How can I add a remote resource link to the OPF manifest of an epub3?
This is the background of my question:
I would like to embed some videos without including the large video files in the epub. The videos are 'extra contents', not really the core of my publication, so if readers/watchers don't have an internet connection, it's not a catastrophe. This is easily done with the 'Smart Object' and works well when I export the publication as an iOS app. For an epub you'll also have to set the OPF Properties of the page that embeds the video to 'remote-resources', which is also easily done in Pubcoder. Yet, the links to the resources need also be included in the OPF manifest. I don't see how I can edit or otherwise change the manifest in Pubcoder. But maybe I overlook something.
Any help is greatly appreciated.
Kind regards,
Bram
