ffmpeg can’t do the actual downloading, but if you do any converting/merging with youtube-dl it will use ffmpeg to do that. However ffmpeg can stream/download from rtmp and similar, but not YouTube, it’s mostly just for doing literally anything with video files (and sometimes images).
Can ffmpeg download from YouTube? I’ve been using YouTube DL which works great from CLI
