webrtcbin: end of remote candidates

[Bizarre Days]

When Firefox browser wants to send candidates to the webrtcbin peer, it calls a custom js method passing an "event" argument to it. The custom method must send this information to the peer. The event has a single field "event.candidate" with a value as:

event.candidate = { "sdpMLineIndex":0,"

  "candidate":"candidate:8 2 TCP 847249918 88.6.179.119 9 typ srflx raddr 192.168.1.12 rport 9 tcptype active"}

At the end, to inform there are no more candidates, Firefox does another call to the same method with event.candidate=undefined

In the other side, webrtcbin (Java API) offers the method "WebRTCBin.addIceCandiate( int sdpM. String candidate ) to inform the plugin about the remote candidates. In the normal case is easy map firefox event.candidate information to these arguments. However, no idea of to handle the end one.

A call WebRTCBin.addIceCandidate(0, null) produces an assertion failed in libnice (when its trace is active).

How to handle in WebRTCBin (Java API) the case of final remote candidate ?

Thanks,

This is currently not supported but there's a MR from yesterday adding
support for this by sending a NULL/"" candidate:
