Precache the next entry in your playlist if it is a network source by downloading it to a temp file ahead of time. Change Line 20 to temp directory. It will delete the directory on exit.
----------------------
-- #example ytdl_preload.conf
-- # make sure lines do not have trailing whitespace
-- # ytdl_opt has no sanity check and should be formatted exactly how it would appear in yt-dlp CLI, they are split into a key/value pair on whitespace
-- # at least on Windows, do not escape '\' in temp, just us a single one for each divider
-- #temp=R:\ytdltest
-- #ytdl_opt1=-r 50k
-- #ytdl_opt2=-N 5
