[FFserver-user] Not getting audio with x11grab, but seems it should be there

  I am trying to stream a web site from my desktop that has audio. The 
video works just fine, and the codec information shows the following 
audio info when the stream is accessed, but no audio plays:

Decoded    19542 blocks
Played        19540 buffers
Lost                   12 buffers

my ffmpeg/ffserver command is:

ffmpeg -f alsa -ac 2 -i pulse -acodec mp3 -f x11grab -r 30 -s 1280x1024 
-i :0.0 -aspect 4:3 -vcodec libx264 -vpre lossless_ultrafast -threads 0

My ffserver.conf can be viewed here:


The stream is accessed via http://privateip:8090/test1.mpeg, or test2.asf.

Any ideas?
