Can I use an alternate transcoder in jukebox mode?

[chasmo]

When I used 4.5, I achieved replaygain on the jukebox by using a transcoder like this:

ffmpeg [blah blah] %s -flac - | flac --decode --apply-replaygain-which-is-not-lossless=0tln1 - - | lame --decode - -

Now that I've upgraded to 4.9, it looks like the jukebox has been changed to always use the internal ffmpeg to au conversion, even if you have other conversions specified in the jukebox player setup.

Anyone know how to change this in the code? I'd really like replaygain again, as I listen to a lot of random playlists.

Thanks.
