Hi thanks for awesome code,
I use fully updated Archlinux if i rollback to youtube-dl-2018.12.03-2-any.pkg.tar.xz then urls such as these will play but no longer with youtube-dl and mpv/cvlc

http://vidoza.net/fv3be6r2ctpt
https://vev.io/9jrj8m9jx8og
http://vidup.io/qdmy1jvgjmz9
https://streamplay.to/xvvq99m5y9sx

and many many more shown here https://ww1.watchseries-online.be/last-350-episodes
i am able to play those videos with 'mpv [URL]' subsequent versions of youtube-dl throw up

...

This happens on multiple sites which im guessing is either a bug or support has been dropped for all these domains at once.
For now my workaround is

warning: downgrading package youtube-dl (2018.12.09-1 => 2018.12.03-2)

and adding youtube-dl to pacman.conf IgnorePkg
i have not submitted bug report to archlinux as yet so
please advise if this is an arch packaging faux pas, or another PEBKAC
all URL's play in browser.
regards.

they all worked until recent update so i'm assuming support has been discontinued
thanks for explanation.
