v1.6.1.16 — Three singletons, not one latest

Released April 2026. Issue #64 fix: LibraryUpscaleScanTask failing with Cannot start process because a file name has not been provided.

• Root cause: three service singletons (VideoAnalyzer, VideoFrameProcessor, ProcessingMethodExecutor) each captured MediaEncoder.EncoderPath/ProbePath as readonly strings at construction. When Jellyfin constructed the plugin before MediaEncoder finished resolving paths, those strings were empty — forever.
• Fix: made the cached paths mutable, added UpdateFFmpegPath() / UpdateFFprobePath() entry points, and introduced EnsureFFmpegReady() in VideoProcessor that re-queries MediaEncoder and propagates to every sub-service on every job entry.
• Verification: Pre-fix: nightly scan failed at 0/70 files. Post-fix (live-tested on Jellyfin 10.11.8): scan reached 31% with per-file Video analysis: 1280x720 @ 30.0fps log lines and FFmpeg ready: ffmpeg=/usr/lib/jellyfin-ffmpeg/ffmpeg.

v1.6.1.14 — Admin gates for jobs endpoint

• Security fix: /Upscaler/jobs no longer returns absolute file paths to non-admin authenticated users. Gated with RequiresElevation.
• Improved Test Connection diagnostics — now reports whether the failure was network-level, auth-level, or token-mismatch.

v1.6.1.12 — RIFE v4.7/v4.8/v4.9

• New RIFE frame-interpolation catalog: v4.9 (quality), v4.8 (balanced), v4.7 (fast).
• Old references to rife-v4.6 and rife-v4.6-lite in saved configs are auto-mapped via MODEL_ALIASES; no user action needed.
• Scene cut detection toggle on the Motion tab — avoids ghosting across hard cuts.

v1.6.1.10 — HAT family

• Added hat-s-x4, hat-m-x4, hat-l-x4 to the catalog for live-action at higher quality than Real-ESRGAN.
• Nomos8k-trained HAT variant (nomos8k-hat-x4) as [self-host required].

v1.6.1.8 — Face restoration pipeline

• GFPGAN v1.4 and CodeFormer added as first-class models.
• Full end-to-end pipeline /face-restore/pipeline — detects faces, restores them, upscales the surrounding frame, feathered paste-back.
• Toggle on the player quick-menu (Face Restore tab) for opt-in per-stream use.

v1.6.1.5 — Filter presets + live preview

• Six filter sliders (gamma, sharpness, temperature, vignette, grain, denoise) applied live via <video>.style.filter.
• Filter preview endpoint /Upscaler/filter-preview/frame/{itemId} — extracts a real frame from your library and renders before/after PNGs for the selected preset.
• Seven shipped presets: Cinema, Anime, Retro, Vivid, HDR-SDR, Soft, Documentary.

v1.6.1.4 — Service auth rework

• All service endpoints behind a single X-Api-Token. Previously, /logs-stream was unauthenticated when the token was unset.
• Dashboard shows api_token_configured and auth_enabled prominently.
• Console tab in the plugin UI streams service logs via SSE, token-gated.

v1.6.1.0 — Split into plugin + service

The architectural rewrite that the current generation is based on.

• Plugin-side: .NET 9, Jellyfin 10.11.x-targeted, HTTP-only contract with the service.
• Service-side: FastAPI + ONNX Runtime in its own Docker container. CUDA / OpenVINO / ROCm / CPU images.
• Twelve output codec presets with tuned ffmpeg parameters.
• Three scheduled tasks: library upscale, image upscale, cache cleanup.
• This is the baseline that all 1.6.1.x bugfix releases build on.

Older releases

Pre-1.6.x releases bundled inference inside the plugin process. They're archived on the GitHub Releases page but are no longer maintained. Upgrade to the current 1.6.1.x line.
