Hello there! Thank you for this great tool!
I'm trying to write a tool that read the telemetry track, process it and write it back in the input file.
Have you ever tried something like that?
Do you know if it's possible to mux the bin file in a mp4 video with ffmpeg?

Any suggestion would be greatly appreciated :)

So, apparently the stream handler_name has changed again in Hero6 files. And that makes automated data extraction difficult for those of us who use ffmpeg. If I'm not wrong, for Hero5 files up to 60 fps, it was something like

Stream #0:3(eng): Data: none (gpmd / 0x646D7067), 33 kb/s (default)
Metadata:
creation_time : 2017-11-25T15:46:16.000000Z
handler_name : GoPro MET

Which could be extracted via

ffmpeg -y -i VIDEOFILE.MP4 -codec copy -map 0:3 -f rawvideo DATA.BIN

Then, over 60 fps the Stream was:

Stream #0:2(eng): Data: none (gpmd / 0x646D7067), 66 kb/s (default)
Metadata:
creation_time : 2017-11-25T15:46:48.000000Z
handler_name : GoPro MET

So this call, despite the awkward tabulator character before "GoPro MET" would work for both:

ffmpeg -y -i VIDEOFILE.MP4 -codec copy -map 0:m:handler_name:" GoPro MET" -f rawvideo DATA.BIN

Now, Hero6 files don't have the tabulator character:

Stream #0:3(eng): Data: none (gpmd / 0x646D7067), 37 kb/s (default)
Metadata:
creation_time : 2017-11-21T22:25:40.000000Z
handler_name : GoPro MET

So they can be retrieved with the 0:3 of the H5 sub 60fps command, but not with the previously universal 0:m:handler_name:" GoPro MET" and 0:m:handler_name:"GoPro MET" does not work either for some reason I don't comprehend.

Does anyone know how to solve this? Maybe using regular expressions or looking for the "(gpmd / 0x646D7067)" bit?

It seems that HERO 6 last firmware (v02.01) add new labels : MTRX, ORIN, ORIO
Error reading telemetry file Could not find label in list: MTRX (4d545258)

Is it possible to manage it ?
Thanks

Based on a tweet, I think it's got camera data like EXIF including shutter speed and ISO.

Printing it out on screen as strings looks something like:

... which I don't recognize off hand, but it does have the firmware version, serial and model number of the camera, and at least cursory GPS coordinates. The rest seems meaningful and I bet matches a well-known metadata format.

Will dig.

Some files recorded on GH6/GH7 camera cannot be processed by gopro2gpx utility.
Following error occurs:

Error reading telemetry file parsing time "5457900081260100": month out of range

In the same time GoPro Quick app successfully reads GPS data from these files.
May be it just ignores corrupted records.

GH010245.ZIP
GH020245.ZIP

Please see #27 for the background information.

A further problem I'm facing are coordinate which are completely off track.

BIN file:

GX010039.bin.zip

This is the GPX track I'm getting:

GX010039.gpx.zip

The tracks looks "exploded" in a few places:

This part here is completely off the track. Quite sure I did not drive there:

Same here:

Check the "vertical" part here in the middle. Looks quite consistent. Except there's no road there and I did not drive there. Also consider the part in the upper right corner.

Also get severely inprecise coordinates along the track:

Quik shows a somewhat better looking track:

However Quik does not show almost the half of the drack I actually drove.

I don't think these "explosions" of the track can't be explained by the imprecision of GPS. Ok, I'm fine with a few meters, but I see jumps of several hundreds meters if not kilometers here. Also, this is not visible in Quik.

As someone new to GO, there doesn't seem to be a build file or instructions on how to build the project? Could you add a section on build instructions? Thank you!

About this comment

Here is the definition of DVID:

Hi
I tested it on the gopro fusion and it gives out empty cvs files.
If you want I could send you short vids for testing?

Cheers
G

ps. thanks for the app. used it already on gopro 5!

Seems like ffmpeg does not create the correct bin file when using the parameters -ss (to start extraction at a specific second) and -t (the length of video to take from the start point).
Thus it would be interesting to be able to tell gopro2gpx to trim the GPX file with the same 2 parameters instead.
./gopro2gpx -i tmp.bin -ss 20 -t 10 -o tmp.gpx
would extract the GPS starting at second 00:20 for a length of 10 seconds

Thanks for the library

I had to add labels "UNIF" & "SROT" for the Hero 7
I haven't investigated what they are for, but my data requirement is very basic - just GPS.
Will look to ignore missing additional labels at some stage when I work out the best way to do it

Cheers

Hi there,
firstly I want to thank you very much for this code. Saves me a lot of time!

Could you please explain to me what the variable 'track' in the json file from gopro2json exactly is?

Thank you very much,
Patrick

Title sais it all - that is what I get as the ouput when I follow the instructions in the README.

Here is an example gpmf file: https://drive.google.com/open?id=1uJ1DWnIqkOmAMsKQQYM0nkeJmYzEjt5g

Could you provide a sample Gopro 5 Video? :)

After cloning the repo I can not figure out how to build and run on Mac. Please include build / run instructions assuming Go is installed.

go install github.com/stilldavid/gopro-utils/bin/gopro2json@latest
did not work

When I try to run the example command, I get:

Any ideas?

I am trying to extract the UTC time from a Gopro fusion camera. I created the binary GPMD from its stream using ffmpeg. However, upon converting bin to json using telemetry I receive the following error:
**
Error reading telemetry file Could not find label in list: STMP (53544d50
exit status 1
**
this is the command I used to convert bin to json:
go run gopro-utils\gopro-utils\bin\gopro2json\gopro2json.go -i GS010805.bin -o GS010805.json

the script works on regular gorpro Hero 6 and Hero 7 videos, but not on the Fusion.
Any help is very much appreciated.

Hi,

Gopro Quik (desktop) allows edit only gopro files. (Compatible with footage captured using HERO5 Black with GPS activated.) Is there a way to create gopro video from another video? Can we create and insert some gopro data?

I think we need something similar like this:
https://support.google.com/jump/answer/7044297?hl=en

What do you think? Is it possible?

Hi, I am trying to add a hilight tag write out to the program, here is my progress. Hilight tags are time (in milliseconds) pinpoints in the video. I do not have a HERO5 to test the integration, I found this repo which reads HiLight tags and works with my HERO4 Black footage. To tag a new hilight tag press the side button during a recording or use the GoPro App.

I am trying to export a GPX track from an MP4 video filmed on GoPro 6.

Somehow I'm getting invalid coordinates. I see several problems which appear on the exported GPX track - but which I don't see on the GPS gauge in Quik.
I will create a separate issue per problem.

First problem is that I'm getting completely off-the track coordinates. Here's a example:

The video is filmed in Germany (around 8.663, 50.232). A few first points on the exported GPX track lie north of Canada (-128.4998971, 80.8641778). Also the elevation for these points is exported as 20841.167 (in reality should be around 202).

Quik seem to show this track correctly:

The complete video is ca. 3.4GB so I can't reasonably share it. I also don't know how can I cut it while keeping all the streams including GoPro MET.

Below is the .bin file I've exported from the video:

GX030039.zip

This is how I've exported it:

ffmpeg -y -i GX030039.MP4 -codec copy -map 0:3:handler_name:" GoPro MET" -f rawvideo  GX030039.bin

Below is the (zipped due to GitHub) GPX track:

GX030039.gpx.zip

Exported using:

gopro2gpx -i GX030039.bin -o GX030039.gpx

Invalid points look like:

			<trkpt lat="80.8641778" lon="-128.4998971">
				<ele>20841.167</ele>
				<time>2018-09-29T10:20:53Z</time>
			</trkpt>
			<trkpt lat="80.8641778" lon="-128.4998971">
				<ele>20841.167</ele>
				<time>2018-09-29T10:20:54Z</time>
			</trkpt>

First valid point:

			<trkpt lat="50.2319754" lon="8.6630605">
				<ele>202.121</ele>
				<time>2018-09-29T10:23:51Z</time>
			</trkpt>

TS is always 0
Function is missing. Can some one help to add that ?

Please help. How to extract data from Hero 6. What do I need to change for this?
Thanks.

Not sure why I receive:

Stream map '0:3' matches no streams.
To ignore this, add a trailing '?' to the map.
