Thanks for reading my question
I've googled enough to die, to find how to embed custom HTML5 Player on Facebook post. I've seen Youtube, Soundcloud, (and recently Sketchfab).. links when share on Facebook, it will be transformed into HTML5 player. I knew how to embed custom Flash player, but it's really hard to embed custom HTML5 player.
I've tried to use all OG tag they (Youtube, Sketchfab) used, I bought SSL certificate to have HTTPS url, ... but when share on Facebook, my link won't transform to HTML5 player...
Maybe only selected companies can use this feature?
Thanks a lot
