-DisOrder and Internet Streams
-=============================
+* Introduction
+
+This file describes DisOrder's relationship to various things that get called
+'streams'.
+
+* RTP Streaming
+
+DisOrder is capable to transmitting RTP streams over a suitable network.
+
+** Server Setup
+
+To enable this make sure that all players use the speaker process, i.e. execraw
+rather than exec (or it won't work properly) and configure the network speaker
+backend:
+
+ speaker_backend network
+ broadcast 172.17.207.255 9003
+ broadcast_from 172.17.207.2 9002
+
+The destination address (broadcast) can be:
+ - a unicast address if you only want to talk to one client
+ - a broadcast address for a local network
+ - a multicast address
+
+The source address (broadcast_from) is optional but may be convenient in som
+ecases.
+
+If the destination is a multicast address then you should set the TTL, for
+instance:
+
+ multicast_ttl 10
+
+** Playing The Stream
+
+To play, use the disorder-playrtp client. If the destination address was a
+unicast or broadcast address then:
+
+ disorder-playrtp 0.0.0.0 9003
+
+If the destination address was a multicast address then you must specify that,
+for instance:
+
+ disorder-playrtp 224.2.3.4 9003
+
+If the client machine has a DisOrder configuration file allowing disorder(1) to
+connect to the server then the parameters are unnecessary: disorder-playrtp
+will figure out the details automatically.
+
+** Disobedience
+
+Disobedience is capable of running disorder-playrtp in the background (provided
+it is installed); look for the speaker icon. If it detects that the server is
+using network play then its volume control will apply to the local volume, not
+the server's volume.
+
+If you run into trouble look for *.log files in ~/.disorder.
+
+** Limitations
+
+Currently only 16-bit 44100Hz stereo is supported, which requires about
+1.4Mbit/s. At the time of writing I've found this to work fine on 100Mbit/s
+ethernet and had reports of success with 10Mbit/s ethernet, but have not had
+any success with wireless.
+
+Possibly other lower-quality but lower-bandwidth encodings will be supported in
+future.
+
+If you have a too-recent version of sox you may need to set the sox_generation
+option. See disorder_config(5).
+
+
+* Icecast Streaming
+
+This can be achieved using the speaker_command option and Icecast (see
+http://www.icecast.org/). It will only work if you use the speaker process,
+i.e. execraw for everything.
+
+I used:
+
+ speaker_command "ices2 /etc/disorder/ices.xml"
+
+where ices.xml is:
+
+ <?xml version="1.0"?>
+ <ices>
+ <background>0</background>
+ <logpath>/var/log/ices</logpath>
+ <logfile>disorder.log</logfile>
+ <loglevel>4</loglevel>
+ <consolelog>0</consolelog>
+ <stream>
+ <metadata>

+ <param name="rate">44100</param>
+ <param name="channels">2</param>
+ <param name="metadata">1</param>
+ <param name="metadatafilename">/var/disorder/icedata</param>
+ </input>
+ <instance>
+ <hostname>lyonesse.anjou.terraraq.org.uk</hostname>
+ <port>8000</port>
+ <password>SOURCE PASSWORD HERE</password>
+ <mount>/disorder.ogg</mount>
+ <reconnectdelay>2</reconnectdelay>
+ <reconnectattempts>5</reconnectattempts>
+ <maxqueuelength>80</maxqueuelength>
+ <encode>
+ <nominal-bitrate>64000</nominal-bitrate>
+ <samplerate>44100</samplerate>
+ <channels>2</channels>
+ <flush-samples>8820</flush-samples>
+ </encode>
+ </instance>
+
+ </stream>
+ </ices>
+
+This doesn't seem to get on very well with pausing but you're unlikely to want
+to pause a stream in any case. I used IceCast 2.3.1 and Ices 2.0.1. You can
+play the stream with XMMS or whatever. The total setup seems to play rather
+behind the 'current' time, watch this space for a fix (or contribute one!)
+
+If you have a too-recent version of sox you may need to set the sox_generation
+option.
+
+
+* DisOrder and Republishing Internet Streams
DisOrder doesn't have any built-in support for playing streams but you can make
it do so. I use the following in my configuration file:
interrupt the playing track, you have to scratch it manually. Go back to
normal play by scratching the stream.
