Breaking changes

  • Upgrade the VC++ runtime DLL files. Use the VC++ 2022 redistributable runtime DLL files.

  • Add support for I420Limited and I420Full in the MSDK external video source.

    • In rawdata_video_source_helper_interface.h, remove the last parameter FrameDataFormat format of sendVideoFrame.

      class IZoomSDKVideoSender
{
public:
 virtual ~IZoomSDKVideoSender(){}
 virtual SDKError sendVideoFrame(char* frameBuffer, int width, int height, int frameLength, int rotation) = 0;
};

    • Add a new parameter FrameDataFormat format to setExternalVideoSource.

      class IZoomSDKVideoSourceHelper
{
public:
// ..........................................................
 /**
  * @brief Sets external video source for capture video by self.
  */
 virtual SDKError setExternalVideoSource(IZoomSDKVideoSource* source, FrameDataFormat format) = 0;
// ..........................................................
};

      struct BOOption
{
bool isAICompanionEnabled;
bool isTranscriptionEnabled;
};

    • Add new interfaces in class IBOCreator.

      virtual bool IsAICompanionSupported() = 0;
virtual bool IsTranscriptionSupported() = 0;

    • Add a new interface in class IMeetingApproveStartSmartSummaryHandler.

      struct FaceROI
{
 float left;     ///< Normalized left edge,   [0.0, 1.0].
 float top;      ///< Normalized top edge,    [0.0, 1.0].
 float right;    ///< Normalized right edge,  [0.0, 1.0], > left.
 float bottom;   ///< Normalized bottom edge, [0.0, 1.0], > top.
};

class IFaceROIInfo
{
public:
 virtual unsigned int GetFaceCount() = 0;
 virtual const FaceROI* GetFaceROIByIndex(unsigned int index) = 0;
 virtual ~IFaceROIInfo() {}
};

    • Add a new function GetFaceROIInfo to YUVRawDataI420.
