viviemxd / webrtc-screen-share Goto Github PK

Hello There,
I followed the instructions for chrome but still unable to run the app on Firefox. It says "screen capturing is either denied or not supported". How can I troubleshoot this? also my node server is accepts the connection. But I get following errors:

1. "e no defined" error.

2. The operation is insecure.
   I am waiting for the reply.

Hello,

This code is good as a start point for the conference screen sharing. I like the command line parameters method which is not depend on plugin.
Is it still maintained? I notice the code is submitted 2 years ago. Has it been tested on recent environment?
I got it merely works on 2 clients. After modify the index.html code, it gets better experience.
I.E. in line 367, modify
pc.addStream(localStream);
to
if(localStream)
pc.addStream(localStream);

But the screen can not share to more than 1 other client.
The receivers' log like:

And the server console displays:

The sender looks OK. But nothing received on the clients side. Is there any ideas?
