[IMPORTANT] Use TaskCreate to break ALL work into small tasks BEFORE starting — including tasks for each file read. This prevents context loss from long files. For simple tasks, AI MUST ask user whether to skip.
Quick Summary
Goal: Process multimedia files using FFmpeg for video/audio encoding, conversion, streaming, and filtering.
Workflow:
- Identify -- Match input to correct FFmpeg operation (convert, trim, merge, compress)
- Execute -- Run FFmpeg command with appropriate codec and quality settings
- Verify -- Check output file integrity and quality
Key Rules:
- Use tool selection table to pick correct FFmpeg operation
- Prefer hardware-accelerated encoding when available
- Always verify output file exists and is playable
Be skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%).
