[MPlayer-users] Mencoder segfaults on new CPU

[Jörg-Oliver Todamm]

Ok, now I use an other web-mailer. Hope it works this time. Sorry for the 
annoyance.

Hello,

I play around with mencoder for about a week now and really like it. But now 
mencoder does not work anymore. Maybe some (arpi) can help me out.

Recently I changes my CPU from iPII-350MHz ro iPIII-700MHz and added some 
extra memory. The system running SuSE Linux 7.2 is acting well and VDR is 
also working flawless.

Whenever I try to use the old mencoder (compiled with iPII and seems only to 
use MMX) or a new compiled one (used CVS from today) mencoder always 
segfaults.

I also tried to vary parameters and so on. Now I am going to recompile LAME 
and MAD.

Configured with --with-extraincdir=/path-to-DVB --enable-longfiles

Here is the output of mencoder (cvs about 1 week old)

With the new CVS I found that CPU detection of mp3lib switches from MMXEXT 
to SSE.
