[FFmpeg-user] Reduce CPU usage to match VLC

Would like to use ffmpeg instead of VLC for the given task but I can not
seem to reduce the CPU usage.

Here is how I do it in VLC:(~30% CPU usage)

/vlc -vvv --sout '#transcode{venc=x264{preset=

Here is my ffmpeg command: (~120% CPU usage)
./ffmpeg -i <> -vcodec
libx264 -vb 1500k -s 480x320 -acodec libfdk_aac -ab 32k -f flv rtmp:// <>

Quality seems to me somewhat the same but ffmpeg uses 3x more CPU then VLC.
Any idea how I can match VLC cpu usage with ffmpeg?
