[Balázs Vinarz]

https://bugs.kde.org/show_bug.cgi?id=338631

            Bug ID: 338631
           Summary: extending raw support
           Product: digikam
           Version: unspecified
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: RAW files management
          Assignee: [hidden email]
          Reporter: [hidden email]

dear developers!
please add 10bit raw image support to digikam for supporting mediatek'a android
platform raw image importing. currently just irfanview is able to open these
files, and the workflow could be quicker if we can ignore the windows log
in/out procedure.
heres a link, i made a few comments there:

digiKam already support 16 bits color depth image internally.

Raw decoder is libraw shared lib. Please report this UPSTREAM problem to libraw
team.

i think you should let it open for a more few hours. we are still discussing
and a detailed bugreport could be better.

0.17 is planned after Photokina (and support for most announced cameras). So,
October or so.

From digiKam's point of view (open()/unpack()/dcraw_process()) nothing changed.
There are a lot of internals changed, sure.

Dear Gilles,
any ideas for using the support for mediatek devices? i can compile for my own,
but compiling only libraw is not enough. can u share some links to the newest
sources?
thanks

i compiled and installed libraw package, but digikam still shows 16.0.
so libraw support mtk chipset (Alcatel OT-997D) but cant let it work. maybe i
need to recompile libkdcraw instead of libraw?

I don't know.

This kind of support is typically implemented to libraw decoder not digiKam or
libkdcraw.

Ask to libraw team for details :

Some MTK files are indeed supported. I'm not sure, that this support is
complete.

Unfortunately, these files do not contain any metadata, so the only way to
detect file contents is file size.

--- Comment #16 from Balázs Vinarz <[hidden email]> ---
Alex, i think its not a problem. I dont want to choose or autoselec files from
a pack. Just decode a few ones. Since than:
- i installed the 17Alpha4
- force removed the 16Stable
- the program still uses the libraw_r.so.10 file, so renamed the libraw_r.so.13
but digikam still not accepts it.

You cannot use LibRaw 0.17 .so instead of 0.17 .so because ABI changed.

You need to rebuild libkdcraw

Balázs,

No need to re-open this file each time. This one is closed because your whish
is not relevent directly to digiKam/libkdcraw, as RAW decoders are in Libraw.

Alex is lead developper from libraw. He will guide you to solve your problem.
