Bug#486837: vlc: causes lots of unneccessary interrupts

[Daniel Skorka]

Package: vlc
Version: 0.8.6-svn20061012.debian-5.1+etch2
Severity: minor


wxvlc will cause about 260 interrupts per second when playing a local
MP3 file, about 320 interrupts / second when paused while playing and about
130 ips after being stopped (all values measured using powertop). strace
reveals that wxvlc is constantly calling settimeofday and polling two
file descriptors even when there is nothing to do. This way of keeping the CPU
busy will increase power consumption and temperature, along with drastically
decreasing battery time for laptops.
