Unable to get camera working in docker

[spuder]

First of all, thank you so much for making this software. I've tried HomeAssistant, OctoEverywhere but they just don't give me quite what I'm looking for. This software looks perfect!

I'm finding that I am unable to stream video from my a1 mini in docker compose.

Is LAN LiveView an X1 only feature? I've searched though the menus and I'm unable to find this setting on an A1 Mini. I suspect it might be an X1 only feature. Please correct me if I'm wrong. Based on the fact that other software is able to stream the webcam feed I suspect the problem is with my configuration, not the printer.

There is also a bambu-web-env.txt

I'll happily add documentation to help others as it seems I'm not the first one running into this problem.

Do you have any ideas what I am missing?

Yes LanView is an X only thing (proper camera video stream).... a/p/s models uses mjpeg.... basically custom auth and then a stream of sequential jpegs...

I havent had a need for it, but it would be possible to build 'middleware' that grabs the mjpeg stream and make it available via mediamtx using ffmpeg

[spuder]

Thanks for the response. I can add some documentation clarifying that only X1 users need to enable LanView.

So am I understanding that it's not possible to get the video (really just images) from an A1/P1 printer?
