Some of my feeds have Vine videos embedded. I have noticed that on the iPad, they autoplay. What’s weird is that sometimes the video that is autoplaying won’t even be on the feed entry that I’m looking at. It might be the next entry or a previous one.
Other embedded videos don’t seem to do this, just Vine.
It’s what the publisher wants, unfortunately. I could possibly disable it, but the publisher is specifically asking for it to auto play, and I often respect the publisher’s intention.
That one is not a Vine, though…it looks like they have an iFrame’d video, but it autoplays an ad if you wait on the screen for a few moments. On an iPhone, the video goes fullscreen!
