Not able to play the audio streamed with gstreamer (OPUS codec) on VLC player

I want to stream live audio with gstreamer using ‘opus’ codec. At the transmitter end I am using the following script:

Transmitter:
" gst-launch-1.0 autoaudiosrc ! audioconvert ! audioresample ! opusenc bitrate=48000 max-payload-size=101 packet-loss-percentage=0 frame-size=20 bandwidth=fullband audio-type=generic hard-resync=false inband-fec=true complexity=10 bitrate-type=constrained-vbr ! rtpopuspay ! udpsink host=224.0.0.161 port=5001 "

Receiver: At receiver I am trying to receive the stream with VLC player using the following script:
“vlc stream.sdp”

SDP file content: stream.sdp

m=audio 5001 RTP/AVP 101
c=IN IP4 224.0.0.161
a=rtpmap:101 opus/48000/1
a=fmtp:101 maxplaybackrate=16000;
sprop-maxcapturerate=16000;
maxaveragebitrate=20000;
stereo=1;
useinbandfec=1;
usedtx=0

But when I execute the VLC script with SDP file, nothing happens. The player remains paused.
I verified the transmitter script with ‘gstreamer’ receiver and it works fine.

I am not getting if there is something wrong in SDP file or some configuration issue is there.

I hope I’ll find some help here.
thanks.

Hi @maneesha.ebizon and sorry for the late reply.

  • Are you using ACE early access?
  • Can you share the version of Audio2Face you’re using?
  • Can you tell us the steps you’re taking so we can try and replicate this issue?
