The report provides only the Seal version, Android device details, URL, and yt-dlp error; it names no source files or tests. Start by reproducing the niconico live-video download with the supplied URL and determine how Seal packages or exposes yt-dlp WebSocket support. Done means the download works or the missing dependency is clearly reported as unsupported.
