Trying to run ffmpeg command line myself, I got the below

Hallo!

I hit the same problem, but I am quite sure I am trying to merge video and audio.

$ youtube-dl -f 137+398 "https://www.youtube.com/watch?v=vZPOiMzUBCE"

ERROR: To ignore this, add a trailing '?' to the map.

137          mp4        1920x1080  1080p  380k , avc1.640028, 30fps, video only, 5.91MiB
398          mp4        audio only 720p  243k , 30fps, 3.53MiB

Is the "unknown codec" the problem?

ffmpeg on the command line says the following:

$ ffmpeg -y -i 'file:DJ Snake - Taki Taki (ft. Cardi B, Selena Gomez, Ozuna) (Letra) (Lyrics)-vZPOiMzUBCE.f248.webm' -i 'file:DJ Snake - Taki Taki (ft.

Hit the same error, as a word-around you can first list the formats by adding -F key, and then choose another format for download with -f, e.g. which does not have "video-only".
