I would need some help from the video pro's around here.
Story is:
Curious beast that I am I figured I try and see what difference if any the Intel compiler (ICC) makes versus GCC.
Installed Gentoo on a VM (Virtualbox) and compiled everything that would compile with ICC and then encoded a video with the command:
time mencoder a.mpg -ovc xvid -xvidencopts bitrate=-50000: pass=2 -nosound -o a.avi
I did run the first and second pass with the VM and the host repectively but there was not much difference in the first pass.
The second pass did this:
Gentoo with ICC in VM
real 1m6.512s
user 0m15.470s
sys 0m47.800s
Debian host
real 2m8.984s
user 2m7.716s
sys 0m1.180s
Needless to say that I was slightly shocked.
Since I don't know how the xvid codec is build for Debian I tried to compile it in the VM with various options including for a i386 cpu but didn't explain the huge difference.
Mencoder can't be it either since that didn't compile with ICC.
Xvid is the same version on both systems.
Could it be related to the fact that the Debian host is a 64 bit system and the VM guest runs 32 bit?
Dazed and confused
