https://answers.launchpad.net/yade/+question/294631

Hello, I was learning how to record a ' mpeg'  file trying the tutorial's script 2.6.5 (Yade Documentation) but the script was returning the error below. It seems that makeVideo is not working. Can someone please help? I'm using Yade 1.20.0-151-0ecfcd0~trusty version.
