This document describes the upgrade of GME.
Upgrade from GME 2.x to 2.9
SDK updates
Dynamic library split
Rename Android package
The GME SDK is updated with the following new library files in addition to libgmesdk.
Library files' corresponding features
The new version of GME splits the dynamic libraries to reduce the package size. You can only import the library files you need. For example, if you only need the voice changing feature, to import libgme_soundtouch is good.

Upgrade Notice
Upgrade from GME 2.2 to 2.3.5
SDK updates
New features
Offline voice can be used during voice chat now.
Voice chat can filter offensive, insecure, or inappropriate information.
HTML5-based voice chat is supported now, making voice chat available across all operating systems.
Android v8a architecture is supported now.
Low-latency capture and playback is adaptive to Android now.
Optimizations
Optimized the range voice APIs of the SDK to lower the access threshold.
Optimized noise reduction for voice.
Greatly reduced memory usage by the SDK.
Changes in Major APIs
EnterRoom
The room entering operation has been changed from sync to async. If the return 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 exiting operation has been changed from sync to async. It is handled in the same way as the RoomExitComplete callback function. If the return value is AV_OK, the async delivery is successful.
Note:
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
For uniform processing of all error codes, use !AV_OK.
To handle the errors separately, focus on the type of error returned by the API.
Note:
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 before v2.3, please see the table below for version comparison.
|
For mutual exclusivity with other modules | Change PauseAudio to Pause and change ResumeAudio to Resume |
For using offline voice in voice chat | Delete PauseAudio and ResumeAudio |
Changes in the Parameters of the SetLogLevel API
Original 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
|
