VideoLAN is a complete software solution for video streaming, developed by students at the Ecole Centrale Paris and contributors from all over the world, under the General Public License (GPL). It has been designed for streaming MPEG 1 and MPEG 2 videos on local area networks (LAN), but it can be extended to metropolitan or wide area networks (MAN, WAN), thanks to the multicast technology.
The VideoLAN solution includes a server, which can stream video from various sources (file, DVD, satellite and MPEG 2 encoder), a client, which can receive, decode and display MPEG 1 and MPEG 2 streams and, if necessary, a channel server which tells automatically to the client the parameters needed to receive the stream.
Here is an illustration of the complete VideoLAN solution :
DVD --->- Unicast/Broadcast/Multicast \ --- File --->-- -------- / \ -------- |->-| Server |=====>====| LAN |---->-----| Client | Satellite ->-- | (VLS) | \ / | (VLC) | / -------- --- -------- MPEG2 -->- ^ encoder | v ---------------- | Channel Server | | (VLCS) | ----------------More details about the project can be found on the VideoLAN Web site.
This Howto is designed to explain how to use the complete VideoLAN solution. It presents the different possibilities of VideoLAN and which configuration you should adopt depending on the configuration of your network.

Basic skills on Linux and Network should be enough.
The VideoLAN Client (
vlc) works on many platforms : Linux, Windows,
Mac OS X, BeOS, *BSD, Solaris, iPaq, QNX. It can read MPEG 1, MPEG 2 and
MPEG 4 / DivX files from a hard disk or a CD-ROM drive, read DVDs and
VCDs. But the most important function is that it can read MPEG 1, MPEG 2
and DVDs streamed on a network. vlc requires at least a Pentium 400Mhz
with 32MB of RAM.
The VideoLAN Server (
vls) can read videos from :
and stream it on the network.
A Pentium 100 MHz with 32 MB of memory should be enough to send one stream on the network. When streaming a lot of videos stored on a hard drive, the actual limitation is not the processor but the hard drive and the network connection.
vls works under Linux, Solaris and Windows. Currently, the Windows
vls version of is only able to stream a video from a file.
The VideoLAN mini-Server (
vlms) is only capable of streaming an MPEG
vlms works on Linux only. It is easier to install and configure
vls and should be used mainly for testing purposes.
vlms can stream MPEG 1 or MPEG 2 files that meet two
vlmscan't stream MPEG ES (Elementary Stream), i.e. a file with only audio or video. In order to know if an MPEG file is MPEG PS, MPEG TS or MPEG ES, read the file with
vlcand look at the messages (with the interface : Click on "View" and "Messages", or use the command line "vlc -v") and look for a line :
If XX = ps or XX = ts, then your file is MPEG PS and MPEG TS respectively , and you may be able to stream it. If XX = es, then your file is MPEG ES and is not streamable.
module: locking demux module `mpeg_XX'
.vobextension are normally MPEG 2 files and files with
.mpegextension or usually MPEG 1 files.
You can download this streamable MPEG 2 PS file for your tests : ftp://ftp.videolan.org/pub/videolan/streams/presentation/presentation_short.vob.
The VideoLAN Channel Server (
vlcs) is the central architecture that
manages the network. There are different versions of vlcs for different
kinds of networks. For example, if your network supports multicast,
you will use
mini-vlcs. If your network doesn't support
multicast but supports VLANs, you should use
mini VLAN Server.
vlcs works on Linux only.
You will need a network, which can be as small as one ethernet 10 / 100 Mbit/s switch or hub, and as big as the whole Internet ! See if your network supports "multicast". The bandwidth needed is :
