Anyone knows what's the status on this?
I use the latest build by Celtic Druis and can't get more than 20% CPU on my dual core (MPEG-2 encoding).

If you are only hitting 40% of one core the encoder is not CPU limited at all, are you running into disc IO limitations here?
If you were running into a CPU limited situation, the usage would be at 100% of a single core.

You are right, i verified through Task Manager that both cores are working.
In the meantime i discovered that I have to add "-threads 2" to the ffmpeg command- now it's working fast, utilizing almost 90%.

thanks
