Tommi, decodebin2 can do exactly what you're asking for... In fact it was
designed partly to support EXACTLY what you want to do (hint:n770).

What you need to do is to tell decodebin2 what formats you can handle out=
side
of it.

Let's say, for example, you can handle "audio/mpeg,mpegversion=3D1,layer=3D=
[1,3]"
with a dedicated sink. The easiest way is to add that caps to the 'caps'
property of decodebin2.
By default 'caps' contains all know raw audio/video/text formats, so you =
need
to create a new caps containing those PLUS your format:

mycaps =3D
gst_caps_from_string("video/x-raw-yuv;video/x-.....plain;text/x-pango-mar=
kup;audio/mpeg,mpegversion=3D1,layer=3D[1,3]");
g_object_set (mydecodebin2, "caps", mycaps, NULL);

decodebin2 will then consider mp3 as a final format and will provide you =
that
pad like any other raw stream (using 'new-decoded-pad' callback). Then yo=
u can
connect it to your dedicated sink.


On the other hand, playbin HAS to be modified to support what you request=
. In
the same way decodebin2 was created from scratch, there is a new playbin
(playbin2) currently being designed which will use all the advantages
decodebin2 brings and be able to handle the features you mention.

Changing the bug title accordingly.
