mpv freetube ytdl-raw-options "Custom External Player Arguments" on Windows

[KamelittaOida]

i'm writing cause it took me quite a while to figure this out, even though it's an external player issue i.e. not necessarily related to freetube like mentioned here #3820 (comment)

i received the IP thing today [Bug]: Error: [BAD_HTTP_STATUS: 403] Potential causes: IP block or streaming URL deciphering failed

if you need "Custom External Player Arguments" you need to use --ytdl-raw-options=, arguments with --ytdl-format= do not work.
e.g. --ytdl-raw-options=format="(best[height<=400]/bestvideo+bestaudio)"

mpv ytdl-raw-options= ; ytdl-raw-options ; ytdl-format ; ytdl-format=
