Integration with Chinese video sites (Youku, Tudou)
As you know, Youtube is not accessible from Mainland China, so it would be easier for Chinese users to have the local videos sites integration in Eliademy, such as Youku.com(优酷网), Tudou.com(土豆网).
Currently, we only can use the iFrame button to embed videos, but it’s too complicate for a normal user to extract html code and also complicate for viewers to change the Firegox or Chrome safety settings every time when view a course.
Support is Tudou is requested from oEmbed development community, which can be tracked here https://github.com/starfishmod/jquery-oembed-all/issues/98.
I come from Mainland China,in my opinion ,you can use Vimeo video.
