Here
gst-inspect-1.0 mp4mux
shows:
SINK template: 'audio_%u'
Availability: On request
Capabilities:
...
audio/mpeg
mpegversion: 4
stream-format: raw
channels: [ 1, 8 ]
rate: [ 1, 2147483647 ]
There is also a plugin for fdk-aac in gst-plugins-bad, but it looks
like it's not shipped by the debian packages at the moment.
Since this is a request pad you may have to create it (request it) in
your application explicitly.
Cheers
Tim
