使用 yt-dlp 与 FFmpeg 下载、保存、检查或提取公开视频、独立音频、最佳原语言字幕及最高质量原始封面，并为后续字幕翻译准备确定性的隐藏输入。Use when Codex is asked to inspect formats, download permitted media with its best source thumbnail, audio, and source subtitle when available, or prepare deterministic inputs for the video translation workflow; confirm quality, path, and filename before downloading.
