"failed: 404 Not Found" on Stream Startup
Sometimes when attempting to view a camera stream an error like

`[homebridge-google-nest-sdm] [rtsp @ 00000280aed0e780] [error] method DESCRIBE failed: 404 Not Found`

Or something like:

`[homebridge-google-nest-sdm] [error] rtsps://<stream url>: Server returned 404 Not Found Camera
[23/11/2021, 08:57:34] [homebridge-google-nest-sdm] Camera
[23/11/2021, 08:57:34] [homebridge-google-nest-sdm] FFmpeg exited with code: 1 and signal: null (Error) Camera`

Intermittently the SDM API seems to return 404 when attempting to access the DESCRIBE method of RTSPS streams.  The cause and resolution are unknown at this time.

I am attempting to contact Google about the issue.

If there are any fffmpeg experts out there who could help it would be appreciated.
