Hi all,
I'm using an instance of Liquidsoap for a studio-to-transmitter link
running for 72 hours.
I get the audio with a USB soundcard connected to a PC with Stretch
(encoder), liquidsoap writes on the HDD, streams to a RaspberryPi on LAN
(decoder), and to a distant server (webradio).
Every (+/-) 106 minutes i get a message that the buffers are emptied. I
read on this mailing list that is due to my cheap soundcard not sampling
at exactly 44.1kHz.
So when it occurs, i have a 1sec blank, that is not a big problem to me..
But, I have a second problem, and I don't know if it's related : I got a
"We must catchup 10.44 seconds!"
And on the audio on the decoder I got a 11sec blank.. (11:22:33 - 11:22:43)
Do you think these problems are related, and do you have an idea how can
I avoid that catchup problem please ?
Thanks !
Yann
