This document describes the upgrade of GME.

Upgrade from GME 2.2 to 2.3.5

SDK updates

New features

• Voice messaging and speech-to-text conversion can now be used during voice chat now.
• Voice chat can now be filtered for terrorism, pornographic, and politically sensitive information.
• HTML5-based voice chat is now supported, making voice chat available across all operating systems.
• Android v8a architecture is now supported.
• Low-latency capturing and playback are now adapted to Android.

Optimizations

• The range voice APIs of the SDK are optimized to lower the access threshold.
• Noise reduction for voice is optimized.
• Memory usage by the SDK is greatly reduced.

Changes in major APIs

EnterRoom

The room entry operation has been changed from sync to async. If the returned value is 0, the async delivery is successful and waiting to be processed by the callback function; otherwise, the async delivery fails.

public abstract int EnterRoom();

ExitRoom

The room exit operation has been changed from sync to async. It is handled in the same way as the RoomExitComplete callback function. If the returned value is AV_OK, the async delivery is successful.

If there is a scenario in the application where room entry is performed immediately after room exit, you don't need to wait for the RoomExitComplete callback notification from the ExitRoom API during API call; instead, you can directly call the API.

public abstract int ExitRoom();

Changes in error codes

• If you need to handle all error codes uniformly, use !AV_OK.
• If you need to handle each type of errors separately, pay attention to the error type returned by the API.

Error code "1" has no specific meaning and will no longer be returned since v2.3.5, so it has been deleted.

Changes in other APIs

PauseAudio/ResumeAudio

public int PauseAudio()
public int ResumeAudio()

If the ITMGAudioCtrl::PauseAudio or ResumeAudio API is called in an SDK below version 2.3, please see the table below for version comparison.

Changes in SetLogLevel API parameters

Legacy API

ITMGContext virtual void SetLogLevel(int logLevel, bool enableWrite, bool enablePrint)

New API

ITMGContext virtual void SetLogLevel(ITMG_LOG_LEVEL levelWrite, ITMG_LOG_LEVEL levelPrint)

Parameter description

ITMG_LOG_LEVEL type

Upgrade from GME 2.3.5 to 2.5.1

ITMGContextGetInstance()->GetAudioCtrl()->GetSendStreamLevel();

This API is used to get the real-time audio downstreaming volume levels of other members in the room. An int-type value will be returned. Value range: 0–100.

iter->second.level = ITMGContextGetInstance()->GetAudioCtrl()->GetRecvStreamLevel(iter->second.openid.c_str());
