12.65 suppressing duplicates from different groups?

[ekornblum]

This is a command I've run for past versions of exiftool:
exiftool -t -f -G -XMP:Source -IPTC:Source file_to_check.jpg
(-t for tab delimited output, -f to force printing of all tags even if no values, and -G to print the group name)

With 12.62 and before it was correctly (or what I think of as correctly...) showing both values:

Code Select Expand

XMP Source John Doe
IPTC Source John Doe
But with 12.65 it's not showing the IPTC Source value. Here's the output we get:

Code Select Expand

XMP Source John Doe
Is this because 12.65 considers the IPTC one a duplicate, even though it's in a different Group (IPTC) than the XMP one?

And if I add the -a option to allow duplicate tags to be extracted, it does show the IPTC Source, but then it's displaying that twice:

Code Select Expand

XMP Source John Doe
IPTC Source John Doe
IPTC Source John Doe
(is it even possible that there are actually 2 IPTC Source tags in the file?)

Is this a bug in 12.65? If not, is there any way that I can get 12.65 to act like it did in previous versions where it would show the 1 tag for each group?
Any help greatly appreciated!

Thanks

I can replicate it here.  I tried removing each option to see if that changed anything and it did not.

C:\>exiftool -XMP:Source -IPTC:Source y:\!temp\Test4.jpg

C:\>exiftool_12.64 -t -f -G -XMP:Source -IPTC:Source y:\!temp\Test4.jpg
XMP    Source    XMP:Source
IPTC    Source    IPTC:Source

(is it even possible that there are actually 2 IPTC Source tags in the file?)

Yes.  Some badly written software can do that.  I have a file that has five separate IPTC blocks and I've seen up to seven before.

Use the command in FAQ #3 and there should be a number for each block

C:\>exiftool -G1 -a -s -ApplicationRecordVersion  Y:\!temp\!Odd_Metadata_Chunks\0419113238478_086_Five_IPTC_Chunks.jpg
[IPTC]          ApplicationRecordVersion        : 2
[IPTC2]        ApplicationRecordVersion        : 2
[IPTC3]        ApplicationRecordVersion        : 2
[IPTC4]        ApplicationRecordVersion        : 2
[IPTC5]        ApplicationRecordVersion        : 2

Hi StarGeek,
Thanks for looking into this.

I'm running on MacOS Monterey 12.6.8, and I think I'm on Python 3.8.1 if that matters.
Exiftool is working as I'd expect it when using versions 12.55 and 12.62, but I see the problem when running 12.65.

I haven't used the -G# group number commands as I'm not interested in seeing the "extra" tags (I just want to see a single value for XMP:Source and a single value for IPTC:Source as I would get when using the earlier versions of exiftool).

So am I correct in assuming that this is a bug in 12.6.5 and that I should be able to see a single XMP:Source value and a single IPTC:Source value using the options I have in previous versions (-t -f -G)?

Thanks much
Eric

Thanks for this report.  I'll look into it.

Found the problem.  This only affects 12.65 and will be fixed in 12.66.

Thanks so much for the report!

I'm running on MacOS Monterey 12.6.8, and I think I'm on Python 3.8.1 if that matters.

Exiftool is written in Perl, not Python.  And I use the Windows "executable", so it was affecting that as well.

Thank you both!
