Description Reiner Nix 2011-04-02 12:32:38 UTC

Version:           1.2.0 (using KDE 4.4.5) 
OS:                Linux

Scenario:
My computer is acting as DLNA server (using coherence) to export the images allowing them to view on my great flat panel television. Unfortunately the television just displays all images without considering tags, rating and so on.

So I have to display through the whole album. On the other side digikam as the great feature to set up searches which can be configured over a wide range of attributes.

Wish:
It would be great if digikam can materialize a search by creating a "virtual album". I.e. it should create a folder in a specified location and puth the images to it by linking them. (I guess that using soft links would be sufficient.) In this way, I could view the images as specified by the search in digikam using any other program, i.e. when exported by a DNLA server.

Of course I guess that images within the virtual albums should not be placed as duplicates into the database.

Reproducible: Didn't try




OS: Linux (i686) release 2.6.32-5-686
Compiler: cc

It will be more logic to have a DLNA interface for digiKam ?

Comment 2 Reiner Nix 2011-04-04 08:41:01 UTC

I guess that adding a DNLA interface would require more logic. DNLA is based on top of a Universal Plug and Play and allows to access and export media data. Probably digikam can provide a plugin for an existing DNLA software. 

On the other hand the DLNA interface provides access to the media but as far as I can see, it not necessarily establishes a wide user interface, e.g. to defines queries. So I guess that another way could be that digikam could interface DNLA by creating a plugin which for each already defined query exports a "virtual album", i.e. without creating a folder on filesystem with links to the images.

Having a folder with links would have the benefit that this is based on well proven OS mechanism and visible to all other kinds of applications.

I shall have a look at coherence. For my needs, I would like to have digikam an integration with coherence, so that a presentation on the TV can be started and possibly even controlled from within digikam. Not sure if this is possible with the available DLNA stack.

Smit,

I reassign this entry to your DLNA Export tool since it will be available for 3.0.0 as a kipi plugin. We will not introduce a DLNA interface into digiKam core...

Hi Reiner

You can try out digikam 3.0.0 when it launches (near christmas), or if you are comfortable compiling it on your own, digikam-3.0.0-beta2 tarballs are already available. A kipi-plugin named DLNA export has been included in it. Although, since its a kipi-plugin and not embedded into digikam core, it doesnt allow to group images over all the dimensions which Advanced Search Tool provides, but it gives tags, digikam's collection and their hierarchy. We have taken this decision to allow usage of the plugin by other KDE products like GWenview, etc. So for now, i am closing this bug. You can file a bug, if you find any problems with the existing DLNA export, only after digikam-3.0.0 stable releases. Currently it is still under development.

The tool to export collection through DLNA media server was fully re-written with next 5.8.0. The server is now based on Platinum SDK (same used in Kodi media center), and work fine under Linux, Windows, and MacOS.
