Bug#470903: vlc: Heavy CPU usage when running in daemon mode with remote control interface

[David]

Package: vlc
Version: 0.8.6.c-6
Severity: normal

Running VLC on my system (with a bunch of low quality FLVs downloaded
from YouTube) usually uses less than 10% CPU (in 'top' listing). But
when I run VLC with in Daemon mode with Remote Control interface
enabled, the CPU usage is over 90%.

Here is my command-line:

/usr/bin/vlc -L -I rc --rc-fake-tty --rc-show-pos --no-video-deco \
  --video-x 0 --video-y 0 --width 1024 --height 768 -v3 \
  -d --file-logging --logfile /tmp/vlc.log \
  --volume 450 --aout alsa /home/david/NO_BACKUP/downloads/youtube/

If I remove either the daemon mode "-d" or the remote control
"rc --rc-fake-tty --rc-show-pos" options then the CPU usage
is low. It's only when both sets of options are used that the
CPU usage is hight.

I am running KDE 5:48 (4:3.5.5) under X.Org 1:7.2-5 on Debian
Testing. The problem also occurs with IceWM on Debian
Etch systems.
