像进行JPEG解压缩，并将解压缩后的图像存储到视频文件中。

outputVideo =好的，根据您的要求，我可以为您提供以下C++代码来实现所需功能，其中使用了哈希表来维护key-value关系：

#include <unordered_map>
#include <ctime>

struct KqiInfo {
    uint64 VideoWriter('compressed.avi');
open(outputVideo);

for k = 1:numFrames
    decoded_img = decoded_imgs{k};
    % 调_t imsi;
    uint64_t imei;
    uint32_t eci;
    uint16_t tac;
    timespec last_time;
};

std::unordered_map<uint64_t, KqiInfo> kqi_map;

void update_kqi_map(S1MMEKQI用jpegdec函数进行JPEG解压缩
    img = jpegdec(decoded_img);
    writeVideo(outputVideo,img);
end

close(output* kqi, S1APNode* p_node) {
    MsgCommonInfo& common = p_node->GetCommonInfo();
    SPUserInfo& sp_user_info = p_node->GetUserInfo();
    uint64_t imsi = sp_user_info->GetIMSI();
    uintVideo);

完整的代码如下：

% 读取视频文件并将每一帧图像进行64_t imei = sp_user_info->GetIMEI();
    uint32_t eci = common.eci;
    uint16_t tacJPEG压缩
vidObj = VideoReader('sample.avi');
numFrames = vidObj.NumberOfFrames;

for k = 1:numFrames = common.tac;
    timespec now;
    clock_gettime(CLOCK_REALTIME, &now);
    KqiInfo kqi_info = {imsi, imei, eci, tac, now};
    kqi_map[imsi] = kqi_info;
} 

在
    img = read(vidObj, k);
    compressed_img = jpegenc(img); % 调用jpegenc函数进行JPEG压缩原有的S1mmeSession::CtEncodeKqi函数中，调用update_kqi_map函数即可将相关信息保存到哈希表中。如果imsi已经存在，会自动覆盖原有记录；如果imsi不存在，则新，返回压缩后的图像
    % 将压缩后的图像存储到数组中，用于后续的建一条记录。需要注意的是，本代码中使用的哈希表默认使用std::hash函数进行哈希，如果需要自定义哈希函数可以通过std::unordered_map的第三个模板参数传入。
