/**
* SECTION:element-faac
* @seealso: faad
*
* faac encodes raw audio to AAC (MPEG-4 part 10) streams.
*
* The #GstFaac:outputformat property determines whether or not the
* AAC data needs additional framing provided by a container
* (such as Matroska or Quicktime).
* This is required for raw data, whereas ADTS formatted AAC already provides
* framing and needs no container.
*
* The #GstFaac:profile property determines the AAC profile, where the default
* Main profile is fine for most players and settings,
* but in some cases (e.g. hardware platforms)
* a more restricted profile/level may be necessary.
* In particular, typical (iTunes) m4a expects LC profile AAC data.
