On the new version of VLC(.7), I'm seeing a pretty significant CPU usage boost as compared to .62 with MP3s. Specs are as follows:
12" PowerBook(Rev. A)
867mhz PPC G4
640MB RAM
MacOS X 10.3.2 "Panther"
When playing a test MP3(a song encoded at 160Kb/sec) under VLC .62, VLC would eat approximately 7% of the CPU throughout the entire song. VLC .7 on the other hand, is eating ~2.5x that amount, averaging 17% on the same file. All settings appear to be the same between the players(I had though at 1 time this was related to headphone spatialization, but that setting has a negligible effect on CPU usage), so there is no explainable reason on why VLC is using so much additional CPU time all of a sudden, leaving me clueless at this point.
