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).
I downloaded and converted (to mp3) so many hour long mixes. My car is pretty old but it can play mp3 from an SD card, so long mixes are great for roadtrips
Can ffmpeg download from YouTube? I’ve been using YouTube DL which works great from CLI
