[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, 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 and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, 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 library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete 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 distribute a copy of this License along with the Library. 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 Library or any portion of it, thus forming a work based on the Library, 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) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, 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 Library, 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 Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you 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. If distribution of 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 satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be 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. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library 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. 9. 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 Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library 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 with this License. 11. 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 Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library 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 Library. 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. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library 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. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser 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 Library 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 Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, 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 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "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 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. 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 LIBRARY 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 LIBRARY (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 LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), 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 Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. 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. Copyright (C) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version. This library 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 Lesser General Public License for more details. You should have received a copy of the GNU Lesser General Public License along with this library; 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. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary.

Takes directly a stream url and dumps the tracks on the specified file/s and standard output, depending on the settings. fPls [options] [fIcy options] Playlist manager. Reads a playlist (local or remote) and manages fIcy retries/timeouts/errors, forwarding the specified flags. fResync [options] file MPEG resyncing utility. Re-aligns head frame headers on dumped or broken files. Usually needed for embedded hardware decoders or editing software. fIcy options ~~~~~~~~~~~~ -d Do not dump the output to stdout. Useful when only ripping. -E num Enumerate files when song title [metadata] changes, starting at num. When 0, fIcy will try to find the highest unused file number automatically. Uses -o as a prefix. -h Help -c Do not clobber files. -m Use song title [metadata] when naming files. Uses -o as prefix. -n If the file exists create new one with .n as suffix. -p When dumping to stdout consider writing errors as transient (that is: flush the output buffer until stdout is ready). Useful when you pipe the output to a media player and want to kill it while not interrupting the rip. -o file Dump the output to file or use file as a prefix (depending on other settings). Hint: to dump without a prefix use "./". -s suffix Use sfx as a suffix for new files. Hint: the .mp3/.m4a extension is NOT implicit. -t Display song title [metadata] while ripping. -r Remove/don't save partial chunks. This will skip the first chunk and remove the last one upon termination which are (supposedly) incomplete. To use in combination with -m or -E. -q file Append "file name" sequence to file. The file name is written upon file completition. This may be used to trigger events and rejoin splitted parts with an external tool without -E. fResync will use this file in the future. -x regex Save only files whose title (NOT filename) matches against this (or one of these) extended regular expressions. Multiple -x can be specified on the command line to form OR conditions. Dump unaffected. Can be combined with -X. -X regex Do NOT save files whose title matches against this extended regular expression. Same semantics as -x. -I file Load include/exclude REs from file. Each line must be prefixed with + or - to indicate whether it's a positive or negative expression (-xX). -f expr Filter titles through the specified coprocessor expression. The raw title is passed to the expression (doesn't include any additional prefixes/suffixes). As the result will be used internally, some limitations apply. Read carefully the Filtering_ section. -F file Filter titles through the specified coprocessor script. Same semantics as -f, but the expressions are loaded from a file instead. Conflicts with -f. -C path Specify the path of the external title rewriting coprocessor. Defaults to "sed". The executable must support the '-e', '-f' flags and operate through stdin/out, like "sed". -M time Maximum recording time. See Notes_. -i time Maximum network idle time. Stops recording after the specified amount of time is passed without network activity. Defaults to 0 (default tcp timeout). -a file Read authentication credentials from file (the file must contain a line of the form user:password). Note that only the Basic HTTP authentication scheme is supported. -l num Redirect follow limit. Defaults to 1. 0 disables redirection entirely. fResync options ~~~~~~~~~~~~~~~ -b By default fResync maps the entire file into memory when operating. However this can create problems on loaded systems with large files or when simulating. This reverts to a buffered I/O mode. This flag is also implicit when simulating. -s Simulate the process. Print on the standard output the starting sync offset and stream length, but don't modify the source file. -v Verbose. -n frames Require/decode at least n valid consecutive frames to validate the sync offset. Defaults to 6. -m len Maximum frame length. Defaults to 1597. fResync uses this value to determine the maximal region of the file to be checked. fPls options ~~~~~~~~~~~~ -P path Specify a different name or full path for the fIcy executable (defaults to "fIcy"). -v Verbose. -R max Specifies the maximal number of retries to do for each stream upon connection/read failure. -L max Specifies the maximal number of loops to do for the entire playlist (-1 for infinite). -T time Wait time to pause after each failure. -M time Maximum cumulative recording time. See Notes_. -i time Maximum network idle time. Same as fIcy's when loading a playlist via http. Forwarded to fIcy. -a file Read authentication credentials from file. Same as fIcy's when loading a playlist via http. The credentials are automatically forwarded to fIcy, but you can override them when needed. -l num Redirect follow limit. Same as fIcy's when loading a playlist via http. Forwarded to fIcy. -d file Run as a daemon, redirecting messages to file. fIcy's -d option is enforced. As the process is chdir-ed to the root directory you also have to specify absolute paths for all options, including fIcy's ones. Examples ~~~~~~~~ Use fIcy to display ICY titles while playing:: fPls http://example.com:8080/listen.pls -t | mpg123 - Rip a station until stopped:: fPls -L-1 http://netradio.invalid/listen.pls -s.mp3 -o./ -cmrd Connect directly to the stream with server:port and /path:: fIcy -s .mp3 -o ./ -md 123.123.123.123 8080 /path/to/stream Rip an .mp3 stream while playing, but allows the player to be restarted later by using a named fifo (note that you can re/open "fifo" with any player):: $ mkfifo fifo $ fIcy -p ... > fifo $ mpg123 fifo Record your favourite program "XYZ" usually on-air between 16:30-17:00:: at 16:30 fPls -M 30m http://example.com/listen.pls -o program.mp3 -x XYZ ^D Cleanup a ripped and/or damaged mp3 file:: fResync file.mp3 Companion software ------------------ `bfr `_: Audio-oriented rebuffering tool. Ideal for lousy streams. `mpgedit `_: Frame-level mp3 cutting tool. DISCLAIMER ---------- We would like to remind you that saving streams containing copyrighted material without explicit consent is *ILLEGAL*. For stream administrators, please see our statement in the FAQ_. Notes ----- The output files produced by fIcy may miss audio framing information and headers since the separation does not consider the audio data. For this reason, your player 'may' (but should not) fail to reproduce the dump or output some initial noise: this is expected. fResync can be used to cleanup MPEG files after processing. You can also use other tools such as mpgedit for cutting the file in arbitrary positions without diminishing the quality. Assuming that your song spans across three files (use -q to know which ones), that's how to proceed:: cat 1.mp3 2.mp3 3.mp3 > temp.mp3 && xmpgedit temp.mp3 Do *not* resync the files if you're going to post-process them this way: fResync would remove at least one boundary frame on each file, while other tools could also insert extra empty frames to silence the decoder! The -M flag supported by both fIcy and fPls accepts a time specification in seconds, `HH:MM` or `N minutes/hours/days`. Time starts just after the connection has been established, but without counting further delays. Also beware that -M specified in fPls means `cumulative recording time` (time accumulates across retries/timeouts), while -M specified in fIcy means `single stream recording time` (recording stops at the first error or when the specified time has elapsed). Filtering --------- Most online radio stations tend to put banners in the title that will be shown in the player, and eventually result in the filename. To overcome to this (and more), fIcy offers the possibility to rewrite each title through a normal sed script via the "-fF" flags. A real sed coprocess is used along the execution so all of sed's power is available, but some limitations apply: * Each line of input should result in one output line, and ONE ONLY. * Two consecutive identical titles will result in the second one being ignored (thus NOT splitting the stream). Consider this rule, as removing carefully the banner could result in a better separation. * The resulting title will still apply for -xXI as usual. * Please note that the *title* is filtered, not the filename (which may still have some characters removed/modified). Use -tv to see what is actually sent to the filter. You can actually use any executable that works as a stream editor by specifying the path with '-C'. The executable must support the '-e' (inline expression) and '-f' (script file) flags or, at least, ignore them. This allows for any script or custom executable to be used when a "sed" script is considered inadequate. Filtering examples ~~~~~~~~~~~~~~~~~~ As an example, suppose your titles look like this:: Artist - Title (radiobanner) You can write a sed expression or script containing:: s/ (radiobanner)$// to remove the trailing part. This facility can also be used to uniform file names, invert Artist/Title positions and so on. Clever use of the pattern space can also be used to merge albums. sed alone can be used to debug expressions, eg:: echo "test title" | sed -e 'expr' Refer to the sed(1) manual for a complete list of commands you can use. Installation ------------ fIcy comes with a very simple Makefile that should work on any system using gcc, or IRIX. GNU make or pmake is required. Documentation is generated from these files using rst2html_. If you need to use a different compiler (for example on OpenBSD), you can call make as follows:: CXX="eg++" make -e instead of changing manually the Makefile. Please note that, when using gcc, at least g++ >= 3 is required to compile fIcy. There's no "make install" target. Instead you should copy the generated executables into the final path, usually doing: cp fIcy fPls fResync /usr/local/bin Also note that, for "fPls" to work, fIcy must be already installed (be in "PATH") or a full fIcy path must be specified with -P. .. _rst2html: http://docutils.sourceforge.net/ General/support mailing list ---------------------------- If you feel to discuss improvements and suggestions, and/or test beta releases before announcement you can subscribe to `ficy-users` by either sending an empty email to , using GMane_ (group "gmane.comp.audio.ficy.users") or by contacting the author at .

Yes, as explained in the README, there's no data loss. Which audio formats fIcy supports? fIcy itself is not limited to any audio format, only to the transport used. For this reason fIcy can work transparently on MPEG1/Layer3, MPEG2/4 audio streams (usually called MP3/MP2/MP4 AAC). OGG is supported but, as titles are encoded in the OGG stream itself, track separation doesn't work. fResync only understands MPEG1 files. Why not separate tracks on silence points? Short answer: nonsense. Long answer: silence detection would require full data decoding, would require reliable metaint positions and indeed would require real silence between tracks. When cross-fading/mixing is used, silence detection is just a waste of computing resource. On streams where silence between tracks *does* exist, metadata alone will do the work almost as well. Where metaint positions are useless, silence detection would be useless as well. We believe separation done that way is a lost war from the beginning. Why not write MPEG tracks on frame boundaries directly? Maybe in a future release. Can you insert id3/v2 tags in the files automagically? Several tools already exists for this. If you're really sure about adding tags, you may want to resync the files first as well. How can I resync-and-tag files automatically as they're written? If you're really sure, you can do this by using the file produced by -q. A poor-man's solution could look like this:: $ fIcy -q foo ... & $ tail -f foo | (while read file; do fResync "$file"; [your \ tagging command here]; done) & Is there any plan for a Windows port? No. Don't ask for it. How I can write to a single enormous file? Use the -o flag alone, without -m or -E:: fIcy -o file ... How I can append to a single file? You can use the standard output instead of a named file:: fIcy ... >> file fIcy aborts with "requested metadata, but got nothing" The stream runs without metadata (ie titles). No separation can take place. You can still write huge file chunks without the -mE flags. How I can prevent fIcy to rip my station? Short answer: you can't. Long answer: if your streaming server supports this, you can block on the user-agent. fIcy uses "fIcy [version]" by default, and, contrarily to most other software, offers no way of changing it. Consider however that any user with a minimal amount of brain will be able to change it anyway. A more realistic solution is to disable metadata (ie titles) on your stream, but even then it won't prevent people for saving it on large chunks, and/or use ANY other software like winamp, xmms, wget, telnet, netcat, curl (or even your browser of choice).
