gps data format

[StanislavM]

Hi,

I've media from novatek, i supposed that it's from A119. I've tried to extract gps data using nvtk_mp42gpx.py but with no success.

Could it be someone could point the right place to get specification notes, or the description of this binary format:

Here is hex dump of gps

Here is the link to original file:

That python script, from memory, hasn't been updated to support the latest firmware versions.

Does NovaTrakt work with your file? (https://dashcamtalk.com/forum/threads/novatrakt-extract-gps-data-from-your-viofo-a119-windows.26384)
If it does, I might be able to reconvert my code back to python and provide the updates necessary for the python script.

Hi Rob,

I've checked NovaTrakt,
it' doesn't show any files

I hadn't clicked on the link to the clip before now.

That footage is not from an A119. NovaTrakt, nor the python script you found previously will not work with this footage.

Hi Rob,
I've found that gps format should be the same as for nextbase312 model,
I've added some description that i've experimentally found:

Could it be you know how can i interpret other bytes?
