Hotfix Notice - May 20, 2026

The Windows installer asset was replaced after the initial v2.1.9 upload to fix a laptop startup issue where the process could close before the UI or desktop launch log appeared.

Current installer SHA-256:

AF804BE93D95A254930E1CFDDCFBA5EA955DFB04A07FCDCB6BC94EF4A7B0B334  DeepLiveCamStudio-2.1.9-x64-setup.exe

After installing, DeepLiveCamStudio.exe should have SHA-256:

D38DE56BE5162D164F6048FFB08D8B36F1DAD8578E1B918907C758120DDE3DE8

If you downloaded v2.1.9 before this notice, download the installer again.

Source And License

Deep-Live-Cam is licensed under AGPL-3.0. This binary release is distributed with corresponding source availability requirements.

Attach the source archive listed above to the GitHub Release, or link the exact release tag/commit in the publishing repository. The public release must make the complete corresponding source available for the exact binary installer.

The source archive must be produced from the release Git ref with:

powershell -ExecutionPolicy Bypass -File build\windows\package_source.ps1 -AppVersion 2.1.9 -GitRef c676426c8eb8f1bd61d17439eece02d2426065bd

This release preserves attribution to the original project:

Models Are Not Bundled

The installer intentionally does not include model/checkpoint files (.onnx, .pth, .safetensors) because model licenses and redistribution rights are separate from the application license.

After installing, users can review model sources, license notes, and SHA-256 checksums before downloading:

DeepLiveCamStudioCLI.exe --download-models

Downloaded models are stored under:

%LOCALAPPDATA%\DeepLiveCamStudio\models

Notable Packaging Changes

  • Windows x64 per-user installer using Inno Setup.
  • PyInstaller onedir app bundle; Python does not need to be installed by users.
  • Start menu shortcut and optional desktop shortcut.
  • Clean uninstall of app files; user model data is preserved during silent uninstall and interactive uninstall asks before removing models.
  • WebP and AVIF source-image upload support.
  • Default-on extended subject blend mask for smoother hairline, neck, shoulder, and upper-chest compositing.
  • Layered extended subject matte with soft falloff to reduce hard mask edges around hair and shoulders.
  • New Studio controls for extended subject masking and subject-mask preview overlay.
  • Fixed alpha-channel preview frames before face detection and swap-model inference.
  • Packaged runtime preflight and installer smoke tests are included under build/windows.

Known Requirements

  • ffmpeg/ffprobe must be installed separately for video workflows unless a future release explicitly bundles a reviewed ffmpeg build.
  • NVIDIA GPU acceleration requires compatible NVIDIA drivers and runtime libraries. CPU fallback should be tested before publishing.
  • OBS Virtual Camera workflows require OBS Studio installed separately.

Compliance Notes

Review these files before publishing:

  • COMPLIANCE.md
  • THIRD_PARTY_NOTICES.md
  • LICENSES/PYTHON_DEPENDENCIES.md
  • MODEL_DOWNLOAD_VERIFICATION.md
  • PROCESSING_VERIFICATION.md
  • RELEASE_CHECKLIST.md
  • RELEASE_REPORT.md

Known legal risks that must not be hidden from release notes:

  • The inswapper model family has historical non-commercial/research-use restrictions from InsightFace even where mirrors are labeled GPL-3.0.
  • GPEN upscaler model mirrors are marked non-commercial, academic, and educational use only.
  • pyvirtualcam metadata reports GPLv2; review binary distribution compatibility.
  • Dependency metadata can be incomplete and should be legally reviewed before public distribution.

Pre-Publish Checks

This release candidate is not publish-approved by release notes alone; publish
approval is recorded in RELEASE_VERIFICATION.md, MANUAL_RELEASE_GATES.md,
and the signed gate documents included with the upload.

Completed local evidence is included in the uploaded release documents:

  • Packaged runtime preflight.
  • Installer smoke test.
  • Model download/checksum verification.
  • CPU fallback processing.
  • CUDA processing on the local NVIDIA test machine.

Remaining publish blockers:

  • None when RELEASE_VERIFICATION.md says Ready to publish without remaining manual gates: YES.

Completed manual signoffs include:

  • Clean Windows VM install without admin rights.
  • OBS Virtual Camera workflow.
  • Authorized legal review for dependency, model-license, and redistribution obligations.
