[FFmpeg-user] recording screen with audio to webm

[3589157 3589157]

Hello. I'm trying to record directly to webm using f.e. this command:


  ffmpeg -f alsa -ac 2 -i pulse -an -f x11grab -r 30 -s 1440x900 -i :0.0
-threads 4 -y 1.webm
But I get only video without a sound(not from microphon nor from internal
sound).
Any ideas?
