Again, thats exactly the plan. We should have:
  - create a source media description (basically a list of pads), also
have a utility function here to create that from
   an existing pipeline (take all unconnected src pads) - that can be
used for transcoding
  - a way to enumerate possible output formats for a source media
description (like if source is audio+video, don't offer wav)
  - a way to create an encodebin from a output-fomat profile
  - a utility function to connect the source-media to the encode-bin
  - among other things a dialog that given a source media description,
with let the user choose a output-format profile and return that

If we can agree that list of pads is good for source media description,
we need to figure what we can use for the target format description.
Imho this is like the device profiles that Uraeus described on the wiki.
