webrtcdsp / webrtcechoprobe on macos

[jordi domenech flores]

Hi!
I've been trying for a while to run a simple hello world with webrtcdsp /
webrtcechoprobe without success. tbh I'm far from an expert, just trying to
study and understand gst, sorry if I'm being too naive...

I'm on macos M1 using latest stable (1.22) and the pipeline is:

gst-launch-1.0 -v \
osxaudiosrc buffer-time=20000 ! \
queue ! \
webrtcdsp ! \
webrtcechoprobe ! \
osxaudiosink buffer-time=20000

Also tried the bare minimal:

gst-launch-1.0 -v \
osxaudiosrc ! \
webrtcdsp ! \
webrtcechoprobe ! \
osxaudiosink

Actually, it's just a "port" of docs:
https://gstreamer.freedesktop.org/documentation/webrtcdsp/webrtcdsp.html?gi-language=c#example-launch-line

No matter what I do, I always get infinte echo until distortion. What's
wrong?!
Hope somebody can explain what's the problem... In any case, thanks for
your time!
