Audio issues to the host and the particpants

OpenVidu v2 Issues developing apps
1

1.As we are getting many audio issues in the session briefly we are getting echo issues.
2.Especially while screen sharing we are getting more and more audio issues.
Sometimes we can able to hear and sometimes not.

To fix this problem using GStreamerFilter helps us or do we have any other option?

First you have to make sure that you setup correctly all video elements that need to be muted and volume.

  1. Your own video needs to be muted for you
  2. The shared screen needs to be muted for everyone if it is on a different stream (not replacing the webcam video). If it replaced the webcam stream then it needs to be muted for yourself.
  3. Reducing volume to 0.9 for the video elements that need to be heard could also help

If this is all OK then it’s possible that someone uses speakers instead of a headset. Could they use a headset instead?

Thanks mihalji,
you are helping a lot!

along with these changes,by using Gstreamer filter of audio echo and pitch will add more clairty on audio to us?

Is this the filter that you are trying to use?
https://gstreamer.freedesktop.org/documentation/webrtcdsp/webrtcdsp.html?gi-language=c

It might not be possible to use it because it also requires piping the webrtcechoprobe filter and currently only a single filter works.

this one we want to use

Hmmm… this seems to add an echo to the audio, not remove it.

So, do we have any gstreamer filters to clear that audio glitches to suggest us? or this is the only solution you suggest the following thing to us…

I can only guess that you need to write a Kurento module based on GStreamer that uses the webrtcdsp filter pipelined with the webrtcechoprobe filter… so it might not be that easy.
