Freeview UK - no subtitles detected

[akiller]

Hi all,

I'm trying to extract subtitles from Freeview recordings but no matter what options I choose it never seems to detect anything. I've tried different recordings and channels and used both your latest release version as well as compiling the latest code myself to no avail.

Here's a sample file (~12MB) recorded on a Hauppauge Nova-T https://www.dropbox.com/s/8ir9ofo03zir90h/8ooTC.zip?dl=1

And here's a log when I tried to process it: C:\Temp\ccextractor\ccextractor-master\windows\Release-Full\ccextractorwinfull.exe --gui_mode_reports -haup -autoprogram -out=srt -bom -latin1 [+input files]

Without -haup I get (well, on linux) this output - link Can you uncheck "Hauppage" switch button and try one time more?

That's interesting that it works for you. I wonder if it's a Windows issue? Without using Haup I get the same with a 0kb srt:

Are you using the full version (which includes the OCR), not the compact one?

Hi Carlos,

I was using the full version. I was also using the GUI. When I ran ccextractorwinfull.exe manually I noticed some output which wasn't in the output from the GUI:

Opening file: 8ooTC.ts File seems to be a transport stream, enabling TS mode Analyzing data in general mode Error opening data file \temp\cce\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! Creating 8ooTC.srt

Downloading eng.traineddata from https://github.com/tesseract-ocr/tessdata and putting it in tessdata/eng.traineddata now seems to have solved the problem for both command line and the GUI.

It may be worth updating the GUI to make this clear?

Thanks for your help.
