TSNLE Open Source Licenses
Last updated: July 27, 2026
TSNLE is proprietary software, but it is built on free multimedia libraries. The GStreamer stack, GLib, and FFmpeg are licensed under the GNU Lesser General Public License (LGPL-2.1-or-later). TSNLE loads them as separate, unmodified dynamic libraries — you can identify and replace them with your own builds, as the LGPL requires. The TSNLE EULA explicitly does not restrict any of your LGPL rights.
