How to send both audio and video with a livekitwebrtcsink element

ti-guru · April 12, 2025, 11:59am

Hi,

I’m trying to use the livekitwebrtcsink in a python app to send both audio (from a mic) and video (multiple sources combined into one stream with a compositor) to a LiveKit room using gsreamer 1.24.2 and rswebrtc 0.14.0-alpha.1-7e2a4cf6 release date 2025-02-03.

I have no problems publishing video only. Any help on how to get audio+video publishing working would be much appreciated!

The pipelines can be simplified as following:

# Terminal 1 - Audio source
gst-launch-1.0 autoaudiosrc \
! queue ! audioconvert ! audioresample \
! unixfdsink socket-path=/tmp/audio-device

# Terminal 2 - Video source
gst-launch-1.0 v4l2src device=/dev/video0 \
! jpegdec ! video/x-raw,width=1280,height=720,framerate=30/1 \
! timeoverlay ! videoconvert ! queue \
! unixfdsink socket-path=/tmp/v4l2-device

# Terminal 3 - Publish stream
gst-launch-1.0 unixfdsrc socket-path=/tmp/v4l2-device \
! videoconvert ! queue \
! livekitwebrtcsink name=livekit-sink \
  signaller::ws-url=ws://127.0.0.1:7880 \
  signaller::api-key=devkey \
  signaller::secret-key=secret \
  signaller::room-name=testroom \
  signaller::identity=gst-producer \
  signaller::participant-name=gst-producer \
  video-caps='video/x-vp8' 
  unixfdsrc socket-path=/tmp/audio-device ! queue \
! livekit-sink.audio_0

# Terminal 4 - Watch the stream
gst-launch-1.0 livekitwebrtcsrc name=livekit-src \
  signaller::ws-url=ws://127.0.0.1:7880 \
  signaller::api-key=devkey \
  signaller::secret-key=secret \
  signaller::room-name=testroom \
  signaller::identity=gst-consumer \
  signaller::participant-name=gst-consumer \
! queue ! videoconvert ! autovideosink \
livekit-src.audio_0 ! queue ! audioconvert ! autoaudiosink

This fails with the following error in terminal 3:
