Question

基于魔镜示例我尝试将结果MP4保存到文件中。视频保存得很好，但音频静音。

如何在kurento中启用音频流？

更新 创建端点和管道的服务器代码：

 ...
 MediaPipeline pipeline = kurento.createMediaPipeline();
 ...

String createWebRTCEndpoint(MediaPipeline pipeline, String uri, String exchange, String sdp) {
    RecorderEndpoint rep = new RecorderEndpoint.Builder(pipeline, uri)
        .stopOnEndOfStream()
        .withMediaProfile(MediaProfileSpecType.MP4)
        .build();
    WebRtcEndpoint webRtcEndpoint = new WebRtcEndpoint.Builder(pipeline)
        .build();
    webRtcEndpoint.connect(rep);
    rep.connect(webRtcEndpoint);
    rep.record();
    final String result = webRtcEndpoint.processOffer(sdp);
    synchronized (pipelinesAcc) {
        pipelines.put(exchange, new Tuple<>(pipeline, new Date()));
    }
    return result;
}
