Well, the default flags for mplayer resulting from rebuilding the debianmm packages are -O2 and some -B flag. > > I could reverse this flag now; but note that > this flag affects the code of MPlayer itself, not the code in > the FFmpeg external libraries (that are out of my reach), > and AFAIK that code is much more relevant to speed. > > The set of flags for compiling ffmpeg is quite messy currently; > in one single line of gcc in > > http://buildd.debian.org/fetch.cgi?pkg=ffmpeg-free;ver=0.svn20080206-8;arch=alpha;stamp=1212572490 > I count 4 "-g", two "-O2" and two "-O3" > (does this make it "-O2.5" ? :-) > Yes, this would be more likely the problem. The ffmpeg code is used much more during playback than the mplayer code.

I should prepare for Ubuntu following the Debian breakage. Anyway, their current packages seem unusually slow as well ..
