Does anyone know why mplayer doesn't seem to acknowledge support of any CPU
flags like SSE, MMX, 3DNow, etc? I've done some digging, but have only come
up with stuff from OpenBSD that didn't make a whole lot of sense to me, and
I'm not sure how applicable it is to FreeBSD (that the flags aren't present
in the machdep sysctl).
The dmesg:
CPU: AMD Opteron(tm) Processor 244 (1808.34-MHz K8-class CPU)
Features=0x78bfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,MMX,FXSR,SSE,SSE2>
AMD Features=0xe0500800<SYSCALL,NX,MMX+,LM,3DNow+,3DNow>
The mplayer output:

This is with automagic CPU detection compiled in, but when I take it out, I
still get the same thing.
