5.4.0

not fixed
Comment 5 caulier.gilles 2016-12-23 17:05:02 UTC
Which kind of video file you use. 5.4.0 bundle use Exiv2 026-svn with video metadata support that must do the stuff. Do you see any GPS info in Exif metadata viewer ?

Comment 6 caulier.gilles 2016-12-23 17:06:12 UTC

Comment 7 Philippe ROUBACH 2016-12-23 17:36:25 UTC
it is not fixed

mp4 video

nothing in exif media data viewer
Comment 8 caulier.gilles 2016-12-23 17:48:16 UTC
It's abnormal. MP4 must be supported by Exiv2 0.26-svn.

Please report this problem to Exiv2 bugzilla. Share MP4 file for investigations.

Thanks in advance

As i said, something is wrong in Exiv2 0.26. It report nothing in Exif.

Only XMP. There is no GPS metadata inside XMP. Perhaps Exiv2 don't know yet how to extract Exiv2 from this file.

Please, report this problem as UPSTREAM BUG in EXIV2 bugzilla.

... so i suspect that GPS info are registered somewhere in un-decoded markernotes.

Nothingh can be done in digiKam side. Exiv2 has all mechanisms to do this job. Please report as UPSTREAM to Exiv2 as i explain before.

Comment 13 Maik Qualmann 2016-12-23 20:51:48 UTC
I think there is no GPS data in this video. When I upload it to my Google Photo user account, Google does not show me a GPS position. I think the GPS data comes from the recorded user motion profile and Google links this data.

Comment 14 Philippe ROUBACH 2016-12-23 22:16:16 UTC

Comment 16 Philippe ROUBACH 2016-12-23 22:55:33 UTC
you have not the right to manage the album only to download the video.

i assume google photo grant my privacy and take away all about privacy.

so you don't gate the original video.

i can't upload it to bugs.kde.org because this video have a size of 22 MB

i will try to cut it and upload it.

interesting data about our problem
Comment 18 caulier.gilles 2018-03-03 08:38:17 UTC
With 6.0.0, we have now a FFMpeg low level metadata parser based on libav C API
for video files database registration.

The Exiv2 video support is not used anymore as this code is buggous and nobody
sound motivated in Exiv2 to finalize the code.

The original post for this file must be fixed now and video metadata support
with ffmpeg must be enough to populate database entries.
