I wrote a http web server component in c++ (using the Qt libraries. Qt is 
needed) for send stream. I use this component for exchange data between server 
and clients and for send stream.

mjpg: 0 seconds
msmpeg4: 1 - 2 seconds
mpeg4: 3 - 5 seconds.
h264: 5 - 8 seconds.

h264 is the best in compression but not for latency.
If you want you can try my application (You can find it in my website, its name 
is DomusBoss) for test the different solutions.
