I verified WebRTC works with https://download.01.org/crosswalk/releases/crosswalk/android/beta/7.36.154.12/ and https://apprtc.appspot.com/ on my Nexus 5.

我验证了WebRTC可以在我的Nexus 5上使用https://download.01.org/crosswalk/releases/crosswalk/android/beta/7.36.154.12/和https://apprtc.appspot.com/。

Hope it works for you.

希望对你有效。

I had the same issues as you, but only for some clients, and I explored the same avenues that you did. The last thing (and probably the ultimate cause of my issues) was related to the NAT situation behind at least one of the clients. There will always be the possibility of a situation where one of the clients cannot get a hole punched in their NAT, and therefore a STUN server will not work. In these cases, you need a TURN server to relay the video to that client.

我遇到了和你一样的问题,但只针对一些客户,我探索了你所做的相同途径。最后一件事(可能是我的问题的最终原因)与至少一个客户背后的NAT情况有关。总有可能出现这样的情况:其中一个客户端无法在其NAT中打孔,因此STUN服务器将无法工作。在这些情况下,您需要TURN服务器将视频转发到该客户端。

What configuration do you have for your iceServers in your peerConnection? Does it contain any TURN servers that you know to work?

您在peerConnection中为iceServers配置了什么配置?它是否包含您知道可以使用的任何TURN服务器?

You can create a free account on this site http://xirsys.com/simplewebrtc/, and follow the simple instructions on getting credentials for a TURN server on their hosting, which you can then use to test if this is the issue.

您可以在此站点http://xirsys.com/simplewebrtc/上创建一个免费帐户,并按照有关在其托管上获取TURN服务器凭据的简单说明进行操作,然后您可以使用它来测试这是否是问题。

First create Peer connection and then add MediaStream to it. Only after adding mediastream to peerconnection exchange of offer,answer,candidates should be done.

首先创建Peer连接,然后将MediaStream添加到它。只有在将mediastream添加到peerconnection交换报价,答案后,才应该完成候选人。

Instead of using "decodeURIComponent" why don't you try "JSON.stringify"? That will ensure a smooth transformation to a string and you can then use JSON.parse to get out the object you sent. From my experience with black screen WebRTC, I sense a dirty SDP payload.

而不是使用“decodeURIComponent”为什么不尝试“JSON.stringify”?这将确保平滑转换为字符串,然后您可以使用JSON.parse来获取您发送的对象。根据我对黑屏WebRTC的经验,我感觉到一个脏的SDP有效载荷。
