i have the publisher/controller/loop until live all setup/automated with ffmpeg
providing 4 live streams which rotate
this allows me to have a ‘main stream’ in which the wowza server rotates
content on a time based schedule. the cut between streams is very subtle.
the 2 modules im using are stream publisher and loop until live
in wowza/conf/live/Application.xml

to sum it all up im generating 2 spectrograms and 2 waveforms using the audio
from a shoutcast server. each one plays for 24 hours before switching to the
next one in the list. if a stream is published with the name djstream, it will
immediately switch to that content… once djstream is finished it goes back to
the schedule again, rotating once every 24 hours to the next stream… the single
i believe the app type has to be ‘live’ for most of this stuff to work, and i
dont think you can switch to a stream published to a different app.
results -> http://dsfm.tv
ok enough wowza on the ffmpeg list.. let me know if you have any q’s, etc
cheers!
