为什么录音文件的大小为0Kurento记录文件大小为0，为什么

-rw-r--r-- 1 kurento kurento 0 May 2 02:27 recorder1.webm 
-rw-r--r-- 1 kurento kurento 0 May 2 02:27 recorder2.webm

音频流如下。

　　　　　　　　 　　------>recorderEndpointA 
　　　　　　　　　　| 
Peer A <--------->RtpEndpointA<==>RtpEndpointB<---------->Peer B 
　　　　　　　　　　　　　　　　　　　　　　| 
　　　　　　　　　　　　　　　　　　　　　　　--->recorderEndpointB

程序如下。
- 创建mediapipeline
- 创建两个RtpEndpoints
- RtpEndpointA连接RtpEndpointB
- RtpEndpointB连接RtpEndpointA
- 创建两个RecorderEndpoints
- RtpEndpointA连接RecorderEndpointA
- RtpEndpointB连接RecorderEndpointB
- RecorderEndpointA记录
- RecorderEndpointB记录

因此，说话是正常的，但记录rding文件大小为0.

服务器的日志如下。

你有没有在记录器上调用'stop'？ – igracia

当我呼叫停止操作时，出现错误日志，“stop（）错误：已处于停止状态” – Hone

您可以共享代码的相关部分吗？如果你按顺序做事情，你会得到这个信息很奇怪。 – igracia

我们已经使用Kurento在Pipe供电在Chrome中的WebRTC视频录制。

我们也遇到了0字节的录像问题。到目前为止，我们已经确定了2个原因：

  1. TURN/STUN协议是由像TunnelBear一些VPN的阻塞（因为this）因此没有ICE候选人迄今发现的用户。我们的第一个测试版本没有考虑到这一点。
  2. 用户能够在不与Chrome的允许/阻止摄像头权限对话框交互的情况下开始录制。

嗨，对不起，但我也面临着ICE考生的一些问题，你能否告诉我更多关于ICE考生的相关问题，你是否执行过ICE重启？如何与Kurento Utils JS怎么可能？我面临同样的问题 –

+0

当没有找到ICE候选人时，我们只会显示一条信息消息。重新启动ICE可能会在某些角落案例中产生新的候选人（例如，在我们的案例中禁用了TunnelBear之后），但我们没有使用它。 –

那么你们是如何在ICE候选人失败的情况下使用它们呢？ –

谢谢大家。 Kurento只能作为音频媒体服务器。当我创建recordEndpointer时，mediaProfile未设置。但是，mediaProfile应设置为“WEBM_AUDIO_ONLY”。现在它可以工作。

我在这里发布了一个答案，在这种情况下，任何人在这里想知道发生了什么。它是非常重要的，RecorderEndpoint知道正在使用的媒体容器配置文件。我的问题是，我在开发时关闭了前端媒体限制的音频。 RecorderEndpoint需要通过传递正确的MediaProfileSpecType来了解这一点。

this.recorder = new RecorderEndpoint.Builder(pipeline, RECORDING_PATH + roomName + '_' + name + RECORDING_EXT) 
    .withMediaProfile(MediaProfileSpecType.WEBM) 
    .build();

只需上的音频前端义无反顾固定它，但你也可以参考包含在有Kurento团队已经根据某些媒体的约束容器逻辑连接其他教程代码。

我正在设置正确的媒体配置文件后，看麦克风/凸轮存在和'MediaStreamTrack.readyState'（它告诉你，如果权限已被授予和设备工作），我仍然得到0kb文件。库伦托6.6.1。根据Kurento的日志，这些文件没有收到任何声音输入（即使我们的客户端上的JS代码检测到话筒活动，K媒体日志中缺少'Media Flowing in pad default with type audio'）。 –

我会仔细检查你传递给'kurentoUtils.WebRtcPeer.WebRtcPeerSendrecv'的媒体约束。 – Throttlehead
