5.2 URL Variable Substitution

URLs may contain variables which are processed and substituted by their values.

Variables have syntax $NAME$, where name consists of printable upper case

characters other than '$'. Following variable names are defined:

Name Description Example

MAC Device MAC address (12 digits in hexadecimal

notation with no separators, A..F digits in capital

letters)

0008E1002B0E

IP Device IP address (four numbers, dot separated,

without leading zeroes)

192.168.2.202

NAME DHCP Host name (ASCII string configured in network

settings)

XSTREAM1

NUM channel number (three digits) 003

When the device is fetching a stream then the above variables will be substituted.

This allows for specific tasks like identification, zoning and logging of the device.

The variable $NAME$ for an example could be used to group several devices to a

zone which will be supplied with different streams by the server analyzing the name

of the fetching device.

Example:

• URL1: http://myserver.com:4567/device.cgi?

zone=$NAME$&id=$MAC$&logip=$IP$

• URL1: http://myserver.com:4567/device.cgi?

channel=$NUM$&id=$MAC$&logip=$IP$

The variable $NUM$ can also be used to select numbered playlists stored on a USB

memory stick using the IR remote control.

5.3 Triggered Message Playback

Streaming Client supports playback of files from a local storage triggered remotely

via Shoutcast or by a command. This can be useful e.g. for playing local adverts,

pre-recorded announcements, etc. To use this feature enter a playlist name in the

Priority section of Advanced Settings.

The following special names in StreamTitle section of Shoutcast metadata (song

name) are recognised:

• BARIX song next : plays next song from the priority playlist

• BARIX song N : where N is an integer number, plays N-th file from the

playlist. N counts from 0.

Further, the playback can be triggered with the S=N command:

• S=-1 : plays the next song from the priority playlist

• S=N : where N is an integer number, plays N-th file from the playlist. N

counts from 0.

When such a trigger is received, the current playback (URL1-3) stops, the requested

file from the local playlist is played and when the file ends then the normal playback

(URL1-3) starts again. The triggered playback is considered as priority and therefore

also “Priority message” appears on device's display.

If Shuffle is on the “next song” command picks up a random song. The play N-th file

command is not affected by shuffle.
