FFmpeg videoanalysis process exited with error! (null) - [tcp @ 0x5590256e30] Port missing in uri
Hey,

Have read some issues with Reolink RLC-820A and RLC-410W cameras and no messages if they were succesfull to setup the cameras. I have followed the syntax but nothing want to work.

Homebridge is installed on a Raspberry Pi 4, 64-bit with latest raspian.
