XDFBrowser

A GUI application for viewing and editing XDF (Extensible Data Format) files. XDF is a multi-modal, multi-rate time series format used in the Lab Streaming Layer ecosystem.

Pre-built Windows binaries are available from the Actions tab (select the latest successful run on master and download the artifact).

Features

• Browse all chunks in an XDF file (file headers, stream headers, samples, clock offsets, boundaries, stream footers)
• Inspect and edit the text content of header and footer chunks
• Memory-efficient: defaults to a 50 MB working set regardless of file size, loading sample data on demand

Building

Requirements:

• CMake 3.16+
• Qt 6.3+ (Widgets module)
• A C++11-capable compiler (MSVC 2019+, GCC, Clang)

cmake -S . -B build -DQt6_DIR=<path/to/Qt6/lib/cmake/Qt6>
cmake --build build --config Release
cmake --install build --config Release --prefix install

On Windows, deploy the Qt runtime after installing:

windeployqt --release install/XDFBrowser.exe

The install/ directory will then contain a self-contained, redistributable build.

CI

GitHub Actions builds a Windows x64 package on every push to master and on v* tags using Qt 6.8 LTS. See .github/workflows/build.yml.
