Screencast recording under Ubuntu
Noted for future reference:
avconv -strict experimental -f x11grab -r 25 -s 1024x768 \
-i :0.0 -pre medium -f alsa -ac 2 -ar 22050 -i pulse \
cast.webm
I’ll have to decipher that myself some time, but for now it’s good enough to make note of it as I may need to do something like that at some point in the future.
