Depending on your audience, including content that requires an Internet connection may not be the best way to create an EPUB. Many EPUB readers are used without an Internet connection.
If the Vimeo website lets you choose an Embed option (I've never visited it), then you could use InDesign's Object > Insert HTML feature. This will only work in Fixed Layout EPUB, created by InDesign CC 2014.
Thank you Steve.
Yeh, this an option.
Although... you want to tell me that there is no way to link a Youtube or Vimeo online movie into an epub book?!
If I need 20 videos inside, embedding them will make it very heavy. This is why streaming them is a good option. Although, they are not on a Flash Server.
I believe that YouTube provides an HTML embed code. Are you saying Video is Flash-only and doesn't provide HTML video through an embed code? How could they be viewed on non-Flash devices like almost all tablets?
