnableMic API (for enabling the mic) > EnableSpeaker API (for enabling the speaker) > ExitRoom API (for exiting the room) > Unit API (for uninitialize).

    The room entry process of voice chat is shown as follows:
