Python-FFmpeg Integration Reference

Use this skill when Python code is constructing FFmpeg commands, filters, ASS subtitles, or raw-frame pipes and the risk is a type, unit, color, or stream-mapping bug. This SKILL is a lean orchestrator; detailed tables and full code examples live in references/python-ffmpeg-reference.md.

When to Use

• ffmpeg-python stream graphs and filter arguments
• Python subprocess calls to FFmpeg
• drawtext, ASS/SSA, karaoke, and animated caption parameter mapping
• RGB/BGR/ASS color conversion bugs
• Seconds vs centiseconds vs milliseconds confusion
• Raw frame pipe I/O with NumPy/OpenCV
• Range/type validation before command execution

Critical Rules
