reduce latency when streaming webcam or screencap with expression encoder

I've got a delay of 10 seconds, I need real-time or at least 1second. It doesn't go through the Internet. Is it possible to reduce buffer time in WPF?

Server code:

            job = new LiveJob();
        Collection<EncoderDevice> devices = EncoderDevices.FindDevices(EncoderDeviceType.Video);
        EncoderDevice device = devices[0]; 
        LiveDeviceSource source = job.AddDeviceSource(device, null);
        source.ScreenCaptureSourceProperties = new ScreenCaptureSourceProperties
                                                   {
                                                       CaptureCursor = true,
                                                       CaptureLargeCursor = false,
                                                       FrameRate = 6,
                                                       CaptureLayeredWindow = true,
                                                       Height = 600,
                                                       Width = 800,
                                                       Left = 0,
                                                       Top = 0,
                                                   };
        job.ActivateSource(source);
        // Finds and applys a smooth streaming preset
        job.ApplyPreset(LivePresets.VC1256kDSL16x9);
        // Sets up variable for fomat data
        var format = new PullBroadcastPublishFormat {BroadcastPort = 8080};
        job.PublishFormats.Add(format);
        job.StartEncoding();
