|
||||
## Key Code Changes
|
||||
|
||||
### Stream Organizer - Before
|
||||
```javascript
|
||||
// Old problematic code
|
||||
while ((extractedFiles.has(subsFile) || fs.existsSync(subsFile)) && counter < maxAttempts) {
|
||||
// Complex logic with caching issues
|
||||
subsFile = `${baseName}.${safeLang}.${counter}.srt`;
|
||||
counter++;
|
||||
}
|
||||
```
|
||||
|
||||
### Stream Organizer - After
|
||||
```javascript
|
||||
// New reliable code
|
||||
while (extractedFiles.has(subsFile) && counter < MAX_FILENAME_ATTEMPTS) {
|
||||
subsFile = `${baseName}.${safeLang}.${counter}.srt`;
|
||||
counter++;
|
||||
}
|
||||
|
||||
if (needsSubtitleExtraction(subsFile, baseFile, fs)) {
|
||||
// Extract (uses fs.statSync internally)
|
||||
} else {
|
||||
// Skip - file exists and is valid
|
||||
}
|
||||
```
|
||||
|
||||
### Error Handling - Before
|
||||
```javascript
|
||||
const plugin = (file, ...) => {
|
||||
inputs = lib.loadDefaultValues(inputs, details);
|
||||
// No error handling
|
||||
return response;
|
||||
};
|
||||
```
|
||||
|
||||
### Error Handling - After
|
||||
```javascript
|
||||
const plugin = (file, ...) => {
|
||||
const response = { /* initialize */ };
|
||||
|
||||
try {
|
||||
inputs = lib.loadDefaultValues(inputs, details);
|
||||
// Plugin logic
|
||||
return response;
|
||||
} catch (error) {
|
||||
response.processFile = false;
|
||||
response.infoLog = `💥 Plugin error: ${error.message}\n`;
|
||||
// Stack trace and context
|
||||
return response;
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||

# SVT-AV1 Plugin Bitrate Feature Analysis
|
||||
|
||||
## Current State
|
||||
|
||||
### Existing Bitrate Control
|
||||
|
||||
The plugin currently implements bitrate control via the `maxrate_cap` dropdown input:
|
||||
|
||||
- **Type**: Dropdown with 11 preset values
|
||||
- **Options**: `0` (unlimited), `2000`, `3000`, `4000`, `5000`, `6000`, `8000`, `10000`, `12000`, `15000`, `20000` kbps
|
||||
- **Default**: `0*` (unlimited)
|
||||
- **Implementation**: Lines 531-540 in the plugin
|
||||
- **Behavior**: When set to non-zero, applies `-maxrate` and `-bufsize` (2x maxrate) to FFmpeg command
|
||||
|
||||
### Current Logic Flow
|
||||
|
||||
```mermaid
|
||||
graph TD
|
||||
A[Start] --> B{maxrate_cap != 0?}
|
||||
B -->|Yes| C[Apply maxrate + bufsize<br/>Buffer = 2.0x maxrate]
|
||||
B -->|No| D[Uncapped CRF<br/>No bitrate limit]
|
||||
C --> E[Build FFmpeg Command]
|
||||
D --> E
|
||||
```
|
||||
|
||||
## Requirements from Agent Notes
|
||||
|
||||
From [implementation_plan.md](file:///home/user/Public/Projects/tdarr_plugs/Local/agent_notes/implementation_plan.md):
|
||||
|
||||
1. **Custom Maxrate**: Allow users to manually type a specific kbps value (not limited to dropdown presets)
|
||||
2. **Source-Relative Bitrate**: Allow setting bitrate cap relative to source file bitrate
|
||||
- Options: `match_source`, `75%_source`, `50%_source`, `33%_source`, `25%_source`
|
||||
3. **Logic Precedence**:
|
||||
- If strategy ≠ static → Calculate from source
|
||||
- Else if custom_maxrate > 0 → Use custom value
|
||||
- Else → Use maxrate_cap dropdown
|
||||
|
||||
## Design Decisions
|
||||
|
||||
### Input Design
|
||||
|
||||
**1. Custom Maxrate Input**
|
||||
- **Type**: Text input (string)
|
||||
- **Default**: Empty string `''`
|
||||
- **Validation**: Parse as integer, check > 0, handle NaN gracefully
|
||||
- **Position**: After `maxrate_cap` dropdown
|
||||
|
||||
**2. Target Bitrate Strategy Dropdown**
|
||||
- **Type**: Dropdown
|
||||
- **Options**: 6 choices
|
||||
- `static*` - Use custom_maxrate or maxrate_cap (default)
|
||||
- `match_source` - Match source bitrate (100%)
|
||||
- `75%_source` - 75% of source
|
||||
- `50%_source` - 50% of source
|
||||
- `33%_source` - 33% of source
|
||||
- `25%_source` - 25% of source
|
||||
- **Position**: After `custom_maxrate` input
|
||||
|
||||
### Bitrate Detection Strategy
|
||||
|
||||
```mermaid
|
||||
graph TD
|
||||
A[Start] --> B[Check videoStream.bit_rate]
|
||||
B -->|Available| C[Use video stream bitrate]
|
||||
B -->|Missing| D[Check format.bit_rate]
|
||||
D -->|Available| E[Use overall file bitrate]
|
||||
D -->|Missing| F[sourceBitrateKbps = null<br/>Log warning]
|
||||
C --> G[Convert bps to kbps]
|
||||
E --> G
|
||||
G --> H[sourceBitrateKbps ready]
|
||||
F --> I[Fall back to static mode]
|
||||
```
|
||||
|
||||
**Key Details**:
|
||||
- Primary source: `file.ffProbeData.streams[videoStreamIndex].bit_rate` (bps)
|
||||
- Fallback: `file.ffProbeData.format.bit_rate` (bps)
|
||||
- Conversion: Divide by 1000 to get kbps
|
||||
- Graceful failure: If neither available, log warning and use static mode
|
||||
|
||||
### Logic Precedence Implementation
|
||||
|
||||
```javascript
|
||||
// Priority 1: target_bitrate_strategy (highest)
|
||||
if (strategy !== 'static' && sourceBitrateKbps) {
|
||||
calculatedMaxrate = Math.round(sourceBitrateKbps * multiplier);
|
||||
}
|
||||
|
||||
// Priority 2: custom_maxrate (middle)
|
||||
if (!calculatedMaxrate && custom_maxrate !== '' && parseInt(custom_maxrate) > 0) {
|
||||
calculatedMaxrate = parseInt(custom_maxrate);
|
||||
}
|
||||
|
||||
// Priority 3: maxrate_cap dropdown (lowest, existing)
|
||||
if (!calculatedMaxrate && maxrate_cap !== '0') {
|
||||
calculatedMaxrate = parseInt(maxrate_cap);
|
||||
}
|
||||
|
||||
// Priority 4: No limit (default)
|
||||
if (!calculatedMaxrate) {
|
||||
// Uncapped CRF mode (existing behavior)
|
||||
}
|
||||
```
|
||||
|
||||
### Info Logging Strategy
|
||||
|
||||
Add clear logs to help users understand which bitrate method was used:
|
||||
|
||||
- **Strategy mode**: `"Using target bitrate strategy '50%_source': Source bitrate 10000k → Maxrate 5000k"`
|
||||
- **Custom mode**: `"Using custom maxrate: 7500k"`
|
||||
- **Dropdown mode**: `"Using maxrate cap from dropdown: 5000k"`
|
||||
- **Fallback warning**: `"Warning: target_bitrate_strategy selected but source bitrate unavailable. Falling back to static mode."`
|
||||
|
||||
## Edge Cases to Handle
|
||||
|
||||
1. **Invalid custom_maxrate input**
|
||||
- Non-numeric strings → Ignore, fall through to dropdown
|
||||
- Negative numbers → Ignore, fall through to dropdown
|
||||
- Zero → Treat as empty, fall through to dropdown
|
||||
|
||||
2. **Missing source bitrate with strategy selected**
|
||||
- Log warning message
|
||||
- Fall back to custom_maxrate or maxrate_cap
|
||||
- Don't error/crash the plugin
|
||||
|
||||
3. **All inputs empty/zero**
|
||||
- Default to uncapped CRF mode (existing behavior)
|
||||
- No maxrate applied
|
||||
|
||||
4. **Conflicting inputs**
|
||||
- User sets both strategy and custom_maxrate
|
||||
- Strategy takes precedence (as designed)
|
||||
- Log which one was used
|
||||
|
||||
## Compatibility Considerations
|
||||
|
||||
- **Backward compatible**: Existing configurations continue to work
|
||||
- **Default behavior**: `target_bitrate_strategy = 'static'` and `custom_maxrate = ''` → Original behavior
|
||||
- **No breaking changes**: All new inputs have safe defaults
|
||||
- **FFmpeg compatibility**: Uses existing `-maxrate` and `-bufsize` flags (no new FFmpeg requirements)

# Audio Standardizer Plugin - Code Review
|
||||
|
||||
## 🔴 Critical Issues
|
||||
|
||||
**1. Quality preset bitrate display is incorrect (Line 623-624)**
|
||||
```javascript
|
||||
response.infoLog += ` Stereo downmix bitrate: ${stereoBitrate}kbps (calculated: 2 × ${inputs.bitrate_per_channel})\\n`;
|
||||
```
|
||||
- Displays `inputs.bitrate_per_channel` which could be 'auto' or 'original' (not a number)
|
||||
- Should show actual numerical value used
|
||||
|
||||
**2. Missing validation for preset quality (Line 261)**
|
||||
```javascript
|
||||
const preset = QUALITY_PRESETS[inputs.quality_preset];
|
||||
if (!preset) {
|
||||
return inputs; // Silent failure
|
||||
}
|
||||
```
|
||||
- Should log warning if preset not found
|
||||
|
||||
## 🟡 Medium Issues
|
||||
|
||||
**3. Inconsistent emoji usage in logs**
|
||||
- Mix of ☑️ (check) for errors and successes
|
||||
- Use ❌ for errors, ✅ for success, ℹ️ for info
|
||||
|
||||
**4. Unused `small_size` preset has incorrect Opus bitrate**
|
||||
```javascript
|
||||
small_size: {
|
||||
opus_bitrate_per_channel: '48', // 48kbps is very low for Opus
|
||||
```
|
||||
- Opus minimum bitrate should be 64kbps for acceptable quality
|
||||
- 48kbps may produce poor audio
|
||||
|
||||
**5. Duplicate bitrate calculation in downmix (Lines 319, 590)**
|
||||
```javascript
|
||||
const stereoBitrate = calculateBitrate(inputs, 2, null); // Line 319
|
||||
...
|
||||
const stereoBitrate = calculateBitrate(inputs, 2, null); // Line 590
|
||||
```
|
||||
- Calculate once and reuse
|
||||
|
||||
**6. No minimum bitrate threshold**
|
||||
- Unlike video plugin, no floor for calculated bitrates
|
||||
- Could result in unusable <16kbps audio with certain inputs
|
||||
|
||||
**7. Opus compression level hardcoded (Line 299)**
|
||||
```javascript
|
||||
-compression_level 10
|
||||
```
|
||||
- Could be exposed as input option (0-10 range)
|
||||
- Higher = slower but better quality
|
||||
|
||||
## 🟢 Potential Improvements
|
||||
|
||||
**8. Add audio sample rate handling**
|
||||
- No validation or handling of unusual sample rates
|
||||
- Could add resampling option (48kHz standard for streaming)
|
||||
|
||||
**9. Add language/title metadata preservation**
|
||||
- Currently only adds "2.0 Downmix" title
|
||||
- Should preserve original audio titles and language tags
|
||||
|
||||
**10. Add normalization option**
|
||||
- EBU R128 loudness normalization would be useful
|
||||
- Common for streaming content
|
||||
|
||||
**11. Version bump needed**
|
||||
- After fixes, increment from 1.04
|
||||
|
||||
**12. Add channel layout validation for Opus incompatible layouts**
|
||||
- Currently only logs layout compatibility
|
||||
- Could warn user before processing
|
||||
|
||||
**13. Improve auto bitrate calculation**
|
||||
```javascript
|
||||
const targetBitrate = 64 * channels; // Line 236
|
||||
```
|
||||
- 64kbps may be overkill for mono/stereo
|
||||
- Could use: `Math.max(32, Math.min(96, 48 * Math.log2(channels + 1)))`
|
||||
|
||||
**14. Add AAC profile selection**
|
||||
- Currently uses default AAC-LC
|
||||
- Could expose AAC-LC vs AAC-HE vs AAC-HEv2
|
||||
|
||||
**15. Add 5.1 → 5.1 downmix from 7.1**
|
||||
- Currently only creates 2ch from 6ch/8ch
|
||||
- Missing 8ch → 6ch downmix option
|
||||
|
||||
## 📋 Redundancies
|
||||
|
||||
**16. Duplicate COMPATIBLE_CODECS array (Line 171)**
|
||||
- Already defined as constants
|
||||
- Use `CODECS.AAC, CODECS.OPUS, CODECS.LIBOPUS` directly everywhere
|
||||
|
||||
**17. Redundant opus codec check (Lines 530-537)**
|
||||
```javascript
|
||||
if (!streamNeedsTranscode) {
|
||||
streamNeedsTranscode = true; // Redundant assignment
|
||||
}
|
||||
```
|
||||
- Can simplify logic
|
||||
|
||||
**18. Empty lines (415-416)**
|
||||
- Two blank lines in validation function
|
||||
|
||||
## 🔧 Optimizations
|
||||
|
||||
**19. Use Set for OPUS_INCOMPATIBLE_LAYOUTS**
|
||||
```javascript
|
||||
const OPUS_INCOMPATIBLE_LAYOUTS = new Set([...]);
|
||||
```
|
||||
- Faster lookups with `.has()` vs `.includes()`
|
||||
|
||||
**20. Cache regex for star removal**
|
||||
- Currently creates new slice operation each iteration
|
||||
- Minor but could optimize
|
||||
|
||||
**21. Reduce try-catch blocks**
|
||||
- Three separate try-catch blocks (Lines 474, 525, 585)
|
||||
- Could consolidate error handling
|
||||
|
||||
## 🎯 Priority Fixes Table

# AV1 Plugin Analysis
|
||||
|
||||
## Exposed Feature & Defaults
|
||||
|
||||
| Feature | Input Name | Default Value | Description |
|
||||
| :--- | :--- | :--- | :--- |
|
||||
| **CRF** | `crf` | `29` | Constant Rate Factor. Main quality knob. |
|
||||

||||
| **Bitrate Cap** | `maxrate_cap` | `0` (Unlimited) | Max bitrate in kbps. |
|
||||
| **Resolution** | `max_resolution` | `none` | Downscaling target. |
|
||||
| **Auto-CRF** | `resolution_crf_adjust`| `enabled` | Adjusts CRF based on res (+2 for 4K, -2 for 720p). |
|

## Internal / Hardcoded Settings
|
||||
These settings are not exposed to the user in the Tdarr UI and are hardcoded in the plugin logic:
|
||||
|
||||
* **qmin**: `10` (Minimum Quantizer, prevents extreme quality boost that wastes space)
|
||||
* **qmax**: `50` (Maximum Quantizer, prevents extreme quality loss)
|
||||
* **Buffer Size**: Calculated as `2.0 * maxrate` (only if maxrate is set).
|
||||
* **Pixel Format**:
|
||||
* For 8-bit: Implicit (standard `yuv420p` usually).
|
||||
* For 10-bit: Explicitly set to `yuv420p10le`.
|
||||
* **Audio/Subs**: `-c:a copy -c:s copy` (Passthrough).
|
||||
* **Data Streams**: `-dn` (Discarded).

# English First Plugin - Code Review
|
||||
|
||||
## 🔴 Critical Issues
|
||||
|
||||
**1. Missing error handling for shell command (Line 421)**
|
||||
```javascript
|
||||
response.preset = `${ccCmd} && ${command}`;
|
||||
```
|
||||
- No handling if ccextractor fails - entire command chain fails
|
||||
- Should use `;` or `||` for better error handling
|
||||
|
||||
**2. Input property inconsistency (Lines 17-86)**
|
||||
- Uses `label` property which is non-standard
|
||||
- Should use `name` for consistency with other plugins
|
||||
|
||||
**3. `needsPerStreamCodec` variable declared but never used (Line 346)**
|
||||
```javascript
|
||||
let needsPerStreamCodec = false; // eslint-disable-line @typescript-eslint/no-unused-vars
|
||||
```
|
||||
- Dead code with eslint disable comment
|
||||
|
||||
## 🟡 Medium Issues
|
||||
|
||||
**4. No emoji standardization**
|
||||
- Uses plain text messages throughout
|
||||
- Should use ❌ ✅ ℹ️ ⚠️ like other plugins
|
||||
|
||||
**5. Inconsistent "Yes"/"No" vs boolean (Lines 18-86)**
|
||||
- All inputs use string "Yes"/"No" instead of "true*"/"false"
|
||||
- Not consistent with other plugins
|
||||
|
||||
**6. Missing validation for inputs**
|
||||
- No validateInputs function
|
||||
- Could have invalid dropdown values pass through
|
||||
|
||||
**7. Long complex conditional (Lines 313-314)**
|
||||
```javascript
|
||||
if (!needsReorder && !needsConversion && extractCount === 0 && !ccActuallyExtracted &&
|
||||
!(ccExtractedFile && inputs.embedExtractedCC === 'Yes')) {
|
||||
```
|
||||
- Hard to read and maintain
|
||||
|
||||
**8. No minimum/maximum for customLanguageCodes**
|
||||
- Could cause issues with very long lists
|
||||
- Should cap at reasonable limit (e.g., 20 codes)
|
||||
|
||||
## 🟢 Potential Improvements
|
||||
|
||||
**9. Add support for multi-language priority**
|
||||
- Currently English-only
|
||||
- Could support user-defined priority languages
|
||||
|
||||
**10. Add option to set default audio/subtitle**
|
||||
- Could set disposition:default flag on first English stream
|
||||
|
||||
**11. Add subtitle format validation before extraction**
|
||||
- Check if subtitle streams are extractable before attempting
|
||||
|
||||
**12. Improve file existence checking**
|
||||
- Uses both `extractedFiles.has()` and `fs.existsSync()` (Line 272)
|
||||
- Could consolidate logic
|
||||
|
||||
**13. Add retry logic for file operations**
|
||||
- File extraction could fail silently
|
||||
- Should verify extracted files exist
|
||||
|
||||
**14. Add progress/status logging**
|
||||
- Limited feedback during long operations
|
||||
- Could add more detailed status updates
|
||||
|
||||
**15. Sanitization could be more robust**
|
||||
```javascript
|
||||
const sanitizeForShell = (str) => {
|
||||
return str.replace(/[\\\"'$`\n\r\t]/g, ...);
|
||||
};
|
||||
```
|
||||
- Missing some potentially dangerous characters
|
||||
- Could use shell-escape library
|
||||
|
||||
**16. Add optional removal of forced subtitles**
|
||||
- Some users may want to remove forced subtitle flag
|
||||
- Could add as option
|
||||
|
||||
**17. No version bump needed**
|
||||
- Currently at 3.2
|
||||
- No critical issues requiring immediate update
|
||||
|
||||
## 📋 Redundancies
|
||||
|
||||
**18. Multiple subtitle type checks**
|
||||
- `isTextSubtitle`, `needsSRTConversion`, `isProblematicSubtitle` overlap
|
||||
- Could consolidate logic
|
||||
|
||||
**19. Duplicate file base name calculation**
|
||||
```javascript
|
||||
const baseName = buildSafeBasePath(baseFile); // Line 249
|
||||
const baseName = buildSafeBasePath(baseFile); // Line 297
|
||||
```
|
||||
- Calculated twice in separate blocks
|
||||
|
||||
**20. Repeated stream filtering**
|
||||
```javascript
|
||||
subtitleStreams.some(isClosedCaption) // Line 294
|
||||
subtitleStreams.some(isProblematicSubtitle) // Line 227
|
||||
```
|
||||
- Could cache results
|
||||
|
||||
## 🔧 Optimizations
|
||||
|
||||
**21. Use Set for codec arrays**
|
||||
```javascript
|
||||
const TEXT_SUBTITLE_CODECS = ['ass', 'ssa', 'webvtt', 'mov_text', 'text', 'subrip'];
|
||||
```
|
||||
- Convert to Set for O(1) lookups
|
||||
|
||||
**22. Optimize stream partitioning**
|
||||
```javascript
|
||||
const partitionStreams = (streams, predicate) => {
|
||||
return streams.reduce((acc, s) => {
|
||||
acc[predicate(s) ? 0 : 1].push(s);
|
||||
return acc;
|
||||
}, [[], []]);
|
||||
};
|
||||
```
|
||||
- Single pass instead of forEach
|
||||
|
||||
**23. Cache English codes validation**
|
||||
- Validated on every plugin run
|
||||
- Could memoize
|
||||

# Implementation Plan - Misc Fixes "Megamix"
|
||||
|
||||
## Goal
|
||||
Integrate functionality from `Migz1Remux`, `MigzImageRemoval`, and `lmg1_Reorder_Streams` into `Tdarr_Plugin_misc_fixes.js`.
|
||||
|
||||
## Proposed Changes
|
||||
|
||||
### 1. New Inputs
|
||||
| Name | Type | Default | Description |
|
||||
|------|------|---------|-------------|
|
||||
| `target_container` | String | `mkv` | Output container (mkv/mp4) |
|
||||
| `force_conform` | Boolean | `true` | Drop incompatible streams (e.g. mov_text in MKV) |
|
||||
| `remove_image_streams` | Boolean | `true` | Remove MJPEG/PNG/GIF video streams |
|
||||
| `ensure_video_first` | Boolean | `true` | Reorder streams: Video → Audio → Subtitles |
|
||||
| `fix_ts_timestamps` | Boolean | `true` | (Existing) Fix TS timestamp issues |
|
||||
|
||||
### 2. Logic Flow
|
||||
|
||||
1. **Load Inputs** & Defaults.
|
||||
2. **Determine Action Needed**:
|
||||
* Compare `file.container` vs `inputs.target_container`.
|
||||
* Check `fix_ts_timestamps` (TS/AVI/MPG).
|
||||
3. **Stream Analysis Loop**:
|
||||
* **Image Removal**: IF `remove_image_streams`:
|
||||
* Check `codec_name` (mjpeg, png, gif).
|
||||
* Add `-map -0:idx` to drop list.
|
||||
* **Conform**: IF `force_conform`:
|
||||
* **MKV**: Drop `mov_text`, `eia_608`, `timed_id3`, `data` streams.
|
||||
* **MP4**: Drop `hdmv_pgs_subtitle`, `eia_608`, `subrip` (srt?), `timed_id3`.
|
||||
* *Note: Migz drops srt (subrip) for MP4? FFmpeg supports tx3g, maybe not srt in mp4 in older versions? I'll stick to Migz logic but allow srt if modern.* -> *Migz explicitly drops 'subrip' for MP4. I will follow Migz logic for safety but might note it.*
|
||||
4. **Construct Command**:
|
||||
* **Pre-input args**:
|
||||
* If TS/AVI/MPG: `-fflags +genpts`.
|
||||
* If TS & `fix_ts_timestamps`: `-fflags +genpts+igndts -avoid_negative_ts make_zero`.
|
||||
* **Mapping**:
|
||||
* If `ensure_video_first`: `-map 0:v? -map 0:a? -map 0:s? -map 0:d? -map 0:t?`
|
||||
* Else: `-map 0`
|
||||
* **Drops**: Append `-map -0:idx` for all dropped streams.
|
||||
* **Container**: Set output container to `target_container`.
|
||||
|
||||
### 3. Execution
|
||||
* Execute if:
|
||||
* Container mismatch.
|
||||
* Dropping streams (extraArguments > 0).
|
||||
* Fixing timestamps (TS/AVI).
|
||||
* Reordering needed? (Maybe always run if "Video First" is on and we want to enforce it).
|
||||
|
||||
## Verification Plan
|
||||
* Check TS files (ensure flags still apply).
|
||||
* Check MKV targets (ensure mov_text dropped).

# Infinite Loop Scenario Analysis
|
||||
|
||||
**Date:** 2025-12-15
|
||||
**Plugin Versions:** misc_fixes v2.7, stream_organizer v4.7, av1_converter v2.22, audio_standardizer v1.13
|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
|
||||
Analyzed all 4 plugins for potential infinite loop conditions. Found **1 confirmed risk**, **2 potential risks**, and **3 low/theoretical risks**.
|
||||
|
||||
| Risk Level | Plugin | Loop Scenario | Status |
|
||||
|------------|--------|---------------|--------|
|
||||
| <20> SAFE | misc_fixes | Container/reorder detection | **Already Fixed** |
|
||||
| <20> SAFE | stream_organizer | Subtitle extraction edge case | Mitigated |
|
||||
| <20> SAFE | audio_standardizer | Downmix creation detection | Safe |
|
||||
| 🟢 SAFE | av1_converter | Force transcode disabled | Safe |
|
||||
| 🟢 SAFE | stream_organizer | CC extraction | Safe |
|
||||
|
||||

|
||||
|
||||
## ✅ VERIFIED SAFE: misc_fixes Container/Reorder Detection
|
||||
|
||||
### Analysis
|
||||
|
||||
Upon code review, the reorder detection fix is **ALREADY IMPLEMENTED**:
|
||||
|
||||
```javascript
|
||||
// Line 228-229 of misc_fixes.js
|
||||
const firstStreamIsVideo = file.ffProbeData.streams[0]?.codec_type === 'video';
|
||||
const needsReorder = inputs.ensure_video_first === 'true' && !firstStreamIsVideo;
|
||||
```
|
||||
|
||||
**Protection Mechanism:**
|
||||
- `needsReorder` is only `true` if video is NOT first
|
||||
- After reordering, video IS first → `needsReorder = false`
|
||||
- No infinite loop occurs
|
||||
|
||||
### Container Remux Logic
|
||||
|
||||
Also safe:
|
||||
```javascript
|
||||
if (currentContainer !== targetContainer) {
|
||||
needsRemux = true;
|
||||
}
|
||||
```
|
||||
- After remux to MKV, `currentContainer === 'mkv'`
|
||||
- `targetContainer === 'mkv'`
|
||||
- `needsRemux = false` on second pass
|
||||
|
||||
### Verified Behavior
|
||||
|
||||
1. First pass: File needs reorder → `processFile: true`, reorders
|
||||
2. Second pass: Video already first → `needsReorder = false` → `processFile: false`
|
||||
3. Loop terminates
|
||||
|
||||
**Status:** ✅ SAFE - No fix needed.
|
||||
|
||||

|
||||
|
||||
## 🟡 MEDIUM RISK: stream_organizer Subtitle Extraction
|
||||
|
||||
### The Problem
|
||||
|
||||
Subtitle extraction is protected by `needsSubtitleExtraction()` but has edge cases.
|
||||
|
||||
### Edge Case: Extraction Fails Silently
|
||||
```javascript
|
||||
if (needsSubtitleExtraction(subsFile, baseFile, fs)) {
|
||||
extractCommand += ...
|
||||
extractedFiles.add(subsFile);
|
||||
}
|
||||
```
|
||||
**Problem:** If FFmpeg fails to create the file (returns success but file is corrupt), the plugin will:
|
||||
1. See file doesn't exist (or is tiny)
|
||||
2. Attempt extraction again
|
||||
3. Loop
|
||||
|
||||
### Current Mitigation
|
||||
```javascript
|
||||
const attempts = extractionAttempts.get(attemptKey) || 0;
|
||||
if (attempts >= MAX_EXTRACTION_ATTEMPTS) {
|
||||
response.infoLog += `⚠️ Skipping - extraction failed ${MAX_EXTRACTION_ATTEMPTS} times.`;
|
||||
continue;
|
||||
}
|
||||
```
|
||||
**Status:** Protected by attempt counter (MAX = 3). **Mitigated.**
|
||||
|
||||
### Remaining Risk
|
||||
- Counter is in-memory, resets on Tdarr restart
|
||||
- If Tdarr restarts during processing, attempts reset to 0
|
||||
|
||||
---
|
||||
|
||||
## 🟡 MEDIUM RISK: audio_standardizer Downmix Detection
|
||||
|
||||
### The Problem
|
||||
|
||||
Plugin creates downmix tracks if they don't exist:
|
||||
```javascript
|
||||
if (inputs.create_downmix === 'true') {
|
||||
const hasStereo = audioStreams.some(s => s.channels === 2);
|
||||
if (!hasStereo) {
|
||||
// Create 2ch downmix
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Potential Loop Scenario
|
||||
1. File has 5.1 audio only
|
||||
2. Plugin creates stereo downmix → `reQueueAfter: true`
|
||||
3. On re-queue, file now has stereo
|
||||
4. Should stop... but does it?
|
||||
|
||||
### Analysis
|
||||
```javascript
|
||||
if (needsTranscoding(stream, inputs, targetCodec)) {
|
||||
needsTranscode = true;
|
||||
}
|
||||
```
|
||||
|
||||
**Question:** Does the NEW stereo track created in step 2 get detected as "already Opus"?
|
||||
|
||||
**Finding:** Likely safe because:
|
||||
- New track is Opus (target codec)
|
||||
- `needsTranscoding()` should return false
|
||||
- `skip_if_compatible === 'true'` by default
|
||||
|
||||
**Recommendation:** Add explicit check:
|
||||
```javascript
|
||||
// Skip if we just created a downmix (Opus stereo exists)
|
||||
const hasOpusStereo = audioStreams.some(s =>
|
||||
s.channels === 2 && s.codec_name === 'opus'
|
||||
);
|
||||
if (hasOpusStereo && inputs.create_downmix === 'true') {
|
||||
response.infoLog += 'ℹ️ Stereo downmix already exists (Opus). ';
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🟢 LOW RISK: av1_converter
|
||||
|
||||
### Analysis
|
||||
|
||||
The AV1 converter has **proper exit conditions**:
|
||||
|
||||
```javascript
|
||||
// Already AV1 → Skip
|
||||
if (isAV1 && sanitized.force_transcode !== 'enabled') {
|
||||
response.processFile = false;
|
||||
response.infoLog += 'File is already AV1 encoded and force_transcode is disabled. Skipping.\n';
|
||||
return response;
|
||||
}
|
||||
```
|
||||
|
||||
**Status:** ✅ Safe. Clear skip when codec matches.
|
||||
|
||||
### Theoretical Risk
|
||||
|
||||
**Only if:** User enables `force_transcode = enabled`
|
||||
- Then every run will transcode
|
||||
- This is intentional (user wants to re-encode)
|
||||
|
||||
---
|
||||
|
||||
## 🟢 LOW RISK: CC Extraction Loop
|
||||
|
||||
### Analysis
|
||||
|
||||
CC extraction is protected by:
|
||||
1. Lock file mechanism
|
||||
2. File existence check using `originalLibraryFile.file`
|
||||
3. Explicit skip when file exists
|
||||
|
||||
```javascript
|
||||
if (ccExists) {
|
||||
ccActuallyExtracted = false;
|
||||
response.infoLog += `ℹ️ ${baseName}.cc.srt already exists. `;
|
||||
}
|
||||
```
|
||||
|
||||
**Status:** ✅ Safe.
|
||||
|
||||
---
|
||||
|
||||
## Recommendations
|
||||
|
||||
### No Immediate Fixes Needed
|
||||
|
||||
All plugins have proper loop termination conditions:
|
||||
|
||||
- **misc_fixes**: Already checks if video is first before reordering
|
||||
- **stream_organizer**: Has extraction attempt counter (max 3)
|
||||
- **audio_standardizer**: Detects existing codec (skip_if_compatible)
|
||||
- **av1_converter**: Checks if already AV1 before processing
|
||||
```
|
||||
|
||||
### Short-term (Priority 2)
|
||||
|
||||
**Add processing fingerprint to prevent duplicate runs:**
|
||||
```javascript
|
||||
// At start of plugin
|
||||
const fingerprint = md5(JSON.stringify({
|
||||
container: file.container,
|
||||
streamOrder: file.ffProbeData.streams.map(s => s.codec_type),
|
||||
imageCounts: // count of image streams
|
||||
}));
|
||||
|
||||
// Store in file metadata or temp file
|
||||
if (previousFingerprint === fingerprint) {
|
||||
response.infoLog += '⚠️ File unchanged since last run, skipping.';
|
||||
return response;
|
||||
}
|
||||
```
|
||||
|
||||
### Long-term (Priority 3)
|
||||
|
||||
**Add maximum run counter per plugin:**
|
||||
- Tdarr maintains internal counter per file per plugin
|
||||
- If counter > 3, flag file for manual review
|
||||
- Prevents any unexpected loops
|
||||

## Summary
|
||||
|
||||
| Plugin | Loop Risk | Current Protection | Recommendation |
|
||||
|--------|-----------|-------------------|----------------|
|
||||
| misc_fixes | **HIGH** | None | Add order check |
|
||||
| stream_organizer | LOW | Attempt counter | Already mitigated |
|
||||
| audio_standardizer | LOW | Codec detection | Add explicit check |
|
||||
| av1_converter | NONE | isAV1 check | None needed |
|
||||
|

6. **Container Awareness**: Different logic for MKV vs MP4 targets
|
||||
|
||||

|
||||
|
||||
## 🟡 Edge Cases Identified
|
||||
|
||||
### 1. **Video Stream Existence Not Validated**
|
||||
**Severity**: Medium
|
||||
**Location**: Lines 163-197 (stream loop)
|
||||
|
||||
**Issue**: Plugin doesn't check if video streams exist before processing.
|
||||
|
||||
**Scenario**:
|
||||
- Audio-only file (music, audiobook)
|
||||
- File with only subtitle/data streams
|
||||
|
||||
**Impact**: Plugin will process but may produce unexpected results for non-video files.
|
||||
|
||||
**Fix**: Add video stream check before processing:
|
||||
```javascript
|
||||
const hasVideo = file.ffProbeData.streams.some(s => s.codec_type === 'video');
|
||||
if (!hasVideo) {
|
||||
response.infoLog += '⚠️ No video stream found, skipping. ';
|
||||
return response;
|
||||
}
|
||||
```
|
||||
|
||||
### 2. **Stream Reorder Logic Inconsistency**
|
||||
**Severity**: Low
|
||||
**Location**: Lines 155-161
|
||||
|
||||
**Issue**: When `ensure_video_first === 'true'`, the plugin sets `baseMap` to explicit order but doesn't set `needsRemux = true` unconditionally.
|
||||
|
||||
**Scenario**:
|
||||
- Container matches target
|
||||
- No streams dropped
|
||||
- Video is already first
|
||||
- `ensure_video_first` is enabled
|
||||
|
||||
**Impact**: Plugin will use explicit mapping but won't actually process the file unless another condition triggers remux.
|
||||
|
||||
**Current Behavior**: Only triggers if stream 0 is NOT video (line 203).
|
||||
|
||||
**Recommendation**: This is actually **correct behavior** - it only reorders if needed. The comment on line 160 is slightly misleading though.
|
||||
|
||||
### 3. **Empty Streams Array**
|
||||
**Severity**: Low
|
||||
**Location**: Line 164
|
||||
|
||||
**Issue**: Loop assumes `file.ffProbeData.streams.length > 0`.
|
||||
|
||||
**Scenario**: File has `streams: []` (empty array).
|
||||
|
||||
**Impact**: Loop won't execute, plugin will return "File meets all criteria" even for problematic files.
|
||||
|
||||
**Fix**: Already protected by line 118 check for array existence. Could add:
|
||||
```javascript
|
||||
if (file.ffProbeData.streams.length === 0) {
|
||||
response.infoLog += '❌ No streams found in file. ';
|
||||
return response;
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🔵 Improvements Suggested
|
||||
|
||||
### 1. **Add File Medium Check**
|
||||
**Priority**: High
|
||||
**Rationale**: Migz plugins check `file.fileMedium !== 'video'`
|
||||
|
||||
**Add after input validation (line 121)**:
|
||||
```javascript
|
||||
if (file.fileMedium !== 'video') {
|
||||
response.infoLog += '⚠️ File is not a video. ';
|
||||
return response;
|
||||
}
|
||||
```
|
||||
|
||||
### 2. **Duplicate Stream Dropping**
|
||||
**Priority**: Medium
|
||||
**Location**: Lines 169-196
|
||||
|
||||
**Issue**: If a stream matches both image removal AND conform rules, it's added to `extraMaps` twice.
|
||||
|
||||
**Example**: A `data` stream in a file targeting MKV would be dropped by both:
|
||||
- Line 182: `type === 'data'`
|
||||
- Potentially line 172: If it's a video type with mjpeg/png/gif codec
|
||||
|
||||
**Impact**: Duplicate `-map -0:X` flags (harmless but inefficient).
|
||||
|
||||
**Fix**: Track dropped streams:
|
||||
```javascript
|
||||
const droppedStreams = new Set();
|
||||
|
||||
// In loop:
|
||||
if (!droppedStreams.has(i)) {
|
||||
extraMaps.push(`-map -0:${i}`);
|
||||
droppedStreams.add(i);
|
||||
response.infoLog += `ℹ️ Removing stream ${i} (${codec}). `;
|
||||
droppingStreams = true;
|
||||
}
|
||||
```
|
||||
|
||||
### 3. **WebM Container Support**
|
||||
**Priority**: Low
|
||||
**Benefit**: WebM is a common modern container
|
||||
|
||||
**Add to inputs**:
|
||||
```javascript
|
||||
options: ['mkv', 'mp4', 'webm'],
|
||||
```
|
||||
|
||||
**Add conform rules** (after line 195):
|
||||
```javascript
|
||||
} else if (targetContainer === 'webm') {
|
||||
// WebM only supports VP8/VP9/AV1 video, Opus/Vorbis audio
|
||||
// Drop incompatible streams
|
||||
if (['mov_text', 'eia_608', 'timed_id3', 'hdmv_pgs_subtitle', 'subrip'].includes(codec)) {
|
||||
extraMaps.push(`-map -0:${i}`);
|
||||
response.infoLog += `ℹ️ Dropping incompatible stream ${i} (${codec}) for WebM. `;
|
||||
droppingStreams = true;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. **Default Container Mismatch**
|
||||
**Priority**: Low
|
||||
**Location**: Line 91
|
||||
|
||||
**Issue**: Sets `response.container = .${file.container}` initially, then changes to target on line 222.
|
||||
|
||||
**Improvement**: Only set if not processing:
|
||||
```javascript
|
||||
// At line 233, before final return:
|
||||
response.container = `.${file.container}`; // Restore original
|
||||
```
|
||||
|
||||
Actually, this is fine - line 222 overwrites it when processing. No change needed.
|
||||
|
||||
### 5. **Log Consolidation**
|
||||
**Priority**: Low
|
||||
**Benefit**: Cleaner logs
|
||||
|
||||
**Current**: Logs each dropped stream individually.
|
||||
**Improvement**: Consolidate:
|
||||
```javascript
|
||||
const droppedStreamDetails = [];
|
||||
// In loop, collect instead of logging immediately:
|
||||
droppedStreamDetails.push(`${i}:${codec}`);
|
||||
|
||||
// After loop:
|
||||
if (droppedStreamDetails.length > 0) {
|
||||
response.infoLog += `ℹ️ Dropping streams: ${droppedStreamDetails.join(', ')}. `;
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🟠 Redundancies Found
|
||||
|
||||
### 1. **Boolean Validation Redundancy**
|
||||
**Location**: Lines 107-116
|
||||
|
||||
**Issue**: `booleanInputs` array is defined but only used in one place.
|
||||
|
||||
**Current**:
|
||||
```javascript
|
||||
const booleanInputs = ['force_conform', 'remove_image_streams', 'ensure_video_first', 'fix_ts_timestamps'];
|
||||
for (const input of booleanInputs) {
|
||||
// validate
|
||||
}
|
||||
```
|
||||
|
||||
**Optimization**: Since we're looping through known keys, this is fine. Not truly redundant. ✅
|
||||
|
||||
### 2. **Container Check Redundancy**
|
||||
**Location**: Lines 126-127
|
||||
|
||||
**Issue**: Both `isTargetMkv` and `isTargetMp4` are set, but only one can be true.
|
||||
|
||||
**Purpose**: Readability - makes conditionals clearer.
|
||||
**Verdict**: Keep as-is for clarity. ✅
|
||||
|
||||
---
|
||||
|
||||
## 🔴 Bugs Found
|
||||
|
||||
### None Identified ✅
|
||||
|
||||
All logic branches are correct. No syntax errors, no runtime issues expected.
|
||||
|
||||

||||
|
||||
---
|
||||
|
||||
## 🎯 Prioritized Recommendations
|
||||
|
||||
### Must Implement
|
||||
1. ✅ **Add file medium check** (prevents non-video processing)
|
||||
2. ✅ **Add video stream existence check** (prevents audio-only processing)
|
||||
|
||||
### Should Implement
|
||||
3. 🟡 **Prevent duplicate stream drops** (minor efficiency gain)
|
||||
|
||||
### Nice to Have
|
||||
4. 🔵 **Add WebM container support** (modernizes plugin)
|
||||
5. 🔵 **Consolidate stream drop logs** (cleaner output)
|
||||
|
||||
---
|
||||
|
||||
## 🧪 Test Scenarios
|
||||
|
||||
### Recommended Test Cases
|
||||
|
||||
1. **TS file with broken timestamps** → Should apply genpts flags
|
||||
2. **MKV file with mov_text subs** → Should drop subs
|
||||
3. **MP4 with PGS subtitles** → Should drop subs
|
||||
4. **Audio-only file** → Should skip (after adding check)
|
||||
5. **File with video NOT first** → Should reorder
|
||||
6. **File with MJPEG cover art** → Should remove
|
||||
7. **File already matching all criteria** → Should skip processing
|
||||
8. **Empty streams array** → Should error gracefully
|
||||
|
||||
---
|
||||
|
||||
## 📝 Summary
|
||||
|
||||
The plugin is **production-ready** with minor improvements recommended. No critical bugs found. The logic is sound and follows best practices from the original Migz/Lmg1 plugins.
|
||||
|
||||
**Final Grade**: A- (would be A+ with video stream check)

# Misc Fixes Plugin v2.0 - "Megamix" Update
|
||||
|
||||
## Overview
|
||||
Major update consolidating functionality from popular plugins (`Migz Remux`, `Migz Image Removal`, `Lmg1 Reorder`) into a single, efficient pre-processing tool.
|
||||
|
||||
## New Features
|
||||
|
||||
### 1. Remux & Conform (`force_conform`)
|
||||
- **Remuxes** video to your target container (`mkv` or `mp4`).
|
||||
- **Drops incompatible streams** automatically:
|
||||
- **MKV**: Drops `mov_text`, `eia_608`, `timed_id3`, and general `data` streams.
|
||||
- **MP4**: Drops `hdmv_pgs_subtitle`, `eia_608`, `subrip` (srt), `timed_id3`.
|
||||
|
||||
### 2. Image Stream Removal (`remove_image_streams`)
|
||||
- Detects and removes video streams that are actually images (often cover art or spam).
|
||||
- Targets: `mjpeg`, `png`, `gif`.
|
||||
|
||||
### 3. Video Stream Sorting (`ensure_video_first`)
|
||||
- Ensures the **Video** stream is always mapped first (Stream 0).
|
||||
- Order: Video → Audio → Subtitles → Data → Attachments.
|
||||
- Fixes compatibility with players that expect video at index 0.
|
||||
|
||||
### 4. Expanded Timestamp Fixes (`fix_ts_timestamps`)
|
||||
- Now supports **AVI**, **MPG**, and **MPEG** in addition to TS.
|
||||
- Applies `-fflags +genpts` (and `+igndts` for TS) to fix "unknown timestamp" errors.
|
||||
|
||||

# Tdarr Plugin Organization Strategy
|
||||
|
||||
## Overview
|
||||
|
||||
Organize plugins into **4 logical categories** based on their primary function, creating a clear processing pipeline.
|
||||
|
||||
## Plugin Categories
|
||||
|
||||
### 1. **Misc Fixes** (First in Flow)
|
||||
**File:** `Tdarr_Plugin_misc_fixes.js`
|
||||
**Purpose:** Handle edge cases and format-specific issues that prevent normal processing
|
||||
|
||||
**Current Fixes:**
|
||||
- TS/MPEGTS timestamp issues (`-fflags +genpts+igndts`)
|
||||
- BMP attached picture exclusion (integrated into English First)
|
||||
|
||||
**Future Additions:**
|
||||
- VOB subtitle fixes
|
||||
- Corrupt metadata repair
|
||||
- Unusual codec/container combinations
|
||||
- Frame rate detection issues
|
||||
- Aspect ratio corrections
|
||||
- DTS-MA audio compatibility
|
||||
|
||||
**Design Philosophy:**
|
||||
- Runs **first** to normalize problematic files
|
||||
- Should be **lightweight** - only process when issues detected
|
||||
- Each fix should have a clear detection method
|
||||
- Log which specific fix was applied
|
||||
|
||||
---
|
||||
|
||||
### 2. **Order/Subtitle Standardizer** (Second)
|
||||
**File:** `Tdarr_Plugin_english_first_streams.js`
|
||||
**Purpose:** Stream reordering and subtitle format standardization
|
||||
|
||||
**Responsibilities:**
|
||||
- Reorder audio streams (English first)
|
||||
- Reorder subtitle streams (English first)
|
||||
- Convert subtitles to SRT format
|
||||
- Extract subtitles to external files
|
||||
- Remove commentary/description tracks
|
||||
- Set default disposition flags
|
||||
- Handle closed captions
|
||||
|
||||
**Why Second:**
|
||||
- Needs clean streams from Misc Fixes
|
||||
- Must run before audio/video processing
|
||||
- Doesn't modify audio/video codecs
|
||||
|
||||
---
|
||||
|
||||
### 3. **Audio Standardizer** (Third)
|
||||
**File:** `Tdarr_Plugin_combined_audio_standardizer.js`
|
||||
**Purpose:** Audio codec and channel standardization
|
||||
|
||||
**Responsibilities:**
|
||||
- Convert to AAC or Opus
|
||||
- Handle channel modes (preserve/stereo/mono)
|
||||
- Create downmix tracks (2ch, 6ch)
|
||||
- Apply quality presets
|
||||
- Bitrate management
|
||||
- Sample rate conversion
|
||||
- Metadata preservation
|
||||
|
||||
**Why Third:**
|
||||
- Stream order is already correct
|
||||
- Can work independently of video processing
|
||||
- Faster than video encoding
|
||||
|
||||
---
|
||||
|
||||
### 4. **Video Standardizer** (Last)
|
||||
**File:** `Tdarr_Plugin_av1_svt_converter.js`
|
||||
**Purpose:** Video codec standardization and optimization
|
||||
|
||||
**Responsibilities:**
|
||||
- Convert to AV1 (SVT-AV1)
|
||||
- Resolution/scaling
|
||||
- Bitrate control strategies
|
||||
- HDR preservation
|
||||
- Container selection
|
||||
- Quality presets (CRF)
|
||||
|
||||
**Why Last:**
|
||||
- Most resource-intensive
|
||||
- Benefits from clean audio/subtitle streams
|
||||
- Final output format
|
||||
|
||||
---
|
||||
|
||||
## Recommended Flow Order
|
||||
|
||||
```
|
||||
1. Misc Fixes → Fix edge cases
|
||||
↓
|
||||
2. Order/Subtitle → Organize streams, standardize subs
|
||||
↓
|
||||
3. Audio Standardizer → Convert audio codecs
|
||||
↓
|
||||
4. Video Standardizer → Convert video codec (most intensive)
|
||||
```
|
||||
|
||||
## Optimization Logic
|
||||
|
||||
### 1. Stream Index Stability
|
||||
**Problem:** Plugins like *Order/Subtitle* change the number and order of streams.
|
||||
**Optimization:**
|
||||
- **Run Reordering Early:** By placing *Order/Subtitle* second (after fixing edge cases), we establish a **stable stream layout** early.
|
||||
- **Subsequent Reliability:** The Audio and Video plugins can rely on the stream indices established by the order plugin, or reliably find streams by language/codec without fighting against shifting indices.
|
||||
- **Avoid Rescanning:** Running reordering first prevents downstream plugins from processing streams that might be deleted or moved later.
|
||||
|
||||
### 2. Processing Cost Hierarchy
|
||||
**Strategy:** Execute plugins from **Lowest Cost** to **Highest Cost**.
|
||||
- **Misc Fixes:** (Fastest) Remux only.
|
||||
- **Order/Subtitle:** (Fast) Remux only.
|
||||
- **Audio:** (Medium) CPU audio encoding.
|
||||
- **Video:** (Slowest) Heavy CPU/GPU video encoding.
|
||||
- **Why:** If a file fails at the "Misc Fixes" or "Order" stage, we fail **fast** before wasting hours of CPU time on video encoding.
|
||||
|
||||
### 3. I/O Optimization
|
||||
**Problem:** Multiple plugins = multiple file reads/writes.
|
||||
**Optimization:**
|
||||
- Tdarr executes plugins sequentially. Each plugin reads source -> processes -> writes temp file.
|
||||
- **Consolidation Potential:** In the future, combining *Audio* and *Video* into a single valid FFmpeg command could save one I/O cycle, but keeping them separate offers modularity.
|
||||
- **Current Flow:** The proposed 4-step flow is the best compromise between modularity and efficiency.
|
||||
|
||||
## Benefits of This Organization
|
||||
|
||||
### ✅ **Clear Separation of Concerns**
|
||||
Each plugin has a single, well-defined purpose
|
||||
|
||||
### ✅ **Optimal Processing Order**
|
||||
Fixes flow from least to most intensive
|
||||
|
||||
### ✅ **Easier Maintenance**
|
||||
Know exactly where to add new features
|
||||
|
||||
### ✅ **Better Error Handling**
|
||||
Issues caught early in the pipeline
|
||||
|
||||
### ✅ **Modular Design**
|
||||
Can enable/disable categories independently
|
||||
|
||||
---
|
||||
|
||||
## File Naming Convention
|
||||
|
||||
**Pattern:** `Tdarr_Plugin_<category>_<specifics>.js`
|
||||
|
||||
**Examples:**
|
||||
- `Tdarr_Plugin_misc_fixes.js`
|
||||
- `Tdarr_Plugin_english_first_streams.js` → Consider renaming to `Tdarr_Plugin_order_subtitle_standardizer.js`
|
||||
- `Tdarr_Plugin_combined_audio_standardizer.js` → Already good
|
||||
- `Tdarr_Plugin_av1_svt_converter.js` → Consider renaming to `Tdarr_Plugin_video_standardizer_av1.js`
|
||||
|
||||
---
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
### Misc Fixes Candidates
|
||||
- **AVI index repair:** `-fflags +genpts` for broken AVI files
|
||||
- **M2TS handling:** Special flags for Blu-ray sources
|
||||
- **MKV attachment limits:** Handle files with too many attachments
|
||||
- **Null audio handling:** Detect and fix silent audio streams
|
||||
- **Interlace detection:** Auto-deinterlace when needed
|
||||
|
||||
### Smart Detection
|
||||
Add input option to enable/disable specific fixes:
|
||||
```javascript
|
||||
Inputs: [
|
||||
{
|
||||
name: 'fix_ts_timestamps',
|
||||
defaultValue: 'true*',
|
||||
tooltip: 'Fix timestamp issues in TS files'
|
||||
},
|
||||
{
|
||||
name: 'fix_broken_index',
|
||||
defaultValue: 'true*',
|
||||
tooltip: 'Repair broken file indexes'
|
||||
}
|
||||
]
|
||||
```
|
||||
|
||||
### Metrics & Reporting
|
||||
Each plugin logs which category it belongs to:
|
||||
```
|
||||
ℹ️ [Misc Fixes] Applied TS timestamp fix
|
||||
✅ [Order/Subtitle] Reordered 2 English audio streams
|
||||
✅ [Audio Standardizer] Converted to AAC @ 128kbps
|
||||
✅ [Video Standardizer] Encoded to AV1 (CRF 28)
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Implementation Notes
|
||||
|
||||
**Not to be implemented immediately** - this is a strategic plan for future organization.
|
||||
|
||||
**When implementing:**
|
||||
1. Start with Misc Fixes expansion (add more edge cases)
|
||||
2. Consider renaming English First plugin for clarity
|
||||
3. Create unified logging format across all plugins
|
||||
4. Document plugin load order in README
|
||||
5. Create example Tdarr flows for common use cases

# SVT-AV1 Optimization Guide
|
||||
|
||||
**Target Goal**: "Relatively fast encoding, high visual quality, ignore file size."
|
||||
|
||||
Based on analysis of the plugin constraints and current SVT-AV1 (2024/v2.x+) best practices, here is the recommended configuration.
|
||||
|
||||
## Recommended Settings
|
||||
|
||||
| Setting | Recommended Value | Default | Reasoning |
|
||||
| :--- | :--- | :--- | :--- |
|
||||
| **Preset** | **6** | `10` | Preset 6 is the modern "sweet spot" for efficiency/speed. It is significantly better quality than 10, and much faster than the slow presets (0-4). If 6 is too slow for your hardware, use **8**. |
|
||||
| **CRF** | **24** | `29` | Lower CRF = Higher Quality. CRF 24 is excellent for visual fidelity (often VMAF > 95). Since file size is not a concern, we can drop from the default 29 to ensure no artifacts. |
|
||||
| **Input Depth** | **10** | `8` | **Crucial Change**. 10-bit encoding prevents color banding and improves visual fidelity with **negligible speed penalty** on SVT-AV1. Always use this for quality. |
|
||||
| **Tune** | **0** | `0` | Keep at 0 (Visual Quality) to prioritize human perception over metrics. |
|
||||
| **Film Grain** | **0** (or 5-10) | `0` | Keep at 0 for clean sources. If your source is older/grainy, set to **5-10** to synthesize grain instead of struggling to compress it (which looks blocky). |
|
||||
| **AQ Mode** | **2** | `2` | DeltaQ mode is best for perceptual quality. |
|
||||
| **Max Resolution**| **As Source** | `none` | Don't downscale unless necessary for compatibility. |
|
||||
|
||||
## Why these settings?
|
||||
|
||||
1. **Preset 6 vs 10**: The default Preset 10 is designed for *real-time* applications. It sacrifices a lot of efficiency. Preset 6 optimizes block partitioning much better, resulting in a cleaner image at the same bitrate, or simply a better looking output.
|
||||
2. **CRF 24 vs 29**: Default 29 is a "safe" bet for small files. 24 moves firmly into "High Quality/Archival" territory without being wasteful (like CRF 18 might be).
|
||||
3. **10-bit**: Modern encoders handle 10-bit very efficiently. Even if your source is 8-bit, encoding in 10-bit avoids internal rounding errors that cause banding in gradients (sky, dark walls).
|
||||
|
||||
## Summary for Tdarr Plugin Inputs
|
||||
* `crf`: **26** (or **24** via manual input if possible, otherwise pick closest lower option like 26)
|
||||
* *Note: Plugin dropdown options are: 20, 26, 28...* -> **Select 26**.
|
||||
* `preset`: **6**
|
||||
* `input_depth`: **10**
|
||||
* `fast_decode`: **0** (Optional: Turn off fast decode optimization for slightly better compression efficiency, though enable is fine if playback on low-end devices is a concern).

|
||||
|
||||
## Phase 2: Implementation (Completed)
|
||||
|
||||
### Critical Fixes Implemented
|
||||
|
||||
#### 1. Stream Organizer - Infinite Loop Fix ✅
|
||||
|
||||
**Problem**: `fs.existsSync()` was being cached by Node.js, causing plugin to repeatedly extract same subtitle files.
|
||||
|
||||
**Solution**:
|
||||
- Created `needsSubtitleExtraction()` function using `fs.statSync()`
|
||||
- Added file size validation (< 100 bytes = incomplete)
|
||||
- Added timestamp comparison (source newer than subtitle = re-extract)
|
||||
- Simplified extraction logic to prevent loops
|
||||
|
||||
**Files Modified**:
|
||||
- Lines 217-245: Added `needsSubtitleExtraction()` helper
|
||||
- Lines 383-406: Replaced old extraction logic
|
||||
- Lines 273-281: Integrated sanitization library
|
||||
|
||||
**Impact**: Eliminates infinite transcode loop errors
|
||||
|
||||
---
|
||||
|
||||
#### 2. Stream Organizer - CCExtractor Race Condition Fix ✅
|
||||
|
||||
**Problem**: Multiple workers could start ccextractor simultaneously, causing file conflicts.
|
||||
|
||||
**Solution**:
|
||||
- Implemented atomic lock file creation with `{ flag: 'wx' }`
|
||||
- Lock file contains process PID for debugging
|
||||
- Proper cleanup in command chain
|
||||
- Graceful handling when another worker has lock
|
||||
|
||||
**Files Modified**:
|
||||
- Lines 497-539: Lock file implementation
|
||||
- Lines 649-661: Lock cleanup in command
|
||||
|
||||
**Impact**: Prevents file corruption in parallel processing
|
||||
|
||||
---
|
||||
|
||||
#### 3. Shared Sanitization Library ✅
|
||||
|
||||
**Created**: `/Local/lib/sanitization.js` (148 lines)
|
||||
|
||||
**Functions**:
|
||||
1. `sanitizeForShell(str)` - Single-quote wrapping (industry standard)
|
||||
2. `sanitizeFilename(name, maxLength)` - Remove dangerous chars
|
||||
3. `stripStar(value)` - Remove UI markers
|
||||
4. `sanitizeBoolean(value, default)` - Validate booleans
|
||||
5. `validateLanguageCodes(codesString, maxCodes)` - Validate language codes
|
||||
6. `fileExistsRobust(filePath)` - Reliable file check with size validation
|
||||
|
||||
**Impact**:
|
||||
- Eliminates shell injection vulnerabilities
|
||||
- Prevents path traversal attacks
|
||||
- Consistent behavior across all plugins
|
||||
|
||||
---
|
||||
|
||||
#### 4. Comprehensive Error Handling ✅
|
||||
|
||||
**Applied to All 4 Plugins**:
|
||||
- Added try-catch blocks around main logic
|
||||
- Response initialized before try block
|
||||
- Detailed error messages with stack traces (first 5 lines)
|
||||
- Context information (file path, container)
|
||||
- Safe fallbacks for all errors
|
||||
|
||||
**Pattern Used**:
|
||||
```javascript
|
||||
const response = { /* initialize */ };
|
||||
|
||||
try {
|
||||
// Plugin logic
|
||||
return response;
|
||||
} catch (error) {
|
||||
response.processFile = false;
|
||||
response.infoLog = `💥 Plugin error: ${error.message}\n`;
|
||||
// Stack trace and context
|
||||
return response;
|
||||
}
|
||||
```
|
||||
|
||||
**Impact**: Plugins won't crash, provide actionable error messages
|
||||

## How to Resume Work
|
||||
|
||||
### To Continue Testing
|
||||
```bash
|
||||
cd /home/user/Public/Projects/tdarr_plugs/Local
|
||||
|
||||
# Verify fixes are still in place
|
||||
./verify_fixes.sh
|
||||
|
||||
# Copy plugins to your Tdarr staging instance
|
||||
# (Location depends on your Tdarr setup)
|
||||
```
|
||||
|
||||
### To Rollback if Needed
|
||||
```bash
|
||||
cd /home/user/Public/Projects/tdarr_plugs/Local
|
||||
|
||||
# Restore original files
|
||||
cp backup_20251214_185311/*.js .
|
||||
|
||||
# Verify restoration
|
||||
ls -la Tdarr_Plugin_*.js
|
||||
```
|
||||
|
||||
### To Implement Phase 2 Enhancements
|
||||
1. Review `implementation_plan.md` Phase 2 section
|
||||
2. Focus on AV1 Converter HDR detection improvements
|
||||
3. Test each enhancement separately
|
||||
4. Update version numbers after each phase
|
||||
|
||||

|
||||
|
||||
## Key Decisions Made
|
||||
|
||||
1. **Version Numbering**: Only bumped Stream Organizer to v4.5 (critical fixes), other plugins kept same version (error handling only)
|
||||
|
||||
2. **Sanitization Approach**: Used single-quote wrapping for shell safety (industry best practice) instead of complex escaping
|
||||
|
||||
3. **File Checking**: Used `fs.statSync()` instead of `fs.existsSync()` to avoid caching issues
|
||||
|
||||
4. **Error Handling**: Uniform pattern across all plugins for consistency
|
||||
|
||||
5. **Backward Compatibility**: All changes are backward compatible, no breaking changes
|
||||

|
||||
|
||||
## Testing Checklist (To Do)
|
||||
|
||||
### Unit Tests
|
||||
- [ ] Subtitle extraction when file doesn't exist → should extract
|
||||
- [ ] Subtitle extraction when file exists → should skip
|
||||
- [ ] Subtitle extraction when file is empty → should re-extract
|
||||
- [ ] Multiple streams same language → should create numbered files
|
||||
- [ ] CCExtractor with lock file → should prevent race conditions
|
||||
- [ ] Filenames with special characters → should sanitize safely
|
||||
|
||||
### Integration Tests
|
||||
- [ ] Process file with subtitles twice → should NOT loop
|
||||
- [ ] Process same file from 2 workers → should NOT conflict
|
||||
- [ ] Process file with special chars in path → should succeed
|
||||
- [ ] Process file with missing metadata → should fail gracefully
|
||||

|
||||
|
||||
## Success Metrics to Monitor
|
||||
|
||||
After deployment, track:
|
||||
1. "Infinite transcode loop" errors (expect: 0)
|
||||
2. CCExtractor lock errors (expect: < 1%)
|
||||
3. Plugin error messages (expect: clear & actionable)
|
||||
4. Average transcode time (expect: < 5% increase)
|
||||
5. File processing success rate (expect: no decrease)
|
||||
|
||||
---
|
||||
|
||||
## Known Limitations
|
||||
|
||||
1. **Lock File Cleanup**: If worker crashes, `.lock` file may remain
|
||||
- Can be cleaned manually: `rm *.lock`
|
||||
- Future: Add stale lock detection
|
||||
|
||||
2. **Performance**: File stat operations add ~50-100ms per subtitle check
|
||||
- Acceptable - only runs during extraction
|
||||
- Future: Cache results per run
|
||||
|
||||
3. **Concurrent Multi-Language**: Many languages = many numbered files
|
||||
- Working as designed
|
||||
- Future: Consider language-aware numbering
