So i have a embedded debian board with makes a wlan-accesspoint, controls the car and sends a webcam stream to n900.

I have testet videostream from my laptop webcam to n900 (server and client = vlc) with 3 different ways:

Code:

server rtp:
vlc -vvv v4l2:///dev/video0 --sout '#transcode{vcodec=mp2v,acodec=mpga}:rtp{dst=CLIENTADRESSE,port=5000,sdp=file:///home/andi/sdp.sdp,ttl=10,mux=ts,proto=udp}'

client rtp:
open sdp.sdp file, generated by server
vlc file:///sdp.sdp

Code:

server udp multicast:
vlc -vvv v4l2:///dev/video0 --sout '#transcode{vcodec=mp2v,vb=800,scale=1,acodec=mpga,ab=128,channels=2,samplerate=44100}:std{access=udp,mux=ts,dst=239.255.23.23:1234}'

client:
vlc udp://@239.255.23.23:1234 :udp-caching=0

Code:

server mms stream:
vlc -vvv v4l2:///dev/video0 --sout '#transcode{vcodec=mp2v,vb=64,scale=1,acodec=mpga,ab=8,channels=1}:std{access=mmsh,mux=asfh,dst=:8080}'

client (n900, kmplayer, gstreamer/mplayer):
mms://SERVER:8080
via vlc:
vlc mmsh://SERVER:8080

My problem is, delay between webcam and n900(kmplayer/vlc) is ~2 seconds, thats too long.
Any ideas to decrase this latency?
