I am planning on doing some server minecraft screen recording just for fun, and so I've been looking around at what there is to offer. I know FRAPS won't work on Ubuntu and I'd rather not spend the $30 for it anyways, so I looked around and found glc, which I thought looked good.
I then googled some more and found this question: Fraps like programs for Ubuntu? and there are two answers, one suggesting glc (which I knew about), and another suggesting gtk-recordmydesktop (also knew about) and VLC streaming (did not know about).
My question is, which of these would have the least impact on RAM and still record my video at good (minimum 360p) quality and get sound from voice chat through an SIP client on my system (SIP=Session Initiation Protocol - I would be using Jitsi or Empathy) connected to my friend(s) using Skype.
