Well, I'm sure you can always find a level of abstraction where
everything is the same as everything else ;)

Ok, so you find appsrc too complicated for your special case where you
have the data in memory as one giant blob already. That's fair enough, I
wouldn't object to an element that makes this easier. Basically
something like the "dataurisrc" element without the URI diversion. Feel
free to file a feature request in bugzilla.

Cheers
