Thanks for answer!
Here is full script:
-------------------------------------------
#!/usr/bin/env liquidsoap
set("init.daemon", true)
set("init.daemon.change_user", true)
set("init.daemon.change_user.user", "liquidsoap")
set("init.daemon.change_user.group", "liquidsoap")
set("server.telnet", true)
def stop_after_current =
raw_output = get_process_lines("./stop_after_current.py")
stop = list.hd(raw_output)
if stop == "true" then
{false}
else
{true}
end
end
live = input.harbor("live", port=8008, password="***",
metadata_charset="CP1251")
live2 = input.harbor("live2", port=8008, password="***",
metadata_charset="CP1251")
mlive = add([live, live2])
music = playlist(reload=3600, "/home/liquidsoap/files/music")
jingles = playlist(reload=86400, "/home/liquidsoap/files/jingles")
nonstop = smart_crossfade(mksafe(rotate(weights=[3, 1], [music, jingles])))
nonstop = switch(track_sensitive=false, [(stop_after_current, nonstop),
({true}, blank(id="", duration=20.0))])
stream = nrj(fallback(track_sensitive=false, [mlive, nonstop]))
out = output.icecast(host="live2.crazyradio.net", port=8000,
password="***", name="Rap Music", description="Rap-канал нашего
сумасшедшего радио =)", genre="Rap", url="http://crazyradio.net/";,
encoding="UTF-8")
out(%mp3(bitrate=128), mount="128", stream)
out(%mp3(bitrate=96), mount="96", stream)
out(%mp3(bitrate=24), mount="24", stream)
-------------------------------------------
stop_after_current.py just print on stdin "true" or "false", where "true"
means we need to stop playlist after current track.

On the contrary, nonstop always available, I can't get to play the silence.
The overall objective of this: I need to make the transition from the
nonstop to a dj more beautiful - when a song ends, without any
interruptions and circumcision connect a dj. It's possible, but then it's
difficult to guess, in what moment start broadcast, via telnet I can find
the time to the end of the track (128.remaining), but all the same, rarely
just get in the end, all the more, together with the crossfade. But if
after track will be quiet, you can later enable the translation, there will
be a slight pause, but will not circumcision track.
If I add a debug code to the function, i see, that stop_after_current calls
only once, at start.
P.S. Once again, sorry for English, I have used a translator.
