I've been trying to find a good way to a stream of audio from jack into opusenc (the
official opus encoder tool) and then pass it to something like oggfwd to send to Icecast.
However, a few different things I've tried in python haven't worked out, and
I'm trying to not have to rely on an "audio file player" (like sox or
pyaudio) to sit in the middle. Now I'm wondering if there's a way I can get the
raw pcm data from jack. Is this possible? Is there an existing tool?

I use ffmpeg to stream Opus to icecast:
/usr/bin/ffmpeg -f jack -i opus -vn -acodec libopus -ar 48000 -ac 2 -ab
64k -content_type audio/ogg -f ogg
icecast://source:password@127.0.0.1:8000/opus
It's not the new flags, but it'd be straightforward to update.

You should be able to get raw audio data by means of any JACK API i.e.,
in Python this works very well with jack-client

Thanks, I'll give this a try. Hopefully it will allow me to select the specific
capture port I want to stream from.

Thanks, I'll look into how other libraries use the jack API to read the data and use
this lib to try and attempt the same.
