-DisOrder and Republishing Internet Streams
-==========================================
+* Introduction
-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:
+This file describes DisOrder's relationship to several different things that
+get called 'streams'.
- player /export/radio/*.oggradio shell 'xargs ogg123 -q < "$TRACK"'
- collection fs iso-8859-1 /export/radio
+* RTP Streaming
-After setting this up you'll need to re-read the config file and provoke a
-rescan:
+DisOrder is capable of transmitting RTP streams over a suitable network.
- disorder reconfigure rescan /export/radio
+** Server Setup
-/export/radio contains a file for each stream, containing the URL to use:
+To enable this make sure that all players use the speaker process, i.e. execraw
+rather than exec (or it won't work properly) and configure the network speaker
+backend:
- lyonesse$ cat /export/radio/CUR1350.oggradio
- http://cur.chu.cam.ac.uk:8000/cur.ogg
+ api network
+ broadcast 172.17.207.255 9003
+ broadcast_from 172.17.207.2 9002
-You'll probably want to prevent random play of streams:
+The destination address (broadcast) can be:
+ - a broadcast address for a local network
+ - a multicast address
- disorder set /export/radio/CUR1350.oggradio pick_at_random 0
+The source address (broadcast_from) is optional but may be convenient in some
+cases.
-You can then queue a stream like any other track. It won't automatically
-interrupt the playing track, you have to scratch it manually. Go back to
-normal play by scratching the stream.
+If the destination is a multicast address then you should set the TTL, for
+instance:
+ multicast_ttl 10
-RTP Streaming
-=============
+(The destination can also be a unicast address but that's not a tested
+configuration.)
-DisOrder is now capable to transmitting RTP streams over a suitable network.
-To enable this make sure that allplayers use the speaker process, i.e. execraw
-rather than exec (or it won't work properly) and configure the network speaker
-backend:
+scripts/setup now knows how to do basic setup for network play.
- speaker_backend network
- broadcast 172.17.207.255 9003
- broadcast_from 172.17.207.2 9002
+** Playing The Stream
-broadcast_from is optional but may be convenient for some cases.
+To play, use the disorder-playrtp client. If the destination address was a
+unicast or broadcast address then:
-To play, use the disorder-playrtp client.
+ disorder-playrtp 9003
- 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 the ~/.disorder directory.
+
+** Limitations
Currently only 16-bit 44100Hz stereo is supported, which requires about
-1.4Mbit/s. Possibly other lower-quality but lower-bandwidth encodings will be
-supported in future.
+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.
-If you have a too-recent version of sox you may need to set the sox_generation
-option.
+Possibly other lower-quality but lower-bandwidth encodings will be supported in
+future.
+
+If you have a very recent version of sox you may need to set the sox_generation
+option. See disorder_config(5).
-Icecast Streaming
-=================
+* 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,

This doesn't seem to get on very well with pausing but you're unlikely to want
If you have a too-recent version of sox you may need to set the sox_generation
option.
+Mark Wooding contributed the original support for this but it's been modified
+enough that he probably shouldn't be blamed for any bugs in the current code.
