Interactive video on Canvas

Hi

I've been trying to create an interactive video on the Canvas platform following the given guidelines. Everything seems to work except that the content is not displayed. I wrote to the support of Canvas thinking that this was due to the set up, but I got partly the following answer regarding the SSL-sertificate of h5p.org:

"The reason your video does not work is due to the fact that the URl your using does not start with "https://". Most browsers block http:// content on https:// pages (so-called mixed content). Canvas runs https:// but the URL of your interactive video (http://h5p.org/...) does not. 

Further, he wrote:

"I see that you cannot use a link from h5p.org since their web server appears to be wrongly configurated  for https:// as it presents an SSL certificate which does not fit the host name h5p.org."

So, how can this be solved? I really would like to use the interactive videos as part of a MOOC course this fall.
