[error] Empty H.264 RTP packet
First of thanks for all the work! I just tried it with my google nest doorbell (akku) and it seems to work as expected.
That said I see a lot of these logs:

```
1|homebridge  | [1/24/2022, 3:21:22 PM] [homebridge-google-nest-sdm] [sdp @ 0x80cc59000] [error] Empty H.264 RTP packet Flur Doorbell
```

I wonder if there is anything wrong with my setup or if its expected ?
