User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:92.0) Gecko/20100101 Firefox/92.0

Steps to reproduce:

On a private chat on LinkedIn I created a LinkedIn's video meeting.

The feature / button "Create video meeting" appears when I mentioned a date and time in the chat.

Actual results:

In the chat the preview of the featured link to LinkedIn's video meeting gave the message "LinkedIn video meetings aren’t available for Firefox. Please try a different browser."

Expected results:

The the preview of the featured link to LinkedIn's video meeting should mention teh user name, time and date and link to the call.

        const n = getBrowserInfo()

This is just user agent sniffing.

Let's try to fake the UA to be chrome.
The meeting starts when I fake the UA. There are errors in the console, but it's mostly working.

The main error is related to

Uncaught (in promise) TypeError: RTCPeerConnection.getStats: Argument 1 does not implement interface MediaStreamTrack.

I see a couple of issues on bugzilla related to getStats and MediaStreamTrack

Maybe Paul will know if it's a known issue.

By spec there's RTCPeerConnection.getStats(optional MediaStreamTrack? selector = null), RTCRtpSender.getStats() and RTCRtpReceiver.getStats(). All of which we implement.

Chromium has RTCRtpSender.getStats(), RTCRtpReceiver.getStats() and a non-standard legacy version RTCPeerConnection.getStats(RTCStatsCallback successCallback, optional MediaStreamTrack? selector).

It seems likely that LinkedIn is using the chromium-specific legacy version and are passing a callback. Can we verify this and reach out?

When I spoof as Safari (https://github.com/jrmuizel/safari-mask) I get the same Could not stop the video stream message

promise callback*value https://static.licdn.com/aero-v1/sc/h/3w7ejblek7bhfvw0ujinnbqbk:17457

Not seeing any failing gUM of enumerateDevices calls nearby. Looks like the app decided to stop video here:

        var e = this,

Hey Jeff, what's the str to find this? We were looking for the video conferencing option but could not locate it.

Flags: needinfo?(jmuizelaar)

In the messaging pane there's a camera icon

Flags: needinfo?(jmuizelaar)

Hmm, when I try this it presents a dialog offering to create the meeting in teams or zoom.

Ok, got a little farther here.

STR:

(You'll need two linkdin contacts that are connected)

  1. In Firefox spoof Chrome's UA
  2. Open the linkdin contact you'll use for testing in a chat window and select the video meeting icon

You should get the in-chat interface that allows scheduling a meeting. Choose a time just before current time and submit. Also select the Linkdin meeting service if presented with multiple options.

  1. After requesting the meeting, a small embedded panel should display in the chat with a meeting link
  2. Click on the meeting link

A new tab should open, which should load a 'waiting room'. You'll need to approve camera and mic access at this point.

  1. Attempt to 'Join'

Results:
After a bit, the meeting tab will simply close.

Unfortunately capturing a profile while this happens fails to capture anything from the 'crashed tab'. Also there are no crashed tab reports so it looks like the web content closed the tab and the profiler didn't collect anything for it.

Note once you have a meeting link in a chat, you can continue testing by rejoining the same meeting.

The stop video error is coming from LinkedIn trying to shut down the call due to an error. If using Chrome UA the below will fail.

                    this.sessionDescription = k.SessionDescriptionFactory.build({
                        sdpTransform: new this.webrtcAdapter.SdpTransform(this.context),
                        mediaManager: this.mediaManager,
                        logger: this.logger,
                        configProvider: this.configProvider,
                        configuration: this.getStreamTransformConfiguration()
                      }),

If using Safari UA you will get further but we need to look at the SDPs more as we are not negotiating the webrtc-datachannel maybe due to spec issue or no sctp attribute from LinkedIn.

Yeah, they're just breaking spec. There needs to be an a=sctp-port attribute in there.

https://datatracker.ietf.org/doc/html/rfc8829#section-5.3.1-25

Within the data "m=" section, an "a=mid" line MUST be generated and included as described above, along with an "a=sctp-port" line referencing the SCTP port number, as defined in [RFC8841], Section 5.1; and, if appropriate, an "a=max-message-size" line, as defined in [RFC8841], Section 6.1.

We could let this slide and assume 5000, I suppose, but that's such an easy modification on their end. Just hard-code it, and move on.

No longer blocks: webrtc-triage

So what's needed here is a minor tweak to their handling, and to remove the firefox not supported block.

Presumably Chrome lets this slide. Can we add a wpt test or otherwise try to make them stricter?

Jim - Can we outreach to LinkedIn about this? Sounds like a trivial fix for them to make.,

I don't have contacts at linked in.

We are having a hard time locating the video meeting button currently, both in Firefox with an intervention and in stock Chrome. Seems as though the feature was pulled, at least temporarily.

Looks like LinkedIn no longer offer their own video calling feature. Please reopen if you find otherwise.
