Camera Stream No Longer Works

[DevDylanB]

The problem

I'm assuming when the integration polls the api for the sensor data it is assuming that the camera stream is on the same port at the Octoprint instance. For those not running their instances on a Raspberry pi this typically isn't the case. I'm running MJPG streamer on ubuntu server. The stream works great in Octoprint, but home assistant fails to retrieve the correct port. My octoprint instance runs on :5000 while my camera stream is on :8080, but the set up wizard doesn't get that information. So, the camera entity is stuck on state Idle while the feed says, "Preview of the octoprint camera".

Using a generic camera will show the stream snapshot, but fails to render the live stream.

What version of Home Assistant Core has the issue?

2023.1.0

What was the last working version of Home Assistant Core?

2022.12

What type of installation are you running?

Home Assistant OS

Integration causing the issue

Octoprint

Anything in the logs that might be useful for us?

Additional information

I have deleted the integration several times as well as multiple reboots and defining the camera manually in camera.yaml If this is an error on my end I apologize in advance, but my camera stream was working for days up until now. If it is an error on my end, anything ideas would be greatly appreciated.

Hey there @rfleming71, mind taking a look at this issue as it has been labeled with an integration (octoprint) you are listed as a code owner for? Thanks!

Code owner commands

Code owners of `octoprint` can trigger bot actions by commenting: - `@home-assistant close` Closes the issue. - `@home-assistant rename Awesome new title` Change the title of the issue. - `@home-assistant reopen` Reopen the issue. - `@home-assistant unassign octoprint` Removes the current integration label and assignees on the issue, add the integration domain after the command.

Can confirm that adding a MJPEG camera through the official integration works. So it seems to be something regarding the stream URL being different. I removed haproxy on my linux server just to make sure that wasn't causing issues, but the camera feed was still dead in the Octoprint integration. I also attempted to use haproxy to forward Octoprint and the camera stream to port 80 (in the event the setup wizard was assuming that both would be on the same port). That was also unsuccessful.

Could you login to your octoprint instance then navigate to /api/settings and paste either the webcam portion of it or the entire blob(This may be large depending on what you have enabled)?

I just ended up giving the entire thing. The keyword "stream" was scattered throughout so figured I'd not skip over anything.

[rfleming71]

Perfect, thanks for adding the info. The underlying lib is making a bad assumption around the stream url. Will get working on a fix for that shortly.

[DevDylanB]

Bug squashed, thanks for being awesome!

Hey, i recently ran into the same problem. My Octoprint instance is running on docker on a second server, meaning that i have to use full http string to access it http://192.168.1.31:5001/?action=stream It work fine when i access it from the web UI of octoprint, but for some reason, Home Assistant integration get the camera as inactive even though the API return the good url. (streamUrl: "http://192.168.1.31:5001/?action=stream")

I'm running into the same issue. I have two instances of OctoPrint running on a Pi. To get the integration to see the 2nd instance, I had to change the UUID in /home/pi/.octoprint2/config.yaml to a unique one (it was the same as the 1st instance, from when I copied the config files). Once I did that, HA found the 2nd instance easily. I'm pretty sure it's the actual 2nd instance of OctoPrint because the first one has over 20 entities and the 2nd one has less than 15.

The webcam on the first instance works. On the 2nd instance, I can see there is a webcam, but I don't get a video stream. On my Pi, the first OctoPrint instance uses port 5000 for the main instance, also, I can use 172.16.7.21/prusa to see the first instance. The webcam is at port 5001. With haproxy, that also can be seen at 172.16.7.21/prusacam.

The 2nd instance uses port 5010 and, for the 2nd webcam, port 5011. The path haproxy uses for those is 172.16.7.21/e3p and the camera is at 172.16.7.21/e3pcam.

It looks to me like I'm dealing with the same issue here. I just updated HA today (Feb 5 2023) and just added the 2nd integration of OctoPrint today, too. (If the date on the post is different, I'm posting after midnight.) That means I'm probably on the latest versions and I think my problem is that dealing with a 2nd instance AND a 2nd webcam on the same Pi is not something that has been run into a lot with usage from HA, yet. I'm guessing there's no way, at this point, to tell the integration where to look for that 2nd webcam in that 2nd instance.

@MartinHjelmare:

Closing this as completed in 88052 - does that mean if I specify a full absolute URL, then I can see the 2nd webcam?

[MartinHjelmare]

Sorry I don't know any Octoprint specifics. The merged PR will go out in 2023.2.5.
