TSDuck is an extensible toolkit for MPEG transport streams.

TSDuck is used in digital television systems for test, monitoring, integration, debug, lab or demo.

In practice, TSDuck is used for:

• Transport stream acquisition or transmodulation, including DVB, ATSC, ISDB, ASI and IP multicast.
• Analyze transport streams, PSI/SI signalization, bitrates, timestamps.
• Monitor and report conditions on the stream (video and audio properties, bitrates, crypto-periods, signalization).
• On-the-fly transformation or injection of content and signalization.
• Modify, remove, rename, extract services.
• Work on live transport streams, DVB-S/C/T, ATSC, ISDB-T, ASI, UDP ("IP-TV"), HTTP, HLS, SRT, RIST or offline transport stream files.
• Use specialized hardware such as cheap DVB, ATSC or ISDB tuners (USB, PCI), professional Dektec devices, cheap HiDes modulators, VATek-based modulators (e.g. Suntechtv U3, USB).
• Re-route transport streams to other applications.
• Extract or inject Multi-Protocol Encapsulation (MPE) between TS and UDP/IP.
• Analyze and inject SCTE 35 splice information.
• Extract specific encapsulated data (Teletext, T2-MI).
• Emulate a CAS head-end using DVB SimulCrypt interfaces to and from ECMG or EMMG.
• And more...

TSDuck is developed in C++ in a modular architecture. It is easy to extend through plugins.

TSDuck is simple; it 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.

Through tsp, the Transport Stream Processor, many types of analysis and transformation can be applied on live or recorded transport streams. This utility can be extended through plugins. Existing plugins can be enhanced and new plugins can be developed using a library of C++ classes.

TSDuck comes with a comprehensive User's Guide.

All utilities and plugins accept the option --help to display their syntax.

For programmers, TSDuck provides a large collection of C++ classes in one single library. These classes manipulate, in a completely portable way, MPEG transport streams, MPEG/DVB/ATSC/ISDB signalization and many other features. See the programming guide and its tutorial.

Python and Java bindings exist to allow running transport stream processing pipelines from Python or Java applications.

TSDuck can be built on Windows, Linux, macOS and BSD systems (FreeBSD, OpenBSD, NetBSD, DragonFlyBSD). See the building guide for details.

• On macOS, use the Homebrew packager: brew install tsduck
• On Windows, use winget: winget install tsduck

Pre-built binary packages are available for Windows and the very latest versions of some Linux distros (Fedora, RedHat, CentOS, AlmaLinux, Ubuntu, Debian, Raspbian).

The latest developments can be tested using nightly builds.

The command tsversion --check can be used to check if a new version of TSDuck is available online. The command tsversion --upgrade downloads the latest binaries for the current operating system and upgrades TSDuck.

TSDuck is maintained by one single developer on spare time and on personal expenses. You may consider contributing to the hardware and Web hosting costs using
