v2.2.1

v2.2.1 was released on Jul 23, 2019.

This release adds support for the arm64-v8a architecture on Android.

v2.2.0

v2.2.0 was released on January 28, 2019. See below for new features and API changes.

New Features

1. Set the Voice-only Mode

Adds the SetVoiceOnlyMode method to set the voice-only mode. Once voice-only mode is enabled, the SDK transmits only the voice stream, but not other streams, like the sound of keyboard strokes. This function effectively optimizes the audio quality.

2. Set the Audio Effect Playback Position

Adds the SetRemoteVoicePosition method to set the playback position and volume of the audio effects sent from the remote user.

3. Enables/Disables the Local Audio Module

When an app joins a channel, the audio module is enabled by default. Added the EnableLocalAudio method to disable and re-enable the local audio capture, that is, to stop or restart local audio capturing and processing. The OnMicrophoneEnabledHandler callback is triggered once the local audio module is disabled or re-enabled. This method does not affect receiving or playing the remote audio streams, and is applicable to scenarios where the user wants to receive remote audio streams without sending any audio stream to other users in the channel.

4. Sets Whether to Receive the Audio/Video Streams by Default

Added the SetDefaultMuteAllRemoteAudioStreams and SetDefaultMuteAllRemoteVideoStreams methods to set whether to receive the audio or video streams by default.

5. Indicate the First Local Audio Frame is Received/Sent

Added the OnFirstRemoteAudioFrameHandler and OnFirstLocalAudioFrameHandler callbacks to indicate that the first remote audio frame is received or sent successfully.

6. Indicate an API is Executed

Added the OnApiExecutedHandler callback to indicate that an API method is executed.

API Changes

Added

• EnableLocalAudio
• SetDefaultMuteAllRemoteAudioStreams
• SetDefaultMuteAllRemoteVideoStreams
• OnMicrophoneEnabledHandler
• OnFirstRemoteAudioFrameHandler
