You could use decodebin2 and set the caps property to "audio/mpeg,parsed=true",
etc so it will continue to autoplug elements when there's some kind of parsed
output. But this requires to know all possible parsed caps and that the parsers
have a rank >= MARGINAL so it's not really a solution.

Another possibility would be to ask for specific elements if you know them by
name but that's a bit limited too ;)

And then you could write a "parsebin" that works like decodebin but stops when
the output is "parsed".


All this still has the problem that the current missing plugin messages don't
see a difference between decoders and parsers. So if you ask for
decoder-audio/mpeg,mpegversion=1 you could get a parser but you could also get
a decoder (which you don't want). So there should be a new message, etc for
parsers/demuxers too I guess... What do you think Tim?
