Overview
========
Subtitles which are burned into the video (or hard subbed) can be extracted using the -hardsubx flag.
The system works by processing video frames and extracting only the subtitles from them, followed
by an OCR recognition using Tesseract.

Dependencies
============
Tesseract (OCR library by Google)
Leptonica (C Image processing library)
FFMpeg (Video Processing Library)

Compilation
===========

Linux
-----

Make sure Tesseract, Leptonica and FFMPeg are installed, and that their libraries can be found using pkg-config.
Refer to OCR.txt for installation details.

To install FFmpeg (libav), follow the steps at:-
https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu - For Ubuntu, Debian and Linux Mint
https://trac.ffmpeg.org/wiki/CompilationGuide/Generic - For generic Linux compilation

To validate your FFMpeg installation, make sure you can run the following commands on your terminal:-
pkg-config --cflags libavcodec
pkg-config --cflags libavformat
pkg-config --cflags libavutil
pkg-config --cflags libswscale
pkg-config --libs libavcodec
pkg-config --libs libavformat
pkg-config --libs libavutil
pkg-config --libs libswscale

On success, you should see the correct include directory path and the linker flags.

To build the program with hardsubx support, from the linux directory run:-
make ENABLE_HARDSUBX=yes

Windows
