# Live Streaming Issue

### Describe the live streaming issue

It was working fine, but with lastest set of updates it now fails on streaming (and I also don't get static picture)
Fails to even start.In Home App it generates a "No Response.  This camera is not responding"

Homebridge : 1.2.3
Ring Plugin : 9.9.0
Homebridge Confix UI X : 4.27.1
Homebridge Camera FFMPG : 3.0.3

(I use the FFMPG for two raspberry pi cameras)



### Screenshots/Logs

It immediately throws an error log when trying to start.  Shown below:

### Recommended solution

Looks like code issue.  Can't find a property...

### Environment

 - Ring Camera: Pro - Hardwired
 - OS: Raspiban - From Homebridge Disk image install.
 - Node.js: Whatever comes with Hombridge Disk Image.  This machine ONLY runs Homebridge
 - NPM: Ditto
 - homebridge-ring :9.9.0
 - homebridge : 1.2.3


### Network Environment

I doubt it's anything in network... it looks like code issue.  Fairly simple wifi network using Unifi equipment.
It was working until the latest update, so that makes me believe it's a code issue.  Or dependency clash.
