Structure Definition

struct MxVisionData {
    uint64_t dataPtr;
    int32_t dataSize;
    uint32_t deviceId;
    MxBase::MemoryData::MemoryType memType;
    uint32_t freeFunc;
    std::string dataStr;
    MxDataType dataType;
}

Parameters

Parameter	Input/Output	Description
dataPtr	Input	Video/Image data content. dataPtr must be converted to the uint64 type by the video/image data content pointer and cannot be directly constructed.
dataSize	Input	Data size, in bytes.
deviceId	Input	ID of the device where the data is located.
memType	Input	Memory type of the data. For details, see MemoryData.
freeFunc	Input	Data release function. freeFunc needs to be converted into the uint32 type by the corresponding release function pointer of the data and cannot be directly constructed.
dataStr	Input	Visual data.
