HTML5?
Is that the one that my HTML5-capable browser apparently doesn't do? The one where those twats have those hilariously jolly "dang poot" and "gosh snap" messages? How about instead of being such total nob-ends people put up a single static frame from the video with a simple informative message stating that the test for video capability didn't work?
And bbc and sky I'm looking at you here, having that message *not* almost entirely obscuring said possibly-representative frame, and along with everyone else, yes this does mean someone actually looks at what's in the video and making an editorial decision which for any news site I think is not a bad idea.
TLDR: possibly yay, when it works it's great, but when implemented by retards, not so much.
P.S. yes any excuse for an 'anti social media rant', noting free gift of multiple emphatic word grouping options there, not least because it's all completely evil and I normally never touch the stuff. And no, I absolutely make no claim to being suitably informed. It's the internet.
