[Ffmpeg-devel] ffmpeg on Dual-Cores

Is there a way to force ffmpeg to use 100% cpu power on dual-core systems? I tried passing the argument -threads 2 but the maximum usage won't go above 67%.
Here's the command line I use:
ffmpeg -i inputFile -r 25 -qscale 6 -s 320x240 -vcodec mpeg4 -flags trell+4mv+aic -mbd 2 -cmp 2 -subcmp 2 -nr 100 -ab 96 -threads 2 outputFile

I tried also, but same results:
ffmpeg -threads 2 -i inputFile -r 25 -qscale 6 -s 320x240 -vcodec mpeg4 -flags trell+4mv+aic -mbd 2 -cmp 2 -subcmp 2 -nr 100 -ab 96 -threads 2 outputFile

Am I doing something wrong or there's no way I can achieve my goal?

Thank you.
