Right now I get the same as @Dr_Rek. However the 720p and 1080p versions actually start playing for a fraction of seconds, before hanging again.
It plays correctly on its own page.
It’s a general temporary problem: it’s also happening with the 2 clips in the first post at Uploads on videos.scanlines.xyz stuck at "video is being transcoded" which were playing without issues around 5 hours ago. It may be related to what’s being discussed there, whatever it turns out to be.
BTW thanks @cyberboy666 for trusting me with the admin rights. I haven’t got into the Peertube admin interface yet.
