Yes I will send complete configuration, tomorrow (not in this office today).

- need to install yasm package
- need to install many  *-dev packages  (almost everytime you get an 
error when launching "configure", it is because of a missing *-dev package)

Could never get a working mpeg_ts  (get the first image and ....nothing 
more)  nor an ogg  format .
Could never get a working x264 encoding : encoding from ffmpeg to a file 
seems to work, but ffmpeg always crashes down  when sending to ffserver 
(with a message invoking av_interleave and can not open file, as I could 
So I only could get only a working .swf (flv+mp3)  format.

I tested only http.
I had an image freezing after approx 1 hour  (sound was still going 
good)  on the customer (VLC 2.0).

Global delay is approx 7 sec  on a small lan. Would probably be much 
longer (10-15 sec) if the flow has to pass through routers,  and on a 
WAN like internet.

A message for the developpment-team (hoping some guys of the team read 
this m-l) :
I fell very surprised of the so many warning massages sent by the compiler.
- Many variables not initialized,
- Many warnings about casting
