Losing GPS data when I extract frames from mp4 video

Hi guys,

I have a mp4 video from a GOPRO with GPS data, but when I extract frames of this video with matlab I loose all the GPS data.

Does anyone already had this problem and could help me, please?

 clc;
 clear all;
 close all;

vid=VideoReader('C:\Users\Cinthya Ruffo\Desktop\teste códigos prospecção por imagem\videovieira2.mp4');
numFrames = vid.framerate;
duration = vid.Duration;

 mkdir('teste');

 Folder = ('C:\Users\Cinthya Ruffo\Desktop\teste códigos prospecção por imagem\teste');

for iFrame = 1:duration
  frames = read(vid, iFrame);
  imwrite(frames, fullfile(Folder, sprintf('%06d.jpeg', iFrame)));
end 
FileList = dir(fullfile(Folder, '*.jpeg'));
for iFile = 1:length(FileList)
  aFile = fullfile(Folder, FileList(iFile).name);                                                                               
  img   = imread(aFile);
end

cd('C:\Users\Cinthya Ruffo\Desktop\teste códigos prospecção por imagem\teste' );
list = dir('*.jpeg');
[m n]= size(list);
sz = [m 3];
varTypes = { 'string','string','string'};
varNames = {'ImageName','Lat','Lng'};
T = table('Size',sz,'VariableTypes',varTypes,'VariableNames',varNames);
for i = 1:m
       disp(list(i).name);
       imgName = list(i).name;
       info = imfinfo(imgName);
       if isfield(info.GPSInfo)
       lat = info.GPSInfo.GPSLatitude;
       lng = info.GPSInfo.GPSLongitude;
       strLat = lat(1) + "," + lat(2)+ "," + lat(3);
       strLng = lng(1) + "," + lng(2)+ "," + lng(3);
       T(i,:) = {imgName, strLat,strLng};
       else 
       lat = [0 0 0];
       lng = [0 0 0];
       strLat = lat(1) + "," + lat(1)+ "," + lat(3);
       strLng = lng(1) + "," + lng(1)+ "," + lng(3);
       T(i,:) = {imgName, strLat,strLng};
end
