Sigsegv with tapo protocol

hmlnarik commented 5 months ago

Thank you for the go2rtc product!

I hope you could help me with crash when opening webrtc.html with the following source:

streams:
    rtsp.sha256: 
        - rtsp://x:hash@192.168.a.b/stream1
        - tapo://x:hash@192.168.a.b

Could you please help me to if that could be a configuration issue? Running go2rtc using docker image via podman. Plain rtsp stream works perfectly.

I have a number of IP addresses. For simplicity, the relevant ones have been replaced with `192.168.a.` below: `192.168.a.cam` for camera, `192.168.a.browser` for browser, and `192.168.a.go2rtc-host` for the RPi hosting go2rtc.

Do you have developer skills? I think this is place of problem https://github.com/AlexxIT/go2rtc/blob/b08b88357eb7903bb53506e1cf9f99dd7db24f1a/pkg/tapo/client.go#L284

curl -v --request POST \
  --url http://192.168.1.123:8800/stream \
  --header 'Content-Type: multipart/mixed; boundary=--client-stream-boundary--'

go2rtc/pkg/tapo/client.go

Yup, that might be right as there is no WWW-Authenticate header:

curl -v --request POST \ --url http://192.168.1.123:8800/stream \ --header 'Content-Type: multipart/mixed; boundary=--client-stream-boundary--'

This returns:

Connection gets closed in about 10 seconds.

Something new without auth and none password. @JurajNyiri have you saw this?

@hmlnarik try to:

Update camera firmware (skip if none)
Reset camera and add it to Tapo app again
Open live stream via Tapo app
Open again via go2rtc

JurajNyiri commented 5 months ago

I haven't seen this yet. If it is something new it will come up for recordings for Tapo integration so we will see. We need to know what is the current firmware user uses.

hmlnarik commented 5 months ago

@AlexxIT I am not using Tapo app, and I tried go2rtc for that reason. Would it be possible to not authorize if the WWW-Authenticate is not present?

JurajNyiri commented 5 months ago

That must be the reason. @hmlnarik never configured the camera through tapo app.

AlexxIT commented 5 months ago

You really didn't connect the camera to the app? Not even once? Where you get user and password (hash)? And how you connect camera to WiFi?

JurajNyiri commented 5 months ago

I think he might have used https://github.com/JurajNyiri/pytapo/issues/24 . I am torn on supporting this in pytapo and tapo integration for many reasons.

hmlnarik commented 5 months ago

I used similar approach to that described in https://github.com/JurajNyiri/pytapo/issues/24 to connect to wifi.

I'll try to just skip adding Authorization header, or craft it somehow. Thanks for the help so far.

AlexxIT commented 5 months ago

Well. You can try to fix this yourself. I don't know when I will have time to do this trick with my camera.
