Marvin,
I'm back. And it works. If the live stream client stops, then the
fallback file starts playing, on endless loop. If the stream client
comes back up, the listener is returned to the live stream. IOW -- it
works as advertised.
Here's what I have in my icecast.xml:
<mount type="normal">
<mount-name>/stream</mount-name>
<max-listeners>3</max-listeners>
<burst-size>65536</burst-size>
<fallback-mount>/400Hz_192kbps.mp3</fallback-mount>
<fallback-override>1</fallback-override>
<fallback-when-full>1</fallback-when-full>
<!-- <username>othersource</username>
<password>hackmemore</password>
<dump-file>/tmp/dump-example1.ogg</dump-file>
<intro>/example_intro.ogg</intro>
<hidden>1</hidden>
<public>1</public>
<authentication type="htpasswd">
<option name="filename" value="myauth"/>
<option name="allow_duplicate_users" value="0"/>
</authentication>
<http-headers>
<header name="Access-Control-Allow-Origin"
value="http://webplayer.example.org" />
<header name="baz" value="quux" />
</http-headers> -->
</mount>
My static fallback file is an mp3 containing just a 400Hz sine wave at
0dBFS for the purpose of calibrating the signal path right now. It will
be replaced with appropriate music and announcements to cover for the
event of a down stream. The file has to be, as is described elsewhere in
the Icecast documentation, the same bitrate and format (stereo, in my
case) as the live mount.
Thanks for the help!
