[FFmpeg-user] Capturing Video/Audio for Screen Casting

[Grad Vector]

Hello Everyone,

I'm running Linux Fedora 18 and I'm trying to capture both audio and video as I'm playing an mp4 file on the Linux Totem player. I could capture the video but I get no audio.  The ffmpeg command that I'm using is:

ffmpeg  -f alsa  -ac 2  -i pulse  -f x11grab
-r 30  -b:v 6000k  -acodec pcm_s16le
-vcodec huffyuv  -preset ultrafast
-threads 2  -ss 2  -t 15  outfile.avi

Does anyone have any suggestions on how I could also capture the audio?
Thanks very much for your help.
