Simple video streaming with ffserver
From Organic Design wiki
In this example we use the Logitech QuickCam Express web camera to stream video to web page using ffserver
ffserver is part of the ffmpeg package.
apt-get -y install ffmpeg
ffserver creates a network socket that is available from client machines to view the video. Once started, you attach an ffmpeg process to the server to do the encoding. Configuration of ffserver is done via the /etc/ffserver.conf file.
Typical ffserver.conf file
Port 8090
# bind to all IPs aliased or not
BindAddress 0.0.0.0
# max number of simultaneous clients
MaxClients 1000
# max bandwidth per-client (kb/s)
MaxBandwidth 10000
# Suppress that if you want to launch ffserver as a daemon.

To get things going, start the server
ffserver &
Attach the ffmpeg process to do the encoding. This is done via a loopback socket.
ffmpeg -r 25 -s 352x288 -f video4linux -i /dev/video0 http://localhost:8090/feed1.ffm
Parameters are
- -r - rate in frames per second
- -s size in pixels width x height (width must be a multiple of 16) and should match the values in the above config file.
- -f gets input from the video4linux driver
- -i is the v4l device (if this is not present refer to Logitech QuickCam Express)
- Lastly the loopback socket
Now you should be able to browse to the server address (or localhost if it's the same machine) and see some live video.
The name of the file will be as defined in the <Stream> section above.
