I'd like simply to stream a video/audio from an Axis camera managed by a Wowza Server Engine and display the video/audio on Firefox browser. The streaming flow from the camera (H264, AAC 16000) is transcoded with the help of ffmpeg to H264, AAC(48000). This produces 2 audio channels (as visibile in SDP) which allows to be displayed by the browsers after Wowza transcoding to VP8, OPUS and mpeg-ts. In Chrome it works fine. In Firefox (tested 49 and 50beta) some errors occur.

The console gives: ICE failed, see about:webrtc for more details

When displaying about:webrtc I have:

From SDP Local

a=candidate:0 1 UDP 2122252543 192.42.172.126 58085 typ host

From SDP distant

a=candidate:0 1 TCP 50 192.42.172.189 6558 typ host generation 0

Logs about:webrtc :

If I change in VHost.xml the value of webrtcIceCandidateIpAddresses to work on UDP (it means from wowza IP 192.42.172.189,tcp,6558 to 192.42.172.189,udp):

<Property> <Name>webrtcIceCandidateIpAddresses</Name> <Value>192.42.172.189,udp</Value> <Type>String</Type> </Property>

I will have the same error in console. In about:webrtc I will have:

I tried to find a solution by searching on the net a possible cause, without results. Could someone help, please ?

The WebRTC Firefox connection issues has been resolved with Wowza Streaming Engine 4.5.0.04 updater. Please open a support ticket to request this updater if you do not already have it.

    I am using the version 4.6.0 and I am having the same problem, it works on Chrome and on my Android cellphone but it isn't working on my Firefox Browser (v 51) – Maximiliano De Lorenzo Feb 23 '17 at 12:03

Latest stable Firefox (OSX) and 4.7.x of Wowza Streaming Engine and I also do see this issue ;-( Tried setting up an empty Wowza Application to make sure it's not settings related, but that did not help...
