<p>
cdiocddasrc reads and extracts raw audio from Audio CDs. It can operate
in one of two modes:
</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p>
treat each track as a separate stream, counting time from the start
of the track to the end of the track and posting EOS at the end of
a track, or
</p></li>
<li class="listitem"><p>
treat the entire disc as one stream, counting time from the start of
the first track to the end of the last track, posting EOS only at
the end of the last track.
</p></li>
</ul></div>
<p>
</p>
<p>
With a recent-enough version of libcdio, the element will extract
CD-TEXT if this is supported by the CD-drive and CD-TEXT information
is available on the CD. The information will be posted on the bus in
form of a tag message.
</p>
<p>
When opened, the element will also calculate a CDDB disc ID and a
MusicBrainz disc ID, which applications can use to query online
databases for artist/title information. These disc IDs will also be
posted on the bus as part of the tag messages.
</p>
<p>
cdiocddasrc supports the GstUriHandler interface, so applications can use
playbin with cdda://<track-number> URIs for playback (they will have
to connect to playbin's notify::source signal and set the device on the
cd source in the notify callback if they want to set the device property).
Applications should use seeks in "track" format to switch between different
tracks of the same CD (passing a new cdda:// URI to playbin involves opening
and closing the CD device, which is much slower).
</p>
<p>
</p>
<pre class="programlisting">
gst-launch-1.0 cdiocddasrc track=5 device=/dev/cdrom ! audioconvert ! vorbisenc ! oggmux ! filesink location=track5.ogg
</pre>
<p>
This pipeline extracts track 5 of the audio CD and encodes it into an
Ogg/Vorbis file.
