Chapter 12. Streaming over IPv6

Streaming with VLC

With the Streaming Wizard (GUI)

The streaming wizard accepts IPv6 addresses between braces, for example:

[2002:8ac3:802d:1242:211:11ff:fe25:e6b4]. If you specify a link-local address, you will most likely need to

specify the networking interface to use. On Unix, that can be done this way: [fe80::211:11ff:fe25:e6b4%eth0] to

attach to eth0. Similarly, on Windows, you may specify [fe80::211:11ff:fe25:e6b4%1] where 1 is the number of the

network interface as deﬁned by the operating system.

If you’re streaming over HTTP, note that IPv6 is automatically used by default (so that both IPv6 and IPv4 clients will be

allowed).

If you want to specify DNS hostname, keep in mind that the VLC defaults to IPv4 resolution. You must either specify

hostnames that only resolves to IPv6 addresses, or enable the "Force IPv6" advanced option in Preferences / General

Settings / Input.

From the command-line

The --ipv6 command line option force the use of IPv6 by default (ie. IPv6 is always attempted before IPv4).

% vlc -vvv video1.xyz --sout ’#rtp{mux=ts,dst=ff08::1}’ --ttl 12

where:

• video1.xyz is the ﬁle you want to stream (you can also put dvdsimple:///dev/dvd to stream a DVD or any other input

conﬁguration) ,

• ff08::1 is either :

• the IPv6 address of the machine you want to unicast to;

• or the multicast IPv6 address.

• 12 is the value of the TTL (Time To Live) of your IP packets (which means that the stream will be able to cross 11

routers).

Note: You may have to specify the output network interface:

% vlc -vvv video1.xyz --sout ’#rtp{mux=ts,dst=ff02::1%eth0}’ --ttl 12

where eth0 is the name of the network interface (under Linux the network interfaces are named ethX , under Mac OS X

it’s enX and under Windows it’s X , where X is the appropriate number).

Receiving an IPv6 stream

With the graphical user interface

Select File / Open Network Stream. To receive an UDP/RTP unicast stream sent to your system, you should select the

Force IPv6 option (and possibly adjust the destination UDP port). To receive an UDP multicast stream, select the
