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.

WebVTT Output Options

CCExtractor supports optional WebVTT-specific headers for advanced use cases such as HTTP Live Streaming (HLS).

--timestamp-map

Enable writing the X-TIMESTAMP-MAP header in WebVTT output.

This header is required for HLS workflows but is disabled by default to preserve compatibility with standard WebVTT players.

Example:

ccextractor input.ts --timestamp-map -o output.vtt

Windows Package Managers

WinGet:

winget install CCExtractor.CCExtractor

Chocolatey:

choco install ccextractor

Scoop:

scoop bucket add extras
scoop install ccextractor

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:

• Using the command line tool
• Using the Flutter GUI

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 to test the software.

Building from Source

• Building on Windows using WSL

Linux (Autotools) build notes

CCExtractor also supports an autotools-based build system under the linux/ directory.

Important notes:

• The autotools workflow lives inside linux/. The configure script is generated there and should be run from that directory.
• Typical build steps are:

cd linux
./autogen.sh
./configure
make

• Rust support is enabled automatically if cargo and rustc are available on the system. In that case, Rust components are built and linked during make.
• If you encounter unexpected build or linking issues, a clean rebuild (make clean or a fresh clone) is recommended, especially when Rust is involved.

This build flow has been tested on Linux and WSL.
