Local setup: WebRTC + firefox - ICE failed, add a STUN server and see about:webrtc for more details

I have locally set up Wowza Streaming Engine with WebRTC as outlined in this doc.

I am using

  • Wowza Streaming Engine 4 Subscription Edition 4.7.0 build20186
  • A self signed cert

I am ingesting a h264 stream from an IP camera and transcoding it to VP8. I have hosted the HTML examples on Wowza Streaming Engine as outlined in the how-to doc. When using chrome, if I go to

https://127.0.0.1:9443/webrtc/play/index.html

And enter the following

SDP URL: wss://127.0.0.1:443/webrtc-session.json
Application Name: webrtcStream 
Name: mystream.stream_vp8

The player connects and begins to stream. This works great.

However, the exact same set up with the same input in Firefox gives the error:

ICE failed, add a STUN server and see about:webrtc for more details

The contents of about:webrtc are foreign to me, so I’m not sure how to effectively debug this. Here is a screenshot of the attempt

Many similar-sounding issues I have found in previous answers mentioned the webrtcIceCandidateIpAddresses and webrtcUDPBindAddress properties that are added to conf/Application.xml - I’ve attempted some trial and error here to no avail. These are the values I’m currently sitting with in my Applcation.xml

<Property>
    <Name>webrtcIceCandidateIpAddresses</Name>
    <Value>127.0.0.1,udp</Value>
    <Type>String</Type>
</Property>
<Property>
    <Name>webrtcUDPBindAddress</Name>
    <Value>0.0.0.0</Value>
    <Type>String</Type>
</Property>

Any push in the right direction would be greatly appreciated.

Thank you.

Hey,

Was anyone able to figure this out?

Thanks in advance!

A bit embarrassed to say but I had placed my configs shown above in the wrong Application.xml - Once I spotted that it worked perfectly. Hopefully another careful look over the set up steps will reveal something you’ve slipped on.

Have you had any success solving this?

I had thought I had resolved this, but it was only working within a dev environment. Once pushed to an external server, I’m seeing it again. Wondering if you have any insight.

anyone able to find solution for this?

2 years later…anyone find a solution yet?

I was able to find something that worked, per WebRTC demo page and Firefox

It only worked for me if UDP is the only ICE candidate. I had to remove TCP completely. Even if UDP is the priority, it didn’t work.
