I was trying the Amara embed and tried some YouTube videos but for some reason they don't work and I don't get why?
Vimeo videos are working normally:
Thank you for reporting this, Ischa Gast,
I'm afraid I have messed up your https://codepen.io/IschaGast/pen/qoMwZX example: in order to see why the embed code was not working for https://www.youtube.com/watch?v=0iXYwWyM_E4, I used it in the https://amara.org/en/videos/create/ page, which should have opened the Amara page you tried to embed.
Instead it created https://amara.org/en/videos/DEWvkF8rTh10/info/flawless-css-ischa-gast/, which is a new page. And now that new Amara page for the YouTube video does play in your https://codepen.io/IschaGast/pen/qoMwZX page.
Sorry about that. Can you give me a new example of an Amara page that streams a YouTube video and that does not work when embedded?
