Device::Cdio::Track(3pm)
NAME
Device::Cdio::Track - Class for track aspects of Device::Cdio.
SYNOPSIS
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 = $rackt->get_format();
METHODS
- new
- new(device, track)->object
- Creates a new track object.
- get_audio_channels
- get_audio_channels(cdio, track)->int
- Return number of channels in track: 2 or 4. Not meaningful if track is
not an audio track. -1 is returned on error and -2 if the driver
doesn't support the operation. - get_copy_permit
- get_copy_permit(cdio, track)->int
- Return copy protection status on a track. Is this meaningful not an
audio track? - get_format
- get_format()->$format
- Get the format (e.g. 'audio', 'mode2', 'mode1') of track.
- get_last_lsn
- get_last_lsn()->lsn
- Return the ending LSN for a track $perlcdio::INVALID_LSN is returned on error.
- get_lba
- get_lba()->lba
- Return the starting LBA for a track $perlcdio::INVALID_LBA is returned on error.
- get_lsn
- get_lsn()->lsn
- Return the starting LSN for a track $perlcdio::INVALID_LSN is returned on error.
- get_msf
- 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
- get_preemphasis()->result
- Get linear preemphasis status on an audio track. This is not
meaningful if not an audio track? - get_track_sec_count
- 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
- 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
- set_track(track_num)
- Set a new track number.
