ytLlive — Third-Party Notices
================================

ytLlive is a paid, closed-source product. This file lists every third-party
component the product distributes or downloads, its license, and where to get
its source, so the LGPL/BSD/MIT obligations are met. Distribution obligations
are NOT optional: they attach because this product ships or automates the
download of these components.

If this file changes, update it here AND in the app's About screen (the About
overlay's licensing panel surfaces this file in-app). See TASKS.md (TASK 4) and
ai.md ("Licensing — do not violate") for the guardrails — the "never do" list is
there on purpose.

1. FFmpeg  (dynamic libraries + ffmpeg.exe, LGPL v2.1+)
   Copyright (c) 2000-2026 the FFmpeg developers
   License: GNU Lesser General Public License v2.1 or later
   Home:    https://ffmpeg.org/
   Source:  https://git.ffmpeg.org/ffmpeg.git
   Used as: the streaming encoder/RTMP subprocess. This product distributes the
            UNMODIFIED binaries; it never links FFmpeg into its own code (it is
            launched as a separate process fed raw frames over a pipe).
   Why LGPL (not GPL): a GPL build (e.g. gyan.dev, or BtbN's "gpl" variant)
            would contaminate this proprietary product. Do NOT use one.
   Why "shared" (not static): LGPL v2.1 §6 requires "relinkable" materials for
            statically-linked libraries. The shared build links dynamically, so
            the user can replace the DLLs — compliance is this notice plus the
            source offer below, with no relink material required.
   Compliance supplied by this product:
     - The license text: https://www.gnu.org/licenses/old-licenses/lgpl-2.1.html
     - The corresponding source / written offer to obtain it:
       FFmpeg source     https://ffmpeg.org/download.html
       Exact binary      https://github.com/BtbN/FFmpeg-Builds
       Build tag:        autobuild-2026-08-09-13-03 (variant lgpl-shared)
     - The binaries are unmodified and the LGPL notices therein are intact.

2. BtbN FFmpeg-Builds  (the exact binary this product downloads)
   License: MIT (build scripts + repository) — the produced binaries are
            covered by FFmpeg's LGPL (item 1).

3. OpenH264  (libopenh264 — the H.264 software fallback encoder)
   Copyright (c) 2010-2026 Cisco Systems, Inc. (and contributors)
   License: BSD 2-Clause + Cisco's H.264 patent grant
   Home:    https://www.openh264.org/
   Note:    Cisco grants the patent license for its own H.264 implementation;
            it ships inside the FFmpeg build above (LGPL obligations of item 1
            apply to the library; the BSD terms apply to Cisco's code).

4. SQLite  (bundled via SQLitePCLRaw's e_sqlite3 native bundle)
   License: public domain (no rights reserved)
   Home:    https://www.sqlite.org/

5. Microsoft.Data.Sqlite  (.NET data provider, statically linked into this app)
   Copyright (c) .NET Foundation and contributors
   License: MIT
   Home:    https://github.com/dotnet/efcore

6. SQLitePCLRaw  (raw SQLite bindings + bundles)
   Copyright (c) 2012-2026 Eric Sink and contributors
   License: Apache-2.0
   Home:    https://github.com/ericstj/SQLitePCLRaw

7. .NET runtime / WPF / Windows SDK projections, incl.
   System.Security.Cryptography.ProtectedData
   Copyright (c) .NET Foundation and contributors
   License: MIT
   Home:    https://github.com/dotnet/

8. Simple Icons  (bundled SVG logo path data for the social bar, e.g. the
   mastodon/peertube/pixelfed fediverse logos)
   Copyright (c) Simple Icons contributors (public domain dedication)
   License: CC0 1.0 Universal (no rights reserved, no attribution required)
   Home:    https://simpleicons.org/
   Source:  https://github.com/simple-icons/simple-icons
   Used as: path data compiled into the app's `SocialServiceIcons` so each
            social entry renders the service's real logo. CC0 imposes no
            obligations; it is listed here per this file's "list everything"
            policy.

9. NAudio  (WASAPI audio capture — loopback + mic)
   Copyright (c) Mark Heath and contributors
   License: MIT
   Home:    https://github.com/naudio/NAudio
   Used as: the WASAPI loopback (desktop/game audio) and mic capture sources
            behind the `IAudioSource` seam (TASK 4 ship step 4). MIT imposes
            no source offer; this notice is kept per this file's policy.
