|

// | Example wrapper class to extract information from audio files |
|
||||
// | through getID3(). |
|
||||
// | |
|
||||
// | getID3() returns a lot of information. Much of this information is |
|
||||
// | not needed for the end-application. It is also possible that some |
|
||||
// | users want to extract specific info. Modifying getID3() files is a |
|
||||
// | bad idea, as modifications needs to be done to future versions of |
|
||||
// | getID3(). |
|
||||
// | |
|
||||
// | Modify this wrapper class instead. This example extracts certain |
|
||||
// | fields only and adds a new root value - encoder_options if possible. |
|
||||
// | It also checks for mp3 files with wave headers. |
|
||||
// +----------------------------------------------------------------------+

getID3() Commercial License
|
||||
===========================
|
||||
|
||||
getID3() is licensed under the "GNU Public License" (GPL) and/or the
|
||||
"getID3() Commercial License" (gCL). This document describes the gCL.
|
||||
|
||||
---------------------------------------------------------------------
|
||||
|
||||
The license is non-exclusively granted to a single person or company,
|
||||
per payment of the license fee, for the lifetime of that person or
|
||||
company. The license is non-transferrable.
|
||||
|
||||
The gCL grants the licensee the right to use getID3() in commercial
|
||||
closed-source projects. Modifications may be made to getID3() with no
|
||||
obligation to release the modified source code. getID3() (or pieces
|
||||
thereof) may be included in any number of projects authored (in whole
|
||||
or in part) by the licensee.
|
||||
|
||||
The licensee may use any version of getID3(), past, present or future,
|
||||
as is most convenient. This license does not entitle the licensee to
|
||||
receive any technical support, updates or bugfixes, except as such are
|
||||
made publicly available to all getID3() users.
|
||||
|
||||
The licensee may not sub-license getID3() itself, meaning that any
|
||||
commercially released product containing all or parts of getID3() must
|
||||
have added functionality beyond what is available in getID3();
|
||||
getID3() itself may not be re-licensed by the licensee.

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
|
||||

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.

Quick Start
|
||||
===========================================================================
|
||||
|
||||
Q: How can I check that getID3() works on my server/files?
|
||||
A: Unzip getID3() to a directory, then access /demos/demo.browse.php
|
||||
|
||||
|
||||
|
||||
Sourceforge Notification
|
||||
===========================================================================
|
||||
|
||||
It's highly recommended that you sign up for notification from
|
||||
Sourceforge for when new versions are released. Please visit:
|
||||
http://sourceforge.net/project/showfiles.php?group_id=55859
|
||||
and click the little "monitor package" icon/link. If you're
|
||||
previously signed up for the mailing list, be aware that it has
|
||||
been discontinued, only the automated Sourceforge notification
|
||||
will be used from now on.

Requirements
|
||||
===========================================================================
|
||||
|
||||
* PHP 4.2.0 (or higher) for getID3() 1.7.8 (and up).
|
||||
* PHP 5.0.0 (or higher) for getID3() 2.0.0 (and up).
|
||||
* at least 4MB memory for PHP. 8MB is highly recommended.
|
||||
12MB is required with all modules loaded.
|
||||
|
||||
|
||||
|
||||
Usage
|
||||
===========================================================================
|
||||
|
||||
See /demos/demo.basic.php for a very basic use of getID3() with no
|
||||
fancy output, just scanning one file.
|
||||
|
||||
See structure.txt for the returned data structure.
|
||||
|
||||
*> For an example of a complete directory-browsing, <*
|
||||
*> file-scanning implementation of getID3(), please run <*
|
||||
*> /demos/demo.browse.php <*
|
||||
|
||||
See /demos/demo.mysql.php for a sample recursive scanning code that
|
||||
scans every file in a given directory, and all sub-directories, stores
|
||||
the results in a database and allows various analysis / maintenance
|
||||
operations
|
||||
|
||||
To analyze remote files over HTTP or FTP you need to copy the file
|
||||
locally first before running getID3(). Your code would look something
|
||||
like this:
|
||||
|
||||
// Copy remote file locally to scan with getID3()
|
||||
$remotefilename = 'http://www.example.com/filename.mp3';
|
||||
if ($fp_remote = fopen($remotefilename, 'rb')) {
|
||||
$localtempfilename = tempnam('/tmp', 'getID3');
|
||||
if ($fp_local = fopen($localtempfilename, 'wb')) {
|
||||
while ($buffer = fread($fp_remote, 8192)) {
|
||||
fwrite($fp_local, $buffer);
|
||||
}
|
||||
fclose($fp_local);
|
||||
|
||||
// Initialize getID3 engine
|
||||
$getID3 = new getID3;
|
||||
|
||||
$ThisFileInfo = $getID3->analyze($filename);
|
||||
|
||||
// Delete temporary file
|
||||
unlink($localtempfilename);
|
||||
}
|
||||
fclose($fp_remote);
|
||||
}
|
||||
|
||||
|
||||
See /demos/demo.write.php for how to write tags.
|
||||
|
||||
|
||||
|
||||
What does the returned data structure look like?
|
||||
===========================================================================
|
||||
|
||||
See structure.txt
|
||||
|
||||
It is recommended that you look at the output of
|
||||
/demos/demo.browse.php scanning the file(s) you're interested in to
|
||||
confirm what data is actually returned for any particular filetype in
|
||||
general, and your files in particular, as the actual data returned
|
||||
may vary considerably depending on what information is available in
|
||||
the file itself.
|
||||
|
||||
|
||||
|
||||
Notes
|
||||
===========================================================================
|
||||
|
||||
getID3() 1.7:
|
||||
If the format parser encounters a critical problem, it will return
|
||||
something in $fileinfo['error'], describing the encountered error. If
|
||||
a less critical error or notice is generated it will appear in
|
||||
$fileinfo['warning']. Both keys may contain more than one warning or
|
||||
error. If something is returned in ['error'] then the file was not
|
||||
correctly parsed and returned data may or may not be correct and/or
|
||||
complete. If something is returned in ['warning'] (and not ['error'])
|
||||
then the data that is returned is OK - usually getID3() is reporting
|
||||
errors in the file that have been worked around due to known bugs in
|
||||
other programs. Some warnings may indicate that the data that is
|
||||
returned is OK but that some data could not be extracted due to
|
||||
errors in the file.
|
||||
|
||||
getID3() 2.0:
|
||||
See above except errors are thrown (so you will only get one error).
|
||||
|
||||
|
||||
|
||||
Disclaimer
|
||||
===========================================================================
|
||||
|
||||
getID3() has been tested on many systems, on many types of files,
|
||||
under many operating systems, and is generally believe to be stable
|
||||
and safe. That being said, there is still the chance there is an
|
||||
undiscovered and/or unfixed bug that may potentially corrupt your
|
||||
file, especially within the writing functions. By using getID3() you
|
||||
agree that it's not my fault if any of your files are corrupted.
|
||||
In fact, I'm not liable for anything :)

FAQ:
|
||||
Q: Can I use getID3() in my program? Do I need a commercial license?
|
||||
A: You're generally free to use getID3 however you see fit. The only
|
||||
case in which you would require a commercial license is if you're
|
||||
selling your closed-source program that integrates getID3. If you
|
||||
sell your program including a copy of getID3, that's fine as long
|
||||
as you include a copy of the sourcecode when you sell it. Or you
|
||||
can distribute your code without getID3 and say "download it from
|
||||
getid3.sourceforge.net"
|
||||
|
||||
|
||||
|
||||

Known Bugs/Issues in getID3() that may be fixed eventually
|
||||
===========================================================================
|
||||
|
||||
* Cannot determine bitrate for MPEG video with VBR video data
|
||||
(need documentation)
|
||||
* Interlace/progressive cannot be determined for MPEG video
|
||||
(need documentation)
|
||||
* MIDI playtime is sometimes inaccurate
|
||||
* AAC-RAW mode files cannot be identified
|
||||
* WavPack-RAW mode files cannot be identified
|
||||
* mp4 files report lots of "Unknown QuickTime atom type"
|
||||
(need documentation)
|
||||
* Encrypted ASF/WMA/WMV files warn about "unhandled GUID
|
||||
ASF_Content_Encryption_Object"
|
||||
* Bitrate split between audio and video cannot be calculated for
|
||||
NSV, only the total bitrate. (need documentation)
|
||||
* All Ogg formats (Vorbis, OggFLAC, Speex) are affected by the
|
||||
problem of large VorbisComments spanning multiple Ogg pages, but
|
||||
but only OggVorbis files can be processed with vorbiscomment.
|
||||
* The version of "head" supplied with Mac OS 10.2.8 (maybe other
|
||||
versions too) does only understands a single option (-n) and
|
||||
therefore fails. getID3 ignores this and returns wrong md5_data.
|
||||
|
||||
|
||||
|
||||
Known Bugs/Issues in getID3() that cannot be fixed
|
||||
--------------------------------------------------
|
||||
|
||||
* Files larger than 2GB cannot always be parsed fully by getID3()
|
||||
due to limitations in the PHP filesystem functions.
|
||||
NOTE: Since v1.7.8b3 there is partial support for larger-than-
|
||||
2GB files, most of which will parse OK, as long as no critical
|
||||
data is located beyond the 2GB offset.
|
||||
Known will-work:
|
||||
* ZIP (format doesn't support files >2GB)
|
||||
* FLAC (current encoders don't support files >2GB)
|
||||
Known will-not-work:
|
||||
* ID3v1 tags (always located at end-of-file)
|
||||
* Lyrics3 tags (always located at end-of-file)
|
||||
* APE tags (always located at end-of-file)
|
||||
Maybe-will-work:
|
||||
* Quicktime (will work if needed metadata is before 2GB offset,
|
||||
that is if the file has been hinted/optimized for streaming)
|
||||
* RIFF.WAV (should work fine, but gives warnings about not being
|
||||
able to parse all chunks)
|
||||
* RIFF.AVI (playtime will probably be wrong, is only based on
|
||||
"movi" chunk that fits in the first 2GB, should issue error
|
||||
to show that playtime is incorrect. Other data should be mostly
|
||||
correct, assuming that data is constant throughout the file)
|
||||
|
||||
|
||||
|
||||
Known Bugs/Issues in other programs
|
||||
-----------------------------------
|
||||
|
||||
* Winamp (up to v2.80 at least) does not support ID3v2.4 tags,
|
||||
only ID3v2.3
|
||||
see: http://forums.winamp.com/showthread.php?postid=387524
|
||||
* Some versions of Helium2 (www.helium2.com) do not write
|
||||
ID3v2.4-compliant Frame Sizes, even though the tag is marked
|
||||
as ID3v2.4) (detected by getID3())
|
||||
* MP3ext V3.3.17 places a non-compliant padding string at the end
|
||||
of the ID3v2 header. This is supposedly fixed in v3.4b21 but
|
||||
only if you manually add a registry key. This fix is not yet
|
||||
confirmed. (detected by getID3())
|
||||
* CDex v1.40 (fixed by v1.50b7) writes non-compliant Ogg comment
|
||||
strings, supposed to be in the format "NAME=value" but actually
|
||||
written just "value" (detected by getID3())
|
||||
* Oggenc 0.9-rc3 flags the encoded file as ABR whether it's
|
||||
actually ABR or VBR.
|
||||
* iTunes (versions "X v2.0.3", "v3.0.1" are known-guilty, probably
|
||||
other versions are too) writes ID3v2.3 comment tags using a
|
||||
frame name 'COM ' which is not valid for ID3v2.3+ (it's an
|
||||
ID3v2.2-style frame name) (detected by getID3())
|
||||
* MP2enc does not encode mono CBR MP2 files properly (half speed
|
||||
sound and double playtime)
|
||||
* MP2enc does not encode mono VBR MP2 files properly (actually
|
||||
encoded as stereo)
|
||||
* tooLAME does not encode mono VBR MP2 files properly (actually
|
||||
encoded as stereo)
|
||||
* AACenc encodes files in VBR mode (actually ABR) even if CBR is
|
||||
specified
|
||||
* AAC/ADIF - bitrate_mode = cbr for vbr files
|
||||
* LAME 3.90-3.92 prepends one frame of null data (space for the
|
||||
LAME/VBR header, but it never gets written) when encoding in CBR
|
||||
mode with the DLL
|
||||
* Ahead Nero encodes TwinVQF with a DSIZ value (which is supposed
|
||||
to be the filesize in bytes) of "0" for TwinVQF v1.0 and "1" for
|
||||
TwinVQF v2.0 (detected by getID3())
|
||||
* Ahead Nero encodes TwinVQF files 1 second shorter than they
|
||||
should be
|
||||
* AAC-ADTS files are always actually encoded VBR, even if CBR mode
|
||||
is specified (the CBR-mode switches on the encoder enable ABR
|
||||
mode, not CBR as such, but it's not possible to tell the
|
||||
difference between such ABR files and true VBR)
|
||||
* STREAMINFO.audio_signature in OggFLAC is always null. "The reason
|
||||
it's like that is because there is no seeking support in
|
||||
libOggFLAC yet, so it has no way to go back and write the
|
||||
computed sum after encoding. Seeking support in Ogg FLAC is the
|
||||
#1 item for the next release." - Josh Coalson (FLAC developer)
|
||||
NOTE: getID3() will calculate md5_data in a method similar to
|
||||
other file formats, but that value cannot be compared to the
|
||||
md5_data value from FLAC data in a FLAC file format.
|
||||
* STREAMINFO.audio_signature is not calculated in FLAC v0.3.0 &
|
||||
v0.4.0 - getID3() will calculate md5_data in a method similar to
|
||||
other file formats, but that value cannot be compared to the
|
||||
md5_data value from FLAC v0.5.0+
|
||||
* RioPort (various versions including 2.0 and 3.11) tags ID3v2 with
|
||||
a WCOM frame that has no data portion
|
||||
* Earlier versions of Coolplayer adds illegal ID3 tags to Ogg Vorbis
|
||||
files, thus making them corrupt.
|
||||
* Meracl ID3 Tag Writer v1.3.4 (and older) incorrectly truncates the
|
||||
last byte of data from an MP3 file when appending a new ID3v1 tag.
|
||||
(detected by getID3())
|
||||
* Lossless-Audio files encoded with and without the -noseek switch
|
||||
do actually differ internally and therefore cannot match md5_data
|
||||
* iTunes has been known to append a new ID3v1 tag on the end of an
|
||||
existing ID3v1 tag when ID3v2 tag is also present
|
||||
(detected by getID3())
