@eneerhut and @chrisbeddow ,
If I may barge in: my frustrations with latest ‘mapillary’ DU 1.2.8 were - in no particular order:
1/ it took in the order of 2 or 3 hours to prepare perhaps 4½k or 6k 3MB 20MP pics for upload, where the web-uploader did the job in say 20 or 30 minutes; that was on the same computer, with the same SDXC card;
2/ the DU reported in the order of 2k from a series of 4½k Hero9 black time lapse photos were without lat/lon info, even though XnViewMP was able to place those pics that were listed as lacking GPS on the (Google) map, and when zoomed in turned out it had placed them in the correct spot.
Looking at the GoPro file numbers which the DU listed as lacking coordinates noticed break between lat/lon present and absent coincided with a break in recording - for example had switched camera off when approaching a stretch of road which I had recently recorded, switched on again upon approaching another fresh stretch (one w/o pics) ; you may recall that some weeks ago added note to post concerning GoPro file written time glitch compared to GPS time recorded, but here the pics were placed spot-on, yet DU refused to upload, WU then did the job, and they ended up in the right spot.
This is purely speculative on my part : could it be that the DU looks for a ‘really clever’ GPS location, one which the Hero doesn’t always record, or where - as with the file time vs. GPS time issue there is some glitch in the Hero(9)? Bit late, and getting tired, but nagging thought that on comparing accepted / rejected pics one or two of three GPS lat/lon sets was missing in the lower part of the ExifTool dump for the rejected pics ; not sure could lay hands on those pics and that error report. The first set is approx. 60% down, and the other two are near the very bottom of the dump.
Met als immer vriendelijke groet, (with as ever friendly greeting), and pressing send, as unlikely to squeeze any more sense out of brain this late.
