Package: vlc
Version: 0.8.6.h-4+lenny2
Severity: important
vlc in Lenny eats 20-30% more CPU than the previous version on
same hardware. Using a DVD rip of Planet Earth as a test
System | Lenny | Etch
P3/1200 + Nvidia | 50-70% CPU | 30-50%
P3/900 + Trident | 100% CPU, unusable | 70% with some skipping
Geode/1000 + SiS | 70%+ CPU, skips | 30% CPU, works fine
Whatever change there was in-between it is sufficient to push older
systems or various underclocked/fanless systems into the "unusable"
zone.
I tried building 1.00 from unstable with same results. CPU usage is
same as in Lenny.
