All source code in the src directory is covered under the
|
||||
GNU General Public License (GNU GPL).
|
||||
|
||||
|
||||
|
||||
GNU GENERAL PUBLIC LICENSE
|
||||
Version 2, June 1991
|
||||
|
||||
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
|
||||
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
Preamble
|
||||
|
||||
The licenses for most software are designed to take away your
|
||||
freedom to share and change it. By contrast, the GNU General Public
|
||||
License is intended to guarantee your freedom to share and change free
|
||||
software--to make sure the software is free for all its users. This
|
||||
General Public License applies to most of the Free Software
|
||||
Foundation's software and to any other program whose authors commit to
|
||||
using it. (Some other Free Software Foundation software is covered by
|
||||
the GNU Library General Public License instead.) You can apply it to
|
||||
your programs, too.
|
||||
|
||||
When we speak of free software, we are referring to freedom, not
|
||||
price. Our General Public Licenses are designed to make sure that you
|
||||
have the freedom to distribute copies of free software (and charge for
|
||||
this service if you wish), that you receive source code or can get it
|
||||
if you want it, that you can change the software or use pieces of it
|
||||
in new free programs; and that you know you can do these things.
|
||||
|
||||
To protect your rights, we need to make restrictions that forbid
|
||||
anyone to deny you these rights or to ask you to surrender the rights.
|
||||
These restrictions translate to certain responsibilities for you if you
|
||||
distribute copies of the software, or if you modify it.
|
||||
|
||||
For example, if you distribute copies of such a program, whether
|
||||
gratis or for a fee, you must give the recipients all the rights that
|
||||
you have. You must make sure that they, too, receive or can get the
|
||||
source code. And you must show them these terms so they know their
|
||||
rights.
|
||||
|
||||
We protect your rights with two steps: (1) copyright the software, and
|
||||
(2) offer you this license which gives you legal permission to copy,
|
||||
distribute and/or modify the software.
|
||||
|
||||
Also, for each author's protection and ours, we want to make certain
|
||||
that everyone understands that there is no warranty for this free
|
||||
software. If the software is modified by someone else and passed on, we
|
||||
want its recipients to know that what they have is not the original, so
|
||||
that any problems introduced by others will not reflect on the original
|
||||
authors' reputations.
|
||||
|
||||
Finally, any free program is threatened constantly by software
|
||||
patents. We wish to avoid the danger that redistributors of a free
|
||||
program will individually obtain patent licenses, in effect making the
|
||||
program proprietary. To prevent this, we have made it clear that any
|
||||
patent must be licensed for everyone's free use or not licensed at all.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.
|
||||
|
||||
GNU GENERAL PUBLIC LICENSE
|
||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||
|
||||
0. This License applies to any program or other work which contains
|
||||
a notice placed by the copyright holder saying it may be distributed
|
||||
under the terms of this General Public License. The "Program", below,
|
||||
refers to any such program or work, and a "work based on the Program"
|
||||
means either the Program or any derivative work under copyright law:
|
||||
that is to say, a work containing the Program or a portion of it,
|
||||
either verbatim or with modifications and/or translated into another
|
||||
language. (Hereinafter, translation is included without limitation in
|
||||
the term "modification".) Each licensee is addressed as "you".
|
||||
|
||||
Activities other than copying, distribution and modification are not
|
||||
covered by this License; they are outside its scope. The act of
|
||||
running the Program is not restricted, and the output from the Program
|
||||
is covered only if its contents constitute a work based on the
|
||||
Program (independent of having been made by running the Program).
|
||||
Whether that is true depends on what the Program does.
|
||||
|
||||
1. You may copy and distribute verbatim copies of the Program's
|
||||
source code as you receive it, in any medium, provided that you
|
||||
conspicuously and appropriately publish on each copy an appropriate
|
||||
copyright notice and disclaimer of warranty; keep intact all the
|
||||
notices that refer to this License and to the absence of any warranty;
|
||||
and give any other recipients of the Program a copy of this License
|
||||
along with the Program.
|
||||
|
||||
You may charge a fee for the physical act of transferring a copy, and
|
||||
you may at your option offer warranty protection in exchange for a fee.
|
||||
|
||||
2. You may modify your copy or copies of the Program or any portion
|
||||
of it, thus forming a work based on the Program, and copy and
|
||||
distribute such modifications or work under the terms of Section 1
|
||||
above, provided that you also meet all of these conditions:
|
||||
|
||||
a) You must cause the modified files to carry prominent notices
|
||||
stating that you changed the files and the date of any change.
|
||||
|
||||
b) You must cause any work that you distribute or publish, that in
|
||||
whole or in part contains or is derived from the Program or any
|
||||
part thereof, to be licensed as a whole at no charge to all third
|
||||
parties under the terms of this License.
|
||||
|
||||
c) If the modified program normally reads commands interactively
|
||||
when run, you must cause it, when started running for such
|
||||
interactive use in the most ordinary way, to print or display an
|
||||
announcement including an appropriate copyright notice and a
|
||||
notice that there is no warranty (or else, saying that you provide
|
||||
a warranty) and that users may redistribute the program under
|
||||
these conditions, and telling the user how to view a copy of this
|
||||
License. (Exception: if the Program itself is interactive but
|
||||
does not normally print such an announcement, your work based on
|
||||
the Program is not required to print an announcement.)
|
||||
|
||||
These requirements apply to the modified work as a whole. If
|
||||
identifiable sections of that work are not derived from the Program,
|
||||
and can be reasonably considered independent and separate works in
|
||||
themselves, then this License, and its terms, do not apply to those
|
||||
sections when you distribute them as separate works. But when you
|
||||
distribute the same sections as part of a whole which is a work based
|
||||
on the Program, the distribution of the whole must be on the terms of
|
||||
this License, whose permissions for other licensees extend to the
|
||||
entire whole, and thus to each and every part regardless of who wrote it.
|
||||
|
||||
Thus, it is not the intent of this section to claim rights or contest
|
||||
your rights to work written entirely by you; rather, the intent is to
|
||||
exercise the right to control the distribution of derivative or
|
||||
collective works based on the Program.
|
||||
|
||||
In addition, mere aggregation of another work not based on the Program
|
||||
with the Program (or with a work based on the Program) on a volume of
|
||||
a storage or distribution medium does not bring the other work under
|
||||
the scope of this License.
|
||||
|
||||
3. You may copy and distribute the Program (or a work based on it,
|
||||
under Section 2) in object code or executable form under the terms of
|
||||
Sections 1 and 2 above provided that you also do one of the following:
|
||||
|
||||
a) Accompany it with the complete corresponding machine-readable
|
||||
source code, which must be distributed under the terms of Sections
|
||||
1 and 2 above on a medium customarily used for software interchange; or,
|
||||
|
||||
b) Accompany it with a written offer, valid for at least three
|
||||
years, to give any third party, for a charge no more than your
|
||||
cost of physically performing source distribution, a complete
|
||||
machine-readable copy of the corresponding source code, to be
|
||||
distributed under the terms of Sections 1 and 2 above on a medium
|
||||
customarily used for software interchange; or,
|
||||
|
||||
c) Accompany it with the information you received as to the offer
|
||||
to distribute corresponding source code. (This alternative is
|
||||
allowed only for noncommercial distribution and only if you
|
||||
received the program in object code or executable form with such
|
||||
an offer, in accord with Subsection b above.)
|
||||
|
||||
The source code for a work means the preferred form of the work for
|
||||
making modifications to it. For an executable work, complete source
|
||||
code means all the source code for all modules it contains, plus any
|
||||
associated interface definition files, plus the scripts used to
|
||||
control compilation and installation of the executable. However, as a
|
||||
special exception, the source code distributed need not include
|
||||
anything that is normally distributed (in either source or binary
|
||||
form) with the major components (compiler, kernel, and so on) of the
|
||||
operating system on which the executable runs, unless that component
|
||||
itself accompanies the executable.
|
||||
|
||||
If distribution of executable or object code is made by offering
|
||||
access to copy from a designated place, then offering equivalent
|
||||
access to copy the source code from the same place counts as
|
||||
distribution of the source code, even though third parties are not
|
||||
compelled to copy the source along with the object code.
|
||||
|
||||
4. You may not copy, modify, sublicense, or distribute the Program
|
||||
except as expressly provided under this License. Any attempt
|
||||
otherwise to copy, modify, sublicense or distribute the Program is
|
||||
void, and will automatically terminate your rights under this License.
|
||||
However, parties who have received copies, or rights, from you under
|
||||
this License will not have their licenses terminated so long as such
|
||||
parties remain in full compliance.
|
||||
|
||||
5. You are not required to accept this License, since you have not
|
||||
signed it. However, nothing else grants you permission to modify or
|
||||
distribute the Program or its derivative works. These actions are
|
||||
prohibited by law if you do not accept this License. Therefore, by
|
||||
modifying or distributing the Program (or any work based on the
|
||||
Program), you indicate your acceptance of this License to do so, and
|
||||
all its terms and conditions for copying, distributing or modifying
|
||||
the Program or works based on it.
|
||||
|
||||
6. Each time you redistribute the Program (or any work based on the
|
||||
Program), the recipient automatically receives a license from the
|
||||
original licensor to copy, distribute or modify the Program subject to
|
||||
these terms and conditions. You may not impose any further
|
||||
restrictions on the recipients' exercise of the rights granted herein.
|
||||
You are not responsible for enforcing compliance by third parties to
|
||||
this License.
|
||||
|
||||
7. If, as a consequence of a court judgment or allegation of patent
|
||||
infringement or for any other reason (not limited to patent issues),
|
||||
conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot
|
||||
distribute so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you
|
||||
may not distribute the Program at all. For example, if a patent
|
||||
license would not permit royalty-free redistribution of the Program by
|
||||
all those who receive copies directly or indirectly through you, then
|
||||
the only way you could satisfy both it and this License would be to
|
||||
refrain entirely from distribution of the Program.
|
||||
|
||||
If any portion of this section is held invalid or unenforceable under
|
||||
any particular circumstance, the balance of the section is intended to
|
||||
apply and the section as a whole is intended to apply in other
|
||||
circumstances.
|
||||
|
||||
It is not the purpose of this section to induce you to infringe any
|
||||
patents or other property right claims or to contest validity of any
|
||||
such claims; this section has the sole purpose of protecting the
|
||||
integrity of the free software distribution system, which is
|
||||
implemented by public license practices. Many people have made
|
||||
generous contributions to the wide range of software distributed
|
||||
through that system in reliance on consistent application of that
|
||||
system; it is up to the author/donor to decide if he or she is willing
|
||||
to distribute software through any other system and a licensee cannot
|
||||
impose that choice.
|
||||
|
||||
This section is intended to make thoroughly clear what is believed to
|
||||
be a consequence of the rest of this License.
|
||||
|
||||
8. If the distribution and/or use of the Program is restricted in
|
||||
certain countries either by patents or by copyrighted interfaces, the
|
||||
original copyright holder who places the Program under this License
|
||||
may add an explicit geographical distribution limitation excluding
|
||||
those countries, so that distribution is permitted only in or among
|
||||
countries not thus excluded. In such case, this License incorporates
|
||||
the limitation as if written in the body of this License.
|
||||
|
||||
9. The Free Software Foundation may publish revised and/or new versions
|
||||
of the General Public License from time to time. Such new versions will
|
||||
be similar in spirit to the present version, but may differ in detail to
|
||||
address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the Program
|
||||
specifies a version number of this License which applies to it and "any
|
||||
later version", you have the option of following the terms and conditions
|
||||
either of that version or of any later version published by the Free
|
||||
Software Foundation. If the Program does not specify a version number of
|
||||
this License, you may choose any version ever published by the Free Software
|
||||
Foundation.
|
||||
|
||||
10. If you wish to incorporate parts of the Program into other free
|
||||
programs whose distribution conditions are different, write to the author
|
||||
to ask for permission. For software which is copyrighted by the Free
|
||||
Software Foundation, write to the Free Software Foundation; we sometimes
|
||||
make exceptions for this. Our decision will be guided by the two goals
|
||||
of preserving the free status of all derivatives of our free software and
|
||||
of promoting the sharing and reuse of software generally.
|
||||
|
||||
NO WARRANTY
|
||||
|
||||
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
|
||||
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
|
||||
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
|
||||
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
|
||||
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
|
||||
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
|
||||
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
|
||||
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
|
||||
REPAIR OR CORRECTION.
|
||||
|
||||
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
|
||||
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
|
||||
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
|
||||
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
|
||||
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
|
||||
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
|
||||
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
|
||||
POSSIBILITY OF SUCH DAMAGES.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
How to Apply These Terms to Your New Programs
|
||||
|
||||
If you develop a new program, and you want it to be of the greatest
|
||||
possible use to the public, the best way to achieve this is to make it
|
||||
free software which everyone can redistribute and change under these terms.
|
||||
|
||||
To do so, attach the following notices to the program. It is safest
|
||||
to attach them to the start of each source file to most effectively
|
||||
convey the exclusion of warranty; and each file should have at least
|
||||
the "copyright" line and a pointer to where the full notice is found.
|
||||
|
||||
<one line to give the program's name and a brief idea of what it does.>
|
||||
Copyright (C) <year> <name of author>
|
||||
|
||||
This program is free software; you can redistribute it and/or modify
|
||||
it under the terms of the GNU General Public License as published by
|
||||
the Free Software Foundation; either version 2 of the License, or
|
||||
(at your option) any later version.
|
||||
|
||||
This program is distributed in the hope that it will be useful,
|
||||
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
|
||||
GNU General Public License for more details.
|
||||
|
||||
You should have received a copy of the GNU General Public License
|
||||
along with this program; if not, write to the Free Software
|
||||
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
|
||||
|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
If the program is interactive, make it output a short notice like this
|
||||
when it starts in an interactive mode:
|
||||
|
||||
Gnomovision version 69, Copyright (C) year name of author
|
||||
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
||||
This is free software, and you are welcome to redistribute it
|
||||
under certain conditions; type `show c' for details.
|
||||
|
||||
The hypothetical commands `show w' and `show c' should show the appropriate
|
||||
parts of the General Public License. Of course, the commands you use may
|
||||
be called something other than `show w' and `show c'; they could even be
|
||||
mouse-clicks or menu items--whatever suits your program.
|
||||
|
||||
You should also get your employer (if you work as a programmer) or your
|
||||
school, if any, to sign a "copyright disclaimer" for the program, if
|
||||
necessary. Here is a sample; alter the names:
|
||||
|
||||
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
|
||||
`Gnomovision' (which makes passes at compilers) written by James Hacker.

||||
|
||||
This General Public License does not permit incorporating your program into
|
||||
proprietary programs. If your program is a subroutine library, you may
|
||||
consider it more useful to permit linking proprietary applications with the
|
||||
library. If this is what you want to do, use the GNU Library General
|
||||
Public License instead of this License.

DarkIce Frequenty Asked Questions
|
||||
|
||||
|
||||
Q: I get the following error:
|
||||
|
||||
DarkIce: LameLibEncoder.cpp:75: lame lib opening underlying sink error [0]
|
||||
|
||||
What am I doing wrong?
|
||||
|
||||
|
||||
A: This error means (quite anti-intuitively), that darkice coulnd't connect
|
||||
to the streaming server. Please double-check the following values in
|
||||
your config file:
|
||||
- server
|
||||
- port
|
||||
- password
|
||||
|
||||
If you're streaming to a shoutcast server, make sure that the port
|
||||
you use is the _source_ port, which is usually 1 above the _client_
|
||||
port for shoutcast (the defaults are 8000 for client, 8001 for source).

DarkIce installation notes
|
||||
==========================
|
||||
|
||||
DarkIce uses the following libraries (and associated header files):
|
||||
|
||||
for capability to stream mp3 to IceCast 1.x and Shoutcast:
|
||||
- libmp3lame
|
||||
|
||||
for capability to stream Ogg Vorbis to IceCast 2:
|
||||
- libogg
|
||||
- libvoribs
|
||||
- libvorbisenc
|
||||
|
||||
To install libmp3lame, please refer to INSTALL.lame.
|
||||
To install libogg, libvoribs and libvorbisenc, please look at INSTALL.vorbis.
|
||||
|
||||
|
||||
Installing DarkIce
|
||||
------------------
|
||||
|
||||
If you're reading this, you probably have downloaded and extracted the
|
||||
DarkIce tarball. Go to the directory you extracted it, and try:
|
||||
|
||||
./configure --help
|
||||
|
||||
This will give you all the compile configuration options.
|
||||
|
||||
On Solaris systems, for some reason the configure script does not
|
||||
find the include file lame/lame.h if it uses the SUN Workshop C compiler
|
||||
as a preprocessor for testing. Therefore you might consider setting:
|
||||
|
||||
export CPP="gcc -E"
|
||||
|
||||
This hack is not needed on other systems.
|
||||
|
||||
If chosing the default compile options, issue the following commands:
|
||||
|
||||
./configure
|
||||
make
|
||||
make install
|
||||
|
||||
For the last step, you need to be root or have write permissions in the
|
||||
target directories, usually directories under /usr/local.
|
||||
|
||||
Now you should have DarkIce installed. For documentation, try
|
||||
|
||||
man darkice
|
||||
|
||||
To try out the program, try
|
||||
|
||||
darkice -h
|

||||
|

|
|||
Installing Lame
|
||||
---------------
|
||||
|
||||
To install DarkIce, you need the Lame 3.89 or later libraries and
|
||||
related header files already installed on your system.
|
||||
|
||||
It is recommended that use install Lame to the usual system locations,
|
||||
/usr/lib, /usr/include, so that DarkIce will find the header files and
|
||||
libraries. Thus when configuring, add --prefix=/usr to the configure
|
||||
options.
|
||||
|
||||
Grab the latest lame source tarball from a download site found at
|
||||
http://www.mp3dev.org/mp3/download/download.html
|
||||
or from the DarkIce SourceForge project download area
|
||||
http://sourceforge.net/project/showfiles.php?group_id=14111
|
||||
|
||||
I took lame lame-3.91.tar.gz. Go to the directory where you saved it,
|
||||
and issue the following commands:
|
||||
|
||||
tar xfz lame-3.91.tar.gz
|
||||
cd lame-3.91
|
||||
./configure --with-fileio=lame --without-vorbis --disable-gtktest --enable-expopt=full --prefix=/usr
|
||||
make
|
||||
make install
|
||||
|
||||
For the last step, you need to be root or have write permissions in the
|
||||
target directories.
|
||||
|
||||
You might consider using nasm if you're on a i386 system, with the
|
||||
configure option --enable-nasmm, for maximum performance.
|
||||
|
||||
|
||||
On RedHat Linux
|
||||
---------------
|
||||
|
||||
Compiling Lame on RedHat Linux is a tricky issue, because of gcc 2.96
|
||||
packaged with the distributions 7.0 and 7.1. You either have to use
|
||||
the comaptibility compiler package (compat-egcs and related packages,
|
||||
providing gcc 2.91), or even better, gcc 3.0.
|
||||
|
||||
It is recommended that you compile lame with gcc 3. For maximum performance,
|
||||
use the nasm assembler to compile assembly optimizations into lame.
|
||||
Try the following commands:
|
||||
|
||||
tar xfz lame-3.91.tar.gz
|
||||
cd lame-3.91
|
||||
export CC=gcc3
|
||||
./configure --with-fileio=lame --without-vorbis --disable-gtktest --enable-nasm --enable-expopt=full --prefix=/usr
|

|

Installing Ogg Vorbis
|
||||
---------------------
|
||||
|
||||
To install DarkIce, you need the following Ogg Vorbis 1.0 or later
|
||||
libraries (and related header files):
|
||||
|
||||
- libogg
|
||||
- libvoribs
|
||||
- libvorbisenc
|
||||
|
||||
installed on your system.
|
||||
|
||||
It is recommended that use install these to the usual system locations,
|
||||
/usr/lib, /usr/include, so that DarkIce will find the header files and
|
||||
libraries. Thus when configuring, add --prefix=/usr to the configure
|
||||
options.
|
||||
|
||||
Grab the latest Ogg Vorbis tarballs from
|
||||
http://www.xiph.org/ogg/vorbis/download.html
|
||||
|
||||
I took libogg-1.0.tar.gz and libvorbis-1.0.tar.gz. Go to the
|
||||
directory where you saved them, and issue the following commands:
|
||||
|
||||
tar xfz libogg-1.0.tar.gz
|
||||
cd libogg-1.0
|
||||
./configure --prefix=/usr
|

||||
cd libvorbis-1.0
|
||||
./configure --prefix=/usr
|
||||
make
|
||||
make install
|
||||
|
||||
For the install steps, you need to be root or have write permissions in the
|
||||
target directories.

1. What is DarkIce?
|
||||
-------------------
|
||||
|
||||
DarkIce is an IceCast, IceCast2 and ShoutCast live audio streamer. It
|
||||
takes audio input from a sound card, encodes it into mp3 and/or Ogg Vorbis,
|
||||
and sends the mp3 stream to one or more IceCast and/or ShoutCast servers,
|
||||
the Ogg Vorbis stream to one or more IceCast2 servers.
|
||||
|
||||
DarkIce website: http://code.google.com/p/darkice/
|
||||
|
||||
|
||||
2. Compiling and installing
|
||||
---------------------------
|
||||
|
||||
On how to compile and install, please read the file INSTALL. If you're
|
||||
impatient, try:
|
||||
|
||||
./configure
|
||||
make
|
||||
|
||||
The executable built is src/darkice.
|
||||
To install, try as root:
|
||||
|
||||
make install
|
||||
|
||||
|
||||
For documentation, try:
|
||||
|
||||
man darkice
|
||||
|
||||
|
||||
3. Reporting crashes
|
||||
--------------------
|
||||
|
||||
When DarkIce core dumps, please send the backtrace along with your error
|
||||
report to the darkice mailing list: http://www.freelists.org/list/darkice
|
||||
Alternatively you could file a bug report at http://code.google.com/p/darkice/issues/list
|
||||
To get the backtrace information, you need gdb, the GNU debugger:
|
||||
|
||||
1. configure and compile using the --with-debug option:
|
||||
|
||||
./configure --with-debug=yes
|
||||
make clean all
|
||||
|
||||
2. run darkice from within gdb:
|
||||
|
||||
gdb src/darkice
|
||||
|
||||
3. set parameters within gdb:
|
||||
|
||||
(gdb) set args -c darkice.cfg
|
||||
|
||||
4. run:
|
||||
|
||||
(gdb) run
|
||||
|
||||
5. after coredump, print the backtrace:
|
||||
|
||||
(gdb) bt

dnl @synopsis ACX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
|
||||
dnl
|
||||
dnl This macro figures out how to build C programs using POSIX
|
||||
dnl threads. It sets the PTHREAD_LIBS output variable to the threads
|
||||
dnl library and linker flags, and the PTHREAD_CFLAGS output variable
|
||||
dnl to any special C compiler flags that are needed. (The user can also
|
||||
dnl force certain compiler flags/libs to be tested by setting these
|
||||
dnl environment variables.)
|
||||
dnl
|
||||
dnl Also sets PTHREAD_CC to any special C compiler that is needed for
|
||||
dnl multi-threaded programs (defaults to the value of CC otherwise).
|
||||
dnl (This is necessary on AIX to use the special cc_r compiler alias.)
|
||||
dnl
|
||||
dnl NOTE: You are assumed to not only compile your program with these
|
||||
dnl flags, but also link it with them as well. e.g. you should link
|
||||
dnl with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
|
||||
dnl
|
||||
dnl If you are only building threads programs, you may wish to
|
||||
dnl use these variables in your default LIBS, CFLAGS, and CC:
|
||||
dnl
|
||||
dnl LIBS="$PTHREAD_LIBS $LIBS"
|
||||
dnl CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
|
||||
dnl CC="$PTHREAD_CC"
|
||||
dnl
|
||||
dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
|
||||
dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE
|
||||
dnl to that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
|
||||
dnl
|
||||
dnl ACTION-IF-FOUND is a list of shell commands to run if a threads
|
||||
dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands
|
||||
dnl to run it if it is not found. If ACTION-IF-FOUND is not specified,
|
||||
dnl the default action will define HAVE_PTHREAD.
|
||||
dnl
|
||||
dnl Please let the authors know if this macro fails on any platform,
|
||||
dnl or if you have any other suggestions or comments. This macro was
|
||||
dnl based on work by SGJ on autoconf scripts for FFTW (www.fftw.org)
|
||||
dnl (with help from M. Frigo), as well as ac_pthread and hb_pthread
|
||||
dnl macros posted by AFC to the autoconf macro repository. We are also

||||
dnl grateful for the helpful feedback of numerous users.

LAME is an educational tool to be used for learning about MP3 encoding. The
|
||||
goal of the LAME project is to use the open source model to improve the
|
||||
psycho acoustics, noise shaping and speed of MP3. Another goal of the LAME
|
||||
project is to use these improvements for the basis of a patent free audio
|
||||
compression codec for the GNU project.

This build is optimized for %{_target}.

darkice \- an icecast / shoutcast live audio streamer
|
||||
.SH SYNOPSIS
|
||||
.B darkice
|
||||
[options] -c config.file
|
||||
.SH DESCRIPTION
|
||||
.PP
|
||||
DarkIce as a live audio streamer. It records audio from an audio interface (e.g. sound card), encodes it and sends it to a streaming server.
|
||||
DarkIce can record from:
|
||||
|
||||
* OSS audio devices
|
||||
* ALSA audio devices
|
||||
* Solaris audio interface
|
||||
* Jack sources
|
||||
|
||||
DarkIce can encode in the following formats:
|
||||
|
||||
* mp3 - using the lame library
|
||||
* mp2 - using the twolame library
|
||||
* Ogg Vorbis
|
||||
* AAC - using the faac library
|
||||
* AAC HEv2 - using the libaacplus (3GPP reference code)
|
||||
|
||||
DarkIce can send the encoded stream to the following streaming servers:
|
||||
|
||||
* ShoutCast
|
||||
* IceCast 1.3.x and 2.x
|
||||
* Darwin Streaming Server
|
||||
|
||||
Darkice runs on the following operating systems:
|
||||
|
||||
* FreeBSD
|
||||
* Linux on intel and PowerPC
|
||||
* MacOS X
|
||||
* NetBSD / OpenBSD
|
||||
* SUN Solaris
|
||||
|
||||
.B DarkIce
|
||||
uses
|
||||
.SM POSIX
|
||||
real-time scheduling to keep up with sound card input.
|
||||
.SM POSIX
|
||||
real-time scheduling is only available if the program is run as root.
|
||||
Therefore it is recommended that
|
||||
.B DarkIce
|
||||
is run as root.
|
||||
|
||||
.SH OPTIONS
|
||||
.TP
|
||||

stream for 1 minute (60 seconds) from the audio device
|

.I /dev/dsp

reachable at

/* Description of constants:
|
||||
*
|
||||
* Npc - is the number of look-up values available for the lowpass filter
|
||||
* between the beginning of its impulse response and the "cutoff time"
|
||||
* of the filter. The cutoff time is defined as the reciprocal of the
|
||||
* lowpass-filter cut off frequence in Hz. For example, if the
|
||||
* lowpass filter were a sinc function, Npc would be the index of the
|
||||
* impulse-response lookup-table corresponding to the first zero-
|
||||
* crossing of the sinc function. (The inverse first zero-crossing
|
||||
* time of a sinc function equals its nominal cutoff frequency in Hz.)
|
||||
* Npc must be a power of 2 due to the details of the current
|
||||
* implementation. The default value of 512 is sufficiently high that
|
||||
* using linear interpolation to fill in between the table entries
|
||||
* gives approximately 16-bit accuracy in filter coefficients.
|
||||
*
|
||||
* Nhc - is log base 2 of Npc.
|
||||
*
|
||||
* Na - is the number of bits devoted to linear interpolation of the
|
||||
* filter coefficients.
|
||||
*
|
||||
* Np - is Na + Nhc, the number of bits to the right of the binary point
|
||||
* in the integer "time" variable. To the left of the point, it indexes
|
||||
* the input array (X), and to the right, it is interpreted as a number
|
||||
* between 0 and 1 sample of the input X. Np must be less than 16 in
|
||||
* this implementation.
|
||||
*
|
||||
* Nh - is the number of bits in the filter coefficients. The sum of Nh and
|
||||
* the number of bits in the input data (typically 16) cannot exceed 32.
|
||||
* Thus Nh should be 16. The largest filter coefficient should nearly
|
||||
* fill 16 bits (32767).
|
||||
*
|
||||
* Nb - is the number of bits in the input data. The sum of Nb and Nh cannot
|
||||
* exceed 32.
|
||||
*
|
||||
* Nhxn - is the number of bits to right shift after multiplying each input
|
||||
* sample times a filter coefficient. It can be as great as Nh and as
|
||||
* small as 0. Nhxn = Nh-2 gives 2 guard bits in the multiply-add
|
||||
* accumulation. If Nhxn=0, the accumulation will soon overflow 32 bits.
|
||||
*
|
||||
* Nhg - is the number of guard bits in mpy-add accumulation (equal to Nh-Nhxn)
|
||||
*
|
||||
* NLpScl - is the number of bits allocated to the unity-gain normalization
|
||||
* factor. The output of the lowpass filter is multiplied by LpScl and
|
||||
* then right-shifted NLpScl bits. To avoid overflow, we must have
|
||||
* Nb+Nhg+NLpScl < 32.

|

\brief Provides sample rate conversion.
|
||||
|
||||
This class will perform audio resampling. With the constructor you can choose the
|
||||
type of resampling to be done. Simple linear interpolation can be done by setting
|
||||
linear_interpolation to be TRUE in the constructor. The other two flags are
|
||||
ignored if this is set. If linear_interpolation is FALSE then some form of filtering
|
||||
will be done. IF high_quality is FALSE then a small filter will be performed.
|
||||
If high_quality is TRUE then a large filter (higher quality) will be performed. For
|
||||
both the small and large filters another parameter can be specified, filter_interpolation.
|
||||
With filter_interpolation set then the filter coefficients used for both the small and
|
||||
large filtering will be interpolated as well.
|
||||
|
||||
This class was designed to stream audio data. It also expects audio data as 16 bit values.
|
||||
Each time a new stream is started some initialization needs to be done. Thus the function
|
||||
initialize should be called to initialize everything. This initialize function will set
|
||||
the conversion factor as well as a multiplecation factor for volume. The volume only
|
||||
applies to the small and large filter. Since this filter uses a history of the audio data
|
||||
it is possible for it to vary in amplitude. This allows users to scale the data. This
|
||||
class will work on any number of channels. Once everything is specified then resample
|
||||
should be called as many times as is necessary to process all the data. The value
|
||||
inCount will be returned indicating how many inArray samples were actually used to
|
||||
produce the output. This value can be used to indicate where the next block of
|
||||
inArray data should start. The resample function is driven by the outCount value
|
||||
specified. The inArray should contain at least:
|
||||
outCount / factor + extra_samples.
|
||||
extra_samples depends on the type of filtering done. As a rule of thumb 50 should be
|
||||
adequate for any type of filter.
