1912	mpeg2video cpu usage bottleneck	darkbit		"I tried to narrow it down as much as possible to ffmpeg so here is my log:
I noticed on my quad core machine that ffmpeg would not use more than 50% on each core.

#First I created a ramdisk with lilo using append="" ramdisk_size=4194304""
#On fstab I added the line:
/dev/ram0 /ram tmpfs defaults 1 2

#then ran lilo
#created the /ram directory

#after the reboot with the ram disk I clocked up my cpu to its full clock of 1600Mhz per core, using cpufreq-set.
