            Bug ID: 378929
           Summary: DNG conversion fails in Windows 10 for Olympus ORF
                    files
           Product: digikam
           Version: 5.5.0
          Platform: Other
                OS: MS Windows
            Status: UNCONFIRMED
          Severity: critical
          Priority: NOR
         Component: BatchQueueManager-Tool-RAWProcessing
          Assignee: [hidden email]
          Reporter: [hidden email]
  Target Milestone: ---

ORF to DNG conversion do not work in Windows version. Only thumbnails are
visible and most of time makes digikam unusable (it freezes) and delete those
DNG is mandatory to make digikam or showfoto work again.
At ubuntu works fine and files are readable even in Windows version.
I use it in Windows 10

It will help to see the debug statements printed by digiKam will it running.
You need debugview tool from Microsoft for that. There is no reason to see a
difference between windows and Linux to process DNG files. It low level code
using standard fonctions.

I suspect a file system access problem, as long file names or UTF8
compatibility.

I've tried in other computer with windows 10 and fresh DigiKam installation;
the problem persists.
It only shows the thumbnail and when you to open  DNG file the only thing you
get it's a black image.(in some cases very localized spots like noise)
It's only for Olympus ORF files, I've tried with Minolta MRW and works well.
(sorry I've not other raw files to test and I don't know about programming

The converted DNG in DigiKam shows a very tiny strange simbols in title where
in well converted DNG in linux shows "OLYMPUS CAMERA". It seems as if something
were corrupted

Here:

http://cybergrix.net/grix/orfdng/

you can get 5 files
the original orf file
the corrupted dng and the properly converted one in linux
 and two screenshot that shows how both thumbnails are shown in DigiKam (note
the small simbol that appears in the title of the corrupt version)

Thanks

Thanks for the test image. But also with this ORF image I can not reproduce the
problem under Windows7. I will check the days it under Windows10.

I confirm that problem is not reproducible here with Windows 7.

Q: Do you use a special path scheme name to host ORF files, as non latin1
characters ?

No, in the fresh installation I used a new created directory in the same unit.
I'll try to test in windows 8.1 later

Installed new version (13-Jun-2017 05:44)
Still not working in windows 10 pro 64
works perfectly on linux bundle
When the image is properly converted the photo footer should show "OLYMPUS
IMAGE CAMERA". In windows version there is no footer
Lightroom works in the same computer and writes the footer "OLYMPUS IMAGE
CAMERA" and conversion is good
I have tested in other computer with windows 10 home 64 with same result. Image
is black and only thumbnail can be seen. There is no "OLYMPUS ... " footer

any ideas ? is there anyone that can test in windos 10 ?

thanks

Guillermo Munoz

P.D.linux bundle is (in my opinion) much safe and better way for distribute
programs
is there a bundle for windows ?

Look like bug #381432 is exactly the same than this one. There is a trace of
DNG convert while running under Windows 10.

I make this file as duplicate of #381432
