[Bug] EXTERNAL: P2S Camera unreliable in home assistant. Workaround - use webrtc card or go2rtc to improve reliability.

[tst-038]

Home Assistant Version

2025.3.4

Bambu Lab Integration Version

v2.2.10-beta3

Describe the bug

The camera is streaming, and can be enabled disabled however the stream does not load properly.

I have tried other versions, restarted printer, reconfigured etc etc nothing worked.

To Reproduce

P2S just didnt work from the get go

Expected Behaviour

Machine go boop boop

What device are you using?

P1S

Diagnostic Output

diagnostics

Log Extracts

No response

Other Information

I'm using a P2S! second gen!!!! (No device tag available yet)

[tst-038]

Update, it seems like the rtsps feed doesnt work, maybe the link changed?

Same issue here, the P2S camera feed shows no image.

Can I get a diagnostics log and a debug log of the integration initializing please.

I guess, it's same same Problem, wie discussed at #1602 etc.

A workaround can found here: #1602 (comment)

Just discovered that you can tell home assistant itself to use an external go2rtc instance. And that magically enables the generic camera to support webrtc and so suddenly you get low latency video playback.

After spending tons of time going in circles with chatgpt, all I ended up doing was folllowing the self hosted setup instructions here which is just a quick configuration.yaml edit:
https://www.home-assistant.io/integrations/go2rtc/

My generic camera then immediately switched to (near zero latency) under the hoods instead of the higher latency (3 second or 8 second latency depending how the go2rtc stream was configured).

Adding the camera with go2rtc also does not work for me yet, i also could not open the stream with vlc or ffplay, tried other ports, access codes from BambuStudio.conf for the serial number,

streams:
  p2s:
    - rtsps://bblp:xxxxxxxx@192.168.1.xx:322/streaming/live/1

i can see the stream in the bambu studio and it can also stream somehow with a streaming option, but it seems the printer camera feed endpoint may be different?

I dont use lan only mode, its online connected device, is that the issue here?

@Evaske
Do you happen to run HA in some kind of sandbox env?
I do and there the covers do not work presumably because it cant write to the hardcoded /config folder (opening an issue for this)

However as soon as I try running via a docker container on my laptop it works, (unfortunately camera is still broken)

bambu_lab_diagnostics.json

Other than the error from #1634 I dont really have anything else in the logs

Your issue is that you haven't turned on lan_live_view support on your printer. I plan to have the integration raise an 'issue' when people set up the integration and haven't done that. Lan_live_view (may be named a little differently) is entirely independent of lan mode - it just turns on the local video stream support.

@Evaske Please create a separate issue with diagnostic and debug logs for a repro of it failing to load the cover image.

Deleted the comments that are for that and not related to the P2S camera issues.
