== Introduction ==
The objective of this How To is install setup and stream high resolution, high frame rate video from your Raspberry Pi (with a Camera module) over a network.
Based on [http://www.ics.com/blog/raspberry-pi-camera-module#.VJFhbyvF-b8].

=== Equipment ===
* Raspberry Pi
* Raspberry Pi camera module

=== Initial Setup ===
It is assumed that your Raspberry Pi is running Raspian and that the camera module is connected correctly.
Familiarity with the command line prompt is of benefit as most of the work here is via the command line.
If you're using the desktop, open a Terminal from the desktop menu or use a remote connection via SSH [[Enable SSH#Connect_via_SSH_on_a_Local_network]]

To test the camera is working take a picture from the camera.
<pre>
$ cd ~
$ raspistill -o test_image.jpg
</pre>
To check the picture use the file browser the picture should be in your home folder (~) [http://thepihut.com/blogs/raspberry-pi-tutorials/16021420-how-to-install-use-the-raspberry-pi-camera].

If its not working, try the following,
<pre>
$ sudo apt-get update
$ sudo apt-get upgrade
</pre>
check the camera is enabled
<pre>
$ sudo raspi-config
</pre>
Reboot to bring your pi back up in a known good state and hopefully a retest of the picture capture will work.
<pre>
$ sudo reboot
</pre>

== Streaming ==
=== Install vlc ===
<pre>
$ sudo apt-get install vlc
</pre>
Enable he v4l module
<pre>
sudo modprobe bcm2835-v4l2
</pre>

=== VLC command ===
Use the command line version of vlc to directly stream the camera output to a port.
<pre style="white-space: pre-wrap;
white-space: -moz-pre-wrap;
white-space: -pre-wrap;
white-space: -o-pre-wrap;
word-wrap: break-word;">
cvlc v4l2:///dev/video0 --v4l2-width 640 --v4l2-height 480 --v4l2-chroma h264 --sout '#standard{access=http,mux=ts,dst=0.0.0.0:8085}' &
</pre>

Change the <code>--v4l2-width</code> and <code>--v4l2-height</code> to adjust the screen resolution.
I've tested up to 1900 x 1080.
Change <code>8085</code> to adjust the port to broadcast on.

=== Monitor the Stream ===
Check that this is working by monitoring the stream on anther PC (is best).
We need to know the IP address of your Pi on your network and the port (from above):
<pre>
$ ifconfig | grep 'inet addr:'
</pre>
should give something like
<pre>
inet addr:192.168.0.31 Bcast:192.168.0.255 Mask:255.255.255.0
inet addr:127.0.0.1 Mask:255.0.0.0
</pre>

Point your Firefox browser to the address <code>http://192.168.0.31:8085</code> to see the live feed.
Alternatively use the same address in the VLC GUI under a 'Open Network Stream'.

== Stream Capture ==
It is possible to capture the stream on any computer than can see the stream.
If your router is correctly configured the stream can be viewed by any computer on the internet.
<br />
Use VLC to record the stream (use the figures below as a guide)
# Enter the network stream address
# Select the Convert Save button
# Create a Raw Capture Profile using the
# Select the Raw profile and select the file save location.
