decoderbin:
A bin with a sinkpad that decodes the data into raw formats. It works by sending
the input data through a typefind element and then recursively autoplugs elements
from the registry until a raw format is obtained. It will then create a new ghostpad
on itself to signal the app of the new pad.
Decodebin will also remove pads when they are removed from the stream.

A bin with an uri property. It will find the right source element from the registry
and connect a decoderbin to it. When going to the PAUSED state, it will iterate the
decoderbin and listen for new pad signals from it. It will connect a queue to each
new pad and will iterate the decoderbin until one of the queues is filled. It is
assumed that by that time all the streams will be found so that when leaving the
PAUSED state, one can query the number of streams in the media file with the given
uri.
Playbasebin internally groups related streams together in a GstPlayBaseGroup. This
is particulary important for chained oggs. Initially, a new group is created in
the 'building' state. All new streams will be added to the building group until
no-more-pads is signaled or one of the preroll queues overflows. When this happens,
the group is commited to a list of groups ready for playback. PlaybaseBin will then
attach a padprobe to each stream to figure out when it finished. It will remove
the current group and install the next playable group, then.

Before going to the PLAYING state, it is possible to connect a custom element to
each of the streams. To do that, you have to add the element to the bin and then
connect the pad(s) from the stream(s). You do not have to add the elements in
a thread, the bin will take care of then when it's needed. You are allowed to use
threads inside the elements, of course.
The bin tries to be smart and doesn't add a queue when there is only one possible
stream.
