Exactly what I wrote: not your problem / premature optimization.

Scratch "uselessly" and you will get it right: -J gives you everything you
may need to download the video correctly. -g only gives you one piece of
information, which is sometimes sufficient (but not not enough that you do
not feel the need to call a second time for -e) but only for a few sites.

So here is the upside of -J: it works.

Second upside: it works with a single call.

Third upside: since the information is completely self-contained, you can
pass it around easily. People here whine about "ffmpeg -f youtubedl", and
they have valid arguments. This:

youtube-dl -J $url | ffmpeg -f youtubedl -i -

is just as easy, and nobody will whine.
