By default we disallow the <embed> and <object> tags for security reasons. You can enable these tags if you trust all your users (or even just for a specific space / community) by going to admin console --> spaces --> settings --> filters and macros --> HTML. Edit the HTML filter and add 'embed' and 'object' to the list of allowed tags: 'Allowed HTML tag'.
Also, we have a bliptv and a youtube macro you can use:
As far as "trusting users", if we are limiting content development to
our own internal team (i.e. no outside developers at this time), I
assume the concern about security is limited, correct?
Thanks for the links as well.
Yeah, my comment about security was more geared to ClearspaceX where you have thousands of users; in an internal environment you'll lose your job if you tried to do something that monkeyed with other people's computers via an object / embed tag.
