I couldn't get RTMP to work on the Back Yard camera because the `ffmpeg`
process kept crashing:
```
ffmpeg.back_yard.clips_rtmp ERROR : av_interleaved_write_frame(): Connection reset by peer
ffmpeg.back_yard.clips_rtmp ERROR : [flv @ 0x5562090c8ec0] Failed to update header with correct duration.
ffmpeg.back_yard.clips_rtmp ERROR : [flv @ 0x5562090c8ec0] Failed to update header with correct filesize.
ffmpeg.back_yard.clips_rtmp ERROR : Error writing trailer of rtmp://127.0.0.1/live/back_yard: Connection reset by peer
watchdog.back_yard INFO : Terminating the existing ffmpeg process...
watchdog.back_yard INFO : Waiting for ffmpeg to exit gracefully...
```
I thought increasing the value of `--shm-size` argument for `podman`
would help, but even going as high as 1024 mebibytes did not resolve the
problem.
Ultimately, I decided that it is not really necessary to view the full
4k stream in real time. The back yard camera supports three streams, so
I set them all up for different roles. I briefly considered using a
single 1080p stream for both object detection and RTMP streaming, but
this consumed considerable CPU time, so I decided against it for now. I
may re-evaluate that option if I decide to purchase a TPU.
*nvr0.pyrocufflink.blue* hosts Frigate. It is deployed on a separate
subnet, for two reasons:
* To avoid streaming video from the cameras through the firewall
* To prevent any hosts on the LAN except Home Assistant from
communicating with Frigate, since it does not have any kind of
authentication or access control
