Introduction

Audio mixing means that the SDK integrates third-party audio data with the audio data collected by the microphone into an audio stream, so as to play sound effects (such as applause, whistle), custom sounds, music files, etc. During a call or live broadcast, and let Other members in the room can also hear the sound.

Prerequisites

Before using audio mixing, please make sure:

• A project has been created in ZEGOCLOUD Console and applied for a valid AppID and AppSign. For details, please refer to Console - How to view project information .
• ZEGO Express SDK has been integrated into the project to implement basic real-time audio and video functions. For details, please refer to Integrate the SDK and Implement a basic video call.

Start Mixing

After pushing the stream, call the startMixingAudio method to start mixing, and use the "streamID" and "mediaList" (media tag list: "video" or "audio") to mix the audio into the stream being pushed.

const result = zg.startMixingAudio(publishStreamId, [
    $('#extenerVideo1')[0],
    $('#extenerVideo2')[0],
]);
console.warn('mixed', result);

Stop Mixing

Call the stopMixingAudio method to stop mixing.

zg.stopMixingAudio(publishStreamId);
