10 GNU GENERAL PUBLIC LICENSE
11 Version 2, June 1991
12
13 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
14 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
15 Everyone is permitted to copy and distribute verbatim copies
16 of this license document, but changing it is not allowed.
17
18 Preamble
19
20 The licenses for most software are designed to take away your
21 freedom to share and change it. By contrast, the GNU General Public
22 License is intended to guarantee your freedom to share and change free
23 software--to make sure the software is free for all its users. This
24 General Public License applies to most of the Free Software
25 Foundation's software and to any other program whose authors commit to
26 using it. (Some other Free Software Foundation software is covered by
27 the GNU Library General Public License instead.) You can apply it to
28 your programs, too.
29
30 When we speak of free software, we are referring to freedom, not
31 price. Our General Public Licenses are designed to make sure that you
32 have the freedom to distribute copies of free software (and charge for
33 this service if you wish), that you receive source code or can get it
34 if you want it, that you can change the software or use pieces of it
35 in new free programs; and that you know you can do these things.
36
37 To protect your rights, we need to make restrictions that forbid
38 anyone to deny you these rights or to ask you to surrender the rights.
39 These restrictions translate to certain responsibilities for you if you
40 distribute copies of the software, or if you modify it.
41
42 For example, if you distribute copies of such a program, whether
43 gratis or for a fee, you must give the recipients all the rights that
44 you have. You must make sure that they, too, receive or can get the
45 source code. And you must show them these terms so they know their
46 rights.
47
48 We protect your rights with two steps: (1) copyright the software, and
49 (2) offer you this license which gives you legal permission to copy,
50 distribute and/or modify the software.
51
52 Also, for each author's protection and ours, we want to make certain
53 that everyone understands that there is no warranty for this free
54 software. If the software is modified by someone else and passed on, we
55 want its recipients to know that what they have is not the original, so
56 that any problems introduced by others will not reflect on the original
57 authors' reputations.
58
59 Finally, any free program is threatened constantly by software
60 patents. We wish to avoid the danger that redistributors of a free
61 program will individually obtain patent licenses, in effect making the
62 program proprietary. To prevent this, we have made it clear that any
63 patent must be licensed for everyone's free use or not licensed at all.
64
65 The precise terms and conditions for copying, distribution and
66 modification follow.
67
68 GNU GENERAL PUBLIC LICENSE
69 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
70
71 0. This License applies to any program or other work which contains
72 a notice placed by the copyright holder saying it may be distributed
73 under the terms of this General Public License. The "Program", below,
74 refers to any such program or work, and a "work based on the Program"
75 means either the Program or any derivative work under copyright law:
76 that is to say, a work containing the Program or a portion of it,
77 either verbatim or with modifications and/or translated into another
78 language. (Hereinafter, translation is included without limitation in
79 the term "modification".) Each licensee is addressed as "you".
80
81 Activities other than copying, distribution and modification are not
82 covered by this License; they are outside its scope. The act of
83 running the Program is not restricted, and the output from the Program
84 is covered only if its contents constitute a work based on the
85 Program (independent of having been made by running the Program).
86 Whether that is true depends on what the Program does.
87
88 1. You may copy and distribute verbatim copies of the Program's
89 source code as you receive it, in any medium, provided that you
90 conspicuously and appropriately publish on each copy an appropriate
91 copyright notice and disclaimer of warranty; keep intact all the
92 notices that refer to this License and to the absence of any warranty;
93 and give any other recipients of the Program a copy of this License
94 along with the Program.
95
96 You may charge a fee for the physical act of transferring a copy, and
97 you may at your option offer warranty protection in exchange for a fee.
98
99 2. You may modify your copy or copies of the Program or any portion
100 of it, thus forming a work based on the Program, and copy and
101 distribute such modifications or work under the terms of Section 1
102 above, provided that you also meet all of these conditions:
103
104 a) You must cause the modified files to carry prominent notices
105 stating that you changed the files and the date of any change.
106
107 b) You must cause any work that you distribute or publish, that in
108 whole or in part contains or is derived from the Program or any
109 part thereof, to be licensed as a whole at no charge to all third
110 parties under the terms of this License.
111
112 c) If the modified program normally reads commands interactively
113 when run, you must cause it, when started running for such
114 interactive use in the most ordinary way, to print or display an
115 announcement including an appropriate copyright notice and a
116 notice that there is no warranty (or else, saying that you provide
117 a warranty) and that users may redistribute the program under
118 these conditions, and telling the user how to view a copy of this
119 License. (Exception: if the Program itself is interactive but
120 does not normally print such an announcement, your work based on
121 the Program is not required to print an announcement.)
122
123 These requirements apply to the modified work as a whole. If
124 identifiable sections of that work are not derived from the Program,
125 and can be reasonably considered independent and separate works in
126 themselves, then this License, and its terms, do not apply to those
127 sections when you distribute them as separate works. But when you
128 distribute the same sections as part of a whole which is a work based
129 on the Program, the distribution of the whole must be on the terms of
130 this License, whose permissions for other licensees extend to the
131 entire whole, and thus to each and every part regardless of who wrote it.
132
133 Thus, it is not the intent of this section to claim rights or contest
134 your rights to work written entirely by you; rather, the intent is to
135 exercise the right to control the distribution of derivative or
136 collective works based on the Program.
137
138 In addition, mere aggregation of another work not based on the Program
139 with the Program (or with a work based on the Program) on a volume of
140 a storage or distribution medium does not bring the other work under
141 the scope of this License.
142
143 3. You may copy and distribute the Program (or a work based on it,
144 under Section 2) in object code or executable form under the terms of
145 Sections 1 and 2 above provided that you also do one of the following:
146
147 a) Accompany it with the complete corresponding machine-readable
148 source code, which must be distributed under the terms of Sections
149 1 and 2 above on a medium customarily used for software interchange; or,
150
151 b) Accompany it with a written offer, valid for at least three
152 years, to give any third party, for a charge no more than your
153 cost of physically performing source distribution, a complete
154 machine-readable copy of the corresponding source code, to be
155 distributed under the terms of Sections 1 and 2 above on a medium
156 customarily used for software interchange; or,
157
158 c) Accompany it with the information you received as to the offer
159 to distribute corresponding source code. (This alternative is
160 allowed only for noncommercial distribution and only if you
161 received the program in object code or executable form with such
162 an offer, in accord with Subsection b above.)
163
164 The source code for a work means the preferred form of the work for
165 making modifications to it. For an executable work, complete source
166 code means all the source code for all modules it contains, plus any
167 associated interface definition files, plus the scripts used to
168 control compilation and installation of the executable. However, as a
169 special exception, the source code distributed need not include
170 anything that is normally distributed (in either source or binary
171 form) with the major components (compiler, kernel, and so on) of the
172 operating system on which the executable runs, unless that component
173 itself accompanies the executable.
174
175 If distribution of executable or object code is made by offering
176 access to copy from a designated place, then offering equivalent
177 access to copy the source code from the same place counts as
178 distribution of the source code, even though third parties are not
179 compelled to copy the source along with the object code.
180
181 4. You may not copy, modify, sublicense, or distribute the Program
182 except as expressly provided under this License. Any attempt
183 otherwise to copy, modify, sublicense or distribute the Program is
184 void, and will automatically terminate your rights under this License.
185 However, parties who have received copies, or rights, from you under
186 this License will not have their licenses terminated so long as such
187 parties remain in full compliance.
188
189 5. You are not required to accept this License, since you have not
190 signed it. However, nothing else grants you permission to modify or
191 distribute the Program or its derivative works. These actions are
192 prohibited by law if you do not accept this License. Therefore, by
193 modifying or distributing the Program (or any work based on the
194 Program), you indicate your acceptance of this License to do so, and
195 all its terms and conditions for copying, distributing or modifying
196 the Program or works based on it.
197
198 6. Each time you redistribute the Program (or any work based on the
199 Program), the recipient automatically receives a license from the
200 original licensor to copy, distribute or modify the Program subject to
201 these terms and conditions. You may not impose any further
202 restrictions on the recipients' exercise of the rights granted herein.
203 You are not responsible for enforcing compliance by third parties to
204 this License.
205
206 7. If, as a consequence of a court judgment or allegation of patent
207 infringement or for any other reason (not limited to patent issues),
208 conditions are imposed on you (whether by court order, agreement or
209 otherwise) that contradict the conditions of this License, they do not
210 excuse you from the conditions of this License. If you cannot
211 distribute so as to satisfy simultaneously your obligations under this
212 License and any other pertinent obligations, then as a consequence you
213 may not distribute the Program at all. For example, if a patent
214 license would not permit royalty-free redistribution of the Program by
215 all those who receive copies directly or indirectly through you, then
216 the only way you could satisfy both it and this License would be to
217 refrain entirely from distribution of the Program.
218
219 If any portion of this section is held invalid or unenforceable under
220 any particular circumstance, the balance of the section is intended to
221 apply and the section as a whole is intended to apply in other
222 circumstances.
223
224 It is not the purpose of this section to induce you to infringe any
225 patents or other property right claims or to contest validity of any
226 such claims; this section has the sole purpose of protecting the
227 integrity of the free software distribution system, which is
228 implemented by public license practices. Many people have made
229 generous contributions to the wide range of software distributed
230 through that system in reliance on consistent application of that
231 system; it is up to the author/donor to decide if he or she is willing
232 to distribute software through any other system and a licensee cannot
233 impose that choice.
234
235 This section is intended to make thoroughly clear what is believed to
236 be a consequence of the rest of this License.
237
238 8. If the distribution and/or use of the Program is restricted in
239 certain countries either by patents or by copyrighted interfaces, the
240 original copyright holder who places the Program under this License
241 may add an explicit geographical distribution limitation excluding
242 those countries, so that distribution is permitted only in or among
243 countries not thus excluded. In such case, this License incorporates
244 the limitation as if written in the body of this License.
245
246 9. The Free Software Foundation may publish revised and/or new versions
247 of the General Public License from time to time. Such new versions will
248 be similar in spirit to the present version, but may differ in detail to
249 address new problems or concerns.
250
251 Each version is given a distinguishing version number. If the Program
252 specifies a version number of this License which applies to it and "any
253 later version", you have the option of following the terms and conditions
254 either of that version or of any later version published by the Free
255 Software Foundation. If the Program does not specify a version number of
256 this License, you may choose any version ever published by the Free Software
257 Foundation.
258
259 10. If you wish to incorporate parts of the Program into other free
260 programs whose distribution conditions are different, write to the author
261 to ask for permission. For software which is copyrighted by the Free
262 Software Foundation, write to the Free Software Foundation; we sometimes
263 make exceptions for this. Our decision will be guided by the two goals
264 of preserving the free status of all derivatives of our free software and
265 of promoting the sharing and reuse of software generally.
266
267 NO WARRANTY
268
269 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
270 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
271 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
272 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
273 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
274 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
275 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
276 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
277 REPAIR OR CORRECTION.
278
279 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
280 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
281 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
282 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
283 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
284 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
285 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
286 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
287 POSSIBILITY OF SUCH DAMAGES.
288
289 END OF TERMS AND CONDITIONS
290
291 How to Apply These Terms to Your New Programs
292
293 If you develop a new program, and you want it to be of the greatest
294 possible use to the public, the best way to achieve this is to make it
295 free software which everyone can redistribute and change under these terms.
296
297 To do so, attach the following notices to the program. It is safest
298 to attach them to the start of each source file to most effectively
299 convey the exclusion of warranty; and each file should have at least
300 the "copyright" line and a pointer to where the full notice is found.
301
302 <one line to give the program's name and a brief idea of what it does.>
303 Copyright (C) 19yy <name of author>
304
305 This program is free software; you can redistribute it and/or modify
306 it under the terms of the GNU General Public License as published by
307 the Free Software Foundation; either version 2 of the License, or
308 (at your option) any later version.
309
310 This program is distributed in the hope that it will be useful,
311 but WITHOUT ANY WARRANTY; without even the implied warranty of
312 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
313 GNU General Public License for more details.
314
315 You should have received a copy of the GNU General Public License
316 along with this program; if not, write to the Free Software
317 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
318
319
320 Also add information on how to contact you by electronic and paper mail.
321
322 If the program is interactive, make it output a short notice like this
323 when it starts in an interactive mode:
324
325 Gnomovision version 69, Copyright (C) 19yy name of author
326 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
327 This is free software, and you are welcome to redistribute it
328 under certain conditions; type `show c' for details.
329
330 The hypothetical commands `show w' and `show c' should show the appropriate
331 parts of the General Public License. Of course, the commands you use may
332 be called something other than `show w' and `show c'; they could even be
333 mouse-clicks or menu items--whatever suits your program.
334
335 You should also get your employer (if you work as a programmer) or your
336 school, if any, to sign a "copyright disclaimer" for the program, if
337 necessary. Here is a sample; alter the names:
338
339 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
340 `Gnomovision' (which makes passes at compilers) written by James Hacker.
341
342 <signature of Ty Coon>, 1 April 1989
343 Ty Coon, President of Vice
344
345 This General Public License does not permit incorporating your program into
346 proprietary programs. If your program is a subroutine library, you may
347 consider it more useful to permit linking proprietary applications with the
348 library. If this is what you want to do, use the GNU Library General
349 Public License instead of this License.

130 REQUIRE_ORDER means don't recognize them as options;
131 stop option processing when the first non-option is seen.
132 This is what Unix does.
133 This mode of operation is selected by either setting the environment
134 variable POSIXLY_CORRECT, or using `+' as the first character
135 of the list of option characters.
136
137 PERMUTE is the default. We permute the contents of ARGV as we scan,
138 so that eventually all the non-options are at the end. This allows options
139 to be given in any order, even with programs that were not written to
140 expect this.
141
142 RETURN_IN_ORDER is an option available to programs that were written
143 to expect options and other ARGV-elements in any order and that care about
144 the ordering of the two. We describe each non-option ARGV-element
145 as if it were the argument of an option with character code 1.
146 Using `-' as the first character of the list of option characters
147 selects this mode of operation.
148
149 The special argument `--' forces an end of option-scanning regardless
150 of the value of `ordering'. In the case of RETURN_IN_ORDER, only

271
272 If an element of ARGV starts with '-', and is not exactly "-" or "--",
273 then it is an option element. The characters of this element
274 (aside from the initial '-') are option characters. If `getopt'
275 is called repeatedly, it returns successively each of the option characters
276 from each of the option elements.
277
278 If `getopt' finds another option character, it returns that character,
279 updating `optind' and `nextchar' so that the next call to `getopt' can
280 resume the scan with the following option character or ARGV-element.
281
282 If there are no more option characters, `getopt' returns `EOF'.
283 Then `optind' is the index in ARGV of the first ARGV-element
284 that is not an option. (The ARGV-elements have been permuted
285 so that those that are not options now come last.)
286
287 OPTSTRING is a string containing the legitimate option characters.
288 If an option character is seen that is not listed in OPTSTRING,
289 return BAD_OPTION after printing an error message. If you set `opterr' to
290 zero, the error message is suppressed but we still return BAD_OPTION.
291
292 If a char in OPTSTRING is followed by a colon, that means it wants an arg,
293 so the following text in the same ARGV-element, or the text of the following
294 ARGV-element, is returned in `optarg'. Two colons mean an option that
295 wants an optional arg; if there is text in the current ARGV-element,
296 it is returned in `optarg', otherwise `optarg' is set to zero.
297
298 If OPTSTRING starts with `-' or `+', it requests different methods of
299 handling the non-option ARGV-elements.
300 See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
301
302 Long-named options begin with `--' instead of `-'.
303 Their names may be abbreviated as long as the abbreviation is unique
304 or is an exact match for some defined option. If they have an
305 argument, it follows the option name in the same ARGV-element, separated
306 from the option name by a `=', or else the in next ARGV-element.
307 When `getopt' finds a long-named option, it returns 0 if that option's
308 `flag' field is nonzero, the value of the option's `val' field
309 if the `flag' field is zero.
310
311 The elements of ARGV aren't really const, because we permute them.
312 But we pretend they're const in the prototype to be compatible
313 with other systems.
314
315 LONGOPTS is a vector of `struct option' terminated by an
316 element containing a name which is zero.
317
318 LONGIND returns the index in LONGOPT of the long-named option found.
319 It is only valid when a long-named option has been found by the most
320 recent call.
321
322 If LONG_ONLY is nonzero, '-' as well as '--' can introduce

73 a compiled-in constant, such as set a value from `optarg', set the
74 option's `flag' field to zero and its `val' field to a nonzero
75 value (the equivalent single-letter option character, if there is
76 one). For long options that have a zero `flag' field, `getopt'

78 %description xmms
79 The AAC xmms input plugin for xmms recognizes AAC files by an
80 .aac extension.
81 This MP4 xmms plugin reads AAC files with and without ID3 tags (version 2.x).
82 AAC files are MPEG2 or MPEG4 files that can be found in MPEG4 audio files
83 (.mp4). MPEG4 files with AAC inside can be read by RealPlayer or Quicktime.

40 * VLADIMIR Z. MESAROVIC , RAGHUNATH RAO, MIROSLAV V. DOKIC, and SACHIN DEO
41 * AES paper 5436
42 *
43 * 2 methods are used for huffman decoding:
44 * - binary search
45 * - 2-step table lookup
46 *
47 * The choice of the "optimal" method is based on the fact that if the
48 * memory size for the Two-step is exorbitantly high then the decision
49 * is Binary search for that codebook. However, for marginally more memory
50 * size, if Twostep outperforms even the best case of Binary then the
51 * decision is Two-step for that codebook.
52 *
53 * The following methods are used for the different tables.
54 * codebook "optimal" method
55 * HCB_1 2-Step
56 * HCB_2 2-Step
57 * HCB_3 Binary
58 * HCB_4 2-Step

30 /* RVLC scalefactor decoding
31 *
32 * RVLC works like this:
33 * 1. Only symmetric huffman codewords are used
34 * 2. Total length of the scalefactor data is stored in the bitsream
35 * 3. Scalefactors are DPCM coded
36 * 4. Next to the starting value for DPCM the ending value is also stored
37 *
38 * With all this it is possible to read the scalefactor data from 2 sides.
39 * If there is a bit error in the scalefactor data it is possible to start
40 * decoding from the other end of the data, to find all but 1 scalefactor.

529 For ONLY_LONG_SEQUENCE windows (num_window_groups = 1,
530 window_group_length[0] = 1) the spectral data is in ascending spectral
531 order.
532 For the EIGHT_SHORT_SEQUENCE window, the spectral order depends on the
533 grouping in the following manner:
534 - Groups are ordered sequentially
535 - Within a group, a scalefactor band consists of the spectral data of all
536 grouped SHORT_WINDOWs for the associated scalefactor window band. To
537 clarify via example, the length of a group is in the range of one to eight
538 SHORT_WINDOWs.
539 - If there are eight groups each with length one (num_window_groups = 8,
540 window_group_length[0..7] = 1), the result is a sequence of eight spectra,
541 each in ascending spectral order.
542 - If there is only one group with length eight (num_window_groups = 1,
543 window_group_length[0] = 8), the result is that spectral data of all eight
544 SHORT_WINDOWs is interleaved by scalefactor window bands.
545 - Within a scalefactor window band, the coefficients are in ascending
546 spectral order.

2 You will need to have mpeg4ip installed. If you install it on the same drive, with the top level directory
3 name of /mpeg4ip, you will have to do nothing other than move the faad2_plugin.dll from the Release or
4 Debug directory to the same directory as the other mpeg4ip plugins.
5
6 If you install it somewhere else, you will have to change the include paths and link paths in the project
7 settings for faad2_plugin to the proper directory. Look for /mpeg4ip (or \mpeg4ip) and change all occurances
8 of these in the file.
9
10 It might be best to hand-edit the faad_plugin.sdp file with wordpad and use the search and replace function.⏎

7
8 About.
9 This plugin is a merge between aac and mp4 plugin. so now you could read
10 all new and old files encoded with different encoder and different format
11 (for the aac part). This is possible since the libfaad2 allow to read
12 old aac ADTS format.
