Originally created by @sparksh on GitHub (Nov 20, 2023).

CCExtractor version: 0.96
Windows 11 version 22H2

I installed version 0.96 using the .msi installer.
I want to extract hard-coded subtitles.
I enabled HardSubx from the HardSubx Settings.

On the first try, there appeared to be missing dependencies:

    "eng.traneddata not found! No Switching possible"

I tried creating a "tessdata" subfolder and copying eng.traneddata from the September 15, 2017 version.

Trying an extraction again, I got only this message:

   [Boilerplate]
    ----------------------------------------------------
   HardsubX (Hard Subtitle Extractor) - Burned-in subtitle extraction process

There are countless ways to install things like tesseract, ffmpeg, etc. on Windows. Have I overlooked a write-up on how to make ccextract work on Windows?

Thanks!

Thank you for reporting this. You've identified a real issue with our Windows release packaging.

What we found:

The Windows build IS compiled with HARDSUBX support (ENABLE_HARDSUBX and ENABLE_OCR are defined), and our build system uses vcpkg to install Tesseract, Leptonica, and FFmpeg during compilation. However, the release package (CCExtractor_win_portable.zip) is missing the Tesseract runtime files:

No Tesseract DLLs
No Leptonica DLLs
No tessdata/ folder with eng.traineddata

This means HARDSUBX is compiled in but can't actually run because the OCR engine files aren't bundled.

Workaround until we fix this:

Install Tesseract OCR for Windows from: https://github.com/UB-Mannheim/tesseract/wiki
Set the TESSDATA_PREFIX environment variable to point to Tesseract's tessdata folder (e.g., C:\Program Files\Tesseract-OCR\tessdata)
Make sure the Tesseract DLLs are in your PATH or in the same folder as ccextractor

What we're doing:

We're tracking this as a high-priority bug to fix the Windows release packaging so that HARDSUBX works out of the box. We'll update this issue when the fix is ready.

Thanks for your patience!
