Hi @coderpradp

1. make sure that you call switchMediaTracks after getUserMedia with elementId param https://developers.connectycube.com/js/videocalling?id=access-local-media-stream
2. make sure that when you call method switchMediaTracks, element on which you have attached local stream exists in DOM

Hi @banshiAnton

1. I am calling switchMediaTracks after getUserMedia, however I'm attaching the stream with session.attachMediaStream('myVideoElementId', stream);
2. Yes, the local stream exists on DOM.

[banshiAnton]

try to call getUserMedia() with params { (your media webrtc sessions), elementId: 'myVideoElementId' }

[coderpradp]

try to call getUserMedia() with params { (your media webrtc sessions), elementId: 'myVideoElementId' }

That won't work for me since it's a single page application, it will result in HTMLVideoElement undefined. That is why I am attaching stream with session.attachMediaStream method.

[banshiAnton]

before call session.switchMediaTracks
add this code

session.mediaParams.elementId = 'myVideoElementId'

[coderpradp]

before call session.switchMediaTracks
add this code

session.mediaParams.elementId = 'myVideoElementId'

This fixed the issue. Thank you.
