Firefox problems

[yarekc]

The sample works fine on chrome but on firefox, there are some problems

1. easy fix: Firefox cannot use planB
2. firefox has problems to reconnect.
   Scenario: (chrome or Firefox) streams
   Firefox watches: OK
   Chrome watches: OK

(chrome or Firefox) disconnects and reconnects and stream again
Chrome watches OK
Firefox watches KO !

Thanks for your report.
I am trying to reproduced the problem.
Would you tell me some more information?

1. Which server are you using?
   a) mediasoup_sample_multi.js
   b) mediasoup_sample_multi_ssl.js
   c) mediasoup_sample_multi_socketio.js
   d) mediasoup_sample_multi_socketio_ssl.js

2. Which client html are you using?
   a) bidirectional video chat (index.html or variations)
   b) 1 way realtime streaming (talk.html, watch.html or extended version by you)

I do use c) (but slightly modified)
You can test it directly on:
https://webtv.fr/mediasoup

This works cool on chrome but will give you errors on firefox

2. I used a modified version but tried a) and b) and still problems
   here is the version I do use:
   https://webtv.fr/mediasoup/node/server.js

I can also provide you SSH root access if it is easier.

I got some answers from the mediaSoup creator and here it is:

Please check
https://github.com/versatica/mediasoup-demo/blob/master/server/lib/Room.js#L508
(note the peerconnection.reset() usage to avoid PeerConnection in
wrong state when no answer is received for a sent re-offer).

Hi,
did you find any clue for this firefox issue ?

Thanks for your information.

I find a strange behavior with Firefox on my sample code.
I am not sure if it is same as your situation.

I am afraid that it tokes time to figure out what is wrong.
