> ExifTool does not work with Tika on Windows
> -------------------------------------------
>
> Key: TIKA-4475
> URL: https://issues.apache.org/jira/browse/TIKA-4475
> Project: Tika
> Issue Type: Bug
> Affects Versions: 3.2.2
> Environment: Windows 11 with Tika 3.2.2.
> Reporter: Adrian Bird
> Priority: Major
>
> I tried to get Tika and ExifTool to work together to process some JPEG image
> files and came across a number of issues. The issues are listed here, with a
> description of what I did below:
> 1) Tika and ExifTool doesn't work on Windows
> I used the [Wiki
> page|https://cwiki.apache.org/confluence/display/TIKA/EXIFToolParser] to
> understand how to do the integration.
> Because I wasn't getting the metadata I expected, I used the '--verbose'
> option and got a Java Exception which contained this text:
> "WARN [main] 07:13:34,699 org.apache.tika.parser.external.ExternalParser
> problem with process exec
> java.io.IOException: Cannot run program "env": CreateProcess error=2, The
> system cannot find the file specified"
> The exception occurs because 'env' is not a valid Windows command.
> I tracked this down to the file
> 'org\apache\tika\parser\external\tika-external-parsers.xml' in the Tika App
> jar where the command is:
> '<command>env FOO=${OUTPUT} exiftool ${INPUT}</command>'
> This doesn't work on Windows because 'env' does not exist.
> As a test I changed the command and updated my copy of the Tika-App.jar and
> it then worked with a video file. The changed command was:
> '<command>exiftool ${INPUT}</command>'
> 2) For the same reason Tika and sox won't work on Windows
> The command is:
> <command>env FOO=${OUTPUT} sox --info ${INPUT}</command>
> Note I didn't find any information on 'sox' on the Wiki.
> 3) Looking at the file
> 'org\apache\tika\parser\external\tika-external-parsers.xml' I noticed that it
> only contains video related mime-types, meaning that I cannot use it with
> image files. The Wiki page says:
> 'EXIFTool is a wonderful tool that reads videos, images, audio and other
> media files and that extracts EXIF metadata from them.'
> I took this to mean that Tika can extract metadata form all 3 file types, but
> that isn't the case as it only supports video files.
> Given this can I suggest that the Wiki page should be updated to make this
> clear.
