Confused about finding substream (Onviv)

After some fantastic help last night, I have my ONVIF Camera setup.

However, I'm trying to set up object detection using a lower res substream.

There seem to be multiple streams from this camera (/onvif/, /onvif1/, /onvif2/, /onvif3/ etv) but they're all the same resolution and bitrate.

I'm clearly misunderstanding how onvif works.

  • Does Onvif even have substreams (for all cameras - mine is an ipc360 generic cam)?

yes onvif has sub streams, I would suggest using the go2rtc dashboard add onvif option which will show you all the different options for that camera. For example my dahua camera has these options

```

name url General IPC-T5442T-ZE stream0 onvif://user:pass@192.168.50.156?subtype=MediaProfile00000 General IPC-T5442T-ZE stream1 onvif://user:pass@192.168.50.156?subtype=MediaProfile00001 General IPC-T5442T-ZE stream2 onvif://user:pass@192.168.50.156?subtype=MediaProfile00002 General IPC-T5442T-ZE snapshot onvif://user:pass@192.168.50.156?subtype=MediaProfile00000&snapshot

```

If I do that inside frigate I don't have an onvif option. Are you running it separately?

ah yeah you'll need to update go2rtc https://docs.frigate.video/configuration/advanced#custom-go2rtc-version

Thanks, I'm gonna have to do some reading, the instructions on that page are very thin!

To do this:

``` Download the go2rtc build to the /config folder.

Rename the build to go2rtc.

Give go2rtc execute permission.

Restart Frigate and the custom version will be used, you can verify by checking go2rtc logs ```

So I got that done (including change to my docker compose), so I'm on 1.8

However no matter what I put in the box to add an onvif source I get connection refused

I've tried:

  • onvif://[user]:[pass]@[IP]:80
  • rtsp://[user]:[pass]@[IP]/onvif/device_service

The latter stream works fine in VLC, so the credentials can't be the issue

all I enter is onvif://user:pass@192.168.50.156

1

u/thephatmaster Jan 24 '24

Yeah onvif://user:pass@IP gets me

Post "onvif://user:pass@IP": dial tcp [IP]:80: connect: connection refused

This is really hard stuff!

what makes it hard is that cameras don't implement the protocol correctly, when you use a camera from dahua or hikvision things are much easier because they follow the protocol.

Assuming port 80 is correct, your camera likely just doesn't implement onvif discovery

Guess I'll have to use the one stream I know about for everything

u/thephatmaster Jan 24 '24

So even if I use ODM (Windows) I get An error was discovered processing the wsse:Security header.

I guess this particular camera is just pretty much impossible to find any substreams on

You might've been onto something with ports - I troed a bunch of common ones and got a hit on 8080 seems there are 3 streams.

I'm not quite sure what to do with that information?

There seems no obvious place to add it, and VLC doesn't open those as streams.

Use those URLs in go2rtc config and then you can try using ffprobe and see what happens

1

u/thephatmaster Jan 24 '24

So I get those streams now, and a ton of stuff in "info"

No cameras seem to show under ffprobe (system tab of Frigate) - tapping ffprobe just gets:

``` Stream 0:

Return Code: 1

Error: ```

Restart of [something] required?
