Re: Extracting the metadata in a useful format

Hi Erwin,


What we actually get is kind of a burst - a package of lat/lon/alt/speed/3dspeed data itmes associated with single data-time point. Most often we get 18 samples in such packages, but occasionally 17 or 19, maybe also other amounts. Then the delta time between those packages is close to 1 second though again it can be slightly less or more. I think that the everage frequency is 1/18.0xx.

In my application I am averaging samples from single burst and giving them the TS as provided by GoPro5 - actually duration time from the beginning of the movie rounded to seconds.

If I would like to provide raw samples with timestamps I would need to extrapolate them - e.g. uniformly within the burst.
