How can I listen for the status of a user's microphone and camera?

Introduction

When using the Agora RTC SDK to implement a real-time call or interactive streaming, to listen for the status of a user's microphone and camera in a channel, you can use the Agora RTM SDK.

Implementation

You can use the following functions of the Agora RTM SDK to listen for the status of a user's microphone and camera in a channel:

• User attributes: Listen for the status of a specified user's microphone and camera by adding user attributes.
• Channel attributes: Listen for the status of all users' microphones and cameras in a specified channel by adding channel attributes.

Listen for user attributes

1. After joining a channel, call addOrUpdateLocalUserAttributes to add or update the attributes of the local user's microphone and camera.
2. Call getUserAttributesByKeys to get the attributes of a specified user's microphone and camera, which can be used to show the microphone and camera status.

Listen for channel attributes

1. (This step is for Linux/Windows C++ only, skip to step 2 when using other platforms.) After joining a channel, call createChannelAttribute to create and return an IRtmChannelAttribute instance.

2. Call addOrUpdateChannelAttributes to add or update the attributes of all users' microphones and cameras in a specified channel.

3. Call getChannelAttributesByKeys to get the attributes of all users' microphones and cameras in a specified channel, which can be used to show the microphone and camera status.
