      SDK updates

      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 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.
      Before v2.3
      v2.3
      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)

      Upgrade from GME 2.3.5 to 2.5.1

      New APIs

      GetSendStreamLevel

      This API is used to get the real-time audio upstreaming volume level. An int-type value will be returned. Value range: 0–100.
      ITMGContextGetInstance()->GetAudioCtrl()->GetSendStreamLevel();

      GetRecvStreamLevel

      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());
