It specifically targets "broken" formats like TS/AVI to fix timestamps before any other processing occurs. +- **Subfunctions**: + - `stripStar`: Utility to clean UI-selected default markers. +- **Default Settings**: + - `target_container`: `mkv` (**Authoritative** - all subsequent plugins inherit this) + - `fix_ts_timestamps`: `true` (Applies `-fflags +genpts+igndts -avoid_negative_ts make_zero -copyts`) + - `ts_audio_recovery`: `false` (Transcodes corrupt TS audio to AAC) + +### [02] Stream Cleanup +**Logic**: Evaluates every stream against the current container's capabilities (auto-detected from file). It removes image streams (cover art), corrupt audio (0 channels), and data streams that cause muxing errors. +- **Container**: Inherited from input file (set by Plugin 01) +- **Subfunctions**: + - `stripStar`: Utility to clean UI-selected default markers. +- **Default Settings**: + - `remove_image_streams`: `true` (Removes MJPEG/PNG/GIF) + - `force_conform`: `true` (Removes codecs like `mov_text` from MKV or `PGS` from MP4) + - `remove_corrupt_audio`: `true` (Removes 0-channel/unknown audio) + - `remove_data_streams`: `true` (Removes `bin_data`/`timed_id3`) + +### [03] Stream Ordering +**Logic**: Reorganizes the internal stream index. Ensures Video is first, followed by Audio, then Subtitles. Within Audio/Subtitles, it prioritizes a list of language codes. +- **Subfunctions**: + - `validateLanguageCodes`: Validates and sanitizes the CSV input. + - `isPriorityLanguage`: Checks if a stream matches the priority list. + - `partitionStreams`: Splits streams into priority and non-priority groups. +- **Default Settings**: + - `ensure_video_first`: `true` + - `reorder_audio`: `true` + - `reorder_subtitles`: `true` + - `priority_languages`: `eng,en,english,en-us,en-gb,en-ca,en-au` + - `set_default_flags`: `false` (Set disposition to 'default' for top priority tracks) + +### [04] Subtitle Conversion +**Logic**: **Container-aware** subtitle conversion. Converts text-based subtitles to the appropriate format for the current container (inherited from Plugin 01). +- **Container Behavior**: + - MKV → Converts to SRT (universal text format) + - MP4 → Converts to mov_text (native MP4 format) +- **Converts**: ASS/SSA, WebVTT, mov_text, SRT (cross-converts as needed) +- **Image subs** (PGS/VobSub): Copied as-is (cannot convert to text) +- **Default Settings**: + - `enable_conversion`: `true` + - `always_convert_webvtt`: `true` (WebVTT is problematic in most containers) + +### [05] Subtitle Extraction +**Logic**: Extracts embedded SRT-compatible subtitles to external `.srt` files. It includes robust logic to detect if it's already in a Tdarr cache cycle to prevent infinite "Extract -> Re-queue -> Extract" loops. +- **Subfunctions**: + - `sanitizeFilename`: Cleans language tags and titles for filesystem safety. + - `sanitizeForShell`: Prevents shell injection in extraction commands. + - `fileExistsValid`: Checks if an extracted file already exists and has data. +- **Default Settings**: + - `extract_subtitles`: `true` + - `remove_after_extract`: `false` + - `skip_commentary`: `true` + - `extract_languages`: `""` (Extracts all) + +### [06] CC Extraction +**Logic**: Uses the `CCExtractor` binary to pull EIA-608/708 captions. It uses a `.lock` file system to prevent multiple workers from trying to extract the same CC stream simultaneously. +- **Subfunctions**: + - `hasClosedCaptions`: Checks for specific CC codec tags. + - `sanitizeForShell`: Prevents shell injection. +- **Default Settings**: + - `extract_cc`: `false` + - `embed_extracted_cc`: `false` + +### [07] Audio Standardizer +**Logic**: Sophisticated audio engine. It handles codec conversion (AAC/Opus), bitrate calculation (automatic per-channel limits), and multi-channel downmixing (7.1 -> 5.1 -> 2.0). +- **Subfunctions**: + - `calculateBitrate`: Smart logic to ensure quality while keeping files small. + - `applyQualityPreset`: Provides `high_quality`, `balanced`, and `small_size` presets. + - `buildDownmixArgs`: Generates specific FFmpeg maps for new downmixed tracks. + - `isOpusIncompatibleLayout`: Handles Opus layout corner cases. +- **Default Settings**: + - `codec`: `opus` + - `skip_if_compatible`: `true` + - `bitrate_per_channel`: `auto` (Min 64kbps/ch) + - `channel_mode`: `preserve` + - `create_downmix`: `true` (Creates stereo if missing) + - `quality_preset`: `custom` + +### [08] AV1 Converter (SVT-AV1) +**Logic**: Optimized for SVT-AV1 v3.0+.

Stack Architecture Overview + +The plugin stack operates in a **sequential re-queue model**. Each plugin that modifies the file triggers a `reQueueAfter: true`, causing Tdarr to process the output and restart the stack from the beginning with the new file. + +**Current Order:** +1. `misc_fixes` (Container/Remux/Clean) +2. `stream_organizer` (Subtitle Extraction/Reorder) +3. `combined_audio_standardizer` (Audio Transcode/Downmix) +4. `av1_svt_converter` (Video Transcode) + +### 🚨 Architectural Risks & Findings +* **High I/O Overhead:** This stack can potentially trigger **4 separate transcode/remux cycles** per file. + * Pass 1: Remux to MKV (misc_fixes) + * Pass 2: Reorder/Extract Subtitles (stream_organizer) + * Pass 3: Audio Transcode (audio_standardizer) + * Pass 4: Video Transcode (av1_converter) + * *Recommendation:* Consider combining logic where possible, or accepting high I/O for modularity. +* **Race Conditions:** `stream_organizer` handles CC extraction via mostly atomic locks, but file existence checks in Tdarr's distributed environment are always tricky. The current `reQueueAfter` logic relies heavily on "state convergence" (eventually the file meets criteria). + +--- + +## 2. Individual Plugin Analysis + +### A. Tdarr_Plugin_misc_fixes.js (v2.8) + +**Overview:** Handles container standardization, stream cleaning, and TS fixes. + +**Strengths:** +* **Correct Logic Flow:** Checks for "work already done" (e.g., `currentContainer !== targetContainer`, `firstStreamIsVideo`) to prevent infinite loops. +* **Robust Skip Logic:** Correctly identifies unfixable ISO/TS files early. + +**Issues & Improvements:** +1. **Complexity/Refactoring:** The `plugin` function is becoming monolithic. + * *Suggestion:* Extract `analyzeStreams` and `buildFFmpegCommand` into helper functions. +2. **Hardcoded Lists:** `brokenTypes`, `image codecs` are defined inside the function. + * *Fix:* Move `const` definitions (like `BROKEN_TYPES`, `IMAGE_CODECS`) to top-level scope for readability and memory efficiency. +3. **Variable Shadowing:** `inputs` is reassigned (`inputs = lib.loadDefaultValues...`). Ideally, use `const settings = ...` to avoid mutating arguments. + +### B. Tdarr_Plugin_stream_organizer.js (v4.8) + +**Overview:** Manages subtitles, language ordering, and extraction. + +**Strengths:** +* **Sanitization:** Strong input/filename sanitization (`sanitizeFilename`, `sanitizeForShell`). +* **Loop Protection:** Excellent use of `MAX_EXTRACTION_ATTEMPTS` and `extractionAttempts` map (though memory-only). +* **Robustness:** `fileExistsRobust` wrapper helps with filesystem flakes. + +**Issues & Improvements:** +1. **Massive Function Size:** The `plugin` function is ~500 lines. It violates Single Responsibility Principle. + * *Critical Refactor:* Move stream analysis, extraction logic, and command building into separate functions: `getReorderedStreams()`, `processSubtitles()`, `buildFFmpegArgs()`. +2. **Redundant Logic:** `isEnglishStream` is used in partitioning and mapping loops separately. +3. **CC Extraction Lock:** The lock file mechanism (`.lock`) is decent but relies on `process.pid`. If a node crashes hard, the lock remains. + * *Recommendation:* Add a "stale lock" check (e.g., if lock file > 1 hour old, ignore/delete it). +4. **Efficiency:** The `partitionStreams` logic iterates arrays multiple times. + +### C. Tdarr_Plugin_combined_audio_standardizer.js (v1.13) + +**Overview:** Complex audio mapping, downmixing, and transcoding. + +**Strengths:** +* **Modular Helpers:** `buildCodecArgs`, `buildDownmixArgs`, `calculateBitrate` are well-separated. Good code structure. +* **Explicit Mapping:** Correctly handles attachments via `streamMap` construction (prevents the "muxing overhead 400%" issues). + +**Issues & Improvements:** +1. **Complex Conditionals:** The `needsTranscoding` logic is a bit nested. +2. **Downmix Logic Risk:** `buildDownmixArgs` assumes the source stream is compatible with the `downmix` filter. Usually safe, but edge cases exist. +3. **Attachment Handling:** It maps `0:t` copies, but `misc_fixes` might have stripped images. + * *Check:* If `misc_fixes` runs first, it removes images. `audio_standardizer` won't see them in `file.ffProbeData` (sourced from Tdarr DB). + * *Risk:* If Tdarr DB is stale (scan didn't happen after misc_fixes?), `combined_audio` might try to map non-existent streams. + * *Mitigation:* `reQueueAfter` usually forces a rescan, so this should be safe. + +### D. Tdarr_Plugin_av1_svt_converter.js (v2.22) + +**Overview:** AV1 video encoding. + +**Strengths:** +* **Modern AV1 Handling:** Good use of SVT-AV1 parameters (SCD, TF, etc.). +* **Resolution Awareness:** Smart CRF adjustment logic based on resolution. +* **Input Handling:** Explicit checks for HDR/10-bit. + +**Issues & Improvements:** +1. **Argument Injection Risk (Low):** `svtParams` is constructed from inputs. While inputs are sanitized (stripped stars), strict type validation would be better before injection. +2. **Parsing Logic:** `resolutionMap` is hardcoded. +3. **Bitrate Strategy:** The `target_bitrate_strategy` logic is complex and relies on accurate source bitrate detection, which isn't always available in `ffProbeData`. + * *Suggestion:* Add fallback if `bit_rate` is missing/NaN (currently defaults to safe uncapped, which is acceptable). + +--- + +## 3. General Best Practice Violations + +1. **Shared Helpers Duplication:** + * `stripStar` is defined in EVERY plugin. + * `sanitizeForShell` is in multiple plugins. + * *Fix:* You have a `lib/sanitization.js` (referenced in chat history), but plugins currently duplicate this code. They should `require` the shared library if Tdarr environment permits, OR (if Tdarr requires self-contained plugins) this duplication is a necessary evil. + * *Observation:* Plugins currently require `../methods/lib` (Tdarr internal). Custom libs in `/Local` might not be reliably accessible across nodes unless explicitly distributed. + +2. **Magic Numbers:** + * `MAX_EXTRACTION_ATTEMPTS = 3` + * `MIN_SUBTITLE_FILE_SIZE = 100` + * Defined as constants in some files, literals in others. Standardize. + +3. **Error Handling Patterns:** + * Most plugins use `response.processFile = false` + `infoLog` on error. This is good Tdarr practice (don't crash the node). + +--- + +## 4. Recommendations & Refactoring Plan + +### Priority 1: Safety & Stability (Immediate) +* **Stale Lock Cleanup:** Implement stale lock check in `stream_organizer` (CC extraction). +* **Argument Validation:** Strengthen input validation in `av1_svt_converter` to ensure `svt-params` injection is perfectly safe. + +### Priority 2: Code Quality (Short-term) +* **De-duplication:** If Tdarr allows, strictly enforce using a shared `utils.js` for `stripStar`, `sanitizeFilename`, etc. +* **Modularization:** Refactor `stream_organizer.js` to break up the 500-line `plugin` function. + +### Priority 3: Architecture (Long-term) +* **Combine Passes:** Investigate merging `misc_fixes` and `stream_organizer` logic? + * *Counter-argument:* Keeping them separate is better for maintenance. + * *Alternative:* Use Tdarr's "Flows" (if upgrading to Tdarr V2 flows) or accept the I/O cost for robustness. + +## 5. Conclusion +The plugins are currently **FUNCTIONAL and SAFE** (after recent fixes). The code quality is generally high but suffers from "script creep" where functions have grown too large. Logic for infinite loop prevention is verified in place. + +**No immediate code changes required for safety**, but refactoring `stream_organizer` is highly recommended for maintainability. diff --git a/agent_notes/archive/Tdarr_Plugin_misc_fixes.js b/agent_notes/archive/Tdarr_Plugin_misc_fixes.js new file mode 100644 index 0000000..a61e61a --- /dev/null +++ b/agent_notes/archive/Tdarr_Plugin_misc_fixes.js @@ -0,0 +1,350 @@ +/* eslint-disable no-plusplus */ +const details = () => ({ + id: 'Tdarr_Plugin_misc_fixes', + Stage: 'Pre-processing', + Name: 'Misc Fixes', + Type: 'Video', + Operation: 'Transcode', + Description: ` + A consolidated 'Megamix' of fixes for common video file issues. + Combines functionality from Migz Remux, Migz Image Removal, Lmg1 Reorder, and custom timestamp fixes. + + Features: + - Fixes timestamps for TS/AVI/MPG files + - Optional TS audio recovery: extract + transcode audio to AAC for compatibility + - Remuxes to target container (MKV/MP4) + - Conforms streams to container (drops incompatible subtitles) + - Removes unwanted image streams (MJPEG/PNG/GIF) + - Ensures Video stream is ordered first + + Should be placed FIRST in your plugin stack. + `, + Version: '2.8', + Tags: 'action,ffmpeg,ts,remux,fix,megamix', + Inputs: [ + { + name: 'target_container', + type: 'string', + defaultValue: 'mkv', + inputUI: { + type: 'dropdown', + options: ['mkv', 'mp4'], + }, + tooltip: 'Target container format', + }, + { + name: 'force_conform', + type: 'string', + defaultValue: 'true*', + inputUI: { + type: 'dropdown', + options: ['true*', 'false'], + }, + tooltip: 'Drop streams incompatible with the target container (e.g. mov_text in MKV)', + }, + { + name: 'remove_image_streams', + type: 'string', + defaultValue: 'true*', + inputUI: { + type: 'dropdown', + options: ['true*', 'false'], + }, + tooltip: 'Remove MJPEG, PNG, and GIF video streams (often cover art or spam)', + }, + { + name: 'ensure_video_first', + type: 'string', + defaultValue: 'true*', + inputUI: { + type: 'dropdown', + options: ['true*', 'false'], + }, + tooltip: 'Reorder streams so Video is first, then Audio, then Subtitles', + }, + { + name: 'fix_ts_timestamps', + type: 'string', + defaultValue: 'true*', + inputUI: { + type: 'dropdown', + options: ['true*', 'false'], + }, + tooltip: 'Apply special timestamp fixes for TS/AVI/MPG files (-fflags +genpts)', + }, + { + name: 'ts_audio_recovery', + type: 'string', + defaultValue: 'false', + inputUI: { + type: 'dropdown', + options: ['false', 'true'], + }, + tooltip: 'TS files only: Extract and transcode audio to AAC for compatibility.
