Deep Live Cam Studio 2.2.1 Windows Release

This maintenance release modernizes the Windows dependency set, hardens the
release process, and safely refactors the UI/frame pipeline while preserving
the CUDA and DirectML workflows introduced in 2.2.0.

Downloads

  • NVIDIA/CUDA installer: DeepLiveCamStudio-2.2.1-x64-setup.exe
  • Installer SHA-256: D643924BFA22BF2B1BB309BE0DD7436B8A7DB8854003C9437950FBB2133752AF
  • AMD/Intel DirectML portable ZIP: DeepLiveCamStudio-2.2.1-DirectML-x64-portable.zip
  • DirectML portable SHA-256: 5DD825C8801B3F1C3E43C243D13967E5600C135C3076F7A3E423C648B347D5FD

  • Source ref: 1eebeb4cc0ec9d1e978182c19778d6f74538ba29

Use the CUDA installer for NVIDIA GPUs. Use the DirectML ZIP for AMD or Intel
DirectX 12 GPUs: extract it into a new folder and run
DeepLiveCamStudio.exe. Do not copy one runtime over another.

What Changed

Changed

  • Refreshed the reviewed Windows dependency set and regenerated reproducible
    CUDA and DirectML locks plus licence snapshots.
  • Refactored high-complexity UI and frame-pipeline orchestration behind
    characterization tests while preserving user-visible behavior.
  • Modernized the repository README, documentation, issue forms, support and
    security policies, dependency policy, and public project presentation.

Fixed

  • Removed stale release triggers, obsolete duplicate tooling, unused imports,
    and retired scaffolding without changing supported workflows.
  • Kept strict provider checks so CPU fallback cannot be mistaken for a
    successful CUDA or DirectML result.

An independent physical tester validated the release candidate on Windows 11
with a Radeon RX 9060 XT: the DirectML badge was active and Preview,
short-video Render, and OBS Live Output all passed with no blocking regression.
The packaged release runtimes are separately checked for their expected GPU
providers; CUDA rendering and Live Output were also verified locally on an
NVIDIA RTX 4070.

Source and license

Deep-Live-Cam is licensed under AGPL-3.0. Complete corresponding source for the
exact binary release is attached and identified by the source ref above.

The source archive is produced with:

powershell -ExecutionPolicy Bypass -File build\windows\package_source.ps1 -AppVersion 2.2.1 -GitRef 1eebeb4cc0ec9d1e978182c19778d6f74538ba29

This release preserves attribution to the original project:

Models are not bundled

The installer intentionally does not include model/checkpoint files. The
DirectML portable ZIP also excludes them because model licenses and
redistribution rights are separate from the application license.

After launching, select Set Up Models, or run:

DeepLiveCamStudioCLI.exe --download-models

Downloaded models are stored under:

%LOCALAPPDATA%\DeepLiveCamStudio\models

Requirements and known limitations

  • ffmpeg and ffprobe must be installed separately for video workflows.
  • OBS Studio must be installed separately for OBS Virtual Camera workflows.
  • The public files are unsigned and may trigger Microsoft Defender
    SmartScreen.
  • Face-swap and enhancer model families retain their documented
    non-commercial or research-use restrictions; no model weights are
    redistributed here.

Release evidence

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:

  • Full automated test suite.
  • Packaged CUDA and DirectML runtime/provider checks.
  • Installer smoke install/uninstall checks.
  • Model download/checksum and forbidden-model scans.
  • CUDA and DirectML file-render checks.
  • Radeon RX 9060 XT DirectML and NVIDIA RTX 4070 CUDA Live Output checks.

Remaining publish blockers:

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

Completed manual signoffs include:

  • Clean Windows install without admin rights.
  • OBS Virtual Camera and DirectML Live Output workflows.
  • Authorized legal review for dependency, model-license, and redistribution obligations.
