Re-read metadata from a sidecar for mp4

[Andrey Goreev]

Thank you Menu.
I did see ratings being shown for some video in my collection however when I did a test on a clean database it did not show up. Take a look at the very end of the second video I uploaded on YouTube.
Is there another way to read from sidecars ? I tried menu - item - reread metadata from image

The XMP handling for videos has improved in v5.7.0+, but from my testing it is still not reading in some metadata such as captions and tags. This has been reported: https://bugs.kde.org/show_bug.cgi?id=375570

Actually no, I am not sure why digikam created an extra filename.xmp for a file that had filename.ext.xmp but I cannot reproduce it now.
Anyways, looks like "Reread metadata from Image" simply trying to read metadata embedded in the file and ignores the sidecar.
Cannot load metadata from file   (Error # 11 :  /mnt/data/FamilyPictures/2015/2015-12-25/20151225_071652.mp4: The file contains data of an unknown image type

I think this can be improved. There should be a way to set priority between 1.database 2.embedded metadata 3.sidecar for each file type (1. jpegs, 2. raw images, 3. video files) when user re-reading metadata. Having a separate option "Reread metadata from sidecar" might help too.

I just found out that digikam 5.8.0 creates sidecars named filename.xmp vs. digikam 5.0.0 that was naming them filename.ext.xmpCan this behavior be reversed?

I also noticed that if there is a star rating specified in the xmp sidecar digiKam does show it. But it ignores the tags (keywords)...

Hello
I have noticed that some tags for my video files (mp4) disappeared from database.I do see xmp sidecars though and if I open them in Kate I am seeing my tags there. 

I tried selecting a video "Menu - Item - Reread Metadata from Image" but it does not bring my tags back.
I am wondering if there is a way to bring the tags from sidecars back to database.
digiKam set to read/write to/from sidecars for read-only image only.

Best regards, Andrey
