使用表达编码器传输网络摄像头或屏幕截图时减少延迟

Question

我有 10 秒的延迟，我需要实时或至少 1 秒。它不通过互联网。是否可以减少 WPF 中的缓冲时间？

服务器代码：

            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();
