Third-party notices

TeleTool contains and interoperates with third-party software. TeleTool’s proprietary licence does not replace or restrict the licences below.

GStreamer NDI® plugin

TeleTool’s Debian package contains gst-plugin-ndi version 0.13.5 from the GStreamer gst-plugins-rs project.

• Licence: Mozilla Public License 2.0 (MPL-2.0)
• Corresponding source: https://static.crates.io/crates/gst-plugin-ndi/gst-plugin-ndi-0.13.5.crate
• Upstream project: https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs
• Source archive SHA-256: ec8417e75002857f4c8e8fd2f2f1a7521937eaac3de264f7bb6904a0d22cba23
• Licence text: https://www.mozilla.org/MPL/2.0/

The exact source archive and the licence files for Rust packages compiled into libgstndi.so are included in the Debian package under /usr/share/doc/teletool/third-party/.

The plugin was initially developed by Teltek and funded by the University of the Arts London and the University of Manchester. Its upstream acknowledgements also credit Sebastian Dröge and the other GStreamer contributors.

NDI runtime and trademark

The proprietary NDI runtime is not distributed as part of TeleTool. It must be obtained separately by the user from https://ndi.video/ and remains subject to the NDI SDK licence applicable to that download.

NDI® is a registered trademark of Vizrt NDI AB. TeleTool is an independent project and is not affiliated with or endorsed by Vizrt NDI AB.

Optional Inferno-AoIP interoperability

TeleTool can detect and use the optional teletool-inferno companion package as a network audio output. The main teletool Debian package does not include Inferno-AoIP source code, binaries, ALSA modules, Statime builds, service files, or configuration. The separate teletool-inferno package is published in the same signed TeleTool APT repository and includes a pinned upstream Inferno ALSA PCM, a pinned Inferno Statime fork build, service configuration, and corresponding source/licence material under /usr/share/doc/teletool-inferno/.

• Licence: GNU General Public License v3 or later (GPL-3.0-or-later) or GNU Affero General Public License v3 or later (AGPL-3.0-or-later), at the user’s option under upstream terms
• Upstream project: https://github.com/teodly/inferno
• Primary upstream repository: https://gitlab.com/lumifaza/inferno

Inferno-AoIP is an unofficial Dante-compatible implementation and is not affiliated with or endorsed by Audinate. TeleTool’s proprietary licence does not replace, narrow, or grant rights to Inferno-AoIP.

Separately installed dependencies

TeleTool uses FastAPI, Uvicorn, Pydantic, Requests, urllib3, PyGObject, GStreamer, Tvheadend, Avahi, FFmpeg-related GStreamer components, ALSA, and other packages supplied separately by Python or Raspberry Pi OS/Debian. Those packages retain their own copyright and licence terms; their installed package documentation contains the corresponding notices.

Tvheadend, GStreamer, Raspberry Pi, Python, FastAPI, and other product names are the property of their respective owners. Their mention describes compatibility and does not imply endorsement.
