Extracting GPS data from INSV file

[SM26]

Hello everyone

I have a problem, and I hope you can direct me.

I have a 360 camera, Insta360 One X.
It produce an unstitched file in INSV (proprietary) file format.
I can change it to MP4 and it works just fine
or I can use a dedicated programme to produce a stitched version in MP4 format.

The camera records GPS data, and when I use the Android app with the INSV files, I can see all of the GPS data

I was wondering if it was possible to extract all of the GPS data (preferably in GPX format) out of it.

My system:
Windows 10, 64 Bit.
ExifTool V11.26
ExifToolGUI V5.16

In the Gui, I've clicked "Export data to XMP"
but I get "LargeFileSupport not enabled" warning.
I've made a .ExifTool_config file in the same directory as the exiftool itself, with an additional 2 lines (LargeFileSupport => 1 & print "LOADED!\n"; ):

%Image::ExifTool::UserDefined::Options = (
    CoordFormat =&gt; '%.6f',  <span class=com># change default GPS coordinate format</span>
    Duplicates =&gt; 1,        <span class=com># make -a default for the exiftool app</span>
    GeoMaxHDOP =&gt; 4,        <span class=com># ignore GPS fixes with HDOP &gt; 4</span>
    RequestAll =&gt; 3,        <span class=com># request additional tags not normally generated</span>
    LargeFileSupport => 1,

);
print "LOADED!\n";
<span class=com>#------------------------------------------------------------------------------</span>
1;  <span class=com>#end</span>
</pre>
<hr>
<p class='lf'># <a href="index.html">&lt;-- Back to ExifTool home page</a></p>
</body>
</html>

I still get the warning, and I've read FAQ 11 and followed it to the letter, still happening.

Edit:
If it matters, I've also tried to use MetaData++, which is based on ExifTool. still no luck.

I would really appreciate any direction you could throw at me.
I'm also currently upload the INSV file to Google Drive so you can take a look for yourself (it's gonna take some time, it's a 5.8GB file).

TIA

Here is the INSV file if someone is willing to take a look:

So this should work for you if you can get LargeFileSupport enabled.

The config file you posted contains some HTML markup which would stop it from working.  Try this config file named ".ExifTool_config" in the exiftool.exe directory and/or your home directory:

Code: [Select]

%Image::ExifTool::UserDefined::Options = (
    LargeFileSupport => 1,
);
1; #end

Edit:  But wait.  You wanted to extract GPS data.  There is no valid GPS that I can find in this file.  It does contain some GPS information, but it is all void in this video (ie. the receiver didn't acquire a GPS fix).

[SM26]

Thank you Phil,

I've tried this short config file you posted and it works!

and now to the main event, GPS Data.
I can try to create some new testing materials, this time short in duration and small in size for ease of processing.
Do you think that this might help?

I know for a fact that via the app, I can post pictures to Google Street View, so I'm guessing there must be some GPS data hidden somewhere....
I've also dug in their app, nothing useful that I can see.

I'll post here a link to Google Drive when I'll finish uploading all of the new test data.

Thanks Phil!

[Phil Harvey]

I'll take a look at the files that you upload.  Please confirm that the app can obtain GPS from this file alone (often cameras write sidecar metadata files.  Be sure it isn't getting the information from here.  Also, let me know the GPS coordinates it obtains, and whether it gives a single GPS point or a full track from the video.

- Phil

[SM26]

Ok, so I've done 3 short test videos.

But before that, here is how I set it up:

Camera is Insta360 One X, FW V1.17.16.
4K 30 FPS, with "stats" indicator turns on in the app, with "Google Street View" indicator turns on in the app.
Insta360 say that the GPS data is recorded from the phone's GPS, but from what I can tell, it's not inside the app data.

1. Shot first video (vid_050.insv) , saw that I can see GPS data in the app.
2. Backup the INSV file to the PC
3. Format phone, switched to android 9.
4. Load back the INSV file into the phone, GPS data is in the app.
5. Shot while the phone is stationary, and I move around with the camera (Vid_051.insv).
6. Shot while the camera is stationary, and I move around with the phone (Vid_052.insv).

I've also tried to use:

Code: [Select]

ffprobe vid_050.insv output:

OK, I think I can see where the GPS is stored.  Can you tell me ALL of the information displayed by "the app" for the first fix of VID_050?  I need the GPS coordinates, speed, time and whatever else is extracted to be able to decode this from the binary data.

- Phil

Edit:  What is "the app" BTW?  I could run it myself it there is a Mac version available.

[SM26]

from vid_050.insv, the data in the app is:

Time: 00:28 (I can't see frame number in the app)
location: 32° 5′ 16″ N 34° 51′ 22″ E
direction: 288° W
Route +  a dot where I'm on the route + number of Km from the start.
Slope: 47.7%
Elevation: 61.63M
Speed: 2.2 Km/h

I've added a screen shot from the app inside the google drive folder.
(I know that the picture is all black, it's fine, the camera was in my pocket)

[Phil Harvey]

Thanks.  Decoding all this will take some time.  I have found 4 different types of unknown records.  One of these records contains the following information, which gives time/lat/lon plus some other numbers that I don't yet understand.  Here is the dump of the start of this record as decoded from VID_050:

More information:  Here is a dump of the first ten lines of each of the 5 different unknown record types I can find in VID_050.  Please let me know if you know the significance of any of the floating-point numbers in records 0x300, 0x400 or 0x700 (other than the lat/lon in record 0x700, which is obvious).  The first number in records 0x300 and 0x400 is a time code in milliseconds, but I don't know how to relate this to either clock time or a frame in the video.  Records 0x101 and 0x200 are presented as a hex dump, while the others are decoded into variable types that seemed appropriate.

Also, is "IXE3518NYGDB3N" the serial number of your Insta360 One2?

It seems that Record 0x300 may contain accelerometer information from the phone because it contains more interesting numbers for VID_052:

Edit: I think it is likely that after the time code, the next 3 numbers are XYZ acceleration in units of g, and the last 3 numbers are angular velocities about each axis (probably rad/s).

[Phil Harvey]

I've figured out a bit more, and can now decode GPSSpeed, GPSTrack and GPSAltitude, but I need to know what units the GPSSpeed is measured in.  For VID_051, the GPSSpeed starts with a value of 0.83.  I'm thinking this may be in m/s, which would be 2.99 km/h.  What does your app show for the speed at the start of this video?

- Phil

[SM26]

Hello Phil,

First of all, I want to say a huge thank you for taking the time and handling it.
I'll try to answer everything as best of my knowledge, let's hope I don't forget anything.

1. From the dump of Vid_050:

Code: [Select]

Tue Feb 19 09:26:37 2019 0 0 A 32.08812121 N 34.85583249 E 0 0 0 0 0 3.38151264190674
Tue Feb 19 09:26:38 2019 0 0 A 32.08811989 N 34.85583259 E 0 1.62999999523163 64 3.67499995231628 0 3.37774848937988
in the first line, I'm guessing that the info we have here is: longitude, latitude, elevation.
on the second line, I have no idea what are the rest of this stuff: 1.62999999523163 64 3.67499995231628

2. As far as I know, accuracy of longitude and latitude data is measured up to 7 numbers after the floating point.
here I can count 8, which means that it's accurate to about 1 meter, 7 is fine by me (accurate to about 10 meters)
for me accuracy of elevation data of 4 numbers after the floating point is also sufficient.
I don't mind the extra accuracy, but just to let you know what I consider "accurate data measurement"

3. Regarding time code: I know that the video is 30 FPS, is this helping?
I don't think that the phone is sampling the GPS data every second, but I might be mistaking.

4. Regarding 0x101:
Yes, IXE3518NYGDB3N is the camera S/N.
Insta360 is the name of the company
One2 is the technical name of the One X (just like phones, where Samsung Galaxy S5 is SM-G900F)
V1.17.16 is my firmware version.
lines 30 and onward - I have no idea.

5. Record 0x200 also makes no sense to me.

6. Just like you said, 0x300 seems like 6 axis data to me.
I have no idea how to interpret it (what axis is what number) but I'm assuming it's in the following order:
Roll: rotation around the front-to-back axis, Pitch: rotation around the side-to-side axis, Yaw: rotation around the vertical axis
And then the next 3 numbers are from the accelerometer.
I have a friend who might be able to help a bit, I'll run it by him.

7. Regarding recorded 0x400, can it be that 96 is Fahrenheit of the phone? does it fluctuate much?

8. When looking at Vid_050 dump:

Code: [Select]

Tue Feb 19 09:26:44 2019 0 0 A 32.08812709 N 34.85585249 E 224 1.80249989032745 0 3.23828125 0 3.35669207572937
Can it be that the two 0 before the "A" is altitude? and that's why it's 0? (don't know why you got 0 twice though)
And after the "E", 224 looks like a direction to me, like SW on a compass.

9. Vid_051 is when the phone is stationary and the camera moves.
So, logicly, the speed should be 0
(because the base assumption is that the camera don't get a GPS signal, only the phone)
I've checked the video, the data I see in the app for Vid_052 at 00:00 is:
speed: 0.58 km/h
elevation: 58.33
slope: 0.0%
routh: 0.00km
direction: 293° NW
location: 32°5'16"N , 34°51'22"E

And at 00:03 (approx when I put my phone down and start walking around with the camera):
speed: 0.00 km/h
elevation: 58.33
slope: 29.7%
routh: 0.00km
direction: 0° N
location: 32°5'16"N , 34°51'22"E

I found out in the app that for Vid_050 at 00:15 I get to speed of 2.99 km/h, here is the full data:
speed: 2.99 km/h
elevation: 89.96M
slope: 100.0%
routh: 0.00km
direction: 86° E
location: 32°5'17"N , 34°51'21"E



Sorry this post got so long,
for me all of this is really an uncharted territory and this is the first time I'm dealing with this kind of a challenge
Thanks again

[Phil Harvey]

Great, thanks.  I'm pretty confident now that I'm extracting GPSLatitude/Longitude/Speed/Altitude/Track correctly.  Note that you must use the -ee option to extract this information.

I've just released ExifTool 11.28 with this update.

- Phil

[SM26]

Great!

Thanks,
I'll download the new version
and create some more test samples, we will see how it goes from there.
(so far I've only used the GUI version, so I'll probably need a day or two to read the documentation about the CMD version.)

Hello Phil,

I think I got it,
one thing I'm not 100% sure about,
I use the command: exiftool -ee -p gpx.fmt Vid_052.insv > Vid052.gpx

And I've used the GPX.FMT file from here:
https://www.exiftool.org/geotag.html#GPX

currently I see: longitude, latitude, elevation.
Should I modify the FMT file somewhat?
just want to make sure I'm not missing out on any data available.

Just found this little gem:
https://exiftool.org/forum/index.php/topic,5095.msg46514.html#msg46514
do we have some gyro data to add to the FMT file like so; "ACC $framenumber $accelerometer" ?

Thanks in advance.
