Edge: Legacy mandatory/optional constraints not supported.

[zdila]

Browsers and versions affected AdapterJS 0.14.0

Edge 38 on Windows 10

Description

Exteption with message "Legacy mandatory/optional constraints not supported." when calling createOffer

[fippo]

Those constraints are chrome-specific. What constraints are you trying to pass?

[zdila]

Thank you. You were right. After fixing that problem we are getting SCRIPT5022: InvalidAccessError at line marked with XXX:

  } else if (navigator.mediaDevices && navigator.userAgent.match(/Edge\/(\d+).(\d+)$/)) {
    // Attach a media stream to an element.
    attachMediaStream = function(element, stream) {
      element.srcObject = stream; // XXX
      return element;
    };

So far we are trying to do audio-only call.

[fippo]

that looks like a very, very old version of adapter...

[zdila]

It is 0.14.0, latest in the npm repository.

[fippo]

this npm package for this adapter is https://www.npmjs.com/package/webrtc-adapter

[zdila]

Thanks. But does that one support MSIE and Safari? Because this one "provides support for WebRTC in Internet Explorer and Safari on Mac and Windows through the available Temasys Browser Plugins.".

[zdila]

Oh sorry. I reported this issue to wrong project then :-O

[AndriiDronDiachuk]

zdila, how exactly did you fix "Legacy mandatory/optional constraints not supported"?

[fippo]

@AndriiDronDiachuk replace any createOffer({mandatory: {OfferToReceiveAudio: true}}) or similar with createOffer({offerToReceiveAudio: true}). Firefox should complain a lot about this already.
