TSDuck, The MPEG Transport Stream Toolkit

TSDuck users, we need your assistance to promote the project. Please read this.

TSDuck is an extensible toolkit for MPEG transport streams. It is used in digital television systems for test, monitoring, integration, debug, lab, demo.

In practice, TSDuck can be used for:

TSDuck is developed in C++ in a modular architecture. It is easy to extend it through plugins. In fact, the primary requirement for TSDuck architecture was to be able to implement any new feature within a couple of hours, which happened to be the case most of the time.

To be easily extended, TSDuck needed to be simple. TSDuck is a collection of command line tools and plugins. There is no sophisticated GUI. Each utility or plugin performs only one elementary feature but they can be combined in any order. See some sample usages.

TSDuck is also a large library to manipulate MPEG transport streams. C++, Java and Python developers can use bindings in their languages.

In short, TSDuck shall be understood as a General-Purpose Toolbox for Digital TV Engineers and not as a specialized application for production operators.

And, by the way, TSDuck is Free and Open Source.


TSDuck is open source and released under the BSD license. It is developed in C++ and designed to be portable. TSDuck is built and tested for Windows, Linux, macOS and BSD systems (FreeBSD, OpenBSD, NetBSD, DragonFlyBSD). Please see the list of useful links in the side menu.
