I have some work implemented for this as an extension to my 10pre code.
The interfaces are not documented yet as I wanted to try different use
cases. If you are interested then you are welcome to try it out and
with this, each listener is allocated a group id (default 0) which the
server will use to lookup a file to play. The number of groups is
determined by the <mount> setting <jingle-groups>. At the moment the
group is only set in auth url by the Jingle-group; header, although I do
have a hardcoded switch to allocate the next id to the next new listener
You essentially set the group to file mapping via admin eg
files are in webroot. You then just trigger when the inserts are to be
run. This is where things differ slightly.
With vorbis streams, the trigger is a simple vorbis file from the source
client that lasts however long you want (can be silence as the content
won't be sent to listeners) but has a Jingle: in the headers.
With non-ogg streams things get more awkward as you don't have the same
sort of information in stream and metadata inserts are not good enough.
The mechanism currently uses the /admin/jingle interface again but you
have an option of
informs the server that this stream will be in jingle mode for 10
seconds. Any jingle files lasting longer than that will complete then
return listeners to the stream.
same sort of thing but a toggle
I suspect the latter will be better so that people can interface with
their source clients better. eg
get next file
if file is insert marker then
if insert marker finished then
