The general issue is that some YouTube formats come as two separate streams. You can check what youtube-dl can discover by calling $ youtube-dl -F https://www.youtube.com/watch?v=mosPaiR-nrs I think the issue with youtube-dl is it claims the composite MP4 format is "best": > [...] > 22 mp4 1280x720 hd720 , avc1.64001F, mp4a.40.2@192k (best) but when using "-g", it doesn't deliver that best format, but two other URLs for a separate video and audio stream each. Note that, for this particular clip, there's no composite video+audio format available from YouTube with the highest resolution of 1920x1080. You could do $ ffmpeg -i $(youtube-dl -f "bestvideo" -g https://www.youtube.com/watch?v=mosPaiR-nrs) -i $(youtube-dl -f "bestaudio" -g https://www.youtube.com/watch?v=mosPaiR-nrs) -map 0:v -map 1:a [...] I believe I have done that and it worked. You may want to query those URLs first, put them in variables, and then hand these variables to ffmpeg. Note that, depending on what codecs your livestream requires, you might need to reencode, as YouTube likes delivering VP9 video and Opus audio, which may or may not suit your needs. Otherwise, use "bestvideo[ext=mp4]" and "bestaudio[ext=m4a]", if you prefer H.264 and AAC.
