To explain more in detail how I did this, using git master Transmageddon I
loaded the gravity.mpg file from :
http://gstreamer.freedesktop.org/media/large/gravity.mpg

I then choose the 'no container option' which disables video (I am trying to
create a pure audio file here) and choose AAC. Once I press transcode the
pipeline halts. If I try mp3 or FLAC it works as expected.

Ishould be quite clear from the PNG as you see the capsfilter behind the
aacparser tries to set stream format to ADTS, but in front of the accparser
this information doesn't reach and thus is defaults to raw
 in order words faac doesn't get told to ouput ADTS instead of raw due to the
message being 'blocked' by the aacparser
