[Digikam-users] DNG-KIPI problem, causes loss of files. Linux 64bit quad-core

[Peter Mc Donough]

Hi,

I recently converted 241 Olympus-RAW files (ORF) with the help of the 
DNGkonverter into DNG-files.

DNG-Bildkonverter - Version 2.6.0 /KDE 4.8.5 (release 2)
System Opensuse 12.2 64bit, quad-core processor.

It went reasonably quickly, all 4 processors were employed.
I got 241 dng files, no surprises here.

When I checked the result with digikam, I had 482 RAW files, but not 
only doublets, there were also some triplets and some single pictures, 
some DNGs were missing.

After some experimenting I found that a conversion file by file resulted 
in doublets, as it should.

Marking all and sending them to DNGkonverter causes loss of files.

The same procedure in Digikam, the same results.

Below is a conversion I did with 10 ORF-RAWs to DNG in two different 
directories. Ten because I wanted to make sure all processor cores were 
used.

If you look for example at the first file "P9242680.dng" you see that 
the file size is different depending on which conversion method you choose.

It also means that it is a completely different picture despite the same 
file name. Something you definitely do not want when doing a conversion.

Any ideas?
Peter
