Issues with Pi Camera after fresh install and BTT PITFT50 | Mainsail | Page 1

Hey all 👋

I had been using MainsailOS for a while and decided to restart with a fresh image to update to bullseye after attempting a manual update and failing.

I have been able to get my config updated but after the re-image I have not been able to restore the webcam to a functional state.

I was initially using a PiCamera v1 but I have switched to a spare PiCamera v2 in an attempt to see if the module and or cables had issues but I am still struggling to get that working as well. I have tried using the legacy mode as well per some of the troubleshooting guides and that did not work either.

I have also removed and rebuilt crowsnest as I had seen that had fixed others issues but I am still stuck.

Maybe related, I am also using a BTT PITFT50 V1.0 and I needed to comment out dtoverlay=vc4-kms-v3d the boot config in order for the touch to work correctly:

# Enable DRM VC4 V3D driver
#dtoverlay=vc4-kms-v3d
#max_framebuffers=2

Anything I overlooked?

Even if I am using an imx219 now?

This seems strange to me:

Why is it pulling /dev/video0 instead of /dev/video31?

#

I can try legacy mode again I guess...

#

libcamera is able to see the device at the moment:

No idea, but it doesn't matter. Failed to start streaming: Input/output error is the problem with the klipperscreen

spiral lotus Apr 21, 2024, 8:57 PM

gaunt flower libcamera is able to see the device at the moment: ``` $ libcamera-hello --list-...

Yes, and what should that do now?

#

It's seeing it, but it cannot use it. Why? Because of the DSI screen

#

Just trust my intuition, I'm supporting that for over one year now and it's really annoying

gaunt flower Apr 21, 2024, 9:04 PM

#

🥳 FINALLY!!!!!

#

I had to switch it to MJPEG in the webcam settings as well but I finally have output.

#

Now to put all of the cables back in their place make sure that it still works.

Ustreamer got no webrtc. I will have to work on the docs in that regard a bit

gaunt flower Apr 21, 2024, 9:06 PM

I wonder why it was not working last night. Maybe it was because I tried this before rebuilding crowsnest.

mode: camera-streamer

You most likely forgot some setting inside the /boot/config.txt

spiral lotus Apr 21, 2024, 9:07 PM

#

gaunt flower `mode: camera-streamer`

That won't work with legacy stack

gaunt flower Apr 21, 2024, 9:08 PM

#

🤔 it works if the webcam is MJPEG but not WebRTC

I don't think you understand those services

#

How should a webrtc service, work with a mjpg stream?

#

It's like, if you want to order something in a language the waiter cannot understand

gaunt flower Apr 21, 2024, 9:10 PM

#

But the legacy stack is working with mode: camera-streamer in the config unless it is silently falling back to the old method.

spiral lotus Apr 21, 2024, 9:10 PM

#

You are the service and the waiter is the url

Nope, it's not working. I'm pretty sure of that

gaunt flower Apr 21, 2024, 9:10 PM

#

No, I get this, but that is not how the config is setup.

spiral lotus Apr 21, 2024, 9:10 PM

#

Send your log

spiral lotus Apr 21, 2024, 9:11 PM

#

gaunt flower No, I get this, but that is not how the config is setup.

In any way the used url would be wrong for webrtc. So even if you would have awebrtc stream available, you cannot use it like that

#

You have to talk to the waiter, that can understand you. For webrtc it would be /webcam/webrtc

gaunt flower Apr 21, 2024, 9:12 PM

#

Wait, could the URL have been my problem then?

spiral lotus Apr 21, 2024, 9:12 PM

#

Nope

#

It might have been a problem too, but the error in the log is clear

You can try if you want, but I can already predict the outcome ^^

Oh, you are right. It's working 🤔
Never got the legacy stack working with camera-streamer 😂

So it's possible that it might lag at some point

gaunt flower Apr 21, 2024, 9:16 PM

#

Well, I can switch to mode: ustreamer as well.

spiral lotus Apr 21, 2024, 9:16 PM

#

Did you try webrtc?

#

Maybe it was only webrtc with problems 🤷‍♂️

#

Here again the correct settings:

gaunt flower Apr 21, 2024, 9:19 PM

#

I'm trying now. It would be nice if the UI warned that was an incorrect setting.

spiral lotus Apr 21, 2024, 9:19 PM

#

How should it do that?

gaunt flower Apr 21, 2024, 9:20 PM

#

spiral lotus Maybe it was only webrtc with problems 🤷‍♂️

Yeah, WebRTC is not loading any screen.

spiral lotus Apr 21, 2024, 9:20 PM

#

It's impossible to check an url, if it's correct, as it might be possible that someone got a weird reverse proxy setup and put their webrtc under a different path

#

The only check is image or no image

gaunt flower Apr 21, 2024, 9:20 PM

#

If you cared.

📎 crowsnest-webrtc.log

spiral lotus Apr 21, 2024, 9:21 PM

#

But that's nothing the ui has to tell you, as you can see it on your own

gaunt flower Apr 21, 2024, 9:21 PM

#

spiral lotus Apr 21, 2024, 9:21 PM

#

Client removed: Remote description has no ICE user fragment.
That seems weird 🤔

#

camera-streamer isn't logging something special, so it's possible that it simply doesn't work, for whatever reason. I don't think that you local installation is bad somehow

gaunt flower Apr 21, 2024, 9:23 PM

#

spiral lotus How should it do that?

Maybe look for ?action=stream at then end of the URL when in webrtc mode?

spiral lotus Apr 21, 2024, 9:23 PM

#

I might test it tomorrow

spiral lotus Apr 21, 2024, 9:23 PM

#

gaunt flower Maybe look for `?action=stream` at then end of the URL when in webrtc mode?

What if someone has put the webrtc at that location, for any reason?

#

Those are hacky workarounds, for something that doesn't make sense.
If we think that further:
If there now would be ?action=stream you would print some kind of message with "this url is wrong check the docs". Now someone deletes only a few letters and maybe writes ?action=webrtc. There is now no message. So that means it's working? Ofc not, but some users, might think that

gaunt flower Apr 21, 2024, 9:26 PM

#

🤷‍♂️ It was just an idea.

#

Maybe the ?action= is a better key. I know very little about what the different URL formats are supposed to be but guidance for inexperienced users would be nice.

spiral lotus Apr 21, 2024, 9:27 PM

#

So the better solution would be to check for /webcam, then you got the problem with some weird reverse proxy maybe.
I think you get what I mean. I appreciate your intention to help, but it's sometimes not as easy, as it doesn't make sense, to do this for only one stream, and then maybe you got some error that makes problems with other special setups.
The easiest thing is: Is it working? Yes => good. No => you did something wrong, read the docs or ask for help

spiral lotus Apr 21, 2024, 9:28 PM

Where do you start and where do you end? What if someone rewrites it, then you got some "bug" that it says, not working but it's actually working.

#

You would have to do that for basically every service

gaunt flower Apr 21, 2024, 9:29 PM

#

I help out with OpenRGB as a dev so I am all about self supporting infrastructure. Now if I can only get users to read the readme that tells them what to do .....

spiral lotus Apr 21, 2024, 9:29 PM

#

But it's not possible for every service. So if the message is there, it's wrong, ok. But if it's not there, it doesn't mean working...

spiral lotus Apr 21, 2024, 9:30 PM

That's why we have our docs. Some user has no image? => log and screenshot of cam settings
wrong cam settings => docs

#

We already saw people asking what to do, when their console printed Extruder not hot enough

#

So you are totally write. A self supporting environment makes sense, but it's just not fully possible and might make more trouble that needs more time, for a problem that isn't that bad

#

We even got some commands here, but I always forget them 😂 , like
