Is p2p screen sharing still supported?

[jusahah]

Hey,

first of all, great work with developing these extensions!

Lately however, desktopCapture-p2p has stopped working when used over public internet. I guess this is an issue with STUN/TURN, as the extension works perfectly when used over localhost or local network.

Issue

When using desktopCapture-p2p over public network, the connection is made (i.e extension shows that a viewer is present), but no video stream is shown in the viewer-side. On the viewer page, console is logged with messages like this:

adding candidate candidate:3511702143 1 udp 2113937151 {ip} 49421 typ host generation 0 ufrag uwwl network-cost 999

This happens with latest versions of Chrome and Firefox.

Wondering if you have any tips or guide how to solve this?

Thanks.

Have you got the solution?

No, I haven't. If anyone knows how to solve this, lets share. From what I've gathered from Google searches, this seems to be common problem for many people. :)

I installed coturn today to replace the STUN/TURN from google with my own STUN/TURN.

This article may be helpful to install coturn. After coturn is installed, I have problem to check STUN/TURN in Chrome using this tool, however, it's OK for Firefox. I guess it's not the server's fault but the Chrome's (also found this issue). After you test the connection successfully in Firefox, continue to replace the STUN/TURN urls in desktopCapture-p2p code. Don't forget to check the urls in these three files:

1. AntMediaWrapper.js
2. IceServersHandler.js
3. RTCMultiConnection.min.js

The extension only works when I use the IP of the STUN/TURN server, cannot use domain. If anyone can confirm that or know the reason, please let me know.

I also updated libs, RTCMultiConnection.min.js and socket.io.js to the latest version, but I think it's optional to solve the issue.
