ffmpeg screen record

[javaguy]

Like the title says. Sorry if this is a newbie question.

 

ffmpeg -f x11grab -r 30 -s 1280x1024 -i :0.0 -f alsa -i hw:1,1 -ac 2 screenrecord.avi

 

This records screenrecord.avi, and it looks good, but there's no sound.

 

I tried hw:0,0 (that was the first way I tried it) and got an error message.

 

aplay -l

gives me this:

 

**** List of PLAYBACK Hardware Devices ****

What I'd really like is to be able to do a screencast that captures all the application sounds and mic input, but just the app sounds would be awesome.

 

Any suggestions?

 

Thanks!
