The major functional change here is how files move around when in keep_new
mode. Now, files are first moved to the destination directory and then
copied/transcoded back into the library.
This avoids problems where naming conflicts could occur when transcoding from
MP3 to MP3 (and thus not changing the filename).
@yagebu: I did a code review of the new version of convert using FFmpeg as a
backend. Everything looks perfect. These are just a few changes to the docs.
Thanks again!
Instead of flac and lame the convert plugin now uses ffmpeg. This adds
support for more input formats and simplifies the code. ffmpeg also uses
the lame encoder internally and has equivalents of all the -V<num>
presets which should be sufficient.
