Hi Sam-
Yes, it is definitely a job for fallback, but I am having trouble getting
the effect I want. See code below.
What I want is something like the uncommented fallback line in this code
but for neither input to take priority - that is, I want to put on the
output the first input that is not silent, wait until it has silence, and
then select the next input (1 or 2) to break silence.
Hope this is more clear.
Dave
#/usr/bin/liquidsoap
# Feed 1
url1 = "http://somehost.com:8000/mount1";
input1 = mksafe(input.http(id="mount1",url1))
input1 = skip_blank(input1)
# Feed 2
url2 = "http://somehost.com:8000/mount2";
input2 = mksafe(input.http(id="mount2",url2))
# Two tests:
#
# this one will only stream the first one to not have silence but will
never fallback to the other
#s = fallback(track_sensitive=false, [ input1, input2 ])
# this one will switch output between input1 and input2 but when input2 is
not silent it takes priority
# over input1 - when input2 is silent input1 is on the output
s = fallback(track_sensitive=true, [ strip_blank(input2, max_blank=3.),
input1 ])
output.icecast(%mp3(samplerate=11025, bitrate=16, stereo=false),host="
somehost.com",port=8000,password="xxxxx", mount="scan_test",
icy_metadata="true", url="http://somehost.com";, name="Feed Scan",
description="Feed Scan", fallible=true, s)
