TSDuck is a free, open‑source reference framework for MPEG transport streams, widely adopted in digital television and video‑streaming pipelines. Engineers use it for test, monitoring, integration and debugging across DVB, ATSC, ISDB, ASI and IP‑multicast environments. The toolkit can acquire, transmodulate, analyze bitrates, timestamps and PSI/SI tables, and perform on‑the‑fly content injection or extraction.

Built in C++ with a modular plugin architecture, TSDuck lets developers add new features in hours. Each command‑line utility handles a single function, but they chain together for complex workflows. Bindings expose the library to Java and Python, while support for XML, JSON and binary formats covers most MPEG, DVB, SCTE and SCTE‑35 tables. It can monitor video/audio properties, crypto periods, and push bitrate metrics to InfluxDB and Grafana.

The project remains under the 2‑Clause BSD license, allowing unrestricted redistribution of source or binaries. Pre‑built packages exist for Windows, Linux, macOS and BSD, and installers are reachable via standard managers such as Homebrew, Winget or FreeBSD Ports. With active issue tracking and extensive hardware support, engineers can immediately deploy TSDuck for live or recorded transport‑stream analysis.
