LlamaCasty — License and Third-Party Notices ============================================= LlamaCasty Copyright (C) 2026 Gramps — https://llamacasty.com License: GNU General Public License v3.0 or later (GPL-3.0-or-later), with additional terms under GPL-3.0 section 7 (attribution, marking of modified versions, no trademark rights). See LICENSE and ADDITIONAL-TERMS.md, shipped beside the application. Source: https://llgit.llamachile.tube/gramps/LlamaCasty (complete corresponding source, GPL-3.0 section 6) LlamaCasty is free software: you can redistribute it and/or modify it under those terms. It comes with ABSOLUTELY NO WARRANTY. Brand artwork (the LlamaCasty name, icon, and logo files) is NOT covered by the GPL — all rights reserved; see ADDITIONAL-TERMS.md. The rest of this file lists every third-party component LlamaCasty distributes, its license, and where to get its source, so the LGPL/BSD/MIT/Apache obligations are met. Distribution obligations are NOT optional: they attach because LlamaCasty ships these components. Every license below is compatible with GPL-3.0. Note on FFmpeg (items 1-2): it used to be DOWNLOADED at first run. As of TASK 48 item 1 (2026-09-28) it is BUNDLED — the exact pinned build is fetched at BUILD time by scripts/fetch-ffmpeg.sh, verified against a SHA-256, and shipped inside the package. The product fetches no executable at runtime. 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). Bundled: ffmpeg.exe, ffprobe.exe and the libav*.dll family, unmodified, in a single `ffmpeg\` folder beside the application executable. They are the lgpl-SHARED build, so the DLLs must stay siblings of the exe — Windows resolves them from the executable's own directory. Why LGPL-shared: this is the pinned, known-good build (no libx264). Since LlamaCasty became GPL-3.0 (2026-10-09) a GPL FFmpeg build would also be license-compatible, but the pin stays: changing builds means re-verifying the encoders, and the shared build keeps compliance to this notice plus the source offer below. 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 Exact artifact ffmpeg-N-126342-gf88b741dbf-win64-lgpl-shared.zip Build tag: autobuild-2026-08-31-13-27 (variant lgpl-shared) Archive SHA-256: 46ea6521ed3877689d2ff0bd03640ac2637104415f6237d42625d13408767146 - The binaries are unmodified and the LGPL notices therein are intact. - The SHA-256 above is the integrity record for the bundled copy; it is asserted by scripts/fetch-ffmpeg.sh before extraction and re-derivable from the artifact URL in that script. 2. BtbN FFmpeg-Builds (the build system that produced the bundled binary) License: MIT (build scripts + repository) — the produced binaries are covered by FFmpeg's LGPL (item 1). Home: https://github.com/BtbN/FFmpeg-Builds 3. OpenH264 (the H.264 software fallback encoder, libopenh264) 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 is COMPILED INTO avcodec-63.dll in the bundled build above (verified 2026-09-28: the encoder is registered in that DLL; there is no separate openh264 binary to ship). So item 1's LGPL obligations apply to the FFmpeg code and Cisco's BSD terms plus its patent grant apply to the OpenH264 code inside it. This is the product's software H.264 fallback when no hardware encoder (NVENC/QSV/AMF) is available — it is deliberately not libx264, which carries no H.264 patent grant (Cisco's covers OpenH264). 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.

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. 10. Notification.Wpf + Notification.CoreUI (toast notifications, TASK 24) Copyright (c) Platonenkov and contributors License: MIT Home: https://github.com/Platonenkov/Notification.Wpf Used as: the in-window toast area (bottom-right) behind the `INotificationService` seam — non-blocking user-facing messages. Transitive dependencies (Microsoft.Xaml.Behaviors.Wpf, Microsoft.Extensions.DependencyInjection.Abstractions) are MIT, covered by item 7's .NET notice policy; this notice is kept per this file's "list everything" policy. 11. ONNX Runtime (Microsoft.ML.OnnxRuntime — runs the webcam background model, TASK 51) Copyright (c) Microsoft Corporation License: MIT Home: https://github.com/microsoft/onnxruntime Used as: the CPU inference runtime (managed package + native onnxruntime.dll) behind the `IPersonSegmenter` seam. MIT imposes no source offer. 12. MediaPipe Selfie Segmenter (landscape) (webcam background Remove/Blur, TASK 51) Copyright (c) Google LLC (authors: Tingbo Hou, Siargey Pisarchyk, Karthik Raveendran — model card "MediaPipe Selfie Segmentation", 2021-05-06) License: Apache License 2.0 Home: https://ai.google.dev/edge/mediapipe/solutions/vision/image_segmenter Source: https://storage.googleapis.com/mediapipe-models/image_segmenter/selfie_segmenter_landscape/float16/latest/selfie_segmenter_landscape.tflite Changes (Apache-2.0 §4b): converted from TensorFlow Lite to ONNX format by tools/selfie-seg/convert_tflite_to_onnx.py — float16 weights widened to float32, NHWC graph re-expressed in NCHW; the weights and the network are otherwise unmodified. Embedded in the application as selfie_segmenter_landscape.onnx. Runs entirely on the user's PC. -------------------------------------------------------------------------------- MISCELLANEOUS - The full text of every license named above is available at the linked canonical locations.
