Some discussoin down at #gstreamer:

<slomo> kov: you need a MIME type <-> caps conversion and then you could check
the registry
<slomo> or what everybody else said before ;)
<bilboed-pi> even then, it's not guaranteed
<__tim> we should add an FAQ entry for this somewhere ;)
<kov> __tim, I did look for that in the FAQ ;D
<bilboed-pi> i.e. MIME-TYPE : video/x-asf => neat, I have an asfdemux, all good
=> but you fail because you don't have the decoders
<ensonic> yes, if you don't find elements, then it won't play, but the opposite
doe not have to be tru automatically
<kov> bilboed-pi, right, but I may also have the codec names
 does that help somehow?
 such as: type: video/ogg, codec: speex
 sorry, audio/ogg, speex
<bilboed-pi> you'd have to do a mapping table
 between your application's type system and gstreamer caps
<kov> bilboed-pi, sounds like a plan
<bilboed-pi> there are corner cases where it will fail though... because that
codec description isn't verbose enough
<kov> I have made a quick try to see if I could get the tests working:
https://bugs.webkit.org/attachment.cgi?id=39836&action=review
 I guess I'll have to play with that quite a bit more =)
<bilboed-pi> mp3 => audio/mpeg, mpegversion=1, layer=3
 wav is tricky
 it's a container format
 which, agreed, is mostly used for raw pcm... but can contain mp3 or other
codecs
<kov> I guess we can handle corner cases as we find them
 if we get 80% coverage I'll be happy
