Kurento記錄文件大小爲0，爲什麼

爲什麼錄音文件的大小爲0Kurento記錄文件大小爲0，爲什麼

-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

音頻流如下。

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

程序如下。
- 創建mediapipeline
- 創建兩個RtpEndpoints
- RtpEndpointA連接RtpEndpointB
- RtpEndpointB連接RtpEndpointA
- 創建兩個RecorderEndpoints
- RtpEndpointA連接RecorderEndpointA
- RtpEndpointB連接RecorderEndpointB
- RecorderEndpointA記錄
- RecorderEndpointB記錄

因此，說話是正常的，但記錄rding文件大小爲0.

服務器的日誌如下。

你有沒有在記錄器上調用'stop'？ – igracia

您可以共享代碼的相關部分嗎？如果你按順序做事情，你會得到這個信息很奇怪。 – igracia

我們已經使用Kurento在Pipe供電在Chrome中的WebRTC視頻錄製。

我們也遇到了0字節的錄像問題。到目前爲止，我們已經確定了2個原因：

  1. TURN/STUN協議是由像TunnelBear一些VPN的阻塞（因爲this）因此沒有ICE候選人迄今發現的用戶。我們的第一個測試版本沒有考慮到這一點。
  2. 用戶能夠在不與Chrome的允許/阻止攝像頭權限對話框交互的情況下開始錄製。

嗨，對不起，但我也面臨着ICE考生的一些問題，你能否告訴我更多關於ICE考生的相關問題，你是否執行過ICE重啓？如何與Kurento Utils JS怎麼可能？我面臨同樣的問題 –

+0

當沒有找到ICE候選人時，我們只會顯示一條信息消息。重新啓動ICE可能會在某些角落案例中產生新的候選人（例如，在我們的案例中禁用了TunnelBear之後），但我們沒有使用它。 –

那麼你們是如何在ICE候選人失敗的情況下使用它們呢？ –

謝謝大家。 Kurento只能作爲音頻媒體服務器。當我創建recordEndpointer時，mediaProfile未設置。但是，mediaProfile應設置爲「WEBM_AUDIO_ONLY」。現在它可以工作。

我在這裏發佈了一個答案，在這種情況下，任何人在這裏想知道發生了什麼。它是非常重要的，RecorderEndpoint知道正在使用的媒體容器配置文件。我的問題是，我在開發時關閉了前端媒體限制的音頻。 RecorderEndpoint需要通過傳遞正確的MediaProfileSpecType來了解這一點。

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

只需上的音頻前端義無反顧固定它，但你也可以參考包含在有Kurento團隊已經根據某些媒體的約束容器邏輯連接其他教程代碼。

我正在設置正確的媒體配置文件後，看麥克風/凸輪存在和'MediaStreamTrack.readyState'（它告訴你，如果權限已被授予和設備工作），我仍然得到0kb文件。庫倫託6.6.1。根據Kurento的日誌，這些文件沒有收到任何聲音輸入（即使我們的客戶端上的JS代碼檢測到話筒活動，K媒體日誌中缺少'Media Flowing in pad default with type audio'）。 –

我會仔細檢查你傳遞給'kurentoUtils.WebRtcPeer.WebRtcPeerSendrecv'的媒體約束。 – Throttlehead
