Device::Cdio::Track - Class for track aspects of Device::Cdio.

    use Device::Cdio::Device;
    use Device::Cdio::Track;

    $device = Device::Cdio::Device->new(-source=>'/dev/cdrom');
    $track  = $device->get_last_track();
    print "track: %d, last lsn: %d\n", $track->{track}, track->get_last_lsn();

    $track = $device->get_first_track();
    $format = $rackt->get_format();

  new(device, track)->object

Creates a new track object.

  get_audio_channels(cdio, track)->int

Return number of channels in track: 2 or 4. Not meaningful if track is not an audio track. -1 is returned on error and -2 if the driver doesn't support the operation.

  get_copy_permit(cdio, track)->int

Return copy protection status on a track. Is this meaningful not an audio track?

  get_format()->$format

Get the format (e.g. 'audio', 'mode2', 'mode1') of track.

  get_last_lsn()->lsn

Return the ending LSN for a track $perlcdio::INVALID_LSN is returned on error.

  get_lba()->lba

Return the starting LBA for a track $perlcdio::INVALID_LBA is returned on error.

  get_lsn()->lsn

Return the starting LSN for a track $perlcdio::INVALID_LSN is returned on error.

  get_msf()

Return the starting MSF (minutes/secs/frames) for track number track. Track numbers usually start at something greater than 0, usually 1.

Returns string of the form mm:ss:ff if all good, or string 'error' on error.

  get_preemphasis()->result

Get linear preemphasis status on an audio track. This is not meaningful if not an audio track?

item get_track_sec_count()->int Get the number of sectors between this track an the next. This includes any pregap sectors before the start of the next track. Track numbers usually start at something greater than 0, usually 1.

$perlcdio::INVALID_LSN is returned on error.

  is_track_green(cdio, track) -> bool

Return True if we have XA data (green, mode2 form1) or XA data (green, mode2 form2). That is track begins:

  sync - header - subheader
  12     4      -  8

  set_track(track_num)

Set a new track number.

Device::Cdio is the top-level module, Device::Cdio::Device is a class device objects, and Device::Cdio::ISO9660 for working with ISO9660 systems.

perlcdio is the lower-level interface to libcdio.
