<a name="gst-plugins-good-plugins-aacparse.description"></a><h2>Description</h2>
<p>
This is an AAC parser which handles both ADIF and ADTS stream formats.
</p>
<p>
As ADIF format is not framed, it is not seekable and stream duration cannot
be determined either. However, ADTS format AAC clips can be seeked, and parser
can also estimate playback position and clip duration.
