[asterisk-users] buffer-issue when piping live-streams into musiconhold

[Michael Kamleitner]

Hi Folks,

I'm currently trying to configure musiconhold (on a asterisk-1.4.17) for
replaying a live mp3-stream (Icecast2). after reading the related material
on voip-info and several other pages, I've successfully tried out mpg132,
madplay and mplayer to pipe a stream into moh.

however, there is one major problem involving some kind of buffer-issue. let
me try to explain this problem using a timeline:

10:00 I'm calling the pbx, musiconhold starts correctly to play the
live-stream (almost live, with very small delay) - that's OK.
10:01 I hangup.

-- than I pause for 20 min --

10:20 I'm calling a second time. However moh now doesn't stream live, but
starts to continue playing the stream from 10:01. This goes on for about
30secs, then the replay stops for a second and continues at the correct
position (once again, rather "live"). along I get this message at the
console:

[Jan 17 20:37:15] NOTICE[6220]: res_musiconhold.c:544 monmp3thread: Request
to schedule in the past?!?!
[Jan 17 20:37:15] NOTICE[6220]: res_musiconhold.c:544 monmp3thread: Request
to schedule in the past?!?!

I've installed the ztdummy-module as I've read that the message "Request to
schedule in the past?!?!" might have something to do with that, however this
didn't help.

It looks like there's some kind of buffering going on...

Thanks a lot for any suggestions, at this point I'm rather clueless ;)

regards,
michael
