WARNING: erroneous pipeline: no element "pulsesrc"

[crypdick]

When I try to run gst-launch-1.0 -m pulsesrc ! audioconvert ! audiorate ! audioresample ! deepspeech silence-threshold=0.3 silence-length=20 ! fakesink I get the following error:

WARNING: erroneous pipeline: no element "pulsesrc"

I made sure pulseaudio is running:

By the way, when I run gst-inspect-1.0 deepspeech I get the no plugin error, but it works fine when I run it as sudo. Ditto with pulsesrc. I suspect things are getting installed with the wrong permissions?

Running as sudo comes with its own issues:

sudo gst-launch-1.0 -m pulsesrc ! audioconvert ! audiorate ! audioresample ! deepspeech silence-threshold=0.3 silence-length=20 ! fakesink

Hi crypdick,

If pulsesrc is only found as root as well then it would appear to be something more general going wrong with gstreamer on your system/user, as pulsesrc isn't part of gst-deepspeech, it's a well established gstreamer plugin (from the gstreamer1.0-plugins-good package).

Could you try deleting your user's gstreamer plugin registry cache (iirc: ~/.cache/gstreamer-1.0/registry*), then running GST_DEBUG=5 GST_DEBUG_NO_COLOR=1 gst-inspect-1.0 > log.txt 2>&1 and upload log.txt. I'll take a look and see if there's anything obvious I can see going wrong there.

Thanks! Mike

Ah, I think I've spotted the issue; it looks like you're using anaconda and it's setup environment variables for your user to just search for gstreamer plugins inside the anaconda environment:

0:00:00.003892203 12021 0x5559c5e56c00 DEBUG GST_REGISTRY gstregistry.c:1663:scan_and_update_registry: scanning main plugins /home/richardd/bin/anaconda3/lib/gstreamer-1.0

Presumably you don't have gstreamer-plugins-good installed within the anaconda environment which is why it's not finding pulsesrc, and gst-deepspeech will install to /usr/local/ by default (or /usr/ for the PPA packages) so it's not seeing the deepspeech plugin either.

My advice would be to simply disable the anaconda environment prior to running gst-deepspeech based things; but alternatively you could attempt to compile everything against the anaconda version of the gstreamer libraries and install within the anaconda environment instead.

Sorry for the delay. My workstation bit the dust and I finally have a new box set up.

I installed gstreamer in anaconda:

conda install -c anaconda gstreamer
conda install -c anaconda gst-plugins-base
conda install -c retrev gst-plugins-good 

That didn't help the no element "pulsesrc" error. I finally got things working by running

/usr/bin/gst-launch-1.0 -m pulsesrc ! audioconvert ! audiorate ! audioresample ! deepspeech silence-threshold=0.3 silence-length=20 ! fakesink
