Hikvision IPC-D140H - Camera laggning behind
Hi
Im relatively new in homebridge.

I'v installed the camera-ffmpeg plugin and added my 2 Hikvision IPC-D140H cameras like the configuration below. 
The feed works fine if I view the rtsp feed via VLC. But when viewing it via HomeKit every second of the camera feed is display 3-5 seconds in the app. So the feed lagg behind pretty soon. I can see this on the clock in the camera feed.

I have tryed play around with FPS, bitrate, codec and so on without success. 
I don't get any errors in the logg in Homebridge.

Can anyone point me in the right direction on what I can troubleshoot more?

HomeBridge running on RPI config:

            "cameras": [
                {
