Comment (by yatahaze):

 Yes thank you. Testing with that now.

 Update on current situation:

 - Running ffmpeg without loudnorm for 1.5 hours: CPU usage started at 16%
 and finished off at 28%... so it is not loudnorm.
 - Running VLC for the same time period: Started at 3% and ended up at
 159%. Wow.

 I have no idea why both ffmpeg and vlc would have the same symptoms. They
 both started rising up at the same time together, which is strange.
 Something fishy is going on...
