I don’t think the stream, per se, was the problem with the Nick Cave concert last night. It’s was a Vimeo embed, they know how to stream and devices optimise for video. It’s the page around it that @dicefm needs to fix.
Trying to reload the video’s page on my iPad Pro last night, the browser had crashed. This suggests to me that it was the tracking and social overlays on the page embedding the video that was causing the problems.
Once I switched to my laptop, a typical web developer’s high powered machine, the streaming was perfect. Of course, by then I’d missed the first third of the concert.
As long as the tracking and social overlays remain on the page, it’s likely the show will only be viewable on powerful computers. With fewer viewers on the page at any one time it’s possible a less powerful device might work but really, that’s a roll of the dice.
The real irony of all the social crap on the page is that it’s invisible the moment a user sends the video full screen.
