But as you can see from the message, something is wrong with the AC3
audio track (output stream #1:0). Have you tried stream-copying input
#0:0 or #0:1 instead of re-encoding it?

By the way, you have two outputs:
out%03d.ts (segment)

and
http://10.125.133.31:8080/feed1.ffm

and you are not specifying any parameters for the second one. Are you
sure this is what you are trying to achieve?

Okay for second output Now i am using tee option and below is the ffmpeg commnad, ffmpeg does not complain this time for incorrect
parameters  but ffserver is not streming data.
