DK 6.4.0 appimage

I'm currently using it to store my photos located on
/dev/sdb/ ==> mounted as /photos and it works. Thank you to the team
for all the hard work.

I have another physical drive /dev/sdc/ ==> mounted as /videos

I have a whole bunch of videos: mp4, mkv...that I'd like to catalog
with DK.

1. How do I add the 2nd path?
2. Do I need to do something else for the videos?

Thank you

on 1)    isn't that Settings -> Configure Digikam -> Collections -> Add
Collection

on 2) digikam  seems to be able to view my MOV, AVI, MP4,  - guess you
can add tags /captions to find them back later

I completely forgot this. I did it a few years ago for the photos.

That's the plan for the rest of the "lockdown".

In my part of the world, we don't have an actual lockdown, just a "try
to keep social distancing". Most stores are closed. But the provincial
government has deemed carpet cleaning an essential service. Same for
bicycle stores, gutter cleaning, car washing....

Thank you

Like you, I also use the lockdown to re organize my digikam mess, not just moving albums, but captioning them.

Remember to enable saving metadata to sidecars (xmp) so you can save your
tags/captions/dates for the videos.

I prefer to save everything in the photos, yes, this means the original is no more.

Album captions is another story. Back from the Picasa days I had those in a .caption type file.

However , I didn't know about the xml option, will see if that solves my problem

Yes, I do that too, but I think you won't be able to save the changes in the
video files themselves, you need sidecars. You can enable the option to
enable sidecars for read-only files, so info will still be saved in the
pictures, but in sidecars for videos.

Just to be more precise technically : video metadata are read only and
handle with ffmpeg. Metadata extraction is limited.

We cannot use Exiv2 library here to manage video metadata. Exiv2 has
started few year ago to support video files, but code is very bugous
and not the feature is optional and will be removed in the future (as
i seen in developer thread on the project).

So, do not ask to have a better metadata support than XMP sidecar to
populate new properties. The only real solution is to revival the
Exiv2 video support (read/write), and this must be discussed with
Exiv2 team...

The alternative is to ask to ffmpeg project to improve at least the
video read metadata support.

what do you do about the album captions?

I have a new 2nd approach.  Use case:  sometimes it's just faster to do
something like

      cd /Photos

      find   .    -name    .caption | xargs   grep   -i   garden

if that list is short, and memories come back, you can quickly xdg-open
that folder and browse. Sometimes that saves having to open an expensive
application like Digikam.  Of course i don't type that horrible command,
I have a script that hides the complexity, viz.

     albums  /Photos   garden

But for this, i needed a script that saves album captions to the
.caption files. It may seem redundant and dangerous, but sometimes bare
unix tools beat the big guns.

Now, you lost me guys.

Currently I use only photos and my current settings are:

* read from sidecar: on
* write to sidecar: on
        * write to xmp sidecar only
* use compatible filename for writing sidecars: off

and I get abc_1234.cr2.xmp  That's what I want to keep.

I have abc_1234.mp4 and I want my descriptions/tags stored in
abc_1234.mp4.xmp and in DK.

Will these settings work with videos?

Thanks

Yes, that should work. But note that, for pictures, the metadata won't be
modified inside the picture itself, just in the sidecar.

also, if you need the filename to be named abc_1234.xmp instead of
abc_1234.mp4.xmp (e.g. so they are compatible with Lightroom), check the
"use compatible filename for writing sidecars" option. Otherwise, it's fine
as it is.

Perfect, these are raw files

Curious:

That setting exist in my DK 6.4.0, but I don't see it in the doc

https://docs.kde.org/trunk5/en/extragear-graphics/digikam/using-setup.html

Thanks

Hi,

Because the DK handbook need a huge update...

All help is welcome. This do not require programing skill.

I wouldn't mind lending a hand. It must be like editing Wikipedia articles.
Is there a guide of style or something I should read before I start?

Hi,

The handbook is written using docbook language, an XML based syntax.

All is explained on KDE project :

https://community.kde.org/Get_Involved/documentation

But the main structure of the documentation is already here. Fixing or
add new text sections do not require an high skill level for this
language.

All the documentation is hosted in a dedicated git repository :

https://invent.kde.org/kde/digikam-doc

This is the main entry for the file format introduction in handbook :

https://invent.kde.org/kde/digikam-doc/-/blob/master/digikam/intro-imageformats.docbook

And this is the result converted in HTML :

https://docs.kde.org/trunk5/en/extragear-graphics/digikam/using-imageformats.html

So to contribute to handbook, create a gitlab account, fork the
digiKam handbook repository, patch files, and create a Pull Request
for an official integration of changes...
