What exactly have you tried, and what doesn't work?
On your PC:
suppose it's IP = 192.168.1.20 and that you want to receive the video stream on port 56789.
1) Open port 56789 in the firewall.
2) listen with nc on port 56789 and pipe to mplayer
nc -k -l 56789 | mplayer -fps 31 -cache 4096 - # note the dash at the end: it tells mplayer to read from stdin.
On the RPi:
1) Enable camera like this:

2) stream with raspivid:
raspivid -t 0 -o - -w 320 -h 240 | nc 192.168.1.20 56789
I get some 10-20 seconds latency this way, which is unacceptable. This post claims to obtain <1 second latency:

I wonder if RPi 2 has the same latency. Does anyone know?
