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
|
|
|
|
NOTE: The build has been tested with FFMpeg version 3.1.0, and Tesseract 3.04.
