<p>
faac encodes raw audio to AAC (MPEG-4 part 3) streams.
</p>
<p>
The <a class="link" href="gst-plugins-bad-plugins-faac.html#GstFaac--outputformat" title='The "outputformat" property'><span class="type">"outputformat"</span></a> 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.
</p>
<p>
The <a class="link" href="gst-plugins-bad-plugins-faac.html#GstFaac--profile" title='The "profile" property'><span class="type">"profile"</span></a> property determines the AAC profile, where the default
LC (Low Complexity) profile is most widely used, supported and suitable for
general use. The other profiles are very rarely used and often not supported.
