WebRTC和Wowza在Firefox上的流式傳輸

Question

我想簡單地從由Wowza服務器引擎管理的Axis攝像頭中流式傳輸視頻/音頻，並在Firefox瀏覽器上顯示視頻/音頻。 來自相機（H264，AAC 16000）的流動流在ffmpeg的幫助下轉碼爲H264，AAC（48000）。這產生了2個音頻通道（作爲SDP中的visibile），允許瀏覽器在Wowza轉碼爲VP8，OPUS和mpeg-ts後顯示。 在Chrome中，它工作正常。 在Firefox（測試49和50beta）中會發生一些錯誤。

的控制檯提供： ICE failed, see about:webrtc for more details

當顯示一下：我的WebRTC有：

從SDP本地

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

從SDP遙遠

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

個

記錄有關：的WebRTC：

如果我在VHost.xml webrtcIceCandidateIpAddresses的值更改爲UDP上工作（從wowza IP 192.42.172.189，TCP，6558到192.42.172.189，UDP指）：

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

我將在控制檯同樣的錯誤。 在約：我的WebRTC將有：

SDP本地

a=candidate:0 1 UDP 2122252543 192.42.172.126 50662 typ host

SDP遙遠

a=candidate:0 1 UDP 50 192.42.172.189 6974 typ host generation 0

我試圖通過在網絡上搜索可能的原因找到解決方案，但沒有結果。 有人可以幫忙嗎？

Answer 1

的的WebRTC的Firefox連接問題已得到解決Wowza流引擎4.5.0.04更新。如果您尚未擁有支持請求，請打開支持請求以請求此更新程序。

最新穩定火狐（OSX）和Wowza流引擎的4.7.x和我也確實看到了這個問題;-(試圖建立一個空的Wowza應用程序，以確保它不相關的設置，但這並沒有幫助...
