下载视频的技能

This skill appears to do what it says (download videos with yt-dlp and ffmpeg), but before installing or running it consider the following: - Network downloads: the script will download an FFmpeg ZIP from gyan.dev (a third‑party Windows build provider) and will run pip to install/upgrade yt-dlp. If you need higher assurance, manually install ffmpeg and yt-dlp and re-run the script. - Platform behavior: automatic ffmpeg download is implemented only for Windows; on other OSes the script exits and asks you to install ffmpeg yourself. SKILL.md's description about ffmpeg path differs from the script's implementation (script uses its own directory, not necessarily .trae/skills/...). - File writes: the script extracts files into its own directory and saves downloaded videos to ~/Downloads (or the user-specified output). Ensure you are comfortable with these write locations. - Legal/privacy: downloading content may violate terms of service or copyright law; avoid downloading protected content you do not have rights to. - Safety steps: review the downloaded ffmpeg zip URL manually, run the script in an isolated environment (VM or container) if possible, or install yt-dlp/ffmpeg yourself and run the script with network disabled to reduce risk. If you want me to, I can produce a hardened version that skips automatic ffmpeg download and instead checks for an existing ffmpeg on PATH and gives clearer paths for where it writes files.
