[emms-help] EMMS and MusicPD

[David Engster]

I recently switched to EMMS and so far I'm pretty happy with it. Thanks
a lot to all involved with this nice package!

I primarily want to use EMMS as a mpd-client, using emms-player-mpd. I'd
also like to let mpd do the extraction of the metadata, with EMMS always
using the information it gets from mpd. Currently, when I
add/modify/delete files, I call emms-player-mpd-update-all and then
emms-cache-set-from-mpd-all. This is working, but the latter function
does not clear the cache beforehand, which is often problematic when I
changed or removed files. Also, I don't want to call two functions after
every change, but I cannot just put them in one function since
'e-p-m-update-all' is running asynchronously.

So I wrote some stuff to do this and attached it to this mail. Maybe
this can be integrated into emms-player-mpd.el? I think it would be
useful for other, too.

I also attached another small patch regarding the syncing of the EMMS
and mpd playlist. The problem here is that I sometimes have playlists
with music and video files, and EMMS tries to insert the video files
into the mpd playlist, which of course causes an error. My patch adds a
check before adding files to the mpd playlist.

Regards,
David
