Can modify default jukebox transcoding

Hi! I finally found that the transcoding of the jukebox player is defined as a variable (DEFAULT_JUKEBOX_COMMAND) in SettingsService.java. I think it would be nice to be able to edit this command, to add things to the ffmpeg transcoding like ReplayGain (via -af volume=replaygain=track) or redirecting the stream to a pipe instead of redirecting to stdout, as you can do with other players that are transcoding-configurable. Thanks in advance.
