It gives me exactly the same message but I’m not using a VPN. When I use the external viewer option with mpv using yt-dlp I only get video without audio. I can download the video fine using yt-dlp and then watch it with mpv, but if I try to stream to mpv while downloading to watch it real-time it gives an ffmpeg error: can’t recognize format… weird.

Here you have all the packages you can install for specific purposes grouped by categories

Use yt-dlp URL -o - | mpv - This way the video goes directly to mpv without using the disk, avoiding the need to delete. It should work with other viewers as well.
