mfgen.pl - a Perl script to generate makefiles to encode audio to different formats.
|
||||||
|
(C)2006-2011, Dan Ponte <amigan@gmail.com>
|
||||||
|
|
||||||
|
Rationale:
|
||||||
|
Generating makefiles allows you to use make -j, which allows you to utilize multiple CPUs in an SMP configuration to
|
||||||
|
encode more than one file at once.
|
||||||
|
|
||||||
|
Help:
|
||||||
|
|
||||||
|
usage: mfgen.pl [-hmMOR] [-y year] [-g genre] [-A artist] [-L album] [-d disc#] [-p path]
|
||||||
|
|
||||||
|
-h : this help
|
||||||
|
-m : album is part multi disc set (writes disc in filename)
|
||||||
|
-y year : set year for album
|
||||||
|
-g genre : set genre for album
|
||||||
|
-A artist : set artist for album
|
||||||
|
-L album : set title of album
|
||||||
|
-d disc# : set disc number (default 1)
|
||||||
|
-p path : path prefix (where to put output files)
|
||||||
|
-M : generate MP3s (must be used with -O for MP3 and vorbis)
|
||||||
|
-O : generate Ogg Vorbis
|
||||||
|
-F : generate FLAC (must be used with -O for FLAC and vorbis, or -M)
|
||||||
|
-R : Rename (actually copy) and tag MP3 (see above notes)
