Summary: Breaking changes - behavior for SetBOOption, return type of SetBOOption, change OnStartSendShare to asynchronous; add support for new talkback feature; hide the annotation toolbar when screen sharing in the custom UI.

Breaking changes

  • Change the behavior for the function SetBOOption so that when it is called before a breakout room is created, the function returns an error.

    • Change the return type of function SetBOOption from bool to SDKError.
      virtual SDKError SetBOOption(const BOOption& option) = 0;
    • Add new error code.
      enum SDKError
{
    // ....................................................
    /** Returned when attempting to set breakout room options before any breakout room has been created.*/
    SDKERR_BREAKOUT_ROOM_NOT_CREATED
    // .....................................................
};

  • Adapt the Zoom client change to make the callback OnStartSendShare become asynchronous.

  • CreateAnnotateHelper should not be called immediately after starting a share. Only invoke it after receiving the share start callback, indicating that the sharing session is ready.

Added

  • Support talkback audio feature.

    • New interface in IMeetingService class.

      class IMeetingService
{
public:
// ...................
    virtual IMeetingTalkbackController* GetMeetingTalkbackController() = 0;
// ...................
};

    • New interface in IUserInfo class.

      class IUserInfo
{
// ............................................................
    virtual bool IsSupportTalkback() = 0;
// ............................................................
};

    • New class IMeetingTalkbackChannel.

      class IMeetingTalkbackChannel
{
public:
    virtual ~IMeetingTalkbackChannel() {}

    virtual const zchar_t* GetChannelID() = 0;
    virtual IList<unsigned int>* GetUserIDList() = 0;
};

    • New class IMeetingTalkbackCtrlEvent.

      class IMeetingTalkbackCtrlEvent
{
public:
    virtual ~IMeetingTalkbackCtrlEvent() {}
    enum TalkbackError
    {
        /**Operation executed successfully. */
        TALKBACK_ERROR_OK,
        /**Permission denied. */
        TALKBACK_ERROR_NOPERMISSION,
        /**The object being operated on already exists, for example: the invited user is already in the channel. */
        TALKBACK_ERROR_ALREADY_EXIST,
        /**The number of channels exceeded the limit. */
        TALKBACK_ERROR_COUNT_OVERFLOW,
        /**The object being operated on does not exist. */
        TALKBACK_ERROR_NOT_EXIST,
        /**Operation denied. */
        TALKBACK_ERROR_REJECTED,
        /**Operation timed out. */
        TALKBACK_ERROR_TIMEOUT,
        /**Unknown reason. */
        TALKBACK_ERROR_UNKNOWN
    };
    virtual void onCreateChannelResponse(const zchar_t* channelID, TalkbackError error) = 0;
    virtual void OnDestoryChannelResponse(const zchar_t* channelID, TalkbackError error) = 0;
    virtual void onChannelUserJoinResponse(const zchar_t* channelID, unsigned int userID, TalkbackError error) = 0;
    virtual void onChannelUserLeaveResponse(const zchar_t* channelID, unsigned int userID, TalkbackError error) = 0;
    virtual void onJoinTalkbackChannel(unsigned int inviterID) = 0;
    virtual void onLeaveTalkbackChannel(unsigned int inviterID) = 0;
};

    • New class IMeetingTalkbackController.

      class IMeetingTalkbackController
{
public:
    virtual ~IMeetingTalkbackController() {}
    virtual SDKError SetEvent(IMeetingTalkbackCtrlEvent* pEvent) = 0;
    virtual SDKError CreateChannel(unsigned int count) = 0;
    virtual IMeetingTalkbackChannel* GetChannelByID(const zchar_t* channelID) = 0;
    virtual IList<IMeetingTalkbackChannel*>* GetChannelList() = 0;

    virtual SDKError BeginBatchDestroyChannels() = 0;
    virtual SDKError AddChannelToDestroy(const zchar_t* pChanID) = 0;
    virtual SDKError RemoveChannelFromDestroy(const zchar_t* pChanID) = 0;

    virtual SDKError AddUserToRemove(unsigned int userID) = 0;
    virtual SDKError RemoveUserFromRemoveList(unsigned int userID) = 0;
    virtual SDKError ExecuteBatchRemoveUsers() = 0;

    virtual SDKError SendAudioDataToChannel(const zchar_t* channelID, const char* pAudioData, unsigned int dataLength, unsigned int sampleRate, ZoomSDKAudioChannel channel) = 0;
    virtual SDKError SetChannelBackgroundVolume(const zchar_t* channelID, float backgroundVolume) = 0;
    virtual bool IsMeetingSupportTalkBack() = 0;
};

  • Add support for selecting virtual backgrounds in pre-meeting preview.

    • New enum value in RequiredInfoType.
