Its goal is to automatically rip a stream into user customisable +files. It will work with \s-1ICY\s0 compatible streams, allowing you to either to save +the stream to disk or to pipe the output to a media player, or even both. fIcy, +among other uses, is ideal for batch/unattended recording of radio programs and +stream debugging. +.PP +The fIcy package includes: +.IP "\-" 4 +fIcy itself, a stream separator/multiplexer, +.IP "\-" 4 +fResync, a fast MPEG-resyncing utility, +.IP "\-" 4 +fPls, a playlist frontend for fIcy. +.SH "OPTIONS" +.IX Header "OPTIONS" +.SS "fIcy options" +.IX Subsection "fIcy options" +.Vb 2 +\& \-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\*(Aqt 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\*(Aqs a positive or negative +\& expression (\-xX). +\& +\& \-f expr Filter titles through the specified coprocessor expression. The +\& raw title is passed to the expression (doesn\*(Aqt 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 \*(Aq\-e\*(Aq, \*(Aq\-f\*(Aq +\& 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. +.Ve +.SS "fResync options" +.IX Subsection "fResync options" +.Vb 4 +\& \-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\*(Aqt 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. +.Ve +.SS "fPls options" +.IX Subsection "fPls options" +.Vb 2 +\& \-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\*(Aqs when loading a +\& playlist via http. Forwarded to fIcy. +\& +\& \-a file Read authentication credentials from file.

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 \s-1MPEG\s0 files +after processing. +.PP +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:: +.PP +.Vb 1 +\& cat 1.mp3 2.mp3 3.mp3 > temp.mp3 && xmpgedit temp.mp3 +.Ve +.PP +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! +.PP +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). +.SH "FILTERING" +.IX Header "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 \*(L"\-fF\*(R" flags. A real sed coprocess is used along the execution so +all of sed's power is available, but some limitations apply: +.PP +* Each line of input should result in one output line, and \s-1ONE\s0 \s-1ONLY\s0. +.PP +* Two consecutive identical titles will result in the second one + being ignored (thus \s-1NOT\s0 splitting the stream). Consider this rule, + as removing carefully the banner could result in a better separation. +.PP +* The resulting title will still apply for \-xXI as usual. +.PP +* 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. +.PP +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 \*(L"sed\*(R" script is considered +inadequate. +.SS "Filtering examples" +.IX Subsection "Filtering examples" +As an example, suppose your titles look like this:: +.PP +.Vb 1 +\& Artist \- Title (radiobanner) +.Ve +.PP +You can write a sed expression or script containing:: +.PP +.Vb 1 +\& s/ (radiobanner)$// +.Ve +.PP +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:: +.PP +.Vb 1 +\& echo "test title" | sed \-e \*(Aqexpr\*(Aq +.Ve +.PP +Refer to the \fIsed\fR\|(1) manual for a complete list of commands you can use. +.SH "DISCLAIMER" +.IX Header "DISCLAIMER" +We would like to remind you that saving streams containing copyrighted material +without explicit consent is *ILLEGAL*.
