Video lagging....
<!-- You must use the issue template below -->

**Describe The Problem:**
After adding one of my HIKVision cameras into Homebridge (running on my Synology NAS) I'm seeing the thumbnail looking like the bottom half of the video is streaked. When I tap on the camera image I get a 'no response' message.

**To Reproduce:**

I've played with the various configuration options but nothing seems to make a difference
