I've been experimenting crashes when trying to encode using x264 or lavc
h264, this happens on a p4 and not on a amd tb k7, this is strange
because the code seams to be mmx.
The build is on mingw but I don't known if it's really win32 only.
I don't known too much mmx so I'm not able to locate the code in the
source, but I have trapped the crash with ollydbg so I have some (maybe)
usefull infos.
The code where it crashes is here:

Using x264 or lavc h264 crashes mencoder in the same place
Any clue?
