[vlc] Latency reduction

[Benjamin Molina]

Hello,

I', trying to reduce as much as possible the perceived
latency while streaming. I use the following command
with vlc 0.8.1
./vlc -vvv
v4l:/dev/video0:norm=pal:size=320x240:channel=1 --sout
'#duplicate{dst=display,dst="transcode{vcodec=mp4v,vb=128}:standard{access=udp,mux=ts,url=127.0.0.1:2001}"}'
--noaudio --sout-udp-caching 1 --v4l-caching 1

The incurred latency is about 1 second, and the
udp-caching and v4l-caching (both in server and
client) command do not seem to change  this.
On the contrary, vls (the old videolan server) can
transmit with a very reduced latency (about 200 ms).
It seems the delay is determined by the transcode
module. 
Is it possible to change this latency?
Does it require any configuration change or ,per
contrary, acting directly in the code? In the last
case, what must I change to get a lightweight server?

Thanks in advance,
Benjamin
