When calling CCExtractor on Windows on a file with DVB subtitles (which calls the OCR), it fails to find the tessdata folder, and gives the next error:

Error opening data file ./tessdata/eng.traineddata
Please make sure the TESSDATA_PREFIX environment variable is set to the parent directory of your "tessdata" directory.
Failed loading language 'eng'
Tesseract couldn't load any languages!

When using the GUI, there is no problem.

The issue is most likely (as logged), a problem with the relative path (./tessdata) which creates issues if called from outside the installation folder.

Relevant lines:

bcfdda5f8d/src/lib_ccx/ocr.c (L91)

After investigation, this is an issue with Tesseract, not CCExtractor (see http://stackoverflow.com/questions/6950977/tesseract-change-language-file-location for example). Closing.
