Cameras Fail on Synology NAS

[futandrew]

I saw this documentation from HomeAssistant https://www.home-assistant.io/integrations/nest#camera which supports some cameras stream using WebRTC protocol. I'm wondering if this plugin can support this. Because this plugin has the ability to use HKSV, and believe this will be better if streaming is possible. Thanks/

[potmat]

I'm not sure what you mean. This plugin supports the latest generation of Google Nest cameras, which use WebRTC.

[futandrew]

Currently, the camera does not live stream videos, instead only nest home blue logo is shown. According to your readme, this is just a placeholder. However, using the homeassistant plugin which I shared above, it can stream/live stream the camera feed real time.

[potmat]

1. If you see the Nest blue logo that's a generation one camera which uses RTSP not WebRTC
2. What happens when you click/press on the camera to view the stream?

[futandrew]

1. It should be able to use the WebRTC protocol since I can use it successfully with the mentioned addon.
2. If I try to view the stream, it will fail and the log will display [homebridge-google-nest-sdm] FFmpeg exited with code: 1 and signal: null (Error) My Camera

[potmat]

If you have a generation one camera it does not use the WebRTC protocol, ever. Nor is there any way to force it. Generation two cameras use WebRTC. This plugin supports both.

If you enable debug mode we should be able to see more info about why the stream is failing.

[futandrew]

haha sure if you insist i am making things up. I surely happy to debug it later and share more information.

"haha sure if you insist i am making things up"

Please refrain from such language in the future.

Yes Home Assistant can use WebRTC, so can this plugin. Which streaming method a Nest Camera uses depends on which type of Nest Camera it is. You can see from the documentation here https://developers.google.com/nest/device-access/traits/device/camera-live-stream that the older cameras use RTSP streams and the newer cameras use WebRTC streams, and that they are not interchangable.

[futandrew]

I'm sorry if you are sensing anything that was not intended. All I want to do is to emphasize the fact I encountered.

As follows, please see the debug log. I masked out some token information with ***, I hope that won't affect the troubleshooting.

I crosschecked with HomeAssistant again today, and it is still working fine with live streaming. I want to stick with this home bridge plugin is because this is the only addon I can find which supports HKSV.

Thanks for your help! And again, my apologies for any misunderstanding in my tone.

The problem is here

[2/27/2023, 8:00:44 PM] [homebridge-google-nest-sdm] [error] Unrecognized option 'srtp_out_suite'.

Looks like the problem is whatever device you're using has ffmpeg 4.1, which is very out of date. Here is a thread about using a Synology NAS with exactly the same problem, possibly you're using the same setup?

[futandrew]

Thanks for the quick response. I followed that article and updated ffmpeg in Synology. Also, I noticed you posted an update with ffmpeg. So I reinstalled this plugin again. Now it is showing a more weird error with "Server returned 404 Not Found My Camera" now...

I tried to delete all projects on the Google API and Device Access Console and followed the step by step setup again, but it is not helping :(

Provide some logs from around when the issue happens.
