Transcoding in Madsonic is a way to re-encode music on the fly to a format
|
|
your listening device supports. A common use is transcoding FLAC, WMA,
|
|
and Vorbis audio to MP3 for devices supporting only that codec.
|
|
|
|
Configuring transcoding uses up to three commands one would use on a normal
|
|
command line pipe but with a whitelist of executables installed or linked into
|
|
%%MADSONIC_HOME%%/transcode. The transcoding configuration page takes
|
|
transcoding rules in the form of:
|
|
|
|
[rule name] [convert from] [convert to] [command 1] [command 2] [command 3]
|
|
|
|
The most compatible single audio transcoding command is with FFmpeg, transcoding
|
|
any input to MP3, mapping all streams to output, and limiting metadata to the
|
|
more-compatible ID3v2.3:
|
|
|
|
[All to MP3] [ogg flac wma aiff m4a] [mp3] ...
|
|
[ffmpeg -i %s -ab %bk -id3v2_version 3 -map_metadata 0 -map 0:0 -ar 44100 -ac 2 -v 0 -f mp3 -]
|
|
|
|
You can also transcode with multiple single-codec commands to avoid
|
|
the heavy FFmpeg dependency:
|
|
|
|
[FLAC to MP3] [flac] [mp3] ...
|
|
[flac --silent --decode --stdout %s] [lame --silent -h -b %b -]
|
|
|
|
[AAC to MP3] [m4a] [mp3] ...
|
|
[faad -s -o - %s] [lame --silent -h -b %b -]
|
|
|
|
[Vorbis to MP3] [ogg] [mp3] ...
|
|
[oggdec -Q -o /dev/stdout %s] [lame --silent -h -b %b -]
|
|
|
|
[MPC to MP3] [mpc] [mp3] ...
|
|
[mpcdec %s -] [lame --silent -h -b %b -]
|
|
|
|
[APE to MP3] [ape] [mp3] ...
|
|
[mac %s - -d] [lame --silent -h -b %b -]
|
|
|
|
[Trackers to MP3] [mod s3m xm it] [mp3] ...
|
|
[xmp -q -c %s] [lame --silent -h -b %b -]
