Chapter 1. Streaming, Muxers and Codecs
VideoLAN software
VLC Media Player
VLC works on many platforms: Linux, Windows, Mac OS X, BeOS, *BSD, Solaris, Familiar Linux, Yopy/Linupy and
QNX. It can read:
• MPEG-1, MPEG-2 and MPEG-4 / DivX files from a hard disk, a CD-ROM drive, ...
• DVDs and VCDs
• from a satellite card (DVB-S)
• from a camcorder (DV)
• MPEG-1, MPEG-2 and MPEG-4 streams from the network sent by VLS or VLC’s stream output
VLC can also be used as a server to stream:
• MPEG-1, MPEG-2 and MPEG-4 / DivX files,
• DVDs,
• from an MPEG encoding card,
• from a camcorder DV,
to:
• one machine (i.e. to one IP address): this is called unicast,
• a dynamic group of machines that the clients can join or leave (i.e. to a multicast IP address): this is called multicast,
in IPv4 or IPv6.
To get the complete list of VLC’s possibilities on each plateform supported, see the VLC features page
(http://www.videolan.org/vlc/features.html).
Note: VLC doesn’t work on Mac OS 9, and will probably never do.
Mini-SAP-server
You can add a channel information service based on the SAP/SDP standard to the VideoLAN solution. The
mini-SAP-server sends announces about the multicast programs on the network in IPv4 or IPv6, and VLCs receive these
annouces and automatically add the programs announced to their playlist.
The mini-SAP-server works under Linux and Mac OS X.
Muxers and codecs
What is a codec ?
To fully understand the VideoLAN solution, you must understand the difference between a codec and a container format
