Package: ffmpeg-free
Version: 0.svn20080206-8
Severity: minor

hi

following mplayer bug 489411, I was looking to see if FFmpeg may be
optimized more; so I noted that the current gcc command line is quite
messy; e.g. looking into
 http://buildd.debian.org/fetch.cgi?pkg=ffmpeg-free;ver=0.svn20080206-8;arch=alpha;stamp=1212572490
inside the line of  gcc for compiling motion_est.c ,
I count two "-O2" and two "-O3"

(does this make it "-O2.5" ? :-)

Anyway, the same code, when compiled inside MPlayer, was compiled 
with "-O4 -ffast-math -fomit-frame-pointer"

Would it be possible to use the same optimization?

a.
