I was looking for a way to record audio with video on Gnome Shell (Ubuntu 13.04) and after doing these command:
gsettings set org.gnome.shell.recorder pipeline "queue ! videorate ! vp8enc quality=10 speed=2 ! mux. pulsesrc ! audio/x-raw-int ! queue ! audioconvert ! vorbisenc ! mux. webmmux name=mux"
Recording stopped working. I found this solution here.
Any help would be nice.
