[SOLVED] ncmpcpp media library scrolling lag

thinkpadx61 · 2010-12-03 06:32:16

I'm not sure if this is a problem with ncmpcpp or mpd, but scrolling in the 'library view' in
ncmpcpp is noticeably lagging. Not so bad that it is unusable, but annoying nonetheless.

mpd 0.15.15-2
ncmpcpp-git 20101116-1

# /etc/mpd.conf

music_directory     "~/.mpd/music"
playlist_directory  "~/.mpd/playlists"
db_file               "~/.mpd/db"
log_file              "~/.mpd/mpd.log"
error_file            "~/.mpd/mpd.error"
pid_file              "~/.mpd/mpd.pid"
state_file            "~/.mpd/mpdstate"

user                  "my_username"

audio_output {
    type            "alsa"
    name         "My ALSA Device"
    options      "dev=dmixer"
    device        "plug:dmix"
}

mixer_type      "software"

Which terminal emulator do you use? I had this problem when ncmpcpp was very young and I thought the author and me figured it out, what causes this, but aparently we didn't. I use urxvt. It might help if you try a few different terminal emulators, xterm, *rxvt, ... Maybe it only lags with some of them.

Just a hint, if the problem can't be solved here, don't be too shy to contact the author, he's a super nice guy.

I use rxvt-unicode as my primary terminal emulator, too. In addition, I have tested ncmpcpp in xterm, aterm and fgetty. All with the same
results, unfortunately. I also tried upgrading to mpd-git (20101203-1), with no luck.

I will try to contact the author, though I do suspect the problem lies with mpd. If my memory serves me right, this problem started with the
mpd 0.13 upgrade.

this is possibly a ncmpcpp bug. try to use a socket file, instead of tcp connection. Should be much better.

What exactly do you mean with that?

mpd_host = "/mnt/md0/Audio/.mpd/socket"

Thank you very much, Rasi! That did it. Finally, scrolling is smooth again.

Great stuff, this really helps! Thanks Rasi!
Unfortunately, now mpc needs some extra parameters.

echo "export MPD_HOST=/path/to/mpd_socket" >> ~/.bashrc - but you dont need to, because:
you can set both tcp and socket file addresses in mpd.conf, simply duplicate the line and tweak it to your likings
