0. INTRODUCTION
============
Q. Who created abcde? Who develops it nowadays?
A. It was originally created by Robert Woodcook. He decided to give up
maintaining it at some point in 2002 and Jesus Climent took over. Contact
jesus.climent@hispalinux.es if you have a problem or a suggestion.
1. INSTALLATION
============
Q. How can I install abcde on my system?
A. To get abcde you can use a pre-packaged version, available for Debian,
FreeBSD, OpenBSD, NetBSD and others.
In case you want to install your own release, you need to download the
sources and install the complementary programs (abcde is just a frontend
and its functionality is provided by other programs).
Read
abcde needs cd-discid. Grab it from:
http://www.hispalinux.es/~data/files/cd-discid/
Read the README files for a complete list of requirements.
2. EXECUTION
=========
Q. Low on disk space?
A. abcde has different algorithms to schedule ripping and encoding - to
optimize for disk conservation, use -l. You can also define
WAVOUTPUTDIR=/some/other/path to your /etc/abcde.conf or ~/.abcde.conf to
store the WAV files on another NFS shared fisk, for example.
Q. How can i make abcde encode faster? My CD reader is way faster than the pace
it can encode my tracks.
A. abcde can take advantage of SMP systems, just like make. Try 'abcde -j 2' -
it'll run two encoder jobs while it rips the next track.
You can also make use of systems which are networked, with the help of
distmp3. For example, MachineA has a better CPU power and MachineB has a CD
drive. Run distmp3host (included in distmp3) on Machine A, and then run
abcde -r MachineA from MachineB (where "MachineA" is a dns name or IP
address). Use this in combination with '-j 0' to shift all encoding off the
local machine.
Q. I am having problems with *my CD reading program* reading the drive as a
user.
A. You might have to add yourself (or the users who want to use abcde) to the
cdrom group and change the permissions of the cdrom device to 660. If you
have a SCSI cdrom drive, check the permissions of /dev/sg* as well.
Q. I would like to give the trackname and the artist_name directly to the
encoder (in my case oggenc), but found no documentation.
A. That is not possible, since abcde gets the information from CDDB database.
You can create a template and fill it with the option "-n". Also, you can
get the CDDB entry and edit it yourself. abcde has also an option to drop
back to a template if you like none of the CDDB entries, selecting 0 from
the CDDB options.
Q. (Thanks to Amaya) Where are those options and settings defined? Why dont
you include a proper abcde.conf as an example?
A. I do. It should be installed under /etc/abcde.conf and contains more or
less all the defaults abcde uses. You can use $(HOME)/.abcde.conf to
override those defaults. More information can be obtained from the man page
which can be consulted using "man abcde".
Q. I keep on getting files with ".ogg.ogg" extension. What am I doing wrong?
A. The code for multiple-output adds automatically the extension of the
different outputs you select with the "-o" extension (or with OUTPUTTYPE
variable). Erase the ".${OUTPUTTYPE}" part from the OUTPUTFORMAT variable
in /etc/abcde.conf or ~/.abcde.conf
Q. I have modified some of the options, and now CDDB has stopped working.
A. Check that you have modified everything in the right way. For instance, if
you modify the HTTPGET program you might want to set some options of your
own. If you use the predefined ones (wget, curl and fetch) abcde will try
to use some defaults. Keep in mind that the output should go to the output
as standard output, to be saved in a file for later use.
If abcde seems to be ignoring your configuration options or not running
commands such as the encoder, you may have misquoted something. Config
options such as the following do not work:
LAMEOPTS=-h -k
Try this instead:
LAMEOPTS='-h -k'
Q. How can I separate the different output files I get using multiple-output
support?
A. Use the OUTPUT variable in PLAYLISTFORMAT and OUTPUTFORMAT. It holds the
different output file types you passed to abcde (i.e., ogg, mp3, flac)
during playlist creation and file/directory creation.
Q. I have a CD with a data track, and abcde complaints it cannot read/encode
it.
A. It is not easy to find a data track on a CD. Right now, I can only think
of getting the track info from CDDB and ask the user for continuing should
a "data" track name is found. But the solution is far from been optimal.
For now, if you find a "data" track and you know the number, restart abcde
specifying the tracks to be encoded, leaving out the data one.
Version 2.2 includes some checkings with cdparanoia, to try to get this
right.
Q. I am requested to have "eject" when setting the speed although I do not use
it for anything.
A. If you do not use cdparanoia, eject is used for setting the speed of the
cdrom drive. You can substitute it for "setcd" with "-x" as the argument,
but you have to install it manually (setcd is, at least, available in
Debian).
Another way to get the same results is using the pre_read function, defined
in your /etc/abcde.conf file.
Q. I have a CD set with 1+ discs, and want to have them in the same directory,
sorted properly. What can abcde do for me?
A. Set abcde to rip the first CD and give it the option "-t 101". Use a generic
name for the CD, and reuse it with the rest of the CDs, editing the CDDB
entries. Use "-t 201" for the second CD and so on. Use "-w <comment>" to
add a comment about the CD you are ripping (-w "disc #"). Alternatively you
can use only the "-t ###" option and then move all the files to the same
directory. If you want the tagged track number to be set to the modified
number you should use "-T ###". Even more! If you use "-W <cd_number>",
abcde will put a comment to every CD set ("CD <number>") and use modify the
number of the tracks.
Q. I have a live concert. I want to encode it in a single file. How do i do it?
A. Use "-1" and it will be encoded in a single file.
3. CDDB
====
Q. I need to go through an HTTP proxy for CDDB access.
A. No problem, just export your http_proxy variable first so wget/fetch/curl
can see it.
Q. I already store CDDB entries in my hard disc. Can I make use of them?
A. Piece of cake. Just edit CDDBLOCALDIR to point to the repository and give
abcde the "-L" flag to make use of it.
Q. Fine, now it uses local CDDB, but I have no network connection. How can I
disable CDDB checks?
A. Use the "-L -n" combination. It will try to use local CDDB entries, and if
nothing can be found, it will use a template. You will be also given the
choice to edit such template.
Q. How can I use some other CDDB information provider?
A. abcde now uses FreeDB by default. To use a different FreeDB mirror or
another CDDB service, change the CDDBURL option in your abcde.conf.
3. FORMATS
=======
Q. What formats can I encode my music to?
A. As for version 2.2, abcde includes support for MP3, Ogg/Vorbis,
Ogg/Speex, Flac and MPP/MP+(Musepack). Support for AAC will be added once
an FLOSS encoder/decoder is working.
Q. I want the new *put the newest and coolest codec there* format to be
supported by abcde. Abcde is so cool but i want to encode also to this
new format...
A. Patches are welcome! ;)
No, seriously, if the format is usable, available for Linux and open
source/free software, it should be fairly easy to integrate. Support for
AAC (m4p) should be the next one to be introduced.
Q. I use Debian/RedHat/(put your Unix flavour here) and MP3 encoding is not
working. What am I doing wrong?
A. Since MP3 is considered non-free (you get it for free, but hardware players
and net broadcasters have to pay license fees), some release engineering
groups and release management teams have decided not to provide MP3 encoding
tools.
These distributions or operative systems have decided to use Ogg/Vorbis as
the default encoding format, since it contains no (known) patent claims
and they are (supposed to be) completely Free (released under a BSD-like
license).
However, there is no strong (at the moment) hardware support, although
some groups and companies are strongly working on getting it, real soon
now. For that reason some people prefer to encode to MP3.
UPDATE *** UPDATE
There are at least 3 known brands already selling Ogg/Vorbis portable
players: Rio, iRiver and Neuros.
Go buy one and you have no more reasons to use MP3.
If you are among those individuals, you might need to add support for MP3
encoding to your system:
Debian : check http://marillat.free.fr to install lame in your system.
others prefer bladeenc. Check www.apt-get.org or google.
RedHat : search on rpmfind.net
FreeBSD: By default includes LAME support.
OpenBSD: Available by specifying you want to install the port with LAME
support, or by just installing it later from the ports tree.
NetBSD : Available in pkgsrc.
Others : Please, help me here.
Q. Huh! Why is MPPENCODER (with MPP) and .mpc the extension?
A. Dunno. You must ask the guys who created and defined the format. The
standard is MPEGplus (MPP/MP+) but the files use .mpc extension.
4. MISC PROBLEMS
==== ========
Q. What happened with normalize?
A. Normalize has changed its name under Debian, which is the GNU/Linux
distribution for developing abcde (well, is The GNU/Linux Distribution
i only use, at the moment). Now it is called normalize-audio.
If you are using some other flavour of OS, you need to change the name
of the executable in your abcde.conf file.
Q. I am using MacOSX and I am having problems to use abcde.
A. Well, I have a Mac, but I use linux on it. I have not been able to find
a way to make it work there, since I do not have the development tools
installed. I have placed a basic support, but some user reports are just
complaining about abcde not encoding the ripped tracks, as if
cdda2wav/cdparanoia/cddafs would never end reading them. If you have such
a system and experience problems, please, report them, and I will try to
work them out with your help.
Q. My hardware player (put it here) does not recognize the playlists created
with abcde. What I am doing wrong?
A. Try using "-m" when creating the playlists, or setting DOSPLAYLIST as an
option in the config file.
OBSOLETE
--------
Q. I set KEEPWAVS to "y" but abcde insists on erasing my directory, along
with the wav tracks. What I am doing wrong?
A. The default action set includes clean, which cleans the temp directory,
if nothing goes wrong. Take the "clean" out from the action list and you
are done.
UPDATE: KEEPWAVS unselects now the clean action.
