why this should be an exception.

CCExtractor
CCExtractor is a tool used to produce subtitles for TV recordings from almost anywhere in the world. We intend to keep up with all sources and formats.
Subtitles are important for many people. If you're learning a new language, subtitles are a great way to learn it from movies or TV shows. If you are hard of hearing, subtitles can help you better understand what's happening on the screen. We aim to make it easy to generate subtitles by using the command line tool or Windows GUI.
The official repository is (CCExtractor/ccextractor) and master being the most stable branch.
Features
- Extract subtitles in real-time
- Translate subtitles
- Extract closed captions from DVDs
- Convert closed captions to subtitles
Programming Languages & Technologies
The core functionality is written in C. Other languages used include C++ and Python.
Installation and Usage
Downloads for precompiled binaries and source code can be found on our website.
Extracting subtitles is relatively simple. Just run the following command:
ccextractor <input>
This will extract the subtitles.
More usage information can be found on our website:
You can also find the list of parameters and their brief description by running ccextractor without any arguments.
You can find sample files on our website website to test the software.
Compiling CCExtractor
To learn more about how to compile and build CCExtractor for your platform check the compilation guide.
