Try static version:
For example:
Code
wget https://yt-dl.org/downloads/latest/youtube-dl -O /storage/bin/youtube-dl
chmod a+rx /storage/bin/youtube-dl
# Sky News live
/storage/bin/youtube-dl -f 91 "https://www.youtube.com/watch?v=lrX6ktLg8WQ" -g
or
/storage/bin/youtube-dl -f best "https://www.youtube.com/watch?v=lrX6ktLg8WQ" -g
It works for me (Raspberry 3b+, Libreelec 9.0.1, HTS Tvheadend 4.3-1774).
