Start with replacing mencoder with ffmpeg, it's easy afterwards:

ffmpeg -f x11grab -r 30 -s 640x480 -i $DISPLAY \
	-f pulse -ac 2 -i 1 \
	-c:a libopus -c:v libx264 \
	screencast.mkv

It assumes that you're using X and Pulseaudio.


As far as I can tell there's no "x11grab" equivalent in mencoder.
I could be wrong, though, haven't used the thing for about 10 years or
so.
