I have a Rapberry Pi (model B), wired connected on network.

I want to stream using raspistill and save loop jpeg picture into a fifo file. In the other side I want to read this fifo file with VLC, and display it.

I tried somthing like this: 

mkfifo fifo
wget -O /home/pi/fifo http://192.168.1.27:8554 & omxplayer -r /home/pi/fifo

and this:

cvlc --rc-host 192.168.1.27:8554 /home/pi/fifo -d

to read localy the stream (networkless) I tryed:

cvlc < fifo

(rpi and PC are both on linux)

(I already stream without fifo on VLC player)

Any ideas?

fifos are not for saving or reading more than once. You may find tee better suited to your goals.

Untested guess at what you want(split a network stream):

mkfifo myfifo1 myfifo2 && curl -s http://192.168.1.27:8554 | tee myfifo1 > myfifo2;

Other guess at what you want(display and save on rpi):

raspistill --fullpreview --output - >> jpgs.dat

or using more than one file in a loop 

raspistill --fullpreview --output $(date +%Y%M%dT%H%m%S).jpg

or using raspivid

raspivid -fps 2 --timeout 0 --fullscreen --output $(date +%Y%M%dT%H%m%S).h264

Note that you can set the fps on raspivid and with it's temporal compression it may be better than looping raspistill in some conditions.
