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: MPlayer 1.0pre7-3.4.2 (C) 2000-2005 MPlayer Team CPU: Advanced Micro Devices Opteron Sledgehammer (Family: 8, Stepping: 10) Detected cache-line size is 64 bytes MMX supported but disabled MMX2 supported but disabled SSE supported but disabled SSE2 supported but disabled 3DNow supported but disabled 3DNowExt supported but disabled CPUflags: MMX: 0 MMX2: 0 3DNow: 0 3DNow2: 0 SSE: 0 SSE2: 0 Compiled for x86 CPU with extensions: This is with automagic CPU detection compiled in, but when I take it out, I still get the same thing.
