Problem tagging jpeg written by DxO

[tichel]

Hi.

I have a JPG that was written by the tool DxO:
http://www.mytracks4mac.info/tmp/DSC_5889_DxO.jpg

I try to write GPS tags to this file but I get the following error:

exiftool -m -codedcharacterset=UTF8  "-GPSLatitudeRef=N" "-GPSLatitude=51.717289N" "-GPSLongitudeRef=E" "-GPSLongitude=8.753553E"    "/Users/tichel/Downloads/DSC_5889_DxO.jpg" -o "/var/folders/_x/cz4_hpt13wb2xk3xrl6p9z8w0000gn/T/info.stichling.myTracks/exiftool.img"
Error: Error reading ThumbnailImage data in IFD1 - /Users/tichel/Downloads/DSC_5889_DxO.jpg
    0 image files updated
    1 files weren't updated due to errors

I tried that with exiftool 8 and 9 but get the same error.

Is this a bug in exiftool or in DxO?

Thanks,
Dirk

Hi Dirk,

DxO is well known for metadata problems.

You can use ExifTool to repair the metadata.  See FAQ number 20 for details.

Hi,

the question is why other applications do not have problems writing exif-data to files generated by DXO

Best regards

Hi Georg,

If they don't have problems writing to this particular file it is because they don't validate the metadata very well.  Either that, or they don't care about loss of metadata.
