我只想从由 Wowza 服务器引擎管理的 Axis 摄像机流式传输视频/音频，并在 Firefox 浏览器上显示视频/音频。来自相机的流（H264，AAC 16000）在 ffmpeg 的帮助下被转码为 H264，AAC（48000）。这会产生 2 个音频通道（在 SDP 中可见），允许在 Wowza 转码为 VP8、OPUS 和 mpeg-ts 后由浏览器显示。在 Chrome 中它工作正常。在 Firefox（测试 49 和 50beta）中会出现一些错误。
控制台给出：
ICE failed, see about:webrtc for more details
当显示 about:webrtc 我有：

如果我在 VHost.xml 中更改 webrtcIceCandidateIpAddresses 的值以在 UDP 上工作（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>
我将在控制台中遇到相同的错误。在 about:webrtc 我将拥有：
