Another utility to extract the GPS data from the 70mai MP4 files, on Linux:
https://pastebin.com/raw/rd94wQH7
Just compile the program and run.

I have updated WinMp4Extract.
Now, after program extracts GPS data, moves MP4 video, SRT and KML files to the Done folder inside project folder.
If extracted files exist in folder Done, program will offer you to replace them with new or leave them.

I have updated WinMp4Extract to version V1.2.2.
I have fixed one bug - false detections of missing generated KML and SRT files.
Install version was missing mp4extract.exe - that was fixed in this release.

I do everything according to the instructions, but when I enter the command to the video so it tells me that the file does not exist.  Any advice? My english bad - google translator :)

Can you post screenshot of the message you get? I don't remember that program has message File doesn't exist.

I send link to photos. https://www.dropbox.com/sh/3x49wwztz4hoeov/AACSSxVGcZQzFMEn0cCBpOsga?dl=0
Maybe not work therefore that my system is 32 bit?

What file do you starting? You need to doubleclick on WinMp4Extract (file with icon of the 70mai camera).
Then you will get main window as on the images in my post.
Try and let me know how it went.

Ok. Thanks for advice.
Everything works as it should but then the program writes that there is no gps data in the video and I have a camera with gps. Where can there be a problem?

I download and install English firmware v.1.0.8na (SSH, auto create SRT / KML / GPX with GPS + USB STORAGE)
but the program also writes that there is no gps data in the video.

Did you try to select the same video file again?
When program show you no gps data message, try to select it again and repeat extracting.

I've tried it multiple times, but always without success.

Do you see GPS data from that video inside 70mai app? I will check when it happents and try to repeat result you have.

OK, I have found what is your problem.
As I can see from attached images, you have copied files to your desktop.
Windows are blocking something because files are on the desktop, and program can't extract data.
I have copied my files on desktop and got the same result as you are.

Can you, please, move gps folder to the root of the C partition (or better to the D if you have another partition) so path will be C:\gps or D:\gps?
Then, when you click Choose MP4 video, make sure to select video from C:\gps folder.

Now it will work.

Beside that, you can try install version of the program. That version will install all needed files to the Program files folder and you will have all needed rights.

Hey Amicus, see my link to pastebin above - if you integrate this into your tool, you won't need the mp4extract and gps executables.

I installed the install version of winmp4 to pc but the same problems repeat as before. So I gave up :). Now I installed English firmware v.1.0.8na (SSH, auto create SRT / KML / GPX with GPS + USB STORAGE) and then I used soft Dash cam aka Registrator viewer and there it works ok.
Thank you for your willingness to address this issue.

Hello. I will take look at that.
I will try to integrate it to the .net project.
I will let you know how it went.

Sure: https://pastebin.com/vGZWUb98

M-DRV_1576477583462 Sure: https://pastebin.com/vGZWUb98

@M-DRV_1576477583462 Thank you for your code.
I have just tried it and it works.
I need to optimize my program to work with your functions for GPS data extraction, to dumpit to SRT file and to make some error handling and I will post new version.
It seems quite fast.
Thanx again

@ Amicus  Is that possible to import the GPS records, which was extracted by GUI,  to google maps to check the GPS tracking route?

Basically it is. I just need to create export to KML file which is kind of XML.
I will create test export just to confirm if it is possible.
Later I can include that as another expirt option.
I will let you know how it went.

I can confirm that I can export GPS data to the KML file that can be imported in Google Earth or any other program that can work with KML files.

NOTICE!
I have just updated program to version V2.0.1.
This version doesn't use command line tools for extracting GPS data.
Thanx to the forum user M-DRV_15764775 program has it's own engine for extracting GPS data from 70mai Pro MP4 videos.
I suggest you to download and nstall new version (links are in first post) because it's much simplier to use and faster.

Program extracts GPS data from MP4 video and creates SRT and KML files.

Please fell free to post suggestions or errors you find in the program.

Hi Amicus,
the program finally works 100% for me. Thank you for your patience and I believe that this program will help other users as well. Of course, I also thank the user M-DRV_15764775. Program is very simpl. The program is very easy to use.

Well, congratulations!

Hi Amicus, good job for the project of retrieving GPS data from video file. But ...there is a problem.
I tried to extract GPS data. It give me two files, .SRT and .KML. The SRT file it's okay if you want to use as a subtitle for video, but KML have a big problem. The problem is that the timeline is missing. For each coordinate the time is missing. In the SRT file the timeline is correct but not in the KML file. I tried to use map overlay using KML but it's not working.

Hello. Thank you for the kind words. 
I have tested KML file with Google Earth and I get all the points on the map without any problems.
But regarding time - It's correct. I don't export time into the KML file.

I will look for official KML specification and apply it.
Thank you for your observation.

I have just updated WinMp4Extract to version 2.1.3.
I have added new options, as showing/hiding max. speed in SRT file, showing/hiding GPS coordinates in SRT file, showing/hiding speed statistics on main window, adding timestamp in to the KML file.

@M-DRV_1587770514597  I have found the way to add TimeStamp to the KML file. I couldn't find the way to read date/time from the video and I have taken date and time from the name of the video.
If somebody has changed the name, prgram will read date and time from video properties.
Please try now overlay and let me know the result.
I have tested it with Google Erth and it looks good. If I doubleclick first point, all other disapear. Then I double click the name of the KML file and all other points are shown one after anothr in direction of driving.

Other people download without problems.

Hi Amicus, good news about updating the software. I don't have time to try it now, but i'm sure that is perfect. Thank you.

thank you again, well when i put the kml file at google earth it goes to africa and I live in Brazil, i think i understand the issue, my location is S7.94766 W34.89323 google earth just see this as 7.94766 (positive)/(north) and 34.89323 (positive) (east) when then right coordenate for south and west is negative -7.94766 and -34.89323. I hope you can understand me and fix it, thank you very much.

O hello Brazil :)
It's good that you we have chance to test videos from southern hemisphere.
If c1 = "N" Or c1 = "S" Then
Your script for reading GPS data treats data from norhern and southern hemisphere in the same way. That means that GPS coordinates in the camera videos are always positive.
But, of course, ther is letter N or S which defines hemisphere.
I'm fixing that. I will add minus (-) sign for sothrent hemisphere longitudes.
The same goes for western latitudes (W).
Thank you again for your observations.

You are welcome.
If you have idea what else option could be added, please share it here.
If it's possible, i will implement it.

I'm thinking about adding batch extract option that will extract GPS data for all videos in selected folder.
What do you think about it?

nice Idea

I have just updated WinMp4Extract to version 2.2.3. (check first post)
I have added new option - program now can do batch extraction.

You can now select folder and program will extract GPS data from all videos in one step.

Videos that doesn't have GPS data will be skipped.

Amicus I'm thinking about adding batch extract option that will extract GPS data for all videos in selected ...

Another idea is to embed the subtitles directly in the MP4. This would allow playback using simpler video players, and also easier upload to YouTube etc.
If you have ffmpeg installed (or packaged with the tool), the command to embed subtitles is:
ffmpeg.exe -i NO20200505-105610-002272.MP4 -i NO20200505-105610-002272.MP4.srt -c copy -c:s mov_text outfile.mp4

M-DRV_1576477583462 Another idea is to embed the subtitles directly in the MP4. This would allow playback using simpler ...

It's good idea.
I will try to implement it.

I was thinking about making video player that will read GPS data directly from dashcam video.
But I don't have a time for such project now.
Maybe in the future.

Could you put the source code to a git repository? Would be fun to look at the code. :) 
Another thing is, could you connect with GoogleMaps API somehow and put the GPS data straight to GoogleMaps?
Also it would be good if we could set the interval to extract data.

Thanks for your work!
Regards!

I looked in to Google API because I wanted to read altitude, but I could't find free way of using it. I'm not prepared to pay for using Google API.

Interval for data extraction is set by the  data in the video. As I know, camera is storing GPS data once per second. According to that, I can set longer but not shorter interval than 1 second but I don't see why would I skip any GPS point on video that can be long from 1 to 3 minutes.
If people want to lower GPS point resolution, I can implement that.
Please write your oppinion here.

I have just updated WinMp4Extract to version 2.3.3. (check first post)
I have added new option - now it's possible to choose GPS data extraction interval.

You can read GPS data every 1, 2, 3,  5 or 10 seconds.

hey, can you please update it by dropbox for me?

M-DRV_1582807953594 hey, can you please update it by dropbox for me?

Sorry, I don't use dropbox.

Check first post - there is new version of the program.
After you import KML file, you can now see speed data for every placemark. First and last are clickable.
Currently I'm showing name of the MP4 video and speed.
Do you have suggestion what else to show?

please update in another server, i can't open your page, always even in 4G, i think it's blocked in Brazil

Hello Amicus! Firstable, congrats for the application. It's totally geniusly and I appreciate very much your efffort to provide us a solution and workaround that supposely be done by the manufacturer (what is a shame). Anyways congrats! My feedback is related the portal where you provide the application. Definetely is not reachable from Brazil network segment. Probably the server where is hosted, do not allow requests from Brazilian network range. Just to you have an idea, I downloaded a VPN software, connects to US via VPN and from there I was able to reach your site, then download. To make the things easy to everyone here, as well contribute with something, I share the latest version on G-Drive by the link below. https://drive.google.com/file/d/11iJd8Fsx_P1DkOZ3MX0dGyARVpn2ABWa/view?usp=sharing

Thank you DS3. I'm glad to hear that you find my program useful.
I have contacted my hosting provider about blocked access from Brasil.

I would also like to have the Linux code, then it would be easier to build scripts for batch processing.

Hello, amicus,
I've just installed portable 2.6.0. It works ok, I can see speed and GPS data when playing MP4 files, but when I import KML data to Google Earth it sends me to the middle of ocean.
My coordinates GPS are for instance:
N40.71291 W4.18611
But in KML files I see that coordinates are 
<coordinates> 4.18611, 40.71291, 0 </coordinates> 
I've edited KML file inserting a minus sign before 4.18611 and it works ok. 
I think it is a minor error that winmp4extract does not reflect west coordinates.
The same occurs with GPX files.
Everything else works all right.
Are you going to implement this change?
Thanks a lot for your fine program.
Best regards.
Miguel

Hi M-DRV_1594374849057 
Thank you for the info.
It's possible that there is a bug.
I have made procedure for detecting north, south, west and east hemispheres but I couldn't test it because I don't have video from all four hemispheres.
I will check my code according to your instructions but I will need few days becase I'm bussy now.
I will send you a message when I fix it.

Thanks, Amicus.
There is another bug, not very serious, When there is no GPS data embeded in MP4 file, program crashes. It doesn't matter because is irrelevant as GPS data was not recorded due to have not obtained a GPS lock.
Anyway, if you consider to correct this bug I send a sample MP4 file producing this error and errror doc

I cannot submit MP4 file is too large.

After you click on the moving arrow you need to follow instructions from one of the posts above.

By now, 1244 people have downloaded WinMp4Extract (install + portable) from my web site, so please be patient and try again.

I have just made new version of the WinMp4Extract (version 2.6.2).
Progam can now detect GPS signal interruption in the video and show message 'No GPS data!' in the SRT file. (check the first post). 

I'm still waiting for 70mai Pro dash cam video from western hemisphere to check the buga that user M-DRV_1594374849057 has reported.
If someone have video recorded on western hemisphere, please contact me thru private messages.

can somebody please upload the newest version on dropbox or something similar for brazilians users please

I have just made new version of the WinMp4Extract (version 2.6.4).
Thanx to reported bugs, I have made fixes. Program can now detect W and S coordinates and create proper KML and GPX files.
I have fixed detection of the videos with no GPS data. (check the first post).

Special thanx to Robson for sending me dash cam videos for testing.

Hi, Amicus.
I've downloaded the last version 2.6.4, an I'm sorry to tell you that you have a minor error.
My GPS coordinates are N40.71265, W4.18505, which are ok in SRT file. So in KML an GPX files they should be  -4.18505, 40.71265.
Erroneously GPS coordinates are 4.18505, -40.71265 corresponding to S40.71265 E4.18505.
You have changed the minus sign in the wrong place.
WinMp4 extract works now very well but for this little error. 
My location is near Segovia(Spain). I'll try to send a MP4 file for testing if you need it.
Thanks very much for your program. 
Best regards.

Now it works perfectly in every aspect, but I've noticed that traveled distance is always 0,0Km. I don't know why, I use Registrator Viewer 6.0.0.22 to play the videos and this program reflects the distance ok as 2401m.

Perhaps it is another error.

I adjoin a capture of Registrator Viewer.
Best regards

Hi.
You are welcome.
I have tested SRT file generation with videos from Slovenia, Brasil and Spain and I always get distance.
You can see screenshot from my video player (video from Slovenia)

Can you send me your video so I can check what is happening?

Is it possible that your video player doesn't understand formatting tags (<i> </i>) for distance?

Can you try playing video in some other video player (like Media Player classic, or VLC player)?

When i try to extract GPS data i receive this message from the programme! Please, explain where the problem is? Thx

Hi.
I can't say what is wrong without yours video.
Did you try to repeat extraction, or to click Continue?

If you send me video you tried to extract I will run program in debugging mode and find exact point when error occured.

You can upoload video to google drive and share it with me.
Send link to my email or over private messages.

Hi again, Amicus, forgive the bother
I've played it with MP-HC and VLC and distance traveled is always 0,0 Km.
All players interpret tags ok but looking the contents of SRT file I see that in all points dist es 0

Hello.
Thank you for sending your video.
I have tried extracting GPS data and everything is working as it supposed to.
I have distance shown thru entire video, as you can see on the image below.

Is it possible that you are missing some components in your system?
Are you using portable version of the WinMp4Extract?
Please try istall version as it should add missing components from NET framework 4.6.1.
If that doesn't help, please try to reinstall NET framework 4.6.1.

I've tried the installed version with the same results. 

I hvae a more advanced Net Framework

Get-STDotNetVersion gives the following:

ComputerName : localhost

>=4.x        : 4.8 or later

v4\Client    : Installed

v4\Full      : Installed

v3.5         : Installed

v3.0         : Installed

v2.0.50727   : Installed

v1.1.4322    : Not installed (no key)

Ping         : True

I suppose version 4.8 or later supercedes 4.6.1
I will investigate.
Forget it.
Thanks again.

M-DRV_1594374849057 I&#39;ve&nbsp;tried&nbsp;the&nbsp;installed&nbsp;version&nbsp;with&nbsp; ...

You can try one more thing - check decimal symbol on your PC. I might have hardcoded decimal point as a decimal symbol.
If you have configured comma as decimal symbol it could produce 0 for traveled distance.

Can you please check that and let mi know?

M-DRV_1594374849057 I&#39;ve&nbsp;tried&nbsp;the&nbsp;installed&nbsp;version&nbsp;with&nbsp; ...

Now I see on the screenshot that you have comma as a decimal symbol.
So I have fixed that.
Program should now use system default settings for decimal numbers.
Traveled distance calculation should be working now without problems
I will send you test version so you can check it on your PC before I publish new release.

When I press continue, the program creates the srt file, but it`s empty - 0 bytes!

Thanks in advance!

Hi.

It seems that you have problem with writing rights to your WinMp4Extract root folder.

Try to make folder writable for current user or move program to other partition.

I have tested your video and it all worked well.

In attachment you can find SRT and KML files generated from your video.

Thanks, Samir
That is the problem. I have comma as decimal point. 
I see in your screenshot of my video  that you have decimal point, and comma in mine, as you said.
I'll try your latest version when it is available.
Regards.
Miguel

I have sent link to test version to your private massages on this forum.
Can you chech if you have receive it?

Hi, Samir
I didn't notice that you had sent me the file.
I've tried it and it seems that now calculates ok the distance traveled. It appears correctly in SRT file, but you must have corrected a previous version of your program because KML and GPX files have the wrong GPS coordinates, they have lost the minus sign corresponding to West coordinates.

I adjoin the SRT, KML and GPX files generated

Thanks for your interest.

I have just made new version of the WinMp4Extract (version 2.6.7).
Thank you everyone for reporting bugs.
I beleive that I have fixed all reported bugs.

Some users have problems with getting empty or no SRT, KML and GPX files, but problem is not in the program - problem is in the Windows access rights for the folders.

Hi, Samir
As far as I am concerned it works now perfectly.
Thanks very much.
Regards.
Miguel

Worked for me. For some reason I selected 1 file from the folder yet it did for all, but still , it works. Thanks

If you have selected MP4\Select Folder then it it WILL extract GPS data from all videos from selected folder.
If you select MP4\Select Video then it will extract only selected video.

I can't see how it could extract all videos from some folder if you have selected only one video because I have programmed it to load only selected video and to stop.

Only in case of selecting folder (MP4\Select Folder) program will read all names of the MP4 files in that folder and try to extract GPS data from all of them.

Please, try extraction again.

You are welcome. 
I hope I will get some credit for making it possible.
