As much as possible, I want to use ffmpeg for all my audio / video needs 
so while watching stuff on:


- which I think are basically Flash videos, I have tried:

   ffmpeg -f alsa -ac 2 -i hw:1 -f video4linux2 -f x11grab -framerate 25 
-i :0.0 ./out.mpg

which gets the video OK but only gets my heavy breathing into the mic on 
my headset - I presume there is some way of capturing the audio that is 
coming out of the computer?
