Confidence Thresholds

+
+ Set the minimum confidence level (0.0 - 1.0) required to trigger filtering. + Higher values = more strict filtering (only very confident detections). +
+ +
+ + +
Current: 0.35 (moderate). Lower = more sensitive, Higher = less sensitive
+
+ +
+ + +
Revealing clothing and partial-skin scenes typically score 0.05–0.40. Recommended: 0.05 (strict) to 0.10 (moderate). Lower = more sensitive.
+
+ +
+ + +
⚠️ The violence classifier outputs ~0.50 for all action/war movie content. Values below 0.65 will flag virtually every scene in action films. Recommended: 0.65–0.75 to catch only explicitly violent content.
+
+ +
+ + +
Current: 0.30 (moderate). Lower = more sensitive, Higher = less sensitive
+
+ +
+ + +
Requires this minimum immodesty score to confirm a nudity detection. Eliminates false positives where the nudity detector fires on skin-toned backgrounds (e.g. war scenes). Set to 0.00 to disable and use nudity score alone.
+
+ +
+ + +
+ +
+ + +
Directory path where segment data is stored
+
+ +
+ + +
Primary scene-analyzer URL (e.g. http://localhost:3002).
+
+ +
+ + +
Optional extra hosts for load spreading/failover. Separate URLs with commas or semicolons.
+
+ +
+ + +
+ +

Path Mapping (Docker)

+
+ When Jellyfin and the AI services run in separate Docker containers, their media paths differ. + Set the root path Jellyfin uses and the corresponding root path the AI services use. +
+ +
+ + +
The media root path as seen by Jellyfin (e.g. /data/media/movies or D:\Media\Movies)
+
+ +
+ + +
The same media root path as seen by the AI service containers (e.g. /mnt/media)
+
+ +

Scene Detection Method

+
+ Choose how video scenes are detected for analysis. Different methods balance accuracy vs. speed. +
+ +
+ + +
+ + + + + + + +
+ + +
Higher values catch short/immediate content more reliably, but increase analysis time.
+
+ +

Analysis Queue Controls (Admin)

+
+ Pause/resume queued AI analysis jobs without stopping containers. This is useful when you want to temporarily free compute resources. +
+
+

Useful when AI jobs share compute with playback transcodes. Disable this if AI runs on a separate host and should keep processing during transcoding.
+
+ +
+ +
Prefer community-curated segments over AI-generated ones when available
+
+ +
+ +
Show on-screen notifications when content is filtered

All processing runs locally via Docker — no data is sent externally. + +### How does it work? + +A scheduled task analyzes your media library by sending video frames to local AI services. Detected segments are stored as JSON files. During playback, the plugin monitors position and seeks over flagged segments. + +--- + +## Compatibility + +### Does PureFin work with all Jellyfin clients? + +Only clients that support chapter/segment skip via the Jellyfin API. Web and most mobile clients support this. Direct DLNA playback does **not** support server-side skip actions. + +### Which Jellyfin versions are supported? + +Jellyfin **10.11.x**. The plugin targets `targetAbi 10.11.0.0` and is built against Jellyfin package version 10.11.8. + +### Does it work with Emby or Plex? + +No. PureFin uses Jellyfin-specific APIs and will only work with Jellyfin. + +--- + +## Features + +### Can I mute audio instead of skipping? + +The mute action is **not yet supported** via the Jellyfin plugin API. When the action is set to `mute`, the plugin falls back to `skip` and logs a warning. True mute support would require client-side cooperation. + +### Does per-user filtering work? + +Per-user profiles are **planned for a future release**. Currently, all users share the global plugin configuration. + +### Will PureFin work offline? + +Yes. All AI services run locally via Docker — no external network calls are made for analysis or filtering. + +### Can I filter profanity? + +Profanity filtering requires the audio pipeline (Whisper transcription), which is **not yet implemented**. The `EnableProfanity` toggle is present but currently has no effect. + +--- + +## Setup and Operations + +### Do I need a GPU? + +No. A GPU is optional but will speed up initial library analysis significantly. + +### How long does initial analysis take? + +Depends on library size and hardware: +- ~2–5 minutes per hour of video (GPU) +- ~5–15 minutes per hour of video (CPU) + +### Why are my AI services returning HTTP 503? + +Placeholder/random model generation has been removed. The services return 503 until real model files are placed at the paths defined in `ai-services/models/model-manifest.json`.

Run `docker compose ps` in `ai-services/` — all services should show `Up`: + ```bash + cd ai-services + docker compose ps + ``` + +2. Check readiness of each service: + ```bash + curl http://localhost:3001/ready # nsfw-detector + curl http://localhost:3002/ready # scene-analyzer + curl http://localhost:3003/ready # violence-detector + ``` + +3. **Expected response when ready:** + ```json + {"status": "ready", "models_loaded": true} + ``` + + Services may also return ready with lazy loading when models are currently unloaded to save memory: + ```json + {"status": "ready", "models_loaded": false, "lazy_load": true} + ``` + +4. **Expected response when degraded (models not loaded):** + ```json + {"status": "degraded", "models_loaded": false, "reason": "Model file not found at ..."} + ``` + +5. Check Docker logs for errors: + ```bash + docker compose logs --tail=50 + ``` + +--- + +## Services Degraded (Models Not Loaded) + +**Symptoms:** `/ready` returns `{"status": "degraded"}` and services return HTTP 503 for analysis requests. + +**Cause:** Placeholder/random model generation has been disabled. Real model files must be provided. + +**Steps:** + +1. Check `ai-services/models/model-manifest.json` to see which model files are expected and at which paths. + +2. Obtain real model files: + - NSFW model files (`models/nsfw/mobilenet_v2_140_224/*`) + - Violence profile model files (`models/violence/speed|balanced|quality/*`) or allow lazy download + - CLIP model weights — for content-classifier (legacy/optional) + +3. Place model files in the paths specified in the manifest. + +4. Restart services: + ```bash + docker compose restart + ``` + +5. Verify: `curl http://localhost:3001/ready` should now return `{"status": "ready", "models_loaded": true}`. + +--- + +## Analysis Not Running + +**Symptoms:** No segments are being created; playback filtering never triggers. + +**Steps:** + +1. Go to **Dashboard → Scheduled Tasks → Analyze Library for PureFin** and run it manually. + +2. Check the plugin log for errors from `AnalyzeLibraryTask`: + ```bash + grep -i "AnalyzeLibraryTask\|PureFin\|Jellyfin.Plugin.ContentFilter" /var/log/jellyfin/*.log + ``` + +3. Verify AI services are reachable (see section above). + +### Task exits immediately with "Video file not found" + +**Symptoms:** Scheduled task starts and completes in seconds; logs show: +`Scene analyzer endpoint ... returned error: NotFound - {"error":"Video file not found"}`. + +**Cause:** Jellyfin path mapping does not match the remote AI host's mounted media path, +or the movie is not present on the remote host. + +**Fix:** +1. In plugin settings, set: + - `JellyfinMediaPath` to Jellyfin's media root (example: `/data/media/movies`) + - `AiServiceMediaPath` to AI container media root (example: `/mnt/media`) +2. Verify the file exists inside scene-analyzer: + ```bash + docker exec scene-analyzer ls "/mnt/media//" + ``` +3. Re-run **Analyze Library for PureFin**. + +--- + +## Profanity detector unexpectedly uses CPU on NVIDIA + +**Symptoms:** Profanity logs show: +- `Whisper GPU transcription failed ... retrying on CPU` +- `FP16 is not supported on CPU` + +**Fix:** +1. Rebuild profanity service with the current NVIDIA Dockerfile (pinned torch/cu124 + numba/llvmlite): + ```bash + docker compose -f docker-compose.yml -f docker-compose.gpu.yml up -d --build profanity-detector + ``` +2. Confirm startup log includes: + - `Loading Whisper 'base' model on cuda` + - `Whisper model loaded successfully` + +--- + +## Queue Is Paused + +**Symptoms:** Analysis jobs remain pending and do not progress. + +**Steps:** + +1. Open **Dashboard → Plugins → PureFin**. +2. In **Analysis Queue Controls (Admin)**, check status. +3. Click **Resume Queue**. +4. Recheck status and confirm active/processed counters are moving. + +You can also query directly: +```bash +curl http://localhost:3002/queue/status +``` + +--- + +## Models Keep Unloading + +**Symptoms:** First analysis call after inactivity is slower. + +**Cause:** Idle model auto-unload is enabled by design to free resources. + +**Options:** + +1. Increase timeout in `ai-services/docker-compose.yml`: + - `MODEL_IDLE_UNLOAD_SECONDS=1800` (example) +2. Disable unload entirely: + - `MODEL_IDLE_UNLOAD_SECONDS=0` +3. Restart services after changes: + ```bash + docker compose up -d + ``` + +--- + +## Filtering Not Happening During Playback + +**Symptoms:** Analysis has completed but content is not being skipped during playback. + +**Steps:** + +1. Confirm that analysis has been run and segment files exist in the segment directory (default: `/segments/`). + +2. Check the configured sensitivity level — if set to `permissive`, only very high-confidence detections are triggered (threshold 0.85). + +3. Verify the relevant content categories are enabled in plugin settings (EnableNudity, EnableViolence, etc.). + +4. Check the plugin log for `PlaybackMonitor` entries during playback. + +--- + +## Getting Help + +1. Check the [FAQ](./faq.md) +2.
