Thank you @kajuna for the great help. We managed to extract data using the method you described.

 

Does anyone know what is the units for the accelerometer datas from the GoPro please ?

 

this is an exemple of the extracted data:

 

HOUR,DATE,TIMESTAMP,LATITUDE,LONGITUDE,GPS_SPEED,MAGN_X,MAGN_Y,MAGN_Z,ACCEL_X,ACCEL_Y,ACCEL_Z,GYRO_X,GYRO_Y,GYRO_Z,TEMPERATURE,PRESSURE,ALTITUDE

I think they're m/s2 (metres divided by seconds squared)

Thank you @kajuna. What about gyroscope units ? :)

I've posted the source of my data extracting tool here, in case anyone wants to contribute:

Thank you for your great help. I'm really impressed by the video you made playing with GoPro sensors at PortAventura. Good Job ๐Ÿ‘

Re: Extracting the metadata in a useful format

Has anyone tried extacting data form Hero6 or Fusion cameras? I believe it won't work straight away, as they include new fields. If I can get my hands on sample video files I will at least make the extraction tool skip those so that the currently available data can be extracted on those cameras too. Understanding those new fields would take me more time.
