Occasionally the youtube-dl on the tree is not totally up-to-date with the 
latest and greatest in git.  You can wait for a day or two and see if it gets 
updated in portage testing branch, or download it from git and run it from 
within a directory.

Theoretically, your config can run into trouble if the container format you 
have set to merge video and audio into, will not work with the video/audio 
extractors available on the stream.

You have specified:  "--merge-output-format mp4"

If the available codex for video or audio is not suitable for the mp4 
container, you are going to get an error.  For example, if a stream only has 
bestvideo in a VP9 codec at width 1280, and/or best audio in opus codec, this 
will barf if you try to merge it into a mp4 container without transcoding the 
video and/or audio streams using codecs compatible with mp4, instead of 
merging (copying) them into webm (mkv) as they come.

Hence it throws a wobbly back at you and asks you to run a search in case 
there is some URL with video/audio streams in codecs which will satisfy your 
mp4 container format requirement.

I don't think the single/double quote is an issue for Linux.  In MSWindows you 
ought to use double quotes.
