If you are using cpufreq I've found that can hurt perf with ffmpeg/mplayer.
The default threshold is too high, but even lowering it doesn't always
seem to help.
Whenever I play/encode I've taken to just forcing it to perf -
echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
repeat for cpu1 cpu2 etc
to turn back down
