How to turn off video auto-play?

[Sapphireslinger]

So I open a tiddler and all the videos contained in it all start playing at once. AAaagh! Even the ones embedded in Detail widgets. Is there some "do-not-autoplay" code I am missing?

For instance: one of my tiddlers contains both of these codes:

<div class="container"><iframe src={{!!url}} 

frameborder="0" allowfullscreen class="video"></iframe></div>

and 

<$list filter="[<currentTiddler>tag[video]]"> <div class="container"><iframe src={{!!url}} frameborder="0" allowfullscreen class="video"></iframe></div> </$list>

The {{!!url}} just calls for a video file on my computer, the video is not actually in the tiddlywiki file.

Thanks in advance for any tips.

i’m not an expert on this but am using some local audio. i also use some details widgets but am gradually converting to streams. on ios, autoplay is not default, in contrast, for the same tw on other systems, only iframes that are intentionally not contained in details widgets or are in open substreams will auto play. not sure why mine is behaving differently to yours, it might be system/browser specific? i am also not using divs, just bare iframes, and have the url manually inserted e.g.
