应用错误收集

我想简单地从Wowza Server Engine管理的Axis摄像头流式传输视频/音频，并在Firefox浏览器上显示视频/音频。来自摄像机的流媒体流（H264，AAC 16000）在ffmpeg的帮助下转码为H264，AAC（48000）。这产生了2个音频通道（在SDP中作为visibile），允许在Wowza转码为VP8，OPUS和mpeg-ts后由浏览器显示。在Chrome中，它运行正常。在Firefox（测试49和50beta）中发生了一些错误。

控制台给出： ICE failed, see about:webrtc for more details

当显示：webrtc我有：

如果我在VHost.xml中更改webrtcIceCandidateIpAddresses的值以使用UDP（这意味着从wowza IP 192.42.172.189，tcp，6558到192.42.172.189，udp）：

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

我在控制台中会遇到同样的错误。在about：webrtc我将：

我尝试通过在网上搜索可能的原因找到解决方案，但没有结果。请问有人帮忙吗？
