Re: [Savonet-users] output.udp and input.udp

[Romaric P. <ro...@sa...>]

Hi David,

This is the error I get when I launch the LS process with 'channels=1' into
the 'input.external'

"Starting liquidsoap channels: roma.liq Invalid value at line 2, char 88:
  Incompatible number of channels, please use a conversion operator.."


The command is: my_src = audio_to_stereo(input.external(id="voice",
restart=false, buffer=0.0, channels=1, samplerate=44100,"sox /tmp/audio.wav
-c 1 -r 44100 -t raw -"))


Regards

Romaric

The string is a MIME type. The MIME types are used in the same way as with
HTTP inputs. In your case, audio/wav should do.

The reason why it doesn't expect a format is that formats contain
information only relevant for encoding, not decoding. (When you use an
MP3 decoder, you don't need to tell it that MP3 is going to be mono
96kpbs.)

'channels=1'??

Looking at the type, it should accept this option, at least at the language
level. Are you getting a runtime error? are you sure that your application
produces mono PCM?

Hope this helps,
