VRChat uses
web_embedded
in yt-dlp 2026.08.19 to play YouTube videos, however that's ongoing an A/B test at YouTube and may require PO tokens in the near future. This will break
web_embedded
as a guest visitor (the way VRChat uses yt-dlp).
Suggested action: Update to the latest yt-dlp version and use the
tv_samsung
extractor for format 18, to avoid the PO token requirement.
