Description:
mplayer randomly causes PC (Pentium III Coppermine) to hang and freeze completely. No log files can be obtained as the PC gets instantly and completely freeze. My video chip is Mach64 (ATI Rage Mobility M1)

I have located the problem at MMX2 detection. My CPU does not show MMX2 nor MMXEXT capabilities in /proc/cpuinfo. However, mplayer does detect MMX2 and uses (a tiny bit of it) for Optimized OnScreenDisplay.

I have modified the mplayer cpudetect.c file so it forces to 0 the MMX2 capability. Then, the problem is corrected and no more PC freezes or hangs ocurr.

I just wanted to tell, as it could also happen to other people out there. It's difficult to track this problem to MMX2 detection.

I also wanted to make a request: maybe one of the following two options could be done to make this easier:
1) correct cpudetect.c so it does not falsely detect MMX2 in a MMX2-less computer as mine.
2) (this is only if point 1 cannot be achieved), create new mplayer parameters to override cpu capabilities detection in runtime, so we could avoid to compile again mplayer to disable a particular cpu capability.

Thank you in advance and best regards. David.
