Instead, it has documentation in HTML +format; see below. +.SH "OPTIONS" +.PP +A summary of options is included below. For a complete +description, see the HTML documentation. +.SS "GENERIC OPTIONS" +.TP +\fB-H \fR +Show detailed help screen +.TP +\fB-d \fR +Decode (default behavior is encode) +.TP +\fB-c \fR +Encode from standard input, or decode to +standard output +.TP +\fB-t \fR +Test a flac encoded file (same as -d +except no decoded file is written) +.TP +\fB-a \fR +Analyze a flac encoded file (same as -d +except an analysis file is written) +.TP +\fB-s \fR +Silent mode (do not write runtime +encode/decode statistics to stdout) +.TP +\fB-o \fIfilename\fB\fR +Force the output file name (usually flac just +changes the extension). May only be used when +encoding a single file. May not be used in +conjunction with --output-prefix. +.TP +\fB--output-prefix \fIstring\fB\fR +Prefix each output file name with the given +string. This can be useful for encoding/decoding +files to a different directory. Make sure if your +string is a path name that it ends with a trailing +`/' (slash). +.TP +\fB--delete-input-file \fR +Automatically delete the input file after a +successful encode or decode. If there was an +error (including a verify error) the input file +is left intact. +.TP +\fB--skip \fIsamples\fB\fR +Skip the specified number of samples at the +beginning of the input file (can be used for both +encoding and decoding) +.SS "ANALYSIS OPTIONS" +.TP +\fB--a-rtext \fR +Includes the residual signal in the analysis +file. This will make the file very big, much +larger than even the decoded file. +.TP +\fB--a-rgp \fR +Generates a gnuplot file for every subframe; +each file will contain the residual distribution +of the subframe. This will create a lot of +files. +.SS "DECODING OPTIONS" +.TP +\fB-F \fR +By default flac stops decoding with an error +and removes the partially decoded file if it +encounters a bitstream error. With -F, errors are +still printed but flac will continue decoding to +completion. Note that errors may cause the decoded +audio to be missing some samples or have silent +sections. +.SS "ENCODING OPTIONS" +.TP +\fB--ogg\fR +When encoding, generate Ogg-FLAC output instead +of native-FLAC. Ogg-FLAC streams are FLAC streams +wrapped in an Ogg transport layer. The resulting +file should have an '.ogg' extension and will still +be decodable by flac. + +When decoding, force the input to be treated as +Ogg-FLAC. This is useful when piping input from +stdin or when the filename does not end in '.ogg'. +.TP +\fB--lax\fR +Allow encoder to generate non-Subset +files. +.TP +\fB--sector-align\fR +Align encoding of multiple CD format WAVE +files on sector boundaries. See the HTML +documentation for more information. +.TP +\fB-S \fI{ # | X | #x }\fB\fR +Include a point or points in a SEEKTABLE. Using #, +a seek point at that sample number is added. Using +X, a placeholder point is added at the end of a the +table. Using #x, # evenly spaced seek points will +be added, the first being at sample 0. You may use +many -S options; the resulting SEEKTABLE will be the +unique-ified union of all such values. With no -S +options, flac defaults to '-S 100x'. Use -S- for +no SEEKTABLE. Note: '-S #x' will not work if the +encoder can't determine the input size before +starting. Note: if you use '-S #' and # is >= +samples in the input, there will be either no seek +point entered (if the input size is determinable +before encoding starts) or a placeholder point (if +input size is not determinable). +.TP +\fB-P \fIbytes\fB\fR +Tell the encoder to write a PADDING metadata +block of the given length (in bytes) after the +STREAMINFO block. This is useful if you plan to +tag the file later with an APPLICATION block; +instead of having to rewrite the entire file later +just to insert your block, you can write directly +over the PADDING block. Note that the total length +of the PADDING block will be 4 bytes longer than +the length given because of the 4 metadata block +header bytes. You can force no PADDING block at +all to be written with -P-, which is the default. +.TP +\fB-b \fIblocksize\fB\fR +Default is 1152 for -l 0, else 4608; must be +192/576/1152/2304/4608/256/512/1024/2048/4096/8192/16384/32768 +(unless --lax is used) +.TP +\fB-m\fR +Try mid-side coding for each frame (stereo +input only) +.TP +\fB-M\fR +Loose mid-side coding for all frames (stereo +input only) +.TP +\fB-0..-8\fR +Fastest compression..highest compression +(default is -5). These are synonyms for other +options: +.RS +.TP +\fB-0\fR +Synonymous with -l 0 -b 1152 -r 2,2 +.TP +\fB-1\fR +Synonymous with -l 0 -b 1152 -M -r 2,2 +.TP +\fB-2\fR +Synonymous with -l 0 -b 1152 -m -r 3 +.TP +\fB-3\fR +Synonymous with -l 6 -b 4608 -r 3,3 +.TP +\fB-4\fR +Synonymous with -l 8 -b 4608 -M -r 3,3 +.TP +\fB-5\fR +Synonymous with -l 8 -b 4608 -m -r 3,3 +.TP +\fB-6\fR +Synonymous with -l 8 -b 4608 -m -r 4 +.TP +\fB-7\fR +Synonymous with -l 8 -b 4608 -m -e -r 6 +.TP +\fB-8\fR +Synonymous with -l 12 -b 4608 -m -e -r 6 +.RE +.TP +\fB--fast\fR +Fastest compression. Currently +synonymous with -0. +.TP +\fB--best\fR +Highest compression. Currently +synonymous with -8. +.TP +\fB-e\fR +Do exhaustive model search +(expensive!) +.TP +\fB-E\fR +Do escape coding in the entropy coder. This +causes the encoder to use an unencoded representation +of the residual in a partition if it is smaller. It +increases the runtime and usually results in an +improvement of less than 1%. +.TP +\fB-l \fImax_lpc_order\fB\fR +0 => use only fixed predictors +.TP +\fB-p\fR +Do exhaustive search of LP coefficient +quantization (expensive!). Overrides -q, +does nothing if using -l 0 +.TP +\fB-q \fIbits\fB\fR +Precision of the quantized linear-predictor +coefficients, 0 => let encoder decide (min is 5, +default is 0) +.TP +\fB-r \fI[level,]level\fB\fR +Set the [min,]max residual partition order +(0..16). min defaults to 0 if unspecified. Default +is -r 3,3. +.TP +\fB-V\fR +Verify a correct encoding by decoding the +output in parallel and comparing to the +original +.TP +\fB-F- -S- -P- -m- -M- -e- -E- -p- -V- --delete-input-file- --lax- --ogg- \fR +These flags can be used to invert the sense +of the corresponding normal option. +.SS "FORMAT OPTIONS" +.TP +\fB-fb\fR +Big-endian byte order +.TP +\fB-fl\fR +Little-endian byte order +.TP +\fB-fc \fIchannels\fB\fR +Set number of channels. +.TP +\fB-fp \fIbits_per_sample\fB\fR +Set bits per sample. +.TP +\fB-fs \fIsample_rate\fB\fR +Set sample rate (in Hz). +.TP +\fB-fu\fR +Unsigned samples (default is signed) +.TP +\fB-fr\fR +Force to raw format (even if filename ends +in \fI.wav\fR). +.SH "SEE ALSO" +.PP +The programs are documented fully by HTML format +documentation, available in +\fI/usr/share/doc/flac/html\fR on +Debian GNU/Linux systems. +.SH "AUTHOR" +.PP +This manual page was written by Matt Zimmerman for +the Debian GNU/Linux system (but may be used by others). -- cgit v1.2.1
