| <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. |
