Version: 0.9 svn (using KDE Devel) Installed from: Compiled sources OS: Linux In the camera GUI, only jpg file thumbnails are shown and no thumbnails are shown in the cr2 files. This is tested with EOS 350D and 30D. Furthermore there are no image properties or exif data available when selecting the appropriate sidebars. Once the cr2 are downloaded all is well, thumbnails are visible and exif data is complete. I presume the two bugs has the same root cause, since the exif data cannot be read, the embedded thumbnail is not available either. The following error messages are produced in a shell from which digiKam was launched: digikam: Cannot parse EXIF metadata using Exiv2 digikam: [static Digikam::DImg::FORMAT Digikam::DImg::fileFormat(const QString&)] Failed to open file digikam: [static Digikam::DImg::FORMAT Digikam::DImg::fileFormat(const QString&)] Failed to open file digikam: Size of Exif metadata from camera = 20 digikam: Exif header found at position 0
Gphoto2 or USB mass storage camera? Can you reproduce this when loading from a local path? I mean, create a "Mounted camera" camera with a local path as mount point which contains some .cr2 files, and start the CameraUI. With my test .cr2 files here, all seems to work.
Canon cameras do not do Mass Storage.

It works from a card reader, the thumbnails are visible. Gerhard
Created attachment 17236 [details] Debug statements Perhaps it is a libgphoto2 problem? It seems that for those cameras, thumbnails are loaded by libgphoto2. The attached patch adds some debug statements to find out if the thumbnails are loaded successfully or not.
Yes Marcel, it's certainly a limitation in Gphoto library. In PTP mode (GPhoto2), my Dynax 5D only provide thumbs for JPEG files, not for RAW files. In UMS mode from digiKam (not using Gphoto2), no problem... Marcus, can you give us more informations about ? Why Gphoto2 camera drivers can provide thumbs with RAW files ? Thanks in advance Gilles Caulier
we currently handle only EXIF extraction from JPEGs. can you mail me the logfile of: LANG=C gphoto2 -L --debug >lofile 2>&1
Gerhard, We cannot do anything in digiKam about these problems. This is a gphoto2 Canon driver problems (all PTP Gphoto2 drivers i think). I recommend you to report this problem in gphoto2 bugzilla : http://gphoto.org/bugs Thanks in advance Gilles
