raspberry pi video streaming via vlc and raspivid
http://www.mybigideas.co.uk/RPi/RPiCamera/
The first example seems to work. The second one not so well.
Here I'm documenting how to stream from the Raspberry Pi Camera board using VLC. Most of this is covered in the Raspberry Pi forums in this thread.
The camera needs to be setup using the various instructions on the Raspberry Pi website and the only additional software package that needs to be installed is VLC which can be installed by doing sudo apt-get install vlc with further details about it on the VideoLan website.
The most reliable streaming method seems to be via RTSP and the command line to launch it is.
RTSP works well on a local network, but can be hard to expose through a router to allowing streaming over the internet. To over come this VLC can be configured to stream via HTTP, this seems to use a bit more CPU on the Raspberry Pi and can suffer from dropped frames however it only uses one port and can be easily port forwarded through most standard routers. The command for this configuration is
One final way of streaming the video is over HLS (HTTP Live Streaming). This, apparently, allows the video to be easily streamed to iOS devices. For this to work a web server needs to be installed on the Raspberry Pi. A popular choice is apache that can be installed using sudo apt-get install apache which will then serve the files stored in /var/www. To setup VLC to generate the HLS stream you can run
(Remembering to correctly set the IP address of your Raspberry Pi). Again this can be played back using VLC by opening a Network Stream of http://<IPofRaspberryPi>/streaming/stream.m3u8 however HLS can consume all the CPU on the Raspberry Pi

raspivid -o - -t 9999999 |cvlc -vvv stream:///dev/stdin --sout '#rtp{sdp=rtsp://:8554/}' :demux=h264This causes the video from the camera to be streamed from port 8554 of your Raspberry Pi. This can then be viewed by launching VLC on your PC and open a 'Network Stream' with the addressrtsp://<IPofRaspberryPi>:8554/
