Ok so, after retesting, rebuilding the DB etc, I am not even able to confirm my initial findings are stable. What tags, keywords and face data can be understood by Qumagie or Qphoto? MS XMP face region used by MS Photo Gallery.Ĭan the face recognition data be re-used by Qumagie or Qphoto? We have photos having following face recognition data: It looks like the image description in qphoto is not the imagedescription exif of the photo, and that we need to edit something else inside the db directly. What is not working is showing the exif description back into qphoto

Then you can check with any other tool the exif value of the target file.īasically the part fetching data from qnap into a file matching the photo names and the related face tags work 100%.Īlso writing to exif works 100% but I need someone more expert to validate that the exif tool code makes sense. Just make sure you don’t drop or delete anything in mariadb, and better, backup the db files somewhere else first. Then we touch a file there, we'll need it for later codeĮlif_ifelse wrote:You can use any stock or personal picture, testing is harmless if you delete everything except one photo in qumagie_sql_faces_run.txt.
(path could be different depending on your OS). On ubuntu, create with mariadb a database qumagie, so that a folder is generated into /var/lib/mysql/qumagie
#DO I WANT TO SAVE METADATA IN DIGIKAM INSTALL#
To do all this I use a headless odroid ubuntu server on the LAN (headless = do not ask me to install Digikam or experimental tools like Photonix pls - this thread is to work around a limitation of qnap and still use qnap apps).įor completeness: when below I refer to "ubuntu", I mean 20.04 LTS server for odroid delivery by Hardkernel, but it should be the same for everyone. If qumagie is disabled I cannot see People data in qphoto.Įxtract faces from the db using MariaDB and push them to the exif tags.Īs I am pretty new to exif I will just concatenate all of them and put them in the ImageDescription (if you find a better way that is also visible by qphoto let me know). I have a ts-230 that is stretched to the max, I cannot afford to run qumagie 24x7 with container station and everything but still like qnap's interface and qphoto app and links to qcontactz to pair images. qphoto) read them while qumagie is disabled. This is not about backing up the qumagie db, it is about pouring the db into image exif and have apps (e.g. I will start showing what seems to work for me and would like others to add to that if they can. The goal of this post is discuss practical solutions to the fact that face or object tags and thumbnails are not saved to files by qnap qumagie.
