<details>
<summary><strong>🧠 Click to view Transcoding Decision Engine implementation code</strong></summary>

```typescript
class TranscodingDecisionEngine {
  private compatibilityMatrix: CompatibilityMatrix;
  private costOptimizer: CostOptimizer;
  private performanceTracker: PerformanceTracker;

  async makeTranscodingDecision(
    file: MediaFile,
    targetEngines: TranscriptionEngine[]
  ): Promise<TranscodingDecision> {
    // 1. Analyze file characteristics
    const fileAnalysis = await this.analyzeFile(file);

    // 2. Check compatibility with each engine
    const compatibilityResults = await Promise.all(
      targetEngines.map((engine) =>
        this.checkCompatibility(fileAnalysis, engine)
      )
    );

    // 3. Calculate cost and performance metrics
    const metrics = await this.calculateMetrics(
      fileAnalysis,
      compatibilityResults
    );

    // 4. Apply business rules and constraints
    const decision = await this.applyBusinessRules(fileAnalysis, metrics);

    return {
      shouldTranscode: decision.needsTranscoding,
      targetFormat: decision.targetFormat,
      selectedEngine: decision.optimalEngine,
      estimatedCost: decision.cost,
      estimatedDuration: decision.duration,
      qualityScore: decision.qualityScore,
    };
  }

  private async checkCompatibility(
    fileAnalysis: FileAnalysis,
    engine: TranscriptionEngine
  ): Promise<CompatibilityResult> {
    const formatSupported = engine.supportedFormats.includes(
      fileAnalysis.format
    );
    const sizeWithinLimit = fileAnalysis.size <= engine.maxFileSize;
    const durationWithinLimit = fileAnalysis.duration <= engine.maxDuration;
    const languageSupported = engine.supportedLanguages.includes(
      fileAnalysis.language
    );

    return {
      engine: engine.id,
      compatible:
        formatSupported &&
        sizeWithinLimit &&
        durationWithinLimit &&
        languageSupported,
      formatSupported,
      sizeWithinLimit,
      durationWithinLimit,
      languageSupported,
      compatibilityScore: this.calculateCompatibilityScore({
        formatSupported,
        sizeWithinLimit,
        durationWithinLimit,
        languageSupported,
      }),
    };
  }
}
```

</details>

**Decision Criteria:**

- **Format Compatibility**: Check against engine-specific supported formats

- **Duration Limits**: Provider A (1 hour), Provider B (10 hours), Provider C (3 hours)
- **Language Support**: Verify language compatibility with target engine
- **Quality Requirements**: Maintain optimal quality for transcription

### 3. Large File Segmentation Strategy

**Challenge**: Processing files longer than 4 hours while maintaining transcription accuracy.

**Solution**: Implemented intelligent file segmentation with overlap handling.

<details>
<summary><strong>✂️ Click to view File Segmentation implementation code</strong></summary>

```typescript
class FileSegmentationService {
  private ffmpeg: FFmpegProcessor;
  private segmentAnalyzer: SegmentAnalyzer;

  async segmentLargeFile(
    file: MediaFile,
    maxSegmentDuration: number = 3 * 60 * 60 + 59 * 60 // 3h 59m
  ): Promise<FileSegment[]> {
    // 1. Analyze file for optimal segmentation points
    const segmentationPoints = await this.findOptimalSegmentationPoints(
      file,
      maxSegmentDuration
    );

    // 2. Create segments with overlap
    const segments = await this.createSegments(file, segmentationPoints);

    // 3. Process segments in parallel
    const processedSegments = await this.processSegmentsInParallel(segments);

    return processedSegments;
  }

  private async findOptimalSegmentationPoints(
    file: MediaFile,
    maxDuration: number
  ): Promise<number[]> {
    // Use FFmpeg to detect silence and speaker changes
    const silencePoints = await this.ffmpeg.detectSilence(file, {
      silenceThreshold: -30, // dB
      minSilenceDuration: 2.0, // seconds
    });

    // Find natural break points
    const breakPoints = await this.segmentAnalyzer.findNaturalBreaks(
      file,
      silencePoints,
      maxDuration
    );

    return breakPoints;
  }

  private async createSegments(
    file: MediaFile,
    breakPoints: number[]
  ): Promise<FileSegment[]> {
    const segments: FileSegment[] = [];
    const overlapDuration = 30; // 30 seconds overlap

    for (let i = 0; i < breakPoints.length - 1; i++) {
      const startTime = Math.max(0, breakPoints[i] - overlapDuration);
      const endTime = breakPoints[i + 1] + overlapDuration;

      const segment = await this.ffmpeg.extractSegment(file, {
        startTime,
        endTime,
        segmentIndex: i,
        includeOverlap: true,
      });

      segments.push(segment);
    }

    return segments;
  }
}
```

</details>

**Segmentation Benefits:**

- **Large File Support**: Handle files up to 10+ hours
- **Parallel Processing**: Process segments concurrently
- **Memory Efficiency**: Avoid loading entire large files into memory
- **Error Isolation**: Segment failures don't affect entire file
- **Progress Tracking**: Real-time progress updates per segment

### 4. Multi-Engine Transcription Orchestration

**Challenge**: Routing files to optimal transcription engines based on format, language, and size.

**Solution**: Implemented intelligent engine selection with automatic fallback. This orchestration pattern aligns with [multi-agent orchestration principles](/blog/ai-agent-orchestration-multi-agent-systems-2025) for complex AI workflows.

  private performanceTracker: PerformanceTracker;
  private fallbackManager: FallbackManager;

  async selectOptimalEngine(
    file: MediaFile,
    requirements: TranscriptionRequirements
  ): Promise<TranscriptionEngine> {
    // 1. Get available engines
    const availableEngines = await this.getAvailableEngines();

    // 2. Score each engine based on multiple criteria
    const engineScores = await Promise.all(
      availableEngines.map((engine) =>
        this.scoreEngine(engine, file, requirements)
      )
    );

    // 3. Select highest scoring engine
    const optimalEngine = this.selectHighestScoringEngine(engineScores);

    // 4. Set up fallback chain
    const fallbackChain = await this.fallbackManager.createFallbackChain(
      optimalEngine,
      engineScores
    );

    return {
      ...optimalEngine,
      fallbackChain,
    };
  }

  private async scoreEngine(
    engine: TranscriptionEngine,
    file: MediaFile,
    requirements: TranscriptionRequirements
  ): Promise<EngineScore> {
    // Format compatibility score
    const formatScore = this.calculateFormatScore(engine, file);

    // Performance score based on historical data
    const performanceScore = await this.performanceTracker.getPerformanceScore(
      engine
    );

    // Cost efficiency score
    const costScore = this.calculateCostScore(engine, file);

    // Language support score
    const languageScore = this.calculateLanguageScore(
      engine,
      requirements.language
    );

    // Quality score
    const qualityScore = this.calculateQualityScore(
      engine,
      requirements.quality
    );

    const totalScore =
      formatScore * 0.25 +
      performanceScore * 0.25 +
      costScore * 0.2 +
      languageScore * 0.15 +
      qualityScore * 0.15;

    return {
      engine: engine.id,
      totalScore,
      formatScore,
      performanceScore,
      costScore,
      languageScore,
      qualityScore,
    };
  }
}
```

</details>

**Engine Selection Logic:**

- **Provider B**: Large files (up to 5GB), 50+ formats, 100+ languages
- **Provider A**: Standard files (up to 2GB), 8 formats, 40+ languages
- **Provider C**: Real-time processing, 11 formats, 30+ languages
- **Automatic Fallback**: Switch engines on failure or unsupported formats

### 5. Real-Time Processing with Streaming

**Challenge**: Providing immediate feedback for long-running transcoding operations.

**Solution**: Implemented streaming transcoding with progress updates.

    const ws = this.websocketManager.getConnection(clientId);

    try {
      // Start transcoding with progress callbacks
      const transcodingProcess = await this.ffmpeg.transcodeWithProgress(
        file,
        options,
        (progress) => {
          // Send real-time progress updates
          ws.send(
            JSON.stringify({
              type: "progress",
              data: {
                percentage: progress.percentage,
                currentOperation: progress.currentOperation,
                estimatedTimeRemaining: progress.estimatedTimeRemaining,
                processedBytes: progress.processedBytes,
                totalBytes: progress.totalBytes,
              },
            })
          );
        }
      );

              qualityMetrics: result.qualityMetrics,
            },
          })
        );
      });

      // Handle errors
      transcodingProcess.on("error", (error) => {
        ws.send(
          JSON.stringify({
            type: "error",
            data: {
              success: false,
              error: error.message,
              retryable: error.retryable,
              suggestedAction: error.suggestedAction,
            },
          })
        );
      });
    } catch (error) {
      ws.send(
        JSON.stringify({
          type: "error",
          data: {
            success: false,
            error: error.message,
          },
        })
      );
    }
  }
}
```

  async processLargeFile(
    file: MediaFile,
    processor: (chunk: Buffer) => Promise<ProcessedChunk>
  ): Promise<ProcessedFile> {
    const processedChunks: ProcessedChunk[] = [];
    const totalChunks = Math.ceil(file.size / this.chunkSize);

    // Process file in streaming chunks
    for (let i = 0; i < totalChunks; i++) {

```typescript
class RealTimeProgressTracker {
  private websocketManager: WebSocketManager;
  private progressCalculator: ProgressCalculator;

  async trackTranscodingProgress(
    jobId: string,
    clientId: string,
    transcodingProcess: TranscodingProcess
  ): Promise<void> {
    const ws = this.websocketManager.getConnection(clientId);

    // Set up progress tracking
    transcodingProcess.on("progress", (progress) => {
      const progressUpdate = {
        jobId,
        timestamp: Date.now(),
        percentage: progress.percentage,
        currentOperation: progress.operation,
        estimatedTimeRemaining: this.progressCalculator.estimateTimeRemaining(
          progress.percentage,
          progress.elapsedTime
        ),
        processedBytes: progress.processedBytes,
        totalBytes: progress.totalBytes,
        processingSpeed: progress.processingSpeed,
      };

      ws.send(
        JSON.stringify({
          type: "progress",
          data: progressUpdate,
        })
      );
    });

    // Set up completion tracking
    transcodingProcess.on("complete", (result) => {
      ws.send(
        JSON.stringify({
          type: "complete",
          data: {
            jobId,
            success: true,
            result: result,
            totalProcessingTime: result.processingTime,
          },
        })
      );
    });

    // Set up error tracking
    transcodingProcess.on("error", (error) => {
      ws.send(
        JSON.stringify({
          type: "error",
          data: {
            jobId,
            success: false,
            error: error.message,
            retryable: error.retryable,
            suggestedAction: error.suggestedAction,
          },
        })
      );
    });
  }
}
```
