I don't know how long this has been happening, but I tried viewing a YouTube video today in VLC & the resolution is always 640x360, even though the source video is available in 1080p on the YouTube website. I tried with a bunch of other 1080p video with the same result: VLC codec info shows 640x360 video resolution.
Did something change on YouTube's side that broke the youtube.lua script? Anyone else experiencing this?
