Hello, I am using ffmpeg version 1.2. To record (audio/video) my desktop with ffmpeg, I use this command: $ ffmpeg -f x11grab -r 15 -s 640x480 -i :0.0 -f alsa -i default out.mkv Unfortunately, when I am playing this "out.mkv" file on VLC, I can remark that the audio is out of sync. In the console, I can see some warnings: "ALSA buffer xrun". Do you see why ? Thank you.
