Hi,
I'm having some issues with the text extraction with our fresh 1.2
installation.
I keep getting the following error:
2011-10-13 13:03:31 WARN (TextAnalyzerServiceImpl:229) - Error
extracting text from
http://ic**.ugent.be:8080/files/collection/composer/550.tif

This error is repeated a number of times in the log. The text extraction
does not fail for every image, just for some images, but as a result the
recording
has the status failed with following error :
org.opencastproject.workflow.api.WorkflowOperationException:

extraction failed on images from
http://ic**.ugent.be:8080/files/mediapackage/5952f751-e8f9-41e5-b55d-7002ca31a67b/8fd9ca3d-cfbc-429a-a035-2ddcbf608412/logica_trimmed.avi
These are tests with manually uploaded files, not sure if this could be
a factor why it fails?
Thanks
