You should not get rid of the export profiles, but just hide them
based on the capabilities because someone should be able add a plugin
to enable them, and it will be inconvenient to make a package just for
more render profiles - both for packager and user. Is kdenlive already
doing some detection and hiding the ones for which the codec is not
available? I can add something to MLT to facilitate a query.

it should not be a lot of work. basically, something like:

$ inigo -consumer avformat f=list vcodec=list acodec=list

and the consumer will print a list of things on stderr similar to
ffmpeg, but probably different syntax.
