[Bug] EXTERNAL: Error opening camera streams due to X1 firmware issues

[bubbleytea]

Describe the bug

Camera streams stopped working and I see this error in the logs:

2023-09-19 21:17:18.749 ERROR (stream_worker) [homeassistant.components.stream.stream.camera.x1c_****_camera] Error from stream worker: Error opening stream (ERRORTYPE_5, I/O error) rtsps://****:****@192.168.1.168/streaming/live/1

Camera streams time out:

They were working before when I first set up the integration.

To Reproduce

Install integration and add devices. Eventually the streams just stop loading.

Expected Behaviour

Camera stream loads

What device are you using?

X1C

Firmware Version

01.06.03.00

Home Assistant Version

2023.9.2

Component Version

1.5.0

Log Extracts

2023-09-19 21:17:18.749 ERROR (streamworker) [homeassistant.components.stream.stream.camera.x1c*_camera] Error from stream worker: Error opening stream (ERRORTYPE_5, I/O error) rtsps://**:****@192.168.1.168/streaming/live/1

Other Information

I don't see any other errors in the logs. Is there anything else I can do to help debug?

[greghesp]

Has the IP of your printer changed by any chance?

[bubbleytea]

Has the IP of your printer changed by any chance?

No, I checked and the IPs of all the printers are still the same. All of the other sensors are working properly (I'm assuming those would be broken too, if the IP changed?).

[greghesp]

Ah yeah you're right. I got the logic mixed up with something else I did.

Can you access the stream via VLC?

[IIDemoniaKII]

Hello,

I have the same problem.

Error from stream worker: Error opening stream (EXIT, Immediate exit requested) rtsps://:@us.mqtt.bambulab.com/streaming/live/1

[greghesp]

Ohhh ok, I know the cause of this now. The URL is populated from the config flow, not the MQTT. Will revert

[IIDemoniaKII]

Thank you for your work !

[greghesp]

Can you try the latest pre-release please: https://github.com/greghesp/ha-bambulab/releases/tag/v1.7.1-dev1

[IIDemoniaKII]

Hello,

Still does not work.

Tried to install locally, without success.

I am attaching error logs, but I am not sure that they correspond to this problem.

Oops, minor issue. New dev release: https://github.com/greghesp/ha-bambulab/releases/tag/v1.7.1-dev2

You might need to reload the integration

[IIDemoniaKII]

Hello, I can't find the version on HACS.

[greghesp]

Hello, I can't find the version on HACS.

Have you go the Beta toggle ticked?

[IIDemoniaKII]

Yes, i see v1.7.1-dev1

[greghesp]

Yes, i see v1.7.1-dev1

Odd. I just checked my production instance and it's there. Maybe try toggling it? Sometimes its in the drop-down, but you have to select off if and then back into it for it to select

[IIDemoniaKII]

I will try to uninstall completely and download again

[IIDemoniaKII]

No, it doesn't appear

[IIDemoniaKII]

[greghesp]

Ahhhh, I'd created the tag but not the release. Oops! Try again now

[IIDemoniaKII]

Upload the file directly to home assistant, unfortunately it still doesn't work

[greghesp]

Oh - you don't have RTSP enabled on your printer. After the @ sign in that URL should have the IP address, but its reporting disabled instead

[IIDemoniaKII]

My fault, I forgot to reactivate live. It works, thank you very much! Beautiful evening

[greghesp]

Seems I've also got the same issue as OP 2023-10-01 11:19:06.584 ERROR (stream_worker) [homeassistant.components.stream.stream.camera.x1c_00m00a280103660_camera] Error from stream worker: Error opening stream (ERRORTYPE_5, I/O error) rtsps://****:****@192.168.1.64/streaming/live/1

I'm not sure this is an issue with the integration, as VLC cannot access the stream either.

@bubbleytea - Have you got Timelapse on? I've never had this issue before, and I've just turned timelapse on and now have this issue

[IIDemoniaKII]

Hello,

New problem it seems, my timelaps is activate

I'm also getting this issue as well. It's nothing to do with HA from what I can tell, as I'm also unable to access the stream from VLC. Must be a bug in the firmware

Double check that its enabled on your printer. This error is the printer not returning a stream, usually because its disabled

[mateuszdrab]

Lan View is enabled - I was just playing with the local instance of Bambu Studio and figured out I can get a cloud stream on demand by running bambu_source and piping it into ffmpeg which is what the studio does. bambu_source takes a token from a file called url.txt which I presume is populated from some API call the studio does.

Printer is in cloud mode - integration is connected using cloud mode as well

[greghesp]

Yep, that cloud stream has nothing to do with rtsp, and its a proprietary streaming protocol.

Can you try disabling and enabling it on your printer?

[mateuszdrab]

I've done that but it made no difference. I can't see any rtsp/rtsps ports open on the printer. I did find that the FTP server is available, I think this could be utilized to integrate with the media browser to provide users with timelapse video access directly from HA.

Regarding the camera, does anyone with X1C actually got it working? If so, I'll just go and check things with Bambu support.

I was thinking of using the proprietary Bambu source executable to provide the stream to home assistant via rtp for now, hence my attempts at working out how it works.

I just figured out what happens behind the scenes when you Go Live from Bambu Studio. If you enable that switch there, you can access the camera via ftp://localhost:1234 which is the result of Bambu Source bring executed and piping the output into ffmpeg which is then made to listen on port 1234. However, the token in the url.txt file which is needed to start bambu source isn't valid forever so I'd need to figure out how that token is generated before the above steps make sense.

That's purely for their "go live" functionality that allows you to stream to Twitch or whatever. All that does is take the proprietary stream, and then re-broadcasts it on a local IP address from your machine.

Sometimes. I've already raised it with them and they are aware and have found the bug

Awesome, I hope the fix makes it into the new upcoming firmware.

[brantje]

I get the same error, but my URL looks very different:

Error from stream worker: Error opening stream (PROTOCOL_NOT_FOUND, Protocol not found) ://bblp:4xxfxxe@disable

I suppose re-adding the integration will solve this?

What version are you on? On the latest dev version, should be able to see in the logs

homeassistant | 2023-12-22 14:13:17.461 DEBUG (MainThread) [custom_components.bambu_lab] Camera RTSP Feed is rtsps://bblp:<access_code>@192.168.1.64/streaming/live/1

@disable means you don't have lan view enabled.

[AdrianGarside]

Fix to make Camera entity disabled when lan view is not enabled:

325

[AdrianGarside]

I'm going to mark this as won't fix for now as there are no known issues in the integration handling of the rtsp feed - all indications are that the remaining problems are all bugs in the firmware implementation on the Bambu side.

[mateuszdrab]

Are there any updates on the support case with Bambu Lab?

Lastest firmware came in recently and the issue still exists.

[anoblet]

I can get a camera stream after first boot on an X1C using HA. After that it drops off. I'm not sure when, or why, though diffing the i/o could provide a clue. Does the FW just drop multiple streams? Does it fallback on trusted domains?

Anyways please take some time for the holidays, we'll always be here :)

[AdrianGarside]

The RTSP support in the firmware is just very buggy unfortunately.

[anoblet]

It hasn't bothered me much, it seems like a finicky problem to solve. Everything else works great :)

[jmwaldrip]

I was having the same right after I upgraded to firmware 1.7.01.00. I played with it for a while, but after I hard rebooted the printer it started working.

I am having some timestamp differences errors but it seems to be working well.

I will add another comment if it stops working or has any issues. So far seems pretty stable.

I am also starting to play with WebRTC and streaming it through that to see if it makes a difference.

[AdrianGarside]

What I’m finding is that with webrtc and pointing both my production and test instance of home assistant at the same go2rtc instance then I have a reliable connection. But if I restart home assistant (and with my docker based setup that restarts go2rtc) then the connection is broken until I restart the printer.

[AdrianGarside]

While when I had two separate go2rtc instances the connection I think was not reliable even if I didn’t restart my production home assistant instance but I’m not certain.

[jmwaldrip]

Oh interesting, I haven't had time to try the a webrtc server yet. What are you using for the docker container? I was thinking of throwing it on my k8s cluster.

[jneilliii]

go2rtc is one I've used outside of HA before, but think it's actually bundled in HA too IIRC
