问题:

When I embed youtube on an HTTPS page using the iframe api in HTML5 mode , it still pulls the actual stream using HTTP, which generates a mixed content warning. Is this usecase properly supported?

I found this discussion from 2011 which suggests it wasn't. However I just tried accessing the CDN server using HTTPS and it works - kind of - but it returns the wrong certificate (google.com instead of something for youtube.com).

Has anyone managed to embed a video on a HTTPS page using the IFRAME API in HTML5 without triggering a mixed content warning (ie. the lock with the yellow warning sign in Chrome)?

Thanks

It seems that (as of October 2012) this is the expected behaviour and there are no plans to change it: https://code.google.com/p/gdata-issues/issues/detail?id=2964&can=1&q=youtube%20https&colspec=API%20ID%20Type%20Status%20Priority%20Stars%20Summary

You can fix this by configuring your iframe API script to look like this.

Use '//' for the tag src

var tag = document.createElement('script');
tag.src = "//www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
var url = window.location.pathname;

This will cause the player to load the resources using the same protocol as the page it is embedded on.
