WebRTC remoteVideo元素不断加载

Question

您知道问题可能在哪里吗？ localVideo元素可以正常工作，但是我在两台计算机上获得的remoteVideo元素都是（无限循环/加载），带有...

• networkState 2 = NETWORK_LOADING - browser is downloading data
• readyState 0 = HAVE_NOTHING - no information whether or not the audio/video is ready

我检查了所有内容：

✔️每个对等连接（pc）都具有来自其他对等方的要约或应答的正确 remoteSDP 。

✔️ remoteVideo元素具有。 。

• Autoplay == true
• Muted == false
• Paused == false
• Disabled == false

✔️ ICE 似乎可以解决，因为每台PC都有。 。

• iceConnectionState: "new"

• iceGatheringState: "complete"

✔️我的代码中的最后一个命令是。 。

• remoteVideoElement.srcObject = e.streams[0];（由先前声明的pc1.addEventListener('track', gotRemoteStream);触发）

✔️当我打开控制台并尝试手动将PC的remoteStream附加到视频元素时，什么也没有发生，如下所示：

• remoteVideo.srcObject = pc1.getRemoteStreams()[0];

以下是我的两个console.log()组合：

Answer 1

  

ICE似乎可以解决问题，因为每台PC都有。 。

iceConnectionState: "new"

如果iceConnectionState仍然是新的，则ICE不能正常工作。

它仍然是新的，甚至没有检查表明没有远程候选冰添加到连接中。 This blog post解释了使用chrome：// webrtc-internals找出原因的方法。
