When something is shared from youtube to facebook, facebook is now showing the youtube html5 player.
If you look up one of their urls (https://www.youtube.com/watch?v=uuS5ZyQhvsk) in the open graph debugger you can see that they are now providing open graph meta data for their html player as well as the flash one.
I also have a player that sits in an iframe, and am now including the same tags that youtube is, minus the flash ones as we don't have a flash player, but it isn't working and facebook is giving me this error which doesn't make sense:
Share has playable media but will not play inline because it would cause a mixed content warning if embedded. Add a secure_src or make the video src secure to fix this.
This is the information facebook is reading:
This is the url as an example that is generating that error: https://www.la1tv.co.uk/player/124/260
All I can think is that Facebook has made some kind of deal with youtube and this isn't available for everyone yet, but that isn't clear from that error.
All of the content on our site is served over https.
Anyone know what's going on or got this working?
I can't find any documentation anywhere on facebook how to do this.
I posted a similar question a while back when I was trying to get this working but at this time youtube was still only providing the flash player to facebook.
It looks like someone else was having a similar issue here.
