Hello,
What does this error mean?
This is an error that I continue receiving on my log from months, and I
think from friday things become unmanageable.
In other words, I run the script, after some minutes, or hours, it
depends it is random, but all become simply silence. The script is
running but no activity is logged, there is the mountpoint /stream with
no song and as I say before, what you can listen is simply silence.
The last entry in the log is the error in the subject.
So now I take a simplest script, with no live, no recordings, only music
and playlist. The script runs but anyway I continue having following errors:
2015/03/30 09:45:38 [buffer_19085:3] Warning: #get called when not
#is_ready! This is normal if an operator using this source has been
unused while the source has gone unavailable. If unsure about this
warning, you are very welcome to report it and ask for clarifications.
I can't understand how it is possible since all the music is stored on
the hard disk and I'm using only playlist.
I past here my script, the simplest script I have, because I think I
should start solving problems from few elements.
Please can you review it?
Thank you!
