Log file

There are m3u playlists that wont play in MPV. I end up having to read the m3u file manually then calling MPV again with --referrer to specify the referrer to make it work. Several video players support this feature so I wondered if MPV (my favorite video player) handles it and was surprised that it doesn't.

Hmm kodi uses a different method to pass a referrer. by adding |referer=https://example.com to the end so I guess its not a standard. could both ways be supported? Whats even stranger is that the curl option is referer with one R and so is yt-dlp's but others are also 2 r's if i remember correctly. who knows

hilarious, yet annoying at the same time garoto.

I concur, mpv should recognize http-referrer in EXTVLCOPT.
I noticed SMPlayer recognizes it and passes the option to mpv.
